The SIP protocol update: Eight strategies, incorporating Rapid Peripheral Vein Assessment (RaPeVA), to minimize complications associated with peripherally inserted central catheter insertion

The SaRePo protocol: A seven-step strategy to minimize complications potentially related to the removal of totally implanted central venous access devices

Removal of totally implanted central venous access devices (brachial ports, chest-ports, femoral ports) is potentially associated with the risk of untoward events, some of them negligible (prolonged maneuver time due to technical difficulties), some relevant (hematoma), and some severe (embolization of catheter fragments into the circulation). The removal technique suitable for minimizing such complications has been described only in few manuals, but it has never been standardized. This paper describes a standardized protocol (SaRePo: Safe Removal of Ports) which consists of seven basic strategies to be adopted systematically during removal of totally implanted venous access devices, so to minimize the risk of adverse events. These strategies include: evaluation of the patient's history, preprocedural ultrasound scan of the veins, appropriate aseptic technique, proper local anesthesia, catheter extraction, removal of the reservoir from the pocket, closure of the surgical incision.

Appropriate tourniquet pressure for peripherally inserted central catheter placement in the upper arm

PURPOSE

A peripherally inserted central catheter (PICC) placement often requires ultrasound guidance. Previous studies using an adult blood pressure cuff have suggested that veins do not easily collapse at the tourniquet pressure from diastolic to systolic blood pressure. When inserting a PICC into the basilic vein of the upper arm, a narrow blood pressure cuff should be used as a tourniquet to avoid concealing the puncture site. The aim of this study was to determine the appropriate tourniquet pressure using a narrow cuff when inserting a PICC into the upper arm.

METHODS

We measured the upper arm's blood pressure of seven healthy participants using a pediatric cuff and applied pressure to the upper arm with the pediatric cuff at six levels: 0 mmHg (0), half of the diastolic pressure (D/2), diastolic pressure (D), pressure obtained by combining the systolic and diastolic pressures and dividing by two (DS), systolic pressure (S), and blood pressure as the pulse wave disappears (S + α). An ultrasound probe compressed the basilic vein through the skin. The pressure at which the vein collapsed at each tourniquet pressure was examined.

RESULTS

The venous collapse pressure was higher when the tourniquet pressure was D, DS, or S.

CONCLUSION

D to S is appropriate for PICC placement in the basilic vein of the upper arm in terms of venous collapse.

Prevention of Peripherally Inserted Central Catheter (PICC)-Associated Vein Thrombosis in Cancer: A Narrative Review

Venous thromboembolism (VTE) is considered the most common and potentially life-threatening cardiovascular complication in cancer and the second leading cause of death after cancer progression itself. In recent years, the steadily increasing rate of cancer-associated thrombosis (CAT) seems mainly related to amelioration in imaging techniques and the placements of central venous catheters (CVCs). The pivotal role of CVCs in the switch from hospital to home care is offset by its high thrombotic burden. The peripherally inserted central catheter (PICC) offers advantages (convenience, fast access, and cost-effectiveness) in comparison to centrally inserted devices (PORT), but increased thrombotic risk is reported. The aim of this narrative review was to offer a comprehensive overview of the existing literature about PICC-related thrombosis (PICC-VTE) by analyzing the current knowledge and related gaps. We further discussed advancements in insertion techniques, underscored the role of the novel PICC-PORT lines, and provided a "head-to-head" comparison among major guidelines on primary thromboprophylaxis.

Femoral venous access: State of the art and future perspectives

In the past 5 years, non-dialysis femoral venous access has changed in terms of indications, techniques of insertion, and expected incidence of complications. To the traditional non-emergency indication for femoral catheters-obstruction of the superior vena cava-many other indications have been added, both in intensive and non-intensive care. The insertion technique has evolved, thanks to ultrasound guided venipuncture, tunneling, and ultrasound based intraprocedural tip location. Insertion of femorally inserted central catheters may be today regarded as a procedure with an extremely low intraprocedural and post-procedural risk. The risk of infection is reduced by the possibility of the exit site at mid-thigh, by the use of cyanoacrylate glue for sealing the exit site, and by appropriate intraprocedural strategies of infection prevention. The risk of catheter-related thrombosis is low, due to several concomitant strategies: a proper match between vein diameter and catheter caliber; an accurate intraprocedural assessment of tip location by ultrasound and/or intracavitary ECG; the consistent use of ultrasound guided venipuncture and micro-introducer kits; an adequate stabilization of the catheter at the exit site. The risk of mechanical complications and the risk of lumen occlusion are minimized when using polyurethane, power injectable catheters. All these novelties have brought a revolution in the field of femoral venous access, so that this route may be considered as safe and effective as other approaches to central venous catheterization.

Effective utilisation of rapid infusion catheters in perioperative care: a narrative review

The Rapid Infusion Catheter (RIC) has transformed intravenous (i.v.) access, allowing for rapid fluid delivery peripherally. It may negate the need for a central vein sheath to be placed. This review explores the clinical utility of RICs while addressing technical considerations and potential risks. The RIC is a large-bore i. v. sheath available in two sizes. Its maximal flow rate is 1200 ml min-1, making it advantageous in significant blood loss scenarios such as trauma and major surgeries. Insertion involves the Seldinger technique. Monitoring and maintaining the RIC is crucial to detect and address immediate complications such as occlusions, infiltration, phlebitis, and extravasation of infusate. Although the related complications share similarities with those of other peripheral i. v. cannulae, they have a lower risk of occlusion and accidental displacement. Catheter removal should be considered once the patient is stable or alternative access is available to avoid infectious complications. Removal of the RIC needs to be performed by those educated in RIC management. Maximal flow rate is an essential factor in assessing the performance of i. v. cannulae, and studies have shown that RICs outperform other peripheral and central catheters in this regard. In conclusion, RIC offers advantages over large-bore central venous access for large-volume rapid infusions, including ease of insertion and reduced severe complications. The RIC demonstrates lower thrombosis rates and a different complication profile than peripherally inserted central catheters. Understanding the characteristics and applications of RICs can help healthcare professionals make informed decisions about their use in various medical scenarios.

A novel neonatal protocol for Safe Insertion of Umbilical Venous Catheters (SIUVeC): Minimizing complications in placement and management

Insertion of umbilical venous catheters is a common procedure in neonatal intensive care. Though sometimes lifesaving, this maneuver is potentially associated with early and late complications, some of which may be severe and even life threatening (catheter malposition, hepatic lesions, venous thrombosis, pericardial effusion, etc.). The recent literature suggests several operative strategies that, if adopted systematically, may significantly reduce the incidence of both early and late catheter related complications. This paper describes a standardized protocol (Safe Insertion Umbilical Venous Catheter = SIUVeC) which incorporates such novel strategies, with the goal of minimizing the complications related to this procedure.

The difficult PICC insertion is associated with the significant increase of complications in 1 month follow-up

BACKGROUND

PICC is routinely inserted with assistance of ultrasonography and/or ECG navigation (RI- routine insertion). Only in a minority of patients the insertion of a PICC is difficult and fluoroscopic visualization with introduction of special guidewire is necessary for the success of the procedure (DI-difficult insertion). The aim of the study was to evaluate whether DI can be predicted and associated with a risk of complications during follow-up.

METHODS

The study included patients who had a PICC insertion in 2022. The number of patients with RI and DI was recorded and the significance of selected parameters during insertion and the frequency of complications during 1 month follow-up was compared.

RESULTS

About 1404 patients had successful PICC insertion in 2022, RI in 1360 (96.8%) and DI in 44 patients (3.2%). There was no significant effect of age, gender, selected vein, its size, insertion site, and tunneling on the course of PICC insertion. However the number of punctures for needle insertion was higher in DI. The complication rate during 1 month follow-up in DI was 9 (20.4%) versus 101 patients (7.4%) in RI (p = 0.002).

CONCLUSION

PICC insertion was successful in both RI and DI patients. Of the analyzed parameters, the number of needle punctures was associated with DI, and complications during the 1-month follow-up were more frequently noted in the DI group.

No contraindication to internal jugular central venous catheter insertion in patients at increased risk of bleeding: Results from a prospective observational study in a internal medicine department

Implantation of centrally inserted central venous catheter (CICC) may be complicated by bleedings particularly in patients with severe coagulopathy or taking antithrombotic drugs. It has been shown that the application of the Italian Group for Venous Access Devices (GAVeCeLT) bundle reduces the incidence of bleeding in patients admitted to intensive care units (ICU), but its effectiveness has never been demonstrated in different contexts. In this study we evaluated the incidence of bleeding after urgent internal jugular CICC (J-CICC) implantation in patients with increased or no risk of bleeding complications when recommended preventive strategies are applied systematically. We included 185 patients admitted to Internal Medicine Units who underwent urgent J-CICC implantation from April 2016 to December 2018. The incidence of major and minor bleeding immediately after the procedure and in the following 30 days was recorded. None of the enrolled patients showed major bleeding. The incidence of minor bleedings was 2.1% (95% IC: 0.03-4.2) with two patients requiring line removal and repositioning (1.1%; 95% IC: -0.45 to 2.6). Bleeds were not correlated with age or sex, although they all occurred in female subjects. The incidence of bleeds was not increased in patients with increased risk of bleeding compared with those without (5.0% vs 1.3%; p = 0.16). The use of anti-thrombotic medications was significantly associated with increased risk of minor bleedings (p = 0.03). In this study we demonstrated that the application of the GAVeCeLT suggested bundle can minimize the number of bleeding complications even in patients hospitalized in Internal Medicine Units. Further data are needed in patients taking antithrombotic drugs who appear to be more prone to minor bleeding, however the benefit of completing the procedure appears to significantly outweigh the risk of mechanical complications.

