Assessment of infants with peripherally inserted central catheters: Part 1. Detecting the most frequently occurring complications

Association between heparin addition to parenteral nutrition and catheter-related complications in very preterm infants: A retrospective cohort study

BACKGROUND

This study aimed to assess the necessity of adding heparin to parenteral nutrition for continuous infusion through a peripherally inserted central catheter in very preterm infants.

METHODS

This retrospective cohort study was conducted between January 1, 2019, and January 1, 2023. Preterm infants with gestational age <32 weeks requiring a peripherally inserted central catheter for parenteral nutrition were included. The heparin group received parenteral nutrition with 0.5 IU/ml heparin added for infusion through a peripherally inserted central catheter, whereas the nonheparin group did not receive heparin. Propensity score matching was used to balance baseline variables between the two groups. The primary outcome was the incidence of catheter-related complications. A noninferiority margin of 10% was chosen. Nonelective catheter removal, heparin-related side effects, and catheter dwell time were compared between the two groups.

RESULTS

A total of 1089 very preterm infants were included. After propensity score matching, 432 infants from each group were analyzed. The incidence of catheter-related complications was 22.9% in the heparin group and 21.8% in the nonheparin group, with an absolute difference of -1.16% (95% CI: -6.71% to 4.40%). The upper bound was below 10% (P for noninferiority < 0.001), confirming noninferiority. In addition, no significant difference was found between the two groups in the incidence of nonelective catheter removal or heparin-related side effects.

CONCLUSION

Parenteral nutrition without heparin was noninferior to the addition of heparin during infusion through peripherally inserted central catheter on the risk of catheter-related complications in very preterm infants.

Effect of adding heparin to parenteral nutrition on catheter intraluminal obstruction based on scanning electron microscopy in preterm neonates: A non-inferiority, randomized controlled trial

OBJECTIVES

This study aimed to assess the need for adding heparin to parenteral nutrition (PN) on reducing catheter intraluminal obstruction based on scanning electron microscopy (SEM) of peripherally inserted central catheter (PICC) in preterm neonates.

METHODS

In this randomized controlled blinded non-inferiority trial, neonates with gestational age <32 weeks requiring PICC to receive PN were enrolled and randomly divided into two groups. In the heparin group, 0.5 IU/mL heparin was added to PN for continuous infusion through PICC; while in the no-heparin group, there was no heparin added. All catheter tips were collected for SEM of catheter intraluminal obstruction. The primary outcome was the ratio of intraluminal obstructed area at catheter tip calculated by SEM. A non-inferiority margin of 0.1 was chosen. The duration of catheter patency, incidence of catheter-related complications, and heparin-related side effects were analyzed.

RESULTS

Between June 1, 2021, and May 31, 2022, 91 neonates (gestational age of 28.17 ± 1.77 weeks) were ultimately enrolled. In the intention-to-treat analysis, the average ratio of intraluminal obstructed area at catheter tip indicated by SEM in no-heparin group was 0.313, and 0.362 in the heparin group (95% confidence intervals of the differences was -0.028 to 0.147). The lower bound of the one-side 95% confidence intervals was greater than -0.1, indicating non-inferiority. No statistically significant differences existed in the duration of catheter patency, the incidence of catheter-related complications between two groups.

CONCLUSIONS

PN without heparin was non-inferior to the addition of 0.5 IU/mL heparin to PN during infusion on reducing catheter intraluminal obstruction based on SEM of PICC in preterm neonates. These findings could reduce the unnecessary exposure to heparin in preterm neonates.

Octyl-butyl-cyanoacrylate glue for securement of peripheral intravenous catheters: A retrospective, observational study in the neonatal population

BACKGROUND

Evidence-based insertion and maintenance strategies for neonatal vascular access devices (VAD) exist to reduce the causes of VAD failure and complications in neonates. Peripheral intravenous catheter failure and complications including, infiltration, extravasation, phlebitis, dislodgement with/without removal, and infection are majorly influenced by catheter securement methods.

METHODS

A retrospective, observational study using routinely collected data on intravenous device use in a large neonatal intensive care unit in Qatar. A 6-month historical cohort was compared with a 6-month cohort after the introduction of an octyl-butyl-cyanoacrylate glue (CG). In the historical cohort, the catheter was secured using a semi-permeable transparent membrane dressing while in the CG cohort, CG was applied at the insertion site on initial insertion and after any dressing change. This was the only variable intervention between both groups.