Vascular Access Device Infections: Current Management Practices and the Role of Multidisciplinary Teams at a Large Hospital in Northern Italy

Introduction: Vascular access device (VAD)-associated infections, including catheter-related (CRBSI) and catheter-associated bloodstream infections (CABSI), present significant challenges in patient care. While multidisciplinary VAD teams (VATs) are equipped with protocols for managing these infections, adherence to these guidelines in real-life practice is inconsistent. This study aims to evaluate the alignment between actual VAD infection management practices and VAT-recommended protocols. Methods: We conducted a retrospective, single-center study at Luigi Sacco Hospital (May 2021-October 2023) involving non-ICU adult patients with diagnosed CRBSI or CABSI. VAT experts independently reviewed infection management choices, which were divided into eight specific procedural options. These options included variations in VAD removal, timing of repositioning, and combinations of antimicrobial lock therapy and systemic therapy. Concordance between real-life practices and VAT recommendations was evaluated using Cohen's kappa coefficient. Results: Of 2419 VAD placements, 146 (6%) developed infections (84 CABSI, 62 CRBSI). Clinicians removed VADs in 66.4% of cases compared to 62.3% per VAT recommendations, with moderate overall agreement (Cohen's kappa = 0.58). Analysis of the eight management categories revealed moderate to low alignment (unweighted kappa = 0.44, weighted kappa = 0.30) between real-life practices and VAT guidance, with slightly improved concordance in CRBSI cases. Conclusions: Our findings underscore a discrepancy between real-life VAD infection management and VAT-recommended protocols, suggesting a need for clearer, more accessible guidelines and increased multidisciplinary collaboration. Enhanced VAT consultation and simplified protocol dissemination may improve consistency in infection management and ultimately lead to better patient outcomes.

Can the length of a catheter change the time to bubble at the tip performing the "Bubble Test"? A bench study

INTRODUCTION

Intraprocedural tip control techniques are critical during central venous catheter placement. According to international guidelines (INS 2021), intracavitary electrocardiography is the first method of choice to verify it; when this technique is not feasible, it is considered acceptable to use a contrast-enhanced ultrasound-based tip location method, commonly known as "bubble-test" as an effective alternative.

OBJECTIVE

To assess whether the length of the vascular catheter can alter the time between the injection of the contrast media and its appearance at the catheter tip and the injection duration. Differences between operators stratified according to experience were evaluated as secondary endpoints.

METHODS

A bench study was conducted using an extracorporeal circuit. For each catheter length (60, 40, and 20 cm), three injections were obtained by each of the five operators with different levels of experience for a total of 45 measurements. Differences among operators were evaluated using ANOVA, and the impact of catheter length and operator expertise on times was assessed using repeated measurement models.

RESULTS

Hub-to-tip times of 247.33 ms (SD 168.82), 166 ms (SD 95.46), 138 ms (SD 54.48), and injection duration of 1620 ms (SD 748.58), 1614 ms (SD 570.95), 1566 ms (SD 302.83) were observed for 60, 40, 20 cm catheter length, respectively. A significant time variability between operators was observed. Moreover, moving from 60 to 20 cm, hub-to-tip time was significantly longer for 60 cm devices (p = 0.0124), while little differences were observed for injection duration.

CONCLUSIONS

Catheter length can change both the time between the injection of the contrast media and its appearance at the catheter tip and the injection duration. Hub-to-tip times obtained with 20 and 40 cm and overall injection duration did not differ significantly; skilled personnel could substantially reduce both values analyzed in this study.

Ultrasound-Guided Venous Catheter Placement in Prone Position

The prone position is often used for patients with adult respiratory distress syndrome and specific surgical postures. When performing venous cannulation in this position, it is important to have a structured review to introduce the available major veins and ultrasound-guided procedure. In this review, we discuss the techniques of ultrasound-guided cannulation and provide insights into various aspects, including the anatomical locations of veins, vein sizes, placement techniques, surrounding structures at risk, and reported experiences with catheter placements. Eight major veins can be accessed in the prone position: the internal jugular vein, external jugular vein, brachiocephalic vein, basilic vein, mid-thigh femoral vein, popliteal vein, posterior tibial vein, and small saphenous vein. To minimize the risk of venous thromboembolism, the ratio of catheter diameter to vessel diameter should be less than 0.67. The review also presents the minimal requirement of venous diameter for different catheters in a tabulated form. For larger veins, real-time ultrasound guidance with the long-axis view/in-plane technique is suggested, while for smaller vessels, the short-axis view/out-of-plane technique is recommended. The review includes sonographic illustrations of the two techniques and surrounding arteries and nerves for the eight major veins. The aim of this review is to help clinicians assess the eight major veins and safely insert various types of catheters for patients in the prone position.

Nursing Interventions to Prevent Complications in Patients with Peripherally Inserted Central Catheters: A Scoping Review

Background: A Peripherally Inserted Central Catheter (PICC) is a safe and effective Central Vascular Access Device when properly used. Therefore, it has become an increasingly frequent procedure. Nurses are often the professionals responsible for its insertion, maintenance, and removal. Despite the advantages of this device, it presents risks and possible associated complications. This scoping review aims to identify and analyze nursing interventions to prevent complications in adults with PICC. Methods: The review was conducted according to Joanna Briggs Institute's scoping review proposal. The electronic databases Pubmed, CINAHL Complete, MEDLINE Complete, Cochrane Central Register of Controlled Trials, Nursing & Allied Health Collection: Comprehensive, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Library, Information Science & Technology Abstracts, and MedicLatina were consulted in October 2023. Additionally, we searched the websites of the Registered Nurses Association of Ontario and the Canadian Vascular Access Association. We included articles published in English and Portuguese between 2018 and 2023. Results: A total of 170 articles were initially identified. After selecting and analyzing the articles, 13 studies were included. This review identified nursing interventions in adults to prevent PICC-related complications, categorized into five main groups: pre-procedure, during the procedure, post-procedure, maintenance, and team management interventions. Nurses are pivotal in averting PICC complications by employing evidence-based nursing interventions at each process stage. Conclusions: The importance of nursing interventions in enhancing patient safety, improving health outcomes, and informing clinical practice highlights the need for standardized protocols, specialized training, and consistent patient education for PICC care.

Chinese expert consensus on tunneled technique for peripherally inserted central venous catheters

OBJECTIVE

To formulate an expert consensus on an evidence-based overview of all topics related to the Tunneled Peripherally Inserted Central Venous Catheters.

METHODS

A Chinese consensus based on evidence has provided a definition and indications for Tunneled Peripherally Inserted Central Venous Catheters. The literature on Tunneled Peripherally Inserted Central Venous Catheter was reviewed from its inception to March 2024. The indications were developed using the RAND/UCLA Appropriateness Method.

RESULTS

This consensus presents five indications for Tunneled Peripherally Inserted Central Venous Catheters, covering tunneling definitions, key processes, tunneling devices, various applications, and maintenance. The indications aim to enhance patient safety and optimize the efficacy of tunneled peripherally inserted central venous catheters.

CONCLUSIONS

This consensus is based on critical evidence review and the clinical experts aimed to assist clinicians in applying tunneling techniques. Further prospective studies are needed to evaluate the impact of complications related to the tunneling technique.

Pseudo-tunneling procedure for PICC-Ports catheters insertion in patients with small veins at the middle third of the arm

BACKGROUND

Axillary vein in the brachial tract or Basilic vein in the proximal third of the arm usually present a diameter wide enough to receive a catheter of 5 Fr. Therefore, a peripherally inserted central catheters with port (PICC-Ports) cannot be positioned in these areas. Pseudo-tunneling procedure allows the positioning of the Port in the middle part of the arm without using tunnelers during insertion of PICC with Port in patients who present deep veins of the arm too small to receive a PICC-Port catheter. The aim of this study was to present our experience with pseudo-tunneling procedure during the positioning of the PICC-Port, while using a particular variation of the technique already described for PICCs and midline.

METHODS

From January to December 2023, 103 PICC-Ports were placed in adult patients. Ninety catheters were tunneled from the puncture of the axillary vein at the proximal arm point, while we used this new technique in 42 patients by the same trained team of Vascular Access Unit at ASST Spedali Civili Hospital of Brescia.

RESULTS

All procedures were successfully performed at the first attempt. No insertion related complications were observed.

CONCLUSIONS

Our data suggest pseudo-tunnelling is a safe and effective technique for PICC-Ports insertion avoiding central venous catheterization, even in patient with small vein at the arms.

The Midline Catheter Within the Context of Home Intravenous Antibiotic Treatment

Home intravenous antibiotic treatment (HIAT) consists of the administration of intravenous antibiotic therapy in the home of the patient. Short peripheral intravenous catheters have long been the first option for antimicrobial therapies. However, these devices are known for their short durability. At present, the midline catheter is one of the median duration devices most commonly used and recommended within the context of HIAT. The objective of this study was to evaluate the occurrence of complications related to midline catheters implanted by a vascular access team in patients undergoing HIAT within the context of home hospitalization. This was a prospective observational study, which consecutively included 77 patients. A total of 92 midline catheters were analyzed. The complications observed were device obstruction (8.7%), infiltration (3.3%), dislodgement (2.2%), and thrombosis (1.1%). Bivariate analysis showed that the pH of the drug and ertapenem administration were associated with catheter obstruction. The authors found a low prevalence of midline catheter-associated complications in patients undergoing HIAT. The use of antireflux needleless connectors should be considered to reduce obstructions. In addition, algorithms that include the variable of type of daily life activity should be developed for deciding the most appropriate catheter for home hospitalized patients receiving HIAT.

Comparison of procedure-related pain and patient satisfaction according to catheter size and insertion site in peripheral intravenous catheterization

BACKGROUND

Peripheral intravenous catheterization is a painful and uncomfortable procedure and is the most commonly used invasive procedure in healthcare institutions. Compare procedure-related pain and patient satisfaction according to catheter size and insertion site in peripheral intravenous catheterization.

METHODS

The study was comparative prospective randomized study. Individual Information Form, Visual Analog Scale, and Patient Satisfaction Scale about Catheterization were used for data collection.

RESULTS

The highest pain score and the lowest patient satisfaction were determined in 20 gage insertion in the dorsum of the hand. It was less painful to perform the procedure in the forearm than in the dorsum of the hand. Moreover, there was a significant negative correlation between the level of pain experienced due to peripheral intravenous catheterization and patient satisfaction with catheterization.

CONCLUSIONS

A smaller peripheral intravenous catheter inserted in the forearm resulted in less pain sensation and higher patient satisfaction.

Pseudo-tunneling procedure: An easy technique for insertion of PICCs and Midline catheters in patients with small veins of the arm

BACKGROUND

Axillary vein in the brachial tract or Basilic vein in the proximal third of the arm has got usually an enough diameter to receive a catheter of 4 or 5 Fr. In this case the exit site should be too proximal to the axilla with an higher risk of infection. Pseudo-tunneling procedure can create an exit site at the middle of the arm without using tunnelers during insertion of Peripherally Inserted Central Catheters and Midlines in patients who present deep veins of the arm too small to receive a catheter to consent infusion and blood samples.

AIM

The aim of this study is to present our experience with pseudo-tunneling procedure, also using a particular variation of the technique.

METHODS

From January 2014 to August 2022 150 Peripherally Inserted Central Catheters and 221 Midlines were insert in pediatric and adults patients with too small deep veins at the middle third of the arm with this technique by the same trained team of Vascular Access Unit at ASST Spedali Civili Hospital of Brescia.

RESULTS

All procedures were successfully performed at the first or at the second attempt. No insertion related complications were observed.

CONCLUSIONS

Our data suggest pseudo-tunneling technique is a safe and effective procedure for of Peripherally Inserted Central Catheters and Midline insertion avoiding central venous catheterization even in patient with small vein at the arms.

A GAVeCeLT bundle for PICC-port insertion: The SIP-Port protocol

In the last decade, a new type of brachial port has been introduced in clinical practice, the so-called "PICC-port." This is a brachial port, but inserted according to the methodologies and technologies currently adopted for the insertion of peripherally inserted central catheters (PICCs). Several studies have shown that PICC-port insertion is safe, not associated with any relevant immediate or early complication, and that the expected incidence of late complications is significantly lower if compared to "traditional" brachial ports (i.e. inserted without ultrasound guidance). Furthermore, PICC-ports yield excellent esthetic results and are associated with optimal patient compliance. This paper describes an insertion bundle-developed by GAVeCeLT, the Italian Group of Long Term Venous Access Devices, and nicknamed "SIP-Port" (Safe Insertion of PICC-Ports)-which consists of few evidence-based strategies aiming to further minimize all immediate, early, or late complications potentially associated with PICC-port insertion. Also, this insertion bundle has been developed for the purpose of defining more closely the differences between a traditional brachial port and a PICC-port. The SIP-Port bundle is currently adopted by all training courses on PICC-port insertion held by GAVeCeLT. It includes eight steps: (1) preprocedural ultrasound assessment utilizing the RaPeVA (Rapid Peripheral Venous Assessment) protocol; (2) appropriate skin antiseptic technique and maximal barrier precautions; (3) choice of appropriate vein, in terms of caliber and site; (4) clear identification of the median nerve and of the brachial artery during the venipuncture; (5) ultrasound-guided puncture and cannulation of the vein; (6) ultrasound-guided tip navigation; (7) intra-procedural assessment of tip location by intracavitary ECG or by trans-thoracic echocardiography; (8) appropriate creation and closure of the subcutaneous pocket.

The longer the catheter, the lower the risk of complications: Results of the HERITAGE study comparing long peripheral and midline catheters

BACKGROUND

Although widely used in clinical practice, long peripheral (LPCs) and midline catheters (MCs) are often misclassified because of their similar characteristics. Comparative studies on these devices are lacking. This study aimed to explore complications risks in polyurethane LPCs and MCs.

METHODS

Prospective cohort study. Catheter-failure within 30days was the primary outcome, catheter-related bloodstream infection (CR-BSI), thrombosis, and fibroblastic sleeve were secondary outcomes. The average number of drugs infused per day was computed to measure the overall intensity of catheters' use.

RESULTS

The catheter-failure incidence was 5.7 and 3.4/1,000 catheter-days for LPCs and MCs, respectively. MCs were associated with an adjusted lower risk of catheter-failure (hazard ratio 0.311, 95% confidence interval 0.106-0.917, P = .034). The daily number of drugs infused was higher for MCs (P < .001) and was associated with a greater risk catheter-failure risk (P = .021). Sensitivity analysis showed a decreased catheter-failure risk for MCs starting from day-10 from positioning. The incidence of CR-BSI (0.9 vs 0.0/1,000 catheter-days), thrombosis (8.7 vs 3.5/1,000 catheter-days), and fibroblastic sleeve (14.0 vs 8.1/1,000 catheters-days) was higher for LPC catheters.

CONCLUSIONS

Despite more intensive drug administration, MCs were associated with a longer uncomplicated indwelling time.

Safety and complications associated with tunneling and pseudotunneling techniques during PICC and Midline insertion

INTRODUCTION

Peripherally Inserted Central Catheters and Midline Catheters are particularly attractive because of their favorable risk/benefit ratio. If the ideal venipuncture site is in an area inappropriate for catheter emergence, a valid alternative is the tunneling technique, which allows the exit site to be moved to reach the optimal position. There are two main types of tunneling techniques: standard tunnel, using a tunneling device (metal tunneler or peel-away tunneler), and pseudo-tunnel. As much as both are recognized as appropriate and safe, there are still few literature data indicating the criteria for choosing and using the two techniques and the possible related complications.

METHODS

This retrospective observational investigation analyzed data regarding intra- and post-procedural complications of tunneled catheters inserted using two different techniques. The sample was stratified into three subgroups: (1) Standard Tunnel (patients with no PLT or INR disorders), (2) Pseudotunnel (patients with no PLT or INR disorders), and (3) Pseudotunnel (patients with any PLT or INR disorder). Data regarding the procedure, at 24 h and 7 days were collected and analyzed.

RESULTS

A total of 143 patients who underwent tunneled catheter insertion were included in the study. Among these, 113 patients were divided into subgroups 1 and 2 and 30 were assigned to subgroup 3. No significant differences were found among the three subgroups regarding immediate, short, and medium-term tunnel complications.

CONCLUSIONS

The findings of this study suggest that both standard and pseudo-tunnels provide comparable levels of safety and comfort for patients. It was noted that Pseudotunnel offers an equivalent level of safety for patients with coagulation disorders related to PLT and INR, rendering it comparable to a "minimally invasive procedure," which necessitates the same precautions as a non-tunneled PICC.