RESULTS

A total of 8330 peripheral catheters were inserted. All catheters were inserted and monitored by members of the NeoVAT team. 4457 (53.5%) were secured with just a semi-permeable transparent dressing and 3873 (46.5%) secured a semi-permeable transparent dressing with the addition of CG. The odds ratio for premature failure after securement with CG was 0.59 (0.54-0.65) when compared to the catheters secured with a semi-permeable transparent dressing, which was statistically significant (p < 0.001). The correlation between the occurrence of a complication and the use of CG for device securement was significant (p < 0.001).

CONCLUSIONS

The risk of developing device-related phlebitis and premature device removal, increased significantly if CG was not used for adjunct catheter securement. In parallel with the currently published literature, this study's findings support the use of CG for vascular device securement. When device securement and stabilization concerns are most pertinent CG is a safe and effective adjunct to reducing therapy failures in the neonatal patient population.

Physicochemical compatibility of caffeine citrate and caffeine base injections with parenteral medications used in neonatal intensive care settings

PURPOSE

To investigate the physicochemical compatibility of caffeine citrate and caffeine base injections with 43 secondary intravenous (IV) drugs used in Neonatal Intensive Care Unit (NICU) settings.

METHODS

Caffeine citrate (20 mg/mL or 10 mg/mL) or caffeine base injection (10 mg/mL) were mixed in a volume ratio of 1:1 with the secondary drug solution to simulate Y-site co-administration procedures in NICUs. Physical compatibility was evaluated based on visual observation for 2 h, against a black and white background and under polarised light, for changes in colour, precipitation, haze and evolution of gas. Chemical compatibility was determined from caffeine concentration measurements, using a validated high-performance liquid chromatography assay.

RESULTS

Six of the 43 secondary drugs tested (aciclovir, amphotericin (liposomal), furosemide, hydrocortisone, ibuprofen and ibuprofen lysine) were physically incompatible with caffeine citrate undiluted injection (20 mg/mL), at their high-end, clinically relevant concentrations for NICU settings. However, when tested at lower concentrations, hydrocortisone (1 mg/mL) was physicochemically compatible, whereas furosemide (0.2 mg/mL) was physically incompatible with caffeine citrate. The six drugs which showed physical incompatibility with caffeine citrate 20 mg/mL injection were also physically incompatible with caffeine citrate 10 mg/mL solution. All 43 secondary drugs tested were physicochemically compatible with caffeine base injection.

CONCLUSIONS

Most secondary test drugs, except aciclovir, amphotericin (liposomal), furosemide, hydrocortisone, ibuprofen and ibuprofen lysine, were physicochemically compatible with caffeine citrate injection. Caffeine base injection was physicochemically compatible with all 43 test drugs tested.

Comparing conventional and modified Seldinger techniques using a micro-insertion kit for PICC placement in neonates: a retrospective cohort study

Objective

This study aims to assess the comparative effectiveness of a conventional splitting needle or a peelable cannula vs. the modified Seldinger technique (MST) by utilizing a dedicated micro-insertion kit across various clinically significant metrics, including insertion success, complications, and catheter-related infections.

Methods

We conducted a retrospective observational cohort study using an anonymized data set spanning 3 years (2017-2019) in a large tertiary-level neonatal intensive care unit in Qatar.

Results

A total of 1,445 peripherally inserted central catheter (PICC) insertion procedures were included in the analysis, of which 1,285 (89%) were successful. The primary indication for insertion was mainly determined by the planned therapy duration, with the saphenous vein being the most frequently selected blood vessel. The patients exposed to MST were generally younger (7 ± 15 days vs. 11 ± 26 days), but exhibited similar mean weights and gestational ages. Although not statistically significant, the MST demonstrated slightly higher overall and first-attempt insertion success rates compared to conventional methods (91 vs. 88%). However, patients undergoing conventional insertion techniques experienced a greater incidence of catheter-related complications (p < 0.001). There were 39 cases of catheter-related bloodstream infections (CLABSI) in the conventional group (3.45/1,000 catheter days) and eight cases in the MST group (1.06/1,000 catheter days), indicating a statistically significant difference (p < 0.001). Throughout the study period, there was a noticeable shift toward the utilization of the MST kit for PICC insertions.

Conclusion

The study underscores the viability of MST facilitated by an all-in-one micro kit for neonatal PICC insertion. Utilized by adept and trained inserters, this approach is associated with improved first-attempt success rates, decreased catheter-related complications, and fewer incidences of CLABSI. However, while these findings are promising, it is imperative to recognize potential confounding factors. Therefore, additional prospective multicenter studies are recommended to substantiate these results and ascertain the comprehensive benefits of employing the all-in-one kit.

Real-Time Ultrasound Tip Location Reduces Malposition and Radiation Exposure during Epicutaneo-Caval Catheter Placement in Neonates

OBJECTIVE

Epicutaneo-caval catheters (ECCs) are essential for the care of sick infants who require long-term medical and nutritional management. The aim of this study was to investigate the use of real-time ultrasound as an alternative to X-rays to reduce the incidence of primary malpositions during catheter insertion.

STUDY DESIGN

Data on ECCs were retrospectively collected in a tertiary neonatal intensive care unit. Catheter were analyzed considering the tip location technique (standard chest-abdominal radiograph vs real-time ultrasound) RESULTS:  A total of 248 ECCs were analyzed. Of these, 118 catheters had primary malposition (47.6%). The tip of 165 catheters was assessed using standard chest-abdominal X-rays and 107 (64.8%) were found to be in an inappropriate location. In the group of 83 catheters that were placed using real-time ultrasound for tip location, only 11 catheters (13.2%) had primary malposition. The rate of malposition among the two groups showed a statistically significant difference (p < 0.001). Hypothetically, 300 chest X-rays could have been saved if real-time ultrasound had been used to locate the tip, reducing radiation exposure to infants.

CONCLUSION

The use of a real-time ultrasound may be beneficial in reducing primary catheter malpositions compared with conventional radiography. In addition, secondary malpositions and catheter-related complications can be monitored over time.

KEY POINTS

· Conventional radiology cannot be considered the "gold standard" for ECC tip location.. · Ultrasound is more accurate and reduces insertion time reducing the rate of primary malposition.. · Ultrasound can be performed in real time and it is the best technique for ECC tip location in infants..

Venous Access: National Guideline and Registry Development (VANGUARD): Advancing Patient-Centered Venous Access Care Through the Development of a National Coordinated Registry Network

There are over 8 million central venous access devices inserted each year, many in patients with chronic conditions who rely on central access for life-preserving therapies. Central venous access device-related complications can be life-threatening and add tens of billions of dollars to health care costs, while their incidence is most likely grossly mis- or underreported by medical institutions. In this communication, we review the challenges that impair retention, exchange, and analysis of data necessary for a meaningful understanding of critical events and outcomes in this clinical domain. The difficulty is not only with data extraction and harmonization from electronic health records, national surveillance systems, or other health information repositories where data might be stored. The problem is that reliable and appropriate data are not recorded, or falsely recorded, at least in part because policy, payment, penalties, proprietary concerns, and workflow burdens discourage completeness and accuracy. We provide a roadmap for the development of health care information systems and infrastructure that address these challenges, framed within the context of research studies that build a framework of standardized terminology, decision support, data capture, and information exchange necessary for the task. This roadmap is embedded in a broader Coordinated Registry Network Learning Community, and facilitated by the Medical Device Epidemiology Network, a Public-Private Partnership sponsored by the US Food and Drug Administration, with the scope of advancing methods, national and international infrastructure, and partnerships needed for the evaluation of medical devices throughout their total life cycle.

Performance of tunnelled, non-cuffed central venous catheters in infants: A scoping review

AIM

To summarise and critique existing knowledge and evidence relating to the utility, and post-insertion complications surrounding tunnelled non-cuffed central venous catheters (tncCVCs) in infants.

METHODS

A scoping review of original research studies reporting the use of, and post-insertion complications associated with, tncCVCs in infants was completed. MeSH terms were used to formulate a systematic search, and data were extracted using a customised data extraction form. Data were analysed descriptively across key themes based on the research questions. Study quality was evaluated using the Mixed Methods Appraisal Tool.

RESULTS

The systematic search generated 3994 studies, of which 9 studies met final inclusion criteria. Studies included 644 tncCVCs in infants based in the USA, Europe and Australia. Most studies were retrospective cohort studies. The most common vein of insertion, where individually specified, was the internal jugular (n = 177). Tunnel length, where reported, was 2.5-5 cm. Infection rates were most commonly reported (eight studies), with results ranging from 0 to 12.8%, and device dislodgements of up to 20% reported. Participant follow-up and definition of complications varied greatly between studies. Study quality across all papers was sound.