Clinical outcomes of peripherally inserted central catheters in patients with gastroenterological diseases: Report of a 9-year experience

BACKGROUND

Peripherally inserted central catheters (PICCs) are safe and useful alternatives to centrally inserted central catheters (CICCs). Several studies have investigated the effectiveness and safety of PICCs; however, few have focused on their use in patients with gastroenterological diseases. In the present study, we evaluated the outcomes of patients with gastroenterological diseases who received PICCs and identified the risk factors associated with central line-associated blood stream infection (CLABSI).

METHODS

We retrospectively examined hospitalized patients at our institution who received PICCs between 2015 and 2023. We evaluated the data on their clinical characteristics, complications, and outcomes. Furthermore, we investigated the risk factors for CLABSIs.

RESULTS

A total of 405 patients were included (262 men and 143 women). The median age was 71 (range, 15-94) years. The vessels were inserted in the basilic, cephalic, and brachial veins in 366 (90%), 22 (6%), and 17 (4%) patients, respectively. The median procedure time was 32 [6-149] min. The median dwell time was 16 [0-188] days. CLABSI, catheter occlusions, phlebitis, and exit-site skin infection occurred in 14 (3.5%; 1.77/1000 catheter days), 6 (1.5%; 0.76/1000 catheter days), 3 (0.7%; 0.38/1000 catheter days), and 1 (0.2%; 0.13/1000 catheter days) patients, respectively. There was no case of deep vein thrombosis or pulmonary thrombosis due to PICC placement. Multivariate analysis performed using a Cox's proportional hazard regression model revealed that patients with gastroenterological malignancies had an independently higher risk for CLABSIs (odds ratio [OR]: 3.25, 95% confidence interval [CI]: 1.05-10.05, p = 0.041) and that older age (⩾70 years) tended to be associated with CLABSIs (OR: 3.61, 95% CI: 0.98-13.32, p = 0.054).

CONCLUSIONS

Gastroenterological malignancies and older age were associated with a higher risk of CLABSIs. Rigorous catheter management is crucial for preventing complications, particularly in vulnerable patient subgroups.

Experience of a vascular ultrasound-guided program: from the ICU to the hospital

BACKGROUND

The use of peripherally inserted central venous catheters (PICCs) has increased worldwide in the last decade. However, PICCs are associated to catheter-related thrombosis (CRT) and central line-associated bloodstream infections (CLABSIs). We describe the characteristics of patients requiring a PICC, estimate the incidence rate, and identify potential risk factors of PICC-related complications.

METHODS

All adult patients requiring a PICC at our institution (Fundación Santa Fe de Bogotá, Bogota, Colombia) from September 2022 to May 2024 were included in the analysis. The database from active PICC monitoring collected demographic and PICC-related information. The incidence rate of CLABSI and CRT, and crude odds ratios (cORs) were estimated.

RESULTS

Overall, 1936 individuals were included in the study. The median age was 67 years (IQR: 50-78 years), and 51.5% were females. The median duration of PICC lines was 10 days (IQR: 4-17). Seventy-nine patients had catheter-related complications, mostly in the Intensive Care Unit (ICU). The CLABSI and CRT institutional incidence rates per 1000 catheter-days were 2.03 (2.96 in the ICU) and 0.58 (0.61 in the ICU), respectively. Prolonged catheter use (≥ 6 days), PICC insertion in the intensive care unit, and postoperative care after cardiac surgery were identified as potential risk factors for CLABSI, while a catheter insertion into the brachial vein was associated with CRT.

CONCLUSION

Daily PICC assessment, particularly in patients with prolonged catheter use, PICC insertion into the brachial vein, or in postoperative care after cardiac surgery may significantly reduce CLABSI and CRT cases. Implementing Vascular Access Teams, venous catheter care bundles, and institutional insertion protocols optimize clinical outcomes.

Training for ultrasound-guided implantation of central venous catheters eliminates venolysis in pediatric patients

BACKGROUND

In the pediatric setting, the procurement of vascular access can be particularly difficult. Surgical venolysis was the first technique described but, in recent years, the literature has shown that ultrasound-guided implantation has fewer complications. The principal aim of this paper is to state how after a structured training to place ultrasound-guided central lines, venolysis was definitively abandoned in our hospital. We also analyzed the impact of training on the duration of procedures. Finally, the number of procedures performed per operator to maintain the quality standard achieved.

METHOD

In this observational retrospective study, we analyzed data from 2013 to 2020 of 1497 pediatric and neonatal central venous access placements in a single center during a training path.

RESULTS

Venolysis performed by the pediatric surgeons was used in 11% of total placements, the most in the smallest patients (76.1%, <1 year of age). With the implementation of training, this invasive technique became obsolete to the point where it was no longer practiced (24.6% of vascular placement in 2013 to 0% in 2020). In the placement performed by the pediatric anesthesiologists, time progressively decreased from 51.5 min in 2013 to 29.4 min in 2022. From the analysis of the number of procedures performed by pediatric anesthesiologists, the first consultant involved performed averaging 48 procedures per year, while the other consultants had an overall average of 16.7-25 placements per year.

CONCLUSION

Echo-guided vascular cannulation was found to be safe, reliable, and reproducible in pediatric patients and neonates and permits to deletion definitively venolysis. Well-structured training is essential and should be standardized in the future.

Quality of life in women with breast cancer undergoing neoadjuvant chemotherapy: comparison between PICC and PICC-port

BACKGROUND

Peripherally inserted central catheters (PICCs) and new type of arm-port, the PICC-port, are currently used for neoadjuvant chemotherapy treatment in patients with breast cancer. We aimed to compare Quality of Life (QoL) of patients receiving one of these two devices investigating overall satisfaction, psychological impact, as well as the impact on professional, social and sport activities, and local discomfort.

METHODS

We did a prospective observational before-after study of PICCs versus PICC-ports. Adult (aged ≥ 18 years) females with breast cancer candidate to neoadjuvant chemotherapy were included. The primary outcome was QoL according to the Quality-of-Life Assessment Venous Device Catheters (QLAVD) questionnaire assessed 12 months after device implantation.

RESULTS

Between May 2019 and November 2020, of 278 individuals screened for eligibility, 210 were enrolled. PICC-ports were preferred over PICCs with a QLAVD score of 29 [25; 32] vs 31 [26; 36.5] (p = 0.014). Specifically, most QLAVD constructs related to psychological impact, social aspects, and discomfort were in favor of PICC-ports vs PICC, especially in women under the age of 60. Overall, pain scores at insertion and during therapy administration were not significantly different between the two groups, as well as infection, secondary malpositioning, thrombosis, or obstruction of the device.

CONCLUSIONS

In women with breast cancer undergoing neoadjuvant chemotherapy, PICC-ports were overall better accepted than PICCs in terms of QoL, especially in those who were younger. Device-related complications were similar.

Safe Insertion of Arterial Catheters (SIA): An ultrasound-guided protocol to minimize complications for arterial cannulation

Direct puncture and cannulation of peripheral arteries is frequently performed in critical care and in emergency settings, mainly for hemodynamic monitoring and blood sampling. While there is abundant literature on peripheral arterial cannulation in children and adults, there is still scope for clinical improvements which may impact on patient safety. Although the radial artery is the most frequently utilized access site today, due to its superficial proximity, ease of access, and low risk of adverse events, other sites are sometimes chosen. The authors propose the Safe Insertion of Arterial Catheters (SIA) protocol, an ultrasound-guided insertion bundle applying a systematic approach to arterial cannulation, with a focus on improving insertion practices, reducing procedural complications, increasing the patient safety profile, and improving device performance.

Midline catheters for blood gas and acid/base monitoring in critical patients: A prospective observational study

BACKGROUND

Arterial lines and central venous catheter (CVC) allow to monitor patients' acid-base status and gas exchange. Their placement and maintenance may however be burdened by severe complications. Midline Catheters (MC) are peripheral venous accesses that are less invasive and easier to insert compared to CVC and arterial lines.

METHODS

A prospective observational study was performed including stabilized critical patients with clinical indication to midline positioning before intensive care unit (ICU) discharge. The primary aim was to assess if venous sampling from MCs can be a reliable alternative to CVC for pH and CO2 monitoring. The secondary aim was to evaluate the correlation between samplings from MC, CVC and arterial line with regards to pH, carbon dioxide tension (pCO2), lactates and electrolytes. Three samples from CVC, arterial line and MC were collected simultaneously. Agreement and correlation of the studied parameters between different sampling sites were explored.

RESULTS

40 patients were included in the analysis. A good agreement for pH and pCO2 was recorded between MC and CVC: mean differences were 0.001 (95% CI -0.006 to 0.007) and 0.7 (-0.1 to 1.5), percentage error 0.4% and 11.2%, respectively. Correlation between MC and both central venous and arterial samples for pH, pCO2, lactates and electrolytes was found to be moderate-to-strong (Pearson's R coefficient range 0.59-0.99, p < 0.001 for all these parameters).