CONCLUSIONS

This review has identified only a small number of studies, with small participant numbers, reporting the performance of tncCVCs in infants. Definitions of complications measured varied significantly between studies, and vastly different patient follow-up protocols were reported. Further larger-scale studies on the performance of tncCVC, employing internationally recognised reporting standards is warranted to ensure clinicians can make informed choices for medication and infusion delivery.

Unveiling Peripherally Inserted Central Catheter Fractures and Related Complications in the Neonatal Intensive Care Unit: A Concise Review

Peripherally inserted central catheters (PICCs) have become popular over tunneled catheters in neonatal intensive care units (NICUs) due to their ease of use and convenience. Although rare, a PICC fracture can be a severe and potentially fatal complication. This narrative review aims to identify factors predisposing neonates to PICC fracture and related complications, such as catheter jamming, and explore strategies for preventing and detecting this complication. A thorough search of PubMed and Google Scholar was conducted using relevant keywords to identify articles discussing PICC fracture in neonates. The review encompassed English-language literature on PICC fracture in neonates, with additional pertinent publications identified through citation searching. The incidence of PICC fracture in neonates varies from less than 1% to 10%, with a higher risk associated with prolonged catheterization, lower gestational age and lower birth weight, and the use of multi-lumen catheters. PICC fractures can occur during insertion, maintenance, or removal. Factors such as catheter duration, gestational age, birth weight, and catheter type increase the risk of PICC fracture. Excessive syringe pressure, securement failure, and excessive force during removal are contributing factors. Catheter fatigue and thin-walled catheter design are common causes of breakage. Preventive measures include proper training of healthcare providers, regular monitoring, early recognition, and prompt catheter removal upon fracture. Preventing and detecting PICC fractures is crucial for neonatal safety. Vigilance during insertion, maintenance, and removal, along with care to avoid excessive force during removal and high pressure during flushing, can help prevent catheter breakage. More research is required to improve prevention strategies for PICC fractures in neonates.

Role of a radiopaque agent and surveillance radiographs for peripherally inserted central catheters in newborn infants

BACKGROUND

Controversy exists regarding the use of a radiopaque agent to identify peripherally inserted central catheter (PICC) tip positions in newborn infants and of serial radiography to monitor PICC tip migration.

OBJECTIVE

To investigate the roles of (1) the injection of a radiopaque agent to identify PICC tip position and (2) the performance of weekly radiography to monitor PICC migration.

MATERIALS AND METHODS

This retrospective single-centre cohort study included newborn infants who received a PICC between 1 January 2016 and 31 December 2020. A radiopaque agent was injected to identify PICC tip position and radiographs were performed weekly to detect PICC migration.

RESULTS

We identified 676 PICC episodes in 601 infants. A radiopaque agent was used for 590 of these episodes. There was no difference in the proportion of central PICC tip positions based on radiopaque agent use status (490/590, 83% for the radiopaque agent used group versus 73/85, 85.8% for the radiopaque agent not used group, P=0.51). Irrespective of the site of PICC insertion, outward migration was observed for most centrally placed PICCs over their entire in situ duration. Inward migration was identified in 23 out of 643 PICC episodes (3.6%) only on radiographs obtained on or before day 7. Based on serial radiographs, the odds for PICC tips remaining in a central position were lower the longer the PICC remained in situ (adjusted odds ratio-OR 0.93; 95% confidence interval 0.92-0.95). There was no difference in PICC migration between side and limb of insertion.

CONCLUSION

PICC tips can be identified without injection of a radiopaque agent. Serial radiographs identified PICC migration over the in situ duration. This study has implications for reducing exposure to a radiopaque agent and ongoing migration surveillance practices.

A nurse-inserted peripherally inserted central catheter program in general pediatrics: a single-center experience

BACKGROUND

A peripherally inserted central catheter (PICC) with its tip preferably in the vena cava is essential in caring for patients with chronic conditions in general pediatrics. However, PICC-related complications are concerning and warrant further investigations.

OBJECTIVES

To share the experience of a nurse-inserted peripherally inserted central catheters (PICC) program initiated in a general pediatric department.

METHODS

A retrospective descriptive cohort study based on a prospectively collected database was conducted. All PICCs inserted in the departments of gastroenterology and pulmonology in a tertiary pediatric center from Dec. 2015 to Dec. 2019 were included in the study. Complications and risk factors were analyzed by comparing cases with and without complications. We also reported arm movements in correcting mal-positioned newly-inserted PICCs.

RESULTS

There were 169 cases with a median (IQR) age of 42(6, 108) months who received PICC insertion during a 4-year period. Inflammatory bowel disease was the leading diagnosis accounting for 25.4% (43/169) of all cases. The overall complication rate was 16.4 per 1000 catheter days with malposition and occlusion as the two most common complications. Multivariate models performed by logistic regression demonstrated that young age [p = 0.004, OR (95%CI) = 0.987(0.978, 0.996)] and small PICC diameter (1.9Fr, p = 0.003, OR (95%CI) = 3.936(1.578, 9.818)] were risk factors for PICC complications. Correction of malpositioned catheters was attempted and all succeeded in 9 eligible cases by using arm movements.

CONCLUSION

The nurse-inserted PICC program in general pediatrics is feasible with a low rate of complications. PICC tip malposition and occlusion were two major PICC-related complications when low age and small catheter lumina were major risk factors. Furtherly, arm manipulation potentially is an easy and effective approach for correcting malpositioned newly-inserted PICC catheters.

Effects of Early versus Standard Central Line Removal on the Growth of Preterm Infants with Very Low Birth Weight: A Non-Inferiority, Randomized Clinical Trial

Very preterm infants are usually supported by parenteral nutrition delivered through central lines (CLs) while progressing with enteral intake, although the optimal time point for their removal is unclear. This study evaluated the impact of the CL discontinuation time on the short-term growth outcomes of preterm infants. A non-inferiority, parallel-group, randomized controlled trial was conducted in four neonatal intensive care units in Poland. Preterm infants with very low birth weight (VLBW) without congenital abnormalities were eligible. Patients were allocated to discontinue central access at an enteral feeding volume of 100 mL/kg/day (intervention group) or 140 mL/kg/day (control group). The study's primary outcome was weight at 36 weeks' postmenstrual age, with a non-inferiority margin of -210 g. Overall, 211 patients were allocated to the intervention or control groups between January 2019 and February 2021, of which 101 and 100 were eligible for intention-to-treat analysis, respectively. The mean weight was 2232 g and 2200 g at 36 weeks' postmenstrual age in the intervention and control groups, respectively. The mean between-group difference was 32 g (95% confidence interval, -68 to 132; p = 0.531), which did not cross the specified margin of non-inferiority. No intervention-related adverse events were observed. Early CL removal was non-inferior to the standard type for short-term growth outcomes in VLBW infants.

Mechanical complications of weekly care and maintenance versus once every 10 days of the peripherally inserted central catheter line insertion site in newborns: A propensity score-matched cohort study in Mexico

PURPOSE

To evaluate the mechanical complications of weekly care and maintenance versus once every 10 days of the peripherally inserted central catheter (PICC) line insertion site versus once every 10 days in newborns.

DESIGN AND METHODS

Prospective propensity score matched cohort study. Care and maintenance of the PICC line insertion site were performed on days 7 and 10 during January 2018 to December 2019. To compare mechanical complications, propensity score matching was performed. Propensity scores were used to determine the relative risks and hazard ratios by using logistic regressions with log-link function and Cox regressions, respectively.

RESULTS

We included 175 newborns hospitalized in the neonatal intensive care unit (NICU) who underwent insertion of a PICC line. Ninety-six received weekly care and maintenance, and 79 received care and maintenance every 10 days. Weekly care and maintenance were associated with more breakage (RR 1.98, 95% CI 1.68-2.34); occlusions (RR 0.81, 95% CI 0.46-1.42) and accidental withdrawals (RR 1.31, 95% CI 0.93-1.84) were not different between care and maintenance every 7 and 10 days. A survival analysis was performed, showing that weekly care and maintenance are a risk factor for removal for mechanical complications (HR 7.61, 95% CI 3.05-19.01).

CONCLUSION

We concluded that care and maintenance of the PICC in newborns every 10 days have fewer complications than when performing care and maintenance every 7 days.

PRACTICE IMPLICATIONS

Newborns requiring intravenous therapy will benefit from care and maintenance every 10 days, and this practice could potentially spread to other NICUs.