CONCLUSIONS

In stabilized critical patients, midline catheters represent a reliable alternative to CVC and arterial lines to monitor acid-base disturbances, CO2 levels and electrolytes. The present findings add to the known advantages of MC, which might be considered a first-line vascular access for non-critical or stabilized patients who do not require infusion of vesicant or irritant drugs.

A new wireless device for bedside assessment of tip location of central venous access devices using intracavitary ECG: A retrospective study

Intracavitary electrocardiography (IC-ECG) is a non-invasive method for intraprocedural tip location during central venous catheterization. Over the last 20 years, the IC-ECG method has been thoroughly investigated and many studies have confirmed its wide applicability and feasibility, as well as its great accuracy and safety in different populations of patients and in different types of central venous access devices (CVADs). This retrospective study presents a two-center experience with tip location of central venous catheters using IC-ECG, by means of a new wireless portable device. Tip location was performed during 983 insertions of CVADs at bedside, using this new device. Clinical conditions with limited or no applicability of IC-ECG were excluded. The feasibility of IC-ECG, as performed using the novel device, was 92.2%. This wireless device may play an important role in central venous catheterization at bedside, since it is pocket-sized, particularly easy to use, and easy to sanify after use.

Impact of a 'Catheter Bundle' on Infection Rates and Economic Costs in the Intensive Care Unit: A Retrospective Cohort Study

INTRODUCTION

Catheter-related infections (CBRSIs) are a widespread problem that increase morbidity and mortality in intensive care unit (ICU) patients and management costs.

OBJECTIVE

The main aim of this study was to assess the prevalence of CBRSIs in an intensive care unit following international literature guidelines for managing vascular lines in critically ill patients. These guidelines include changing vascular lines every 7 days, using needle-free devices and port protectors, standardising closed infusion lines, employing chlorhexidine-impregnated dressings, and utilising sutureless devices for catheter securement.

MATERIALS AND METHODS

This single-centre retrospective observational study was conducted in a general Italian ICU. This study included all eligible patients aged > 1 year who were admitted between January 2018 and December 2022.

RESULTS

During the study period, 1240 patients were enrolled, of whom 9 were diagnosed with a CRBSI. The infection rate per 1000 catheters/day was as follows: femorally inserted central catheter, 1.04; centrally inserted central catheter, 0.77; pulmonary arterial catheter 0.71, arterial catheter, 0.1; and peripherally inserted central catheter and continuous veno-venous haemodialysis dialysis catheters equal to 0. No difference in CRBSI was observed between the years included in the study (p = 0.874). The multivariate analysis showed an association between the diagnosis of CBRSI and Nursing Activities Score (per single point increase β = 0.04-95%CI: -0.01-0.09, p = 0.048), reason for ICU admission-trauma (β = 0.77-95%CI: -0.03-1.49, p = 0.039), and use of therapeutic hypothermia (β = 2.06, 95%CI: 0.51-3.20, p < 0.001). Implementing the study protocol revealed a cost of EUR 130.00/patient, equivalent to a daily cost of EUR 15.20 per patient.

CONCLUSIONS

This study highlights the importance of implementing a catheter care bundle to minimise the risk of CRBSI and the associated costs in the ICU setting. A policy change for infusion set replacement every 7 days has helped to maintain the CRBSI rate below the recommended rate, resulting in significant cost reduction and reduced production of ICU waste.

Epidemiology and Clinical Insights of Catheter-Related Candidemia in Non-ICU Patients with Vascular Access Devices

INTRODUCTION

Vascular access devices (VADs), namely peripheral VADs (PVADs) and central venous VADs (CVADs), are crucial in both intensive care unit (ICU) and non-ICU settings. However, VAD placement carries risks, notably catheter-related bloodstream infections (CRBSIs). Candida spp. is a common pathogen in CRBSIs, yet its clinical and microbiological characteristics, especially in non-ICU settings, are underexplored.

METHODS

We conducted a monocentric, retrospective observational study at Luigi Sacco Hospital from 1 May 2021 to 1 September 2023. We reviewed medical records of non-ICU adult patients with CVADs and PVADs. Data on demographics, clinical and laboratory results, VAD placement, and CRBSI occurrences were collected. Statistical analysis compared Candida spp. CRBSI and bacterial CRBSI groups.

RESULTS

Out of 1802 VAD placements in 1518 patients, 54 cases of CRBSI were identified, and Candida spp. was isolated in 30.9% of episodes. The prevalence of CRBSI was 3.05%, with Candida spp. accounting for 0.94%. Incidence rates were 2.35 per 1000 catheter days for CRBSI, with Candida albicans and Candida non-albicans at 0.47 and 0.26 per 1000 catheter days, respectively-patients with Candida spp. CRBSI had more frequent SARS-CoV-2 infection, COVID-19 pneumonia, and hypoalbuminemia.

CONCLUSIONS

During the COVID-19 pandemic, Candida spp. was a notable cause of CRBSIs in our center, underscoring the importance of considering Candida spp. in suspected CRBSI cases, including those in non-ICU settings and in those with PVADs.

A GAVeCeLT consensus on the indication, insertion, and management of central venous access devices in the critically ill

Central venous access devices are essential for the management of critically ill patients, but they are potentially associated with many complications, which may occur during or after insertion. Many evidence-based documents-consensus and guidelines-suggest practical recommendations for reducing catheter-related complications, but they have some limitations. Some documents are not focused on critically ill patients; other documents address only some special strategies, such as the use of ultrasound; other documents are biased by obsolete concepts, inappropriate terminology, and lack of considerations for new technologies and new methods. Thus, the Italian Group of Venous Access Devices (GAVeCeLT) has decided to offer an updated compendium of the main strategies-old and new-that should be adopted for minimizing catheter-related complications in the adult critically ill patient. The project has been planned as a consensus, rather than a guideline, since many issues in this field are relatively recent, and few high-quality randomized clinical studies are currently available, particularly in the area of indications and choice of the device. Panelists were chosen between the Italian vascular access experts who had published papers on peer-reviewed journals about this topic in the last few years. The consensus process was carried out according to the RAND/University of California at Los Angeles (UCLA) Appropriateness Methodology, a modification of the Delphi method, that is, a structured process for collecting knowledge from groups of experts through a series of questionnaires. The final document has been structured as statements which answer to four major sets of questions regarding central venous access in the critically ill: (1) before insertion (seven questions), (2) during insertion (eight questions), (3) after insertion (three questions), and (4) at removal (three questions).

Central venous catheter-related thrombosis in patients with amyotrophic lateral sclerosis

BACKGROUND

Central venous catheterization may be required in patients with amyotrophic lateral sclerosis (ALS) for parenteral nutrition, antibiotic treatment, or blood sampling. Different venous access devices can be taken into consideration-centrally inserted central catheters (CICC), peripherally inserted central catheters (PICC), and femorally inserted central catheters (FICCs)-depending on the clinical conditions of the patients. Regardless of the type of access, the presence of paraplegia or tetraplegia is commonly considered a risk factor for catheter-related thrombosis (CRT).

METHOD

This retrospective study analyzes the rate of CRT and other non-infectious complications associated with central venous access in a cohort of 115 patients with paraplegia or tetraplegia, most of them affected by ALS (n = 109).

RESULTS

In a period of 34 months, from January 2021 to October 2023, we inserted 75 FICCs, 29 CICCs, and 11 PICCs. PICCs were inserted only in patients with preserved motility of the upper limbs. All devices were inserted by trained operators adopting appropriate insertion bundles. We had no immediate or early complication. Though antithrombotic prophylaxis was adopted only in 61.7% of patients, we had no symptomatic CRT. Other non-infectious complications were infrequent (4 out of 115 patients).

CONCLUSION

These results suggest (a) that the presence of paraplegia or tetraplegia is not necessarily associated with an increased risk of CRT, (b) that the adoption of well-designed insertion bundles plays a key role in minimizing non-infectious complications, and (c) that the insertion of FICCs by direct cannulation of the superficial femoral vein at mid-thigh in paraplegic/tetraplegic patients may have the same advantages which have been described in the general population.

A narrative review on tip navigation and tip location of central venous access devices in the neonate: Intracavitary ECG or real time ultrasound?

The proper location of the tip of a central venous access device plays a crucial role in minimizing the risks potentially associated with its use. Recent guidelines strongly recommend preferring real-time, intra-procedural methods of tip location since they are more accurate, more reliable and more cost-effective than post-procedural methods. Intracavitary electrocardiography and real time ultrasound can both be applied in the neonatal setting, but they offer different advantages or disadvantages depending on the type of central venous access device. Reviewing the evidence currently available about the use of these two methods in neonates, in terms of applicability, feasibility and accuracy, it can be concluded that (a) real time ultrasound is the only acceptable methodology for tip navigation for any central venous access device in neonates, (b) intracavitary electrocardiography is the preferred method of tip location for central catheters inserted by ultrasound-guided cannulation of the internal jugular vein or the brachiocephalic vein, and (c) real time ultrasound is the preferred method of tip location for umbilical venous catheters, epicutaneo-cava catheters, and central catheters inserted by ultrasound-guided cannulation of the common femoral vein.

A decision-making algorithm proposal for PICCs and midlines insertion in patients with advanced kidney disease: A pilot study

INTRODUCTION

Kidney Disease Outcomes Quality Initiative clinical practice guidelines recommend avoiding placement of peripherally inserted vascular access devices in patients with an estimated glomerular filtration rate (eGFR) <45 ml/min. On the other hand, many patients with severe chronic kidney disease (CKD) have poor prognosis.This study carried out a global assessment of mortality at 2 years through Charlson Comorbidity Index (CCI) and Beclap score in patients with PICCs or Midlines, assuming that in those with an estimated high mortality rate at 2 years, it could be acceptable to implant a peripheral vascular access device (PVAD) despite the presence of CKD.

METHODS

We analyzed data on patients with PICCs or Midlines inserted from October 2018 to November 2019. CCI, Beclap score, and eGFR were calculated for each patient at the time of the catheter insertion. We then followed patients for 2 years to assess 2-year mortality for each.

RESULTS

One hundred and thirty-one patients were enrolled, 49 (37.4%) had eGFR<45 ml. The 2-year mortality rate was 57.3%. The cut off derived from ROC curve analysis of 15 for Beclap score and 5 for CCI, showed good sensitivity and specificity in predicting mortality of the total population, patients without an oncological disease and patients with eGFR<45 ml/min.

CONCLUSION

CCI and Beclap score are good predictors of mortality at 2 years.Physicians and nurses can use these tools in the evaluation of patients at risk for future dialysis, instead of relying exclusively on renal function to decide whether implanting PICCs, Midlines, or other vascular access devices.

Caliber of the deep veins of the arm in infants and neonates: The VEEIN study (Vascular Echography Evaluation in Infants and Neonates)

PURPOSE

Ultrasound-guided peripherally inserted central catheters (PICCs) are increasingly used in children, though their insertion may be limited by the small caliber of the deep veins of the arm. Previous studies have suggested to use age or weight as a guide to the feasibility of PICC insertion. We have planned an observational study with the purpose of identifying the actual feasibility of PICC insertion based on the ultrasound evaluation of the deep veins of the arm in groups of children of different weight range.

METHODS

We have studied 252 children weighing between 2.5 and 20 kg, divided in five different groups (group 1: 2.5-4 kg; group 2: 4.1-7 kg; group 3: 7.1-10 kg; group 4: 10.1-15 kg; group 5: 15.1-20 kg): the caliber of brachial vein, basilic vein, and cephalic vein at mid-upper arm + the caliber of the axillary vein at the axilla were measured by ultrasound scan.

RESULTS

Veins of caliber >3 mm (appropriate for insertion of a 3 Fr non-tunneled PICC) were found at mid-upper arm in no child of group 1 or 2, in 13% of group 3, in 28% of group 4, and in 54% of group 5. An axillary vein >3 mm (appropriate for insertion of a 3 Fr tunneled PICC) were found in 5.8% of group 1, 30.6% of group 2, 67% of group 3, 82% of group 4, and 94% of group 5.

CONCLUSIONS

The age and the weight of the child have a small role in predicting the caliber of the veins of the arm. Veins should be measured case by case through a proper and systematic ultrasound evaluation; however, the clinician can expect that insertion of a 3 Fr PICC may be feasible in one third of children weighing between 4 and 7 kg, and in most children weighing more than 7 kg, especially if adopting the tunneling technique.

Impact of distance of the catheter tip from cavo-atrial junction on bubble test (delay) time: A prospective study

INTRODUCTION

Correct tip positioning is a critical aspect in central vascular access devices insertion. The verification of positioning at the cavo-atrial junction is usually performed by intracavitary electrocardiography. Recently, echocardiographic techniques were proposed, including the direct visualization of the catheter or the visualization of a saline/air bolus (i.e. "bubble test"). As for the latter, a push-to-bubbles delay time below 2 s was proposed to indicate a correct positioning of the catheter tip. The aim of this study was to measure the variations of the push-to-bubbles time at increasing distance from the cavo-atrial junction, to verify if a cut-off of 1-2 s correspond to a well-positioned catheter.

METHODS

We performed a prospective study including patients with clinical indication of positioning a peripherally inserted central catheter. The catheter tip was positioned at the cavo-atrial junction (P0) via intracavitary electrocardiography, and the push-to-bubbles delay time was measured. The catheter was then retracted 5 cm (P1) and 10 cm (P2), and the test was repeated at this positioning. Push-to-bubbles time measurements were performed off-line by analyzing an audio/video recording which included the echography screen and the voice signal of the operator.

RESULTS

Forty-nine patients were included. The average push-to-bubble time when the catheter tip was in the reference position was 0.41 ± 0.21 s. Retraction of the PICC catheter of 5 and 10 cm determined a significant increase of the push-to-bubbles time: mean time difference was +0.34 (95% IC 0.25-0.43, p < 0.001) s between P0 and P1 (5 cm distance), and +0.77 (95% IC 0.62-0.92, p < 0.001) s between P0 and P2 (10 cm distance). When the catheter was at the reference position (i.e. cavo-atrial junction) only 2.1% of bubbles delay times were above 1 s.

CONCLUSION

The push-to-bubbles time is very low when the catheter tip is at the cavo-atrial junction. This delay increases progressively with increasing distance from the target. Push-to-bubbles delay time above 1 s might indicate a catheter not close to the cavo-atrial junction.

The pediatric DAV-expert algorithm: A GAVeCeLT/GAVePed consensus for the choice of the most appropriate venous access device in children

In pediatric patients, the choice of the venous access device currently relies upon the operator's experience and preference and on the local availability of specific resources and technologies. Though, considering the limited options for venous access in children if compared to adults, such clinical choice has a great critical relevance and should preferably be based on the best available evidence. Though some algorithms have been published over the last 5 years, none of them seems fully satisfactory and useful in clinical practice. Thus, the GAVePed-which is the pediatric interest group of the most important Italian group on venous access, GAVeCeLT-has developed a national consensus about the choice of the venous access device in children. After a systematic review of the available evidence, the panel of the consensus (which included Italian experts with documented competence in this area) has provided structured recommendations answering 10 key questions regarding the choice of venous access both in emergency and in elective situations, both in the hospitalized and in the non-hospitalized child. Only statements reaching a complete agreement were included in the final recommendations. All recommendations were also structured as a simple visual algorithm, so as to be easily translated into clinical practice.

Required volume for color flow injection test to confirm the intravascular placement of a peripheral venous catheter

BACKGROUND

Confirmation of adequate peripheral intravenous catheter placement is essential before using venous catheters. The color flow injection test has been reported as a method with high sensitivity and specificity for this purpose. The technique involves administrating saline through the peripheral venous route to observe changes in the color flow pattern around the same vein at a more central location. However, the required volume of saline remains uncertain. This study aims to determine the appropriate dosage for conducting the test in pediatric patients and explore any potential correlations between dosage and patient characteristics.

METHODS

A prospective study was conducted in children under 6 years of age with American Society of Anesthesiologists Physical Status 1-2 presenting for general anesthesia. After an intravenous cannula was placed in the forearm under general anesthesia, normal saline was injected at a speed of approximately 1 mL/s while the axillary artery and vein were observed with color flow Doppler imaging. The volume of normal saline required to induce a change in the color flow pattern around the vessels was measured. Measurements were performed twice and averaged for comparison with patient characteristics and other factors.

RESULTS

The study cohort included 30 patients aged from 0.3 to 5.5 (2.6 ± 1.6) years. The change in color flow Doppler imaging was noted in all the patients, and the average volume was 1.40 ± 0.36 mL (95% confidence interval (CI), 1.27-1.54; p < 0.001), which was significantly correlated with age, with a correlation coefficient of 0.435 (95% CI, 0.09-0.69; p = 0.02).

CONCLUSIONS

The required volume for the color flow injection test is small; therefore, the test is easy to perform and minimally invasive in pediatric patients.

Influential factors on the echogenicity of peripheral venous catheters: Insights from an experimental phantom study

INTRODUCTION

Ultrasound-guided placement of peripheral venous catheters requires appropriate equipment. Among the devices used, peripheral venous catheters have different structure and properties. This study aimed to define the impact of these different factors on the echogenicity of peripheral venous catheters.

METHOD

An open comparative study was conducted from September 2022 to May 2023. Thirteen devices were introduced in a standardized manner along the longitudinal and transverse axes with the help of guides into a phantom at different angles. Two criteria defined the echogenicity of these devices: the surface occupied by the device in the image (composite criterion: length and diameter of the device and angle of insertion) and its brightness (average of the pixel intensity of gray). Sixty-five ultrasound images were recorded and postprocessed twice (blinded to the previous measurement) by an expert operator, for reproducibility purposes.

RESULTS

The intra-observer reproducibility of all measurements was excellent, with an intra-class coefficient of >0.90 over the entire dataset. On the longitudinal axis, echogenicity was significantly influenced by insertion angle (p = 0.009), device length (p = 0.006), and the interaction of cannula component and insertion angle (p = 0.007). On the transverse axis, no factors significantly influenced the device's echogenicity.

DISCUSSION

The echogenicity of a device is an essential component of successful ultrasound-guided peripheral venous catheter placement. Optimizing catheter intrinsic factors such as components of the cannula and length, and extrinsic factor like the insertion angle should be considered in their design and use to reduce puncture failure rates.

Long peripheral catheters for intravenous infusions of iloprost or alprostadil therapy in rheumatologic outpatients

BACKGROUND

Long peripheral catheters (LPCs) role in Difficult IntraVenous Access (DIVA) patients admitted to the emergency department has already been studied, resulting in a rapid, safe, and cost-effective procedure. Although their use in outpatient settings is established, there is a lack of studies assessing their benefits. In particular, rheumatologic outpatients affected by scleroderma, especially those affected by digital ulcers, are often treated with intravenous infusions of prostaglandin I2 (PGI2) analog (IV-PGI2A).

OBJECTIVE AND METHODS

From 1 October 2021 to 31 March 2024, we conducted a prospective study enrolling DIVA outpatients affected by systemic sclerosis or undifferentiated connective tissue disease who needed IV-PGI2A therapy at L. Sacco Hospital in Milan (Italy). Each treatment cycle consisted of four consecutive days of infusion of iloprost or alprostadil. The primary aim was to assess the efficacy and potential complications associated with LPCs for IV-PGI2A.

RESULTS

Twenty-six patients were enrolled 23 were females (88.5%), and the median age was 72 years (IQR 56-78.7). In total, 97 LPCs were inserted, with a mean number of insertions per patient/year of 2.3. An increase in LPCs insertion during the 30 months of the enrollment period was observed. Eighteen patients required more than one LPC placement, and in 61% of them, the second venipuncture was executed at a different site. No procedural complications were registered (accidental puncture of the brachial artery, accidental median nerve puncture, bleeding) nor late complications (Catheter-Related Thrombosis, Catheter-Related Bloodstream Infections, Accidental Removal).

CONCLUSIONS

Our experience shows that LPCs could be valuable and safe for rheumatologic outpatients. The increased number of insertions and new and total patients enrolled each year defines the satisfaction of patients and health care professionals.

Poland's first vascular access team 3-year analysis: Insights and learnings

BACKGROUND

During the COVID-19 pandemic, Poland saw a surge in interest in midline catheters (MCs) and Long Peripheral Catheters (LPCs) for intravenous therapy. Before this, MCs were not extensively utilised in the country, and there was no formally established Polish vascular access team. MCs, which have been used for years in many countries, are now becoming increasingly common in Poland. This study aimed to analyse the use of MCs in a 3-year perspective of their introduction in daily clinical practice based on a nurse-led Vascular Access Team (VAT).

METHODS

The records of adult patients who received intravenous therapy with 727 MCs and 293 LPCs from January 2021 to December 2023 at the University Clinical Centre of the Medical University of Warsaw were analysed.

RESULTS

The main indication for cannulation was expected intravenous therapy over 5 days (81.66%, n = 833), of which 71.37% (n = 728) of patients in this group had concomitant difficult intravenous access (DIVA). Over 6 years, centrally inserted central catheters (CICCs) inserted due to DIVA were reduced from n = 108 in 2017 to n = 18 in 2023. The end of intravenous therapy was the reason for the removal of 64.6% of catheters (n = 659), including death and switch to CICCs as well. Complications leading to premature removal accounted for 31.2%, such as: occlusion (14.6%), patient self-removal (7.1%) and thrombosis (3.43%).

CONCLUSIONS

The introduction of MCs as a possible option for peripheral venous access reduces the use of CVCs. Developing MCs programmes should be based on investing in staff competencies, which increases success rates. The nurses and physicians should be trained in infusion care to achieve better results in the use of MCs and LPCs. Increasing the competence of nurses in Poland is necessary for the implementation of full-service and top-level functioning of VAT.

Catheter detection by transthoracic echocardiography during placement of peripherally inserted central catheters: a real-time method for eliminating misplacement

BACKGROUND

Although guidelines and protocols are available for central venous access, existing methods lack specificity and sensitivity, especially when placing peripherally inserted central catheters (PICCs). We evaluated the feasibility of catheter detection in the right atrial cavity using transthoracic echocardiography (TTE) during PICC placement.

METHODS

This single-center, retrospective study included consecutive patients who underwent PICC placement between January 2022 and March 2023. TTE was performed to detect the arrival of the catheter in the right atrial cavity. Catheter misplacement was defined as an aberrant catheter position on chest x-ray (CXR). The primary endpoint was predicting catheter misplacement based on catheter detection in the right atrial cavity. The secondary endpoint was optimizing catheter placement and examining catheter-associated complications.

RESULTS

Of the 110 patients identified, 10 were excluded because of poor echogenicity and vein access failure. The remaining 100 patients underwent PICC placement with TTE. The catheter was visualized in the right atrial cavity in 90 patients. CXR exams revealed catheter misplacement in seven cases. Eight patients with catheter misplacement underwent the same procedure in the other arm. In two patients, PICC placement failed due to anatomical reasons. Catheter misplacement was detected using TTE with sensitivity, specificity, positive predictive value, and negative predictive value of 97% confidence interval (CI; 91.31%-99.36%), 90% CI (55.50%-99.75%), 99%, and 75%, respectively.

CONCLUSIONS

TTE is a reliable tool for detecting catheter misplacement and optimizing catheter tip positioning during PICC placement.

Transverse incision versus longitudinal incision in the implantation of PICC-port: A before-after study

BACKGROUND

The peripherally inserted central catheter-port (PICC-port) technique is an innovation of the standard arm-totally implantable vascular access device. The design of surgical skin incision may have an important impact on the postoperative life of patients, the cosmetic result is important for patient satisfaction as well.

OBJECTIVES

To compare two different incision methods in the implantation of PICC-port.

DESIGN

A before-after study.

SETTINGS AND PARTICIPANTS

A total of 62 adult patients with malignant tumor requiring chemotherapy in Shanghai General Hospital were selected by convenience sampling, 31 in each group. All participants agreed to install PICC-port with signature from 1 Jan to 30 April, 2022.

METHODS

31 patients were given longitudinal incision, about 3 cm below the puncture point obliquely. Another 31 patients were given transverse incision, about 3 cm below the puncture point. T-test, chi-square test and rank sum test were used to compare the differences between the two groups in incision healing, scar score, and operation time.

RESULTS

There was no statistically significant difference in incision healing between the two groups(p > 0.05). The scar scores of patients with transverse incision were higher than that of patients with longitudinal incision at 3 months (p < 0.05). And the operation time of longitudinal incision group was longer than that of transverse incision group(p < 0.05).

CONCLUSIONS

Our study revealed that PICC-port implantation could be considered as safe as PICC insertion conducted by nurse. During our follow-up, all patients with PICC-port implantation had good wound healing, and there were no complications such as local infection happened. The transverse incision was more easier to be operated in bag making in PICC-port implantation.

Should ultrasound evaluation for catheter-related thrombosis always be required before PICC removal?

Despite several effective preventive strategies peripherally inserted central catheters (PICCs)-as much as centrally inserted central catheters and femorally inserted central catheters-are inevitably associated with the potential development of catheter-related thrombosis. This complication may be symptomatic or-more often-asymptomatic. Even if remote, the chance that PICC removal may mobilize an asymptomatic thrombus and cause pulmonary embolism, is theoretically possible. On the other hand, the diffuse adoption of an ultrasound scan aiming at detecting an asymptomatic catheter-related thrombosis may be logistically difficult and expensive. No clear evidence-based recommendations exist on this issue and whether perform an ultrasound scan before PICC removal in asymptomatic patients remains a matter of debate. For these reasons, the authors propose few common sense recommendations that may help clinicians in weighing the clinical advantages of the exam (optimal safety for the patient) versus its practical disadvantages (logistic cost).

Femorally inserted central catheters with exit site at mid-thigh: A low risk alternative for central venous catheterization

BACKGROUND

Femorally inserted central catheters are increasingly used, especially after the COVID-19 pandemic, also thanks to widespread of tunneling techniques that allow the exit site to be moved away from the groin.

METHODS

In this retrospective observational study, femorally inserted catheters, with exit site at mid-thigh and the tip in Inferior vena cava or in Inferior vena cava at the junction with right atrium, have been observed and complications have been analyzed. All catheters were inserted by trained Nurses of a tertiary hospital Vascular Access Team.

RESULTS

In 142 catheters (126 inserted via common femoral vein and 16 inserted via superficial femoral vein) and 3060 catheter days, we observed an infection rate of 1.3 events/1000 catheter days (all of them in oncologic patients and up to 30 days of catheterization), 2 cases of thrombotic events (1.41%) and 17 cases of accidental removal (11.97%). Other rare complications, as primary malposition, tip migration, arterial pseudoaneurysm, have been recorded. The average length of catheters inserted, from the exit site to the tip, was 47.6 ± 2.4 cm.

CONCLUSION

The attention to the correct position of the tip, the exit site at mid-thigh and the new techniques during insertion make these femoral catheters as safe as other central vascular access devices. For this kind of central access device, a catheter at least 50 cm long is needed.

Ultrasound versus intracavitary electrocardiography for intraprocedural tip location during central venous catheterization in infants and children: A prospective clinical study

BACKGROUND

Both intracavitary electrocardiography (IC-ECG) and ultrasound (US) have been proven to be safe and accurate for intraprocedural tip location during central venous catheterization, and both are known to be easily applicable and feasible in pediatric patients. Though, no prospective clinical study has directly compared the two methods as regards their applicability, feasibility, and procedural time.

METHODS

This study prospectively enrolled all children requiring a central venous access device in non-emergency situations, during a period of 1 year. All devices were inserted according to a well-defined insertion bundle including both IC-ECG and US-based tip location. The primary endpoint of the study was to compare the two methods in terms of applicability, feasibility and time required.

RESULTS

This study included 100 consecutive central venous catheterizations in children of age ranging from 1 month to 18 years. The applicability of IC-ECG based tip location was 98% and its feasibility 100%; the time required for IC-ECG was 1.9 ± 2 min. The applicability of US-based tip location was 96% and its feasibility was 100%; the maneuver required 2.2 ± 3 min.

CONCLUSIONS

US is an appropriate alternative method for intraprocedural tip location in children. The combined use of US and IC-ECG (both maneuvers being accurate, inexpensive, cost-effective, non-invasive, and equally fast to perform) should be recommended for tip location in pediatric patients, and it will avoid completely the use of fluoroscopy or of post-procedural x-ray.

The First Use of a Midline Catheter in Outpatient Pain Management

Midline catheters (MCs) are used to deliver intravenous therapy lasting over 5 days to patients in hospitals. However, the constant development of home and outpatient care is challenging medical teams to provide effective and safe planned therapy to patients under such conditions. We describe the first time an MC was used in outpatient pain management in Poland. A 60-year-old man presented to the Pain Management Clinic with a history of RCC of the left kidney and lumbar back pain radiating to the left knee joint. The person whose case is described below had poor peripheral veins. He intravenously received lidocaine for 10 days via a midline catheter with a good response.

Color changing bioadhesive barrier for peripherally inserted central catheters

Bacteria migration at catheter insertion sites presents a serious complication (bacteraemia) with high mortality rates. One strategy to mediate bacteraemia is a physical barrier at the skin-catheter interface. Herein a colorimetric biosensor adhesive (CathoGlu) is designed and evaluated for both colorimetric detection of bacterial infection and application as a bacteria barrier. The design intent combines viscous, hydrophobic bioadhesive with an organic pH indicator (bromothymol blue). Visual observation can then distinguish healthy skin at pH = ∼5 from an infected catheter insertion site at pH = ∼8. The liquid-to-biorubber transition of CathoGlu formulation occurs via a brief exposure to UVA penlight, providing an elastic barrier to the skin flora. Leachates from CathoGlu demonstrate no genotoxic and skin sensitization effect, assessed by OECD-recommended in vitro and in chemico assays. The CathoGlu formulation was found non-inferior against clinically approved 2-octyl-cyanoacrylate (Dermabond™), and adhesive tape (Micropore™) within an in vivo porcine model. CathoGlu skin adhesive provides new opportunities to prevent sepsis in challenging clinical situations.

A new pressure-based device for tip navigation and tip location during central venous catheterization: A prospective clinical study on a cohort of 136 adult patients

INTRODUCTION

According to current guidelines, tip location of peripherally inserted central catheters (PICCs) should be verified during insertion, preferably using non-invasive methods such as intracavitary ECG (IC-ECG) or echocardiography. An interesting new option is represented by a new pressure-based device, the CatFinder System (CFS), which might be theoretically useful also for tip navigation.

METHODS

We planned a single-center, prospective, non-randomized trial on adult patients requiring PICC insertion, using simultaneously CFS and IC-ECG, with the purpose of verifying the applicability, feasibility, safety, and accuracy of CFS for intra-procedural tip location. Patients with known ECG abnormalities or cardiac diseases of any type were excluded. The ability of CFS to assess wrong directions of the catheter during insertion (tip navigation) was evaluated by comparison with ultrasound scan.

RESULTS

Out of 136 enrolled adult patients, CFS was found to be applicable in 131 cases (five cases were excluded because of ECG abnormalities) and feasible in 111 cases (in 20 cases, tip location by CFS could not be carried out because of technical issues). There were no complications directly or indirectly related to the CFS maneuvers. Using IC-ECG as a comparison, 87 tips placed by CFS were within 2 cm from the target, 17 were >2 cm from target. In seven cases, CFS was able to detect a wrong direction (to the ipsilateral internal jugular vein), as confirmed by ultrasound.

CONCLUSION

Applicability of CFS in patients with sinus rhythm was 96.3%, feasibility was 84.7%, and safety was 100%. If compared to IC-ECG, accuracy was 83.6% (accepting an error <2 cm) and 96.1% (for an error <3 cm). Unacceptable tip positions (>3 cm) were 3.8% (the tip was too high inside the SVC). This study confirms a possible future role of CFS for intra-procedural tip location and tip navigation, though its use cannot be currently recommended.

Point-of-care ultrasound for vascular access in neonates and children

Ultrasound plays a major role in neonatal/pediatric vascular access, both for venous access and for arterial access, not only just for the insertion of intravascular catheters, but also for many other issues related to this type of maneuver. This "global use of ultrasound" includes a systematic and consistent adoption of this technology for several steps of vascular access: (a) the pre-procedural assessment/evaluation of the vessels, (b) the ultrasound-guided puncture and cannulation of arteries and veins, (c) the real-time diagnosis of immediate, puncture-related complications, (d) the so-called "tip navigation" (i.e., real-time intra-procedural assessment of the direction and trajectory of the guidewire and/or of the catheter inside the vasculature), (e) the so-called "tip location" (i.e., intra-procedural or post-procedural assessment of the proper position of the tip of the catheter), and (f) the early diagnosis and/or management of most non-infective late complications.

CONCLUSION

Therefore, any vascular access expert (nurse or physicians) should have documented competency in the use of ultrasound. This knowledge should include the use of ultrasound for assessment of vessels, for catheter insertion, for proper placement of the tip, and for real-time detection of complications.

WHAT IS KNOWN

• Ultrasound is obviously useful for vascular access procedures in neonates and children.

WHAT IS NEW

• Recent evidence suggests that ultrasound is useful for many purposes in the field of vascular access (preprocedural scan, ultrasound-guided puncture, tip navigation, tip location, diagnosis of most non-infective complications). • Recent evidence also suggests that radiological methods no longer play any role in the insertion of vascular accesses in neonates and children.

Brachial Tunneled Peripherally Inserted Central Catheters and the Risk of Catheter Complications: A Systematic Review and Meta-Analysis

INTRODUCTION

Situations involving increased workloads and stress (i.e., the COVID-19 pandemic) underline the need for healthcare professionals to minimize patient complications. In the field of vascular access, tunneling techniques are a possible solution. This systematic review and meta-analysis aimed to compare the effectiveness of tunneled Peripherally Inserted Central Catheters (tPICCs) to conventional Peripherally Inserted Central Catheters (cPICCs) in terms of bleeding, overall success, procedural time, and late complications.

METHODS

Randomized controlled trials without language restrictions were searched using PUBMED®, EMBASE®, EBSCO®, CINAHL®, and the Cochrane Controlled Clinical Trials Register from August 2022 to August 2023. Five relevant papers (1238 patients) were included.

RESULTS

There were no significant differences in overall success and nerve or artery injuries between the two groups (p = 0.62 and p = 0.62, respectively), although cPICCs caused slightly less bleeding (0.23 mL) and had shorter procedural times (2.95 min). On the other hand, tPICCs had a significantly reduced risk of overall complications (p < 0.001; RR0.41 [0.31-0.54] CI 95%), catheter-related thrombosis (p < 0.001; RR0.35 [0.20-0.59] IC 95%), infection-triggering catheter removal (p < 0.001; RR0.33 [0.18-0.61] IC 95%), wound oozing (p < 0.001; RR0.49 [0.37-0.64] IC 95%), and dislodgement (p < 0.001; RR0.4 [0.31-0.54] CI 95%).

CONCLUSIONS

The tunneling technique for brachial access appears to be safe concerning intra-procedural bleeding, overall success, and procedural time, and it is effective in reducing the risk of late complications associated with catheterization.