Cyanoacrylate Securement in Neonatal PICC Use: A 4-Year Observational Study

BACKGROUND

Within every neonatal clinical setting, vascular access devices are considered essential for administration of fluids, nutrition, and medications. However, use of vascular access devices is not without danger of failure. Catheter securement adhesives are being evaluated among adult populations, but to date, studies in neonatal settings are scant.

PURPOSE

This research describes the prevalence of peripherally inserted central catheter failure related to catheter securement before and after the introduction of tissue adhesive for catheter securement. The identified modifiable risks might be used to evaluate efficacy, to innovate neonatal practice and support future policy developments.

METHOD AND SETTING

This was a retrospective observational analysis of routinely collected anonymized intravenous therapy-related data. The study was carried out at the tertiary neonatal intensive care unit (112 beds) of the Women's Wellness and Research Center of Hamad Medical Corporation, Doha, Qatar.

RESULTS

The results showed that the use of an approved medical grade adhesive for catheter securement resulted in significantly less therapy failures, compared with the control group. This remains significant after adjusting for day of insertion, gestational age, birth weight, and catheter type.

IMPLICATIONS FOR PRACTICE AND RESEARCH

In parallel with currently published international literature, this study's findings support catheter securement with an octyl-based tissue adhesive in use with central venous catheters. When device stabilization is most pertinent, securement with tissue adhesive is a safe and effective method for long-term vascular access among the neonatal population.

Evaluation of a diluted lipid emulsion solution as a lubricant for improved peripherally inserted central catheter guidewire removal in a neonatal population

BACKGROUND

Medical management of neonates is often established upon safe and reliable vascular access, frequently utilized to provide physiological monitoring, parenteral and supportive treatments, and diagnostic and/or procedural purposes. For this, peripherally inserted central catheters (PICCs) are often used to provide safe vascular access and infusion-related therapies in the neonatal intensive care (NICU) setting.

PURPOSE

Difficult PICC guidewire removal is understood to cause catheter damage, causing luminal rupture or possible breakage of the catheter or guidewire itself. The aim of this study was to assess and compare the incidence of therapy failures with use of a preflush fluid using normal saline (NSS) versus a diluted lipid solution (DLS) prior to device insertion, to assist with guidewire removal and prevent unnecessary catheter damage.

METHOD AND SETTING

A retrospective, observational study was performed in the Neonatal Intensive Care Unit (NICU) of the Women's Wellness and Research Centre, Hamad Medical Corporation, Qatar. This single site study included 507 neonates who required intravenous therapy administered via a PICC during the study period.

RESULTS

Results demonstrated the use of a diluted lipid solution preflush (DLS) resulted in significantly lesser failures, when compared with the control group (NSS). This highlights a clinical significance after adjusting for day of insertion, gestational age, birth weight and catheter type.

CONCLUSION

DLS preflush demonstrated a benefit over the use of a NSS preflush to enhance PICC guidewire removal in neonatal patients in the NICU. The risk for development of maintenance-related complications leading to premature device removal decreased significantly if the DLS preflush was used. During the study period, no complications related to the use of a lipid preflush solution were identified.

IMPLICATIONS FOR PRACTICE AND RESEARCH

This may be the first study published investigating and supporting guidewire removal enhancement by using a diluted lipid/saline preflush solution. When the requirement for vascular access is most pertinent in the neonate, using a diluted lipid preflush may provide an effective method to assist in guidewire removal to prevent malposition and vascular device complications in the neonatal population.

Charakteristika und klinische Manifestation katheterassoziierter Thrombosen bei Frühgeborenen

Hintergrund

In der Neonatologie sind peripher eingeführte zentrale Katheter ein häufiger Zugangsweg zur parenteralen Ernährung und Verabreichung von Medikamenten und Flüssigkeit. Die Vorteile stehen den Risiken wie Infektion, Thrombose und Fehllage gegenüber.

Fragestellung

Welche Charakteristika und klinischen Zeichen weisen auf das Vorliegen einer katheterassoziierten Thrombose hin?

Material und Methoden

In einer retrospektiven Betrachung aus dem Zeitraum 2010–2016 wurden alle Fälle von katheterassoziierten Thrombosen untersucht. Identifiziert wurden 10 Frühgeborene, deren Indikation zur Katheteranlage, Zugangsweg, Lage der Katheterspitze, Liegedauer, klinische Symptome und Krankheitsverlauf analysiert wurden.

Ergebnisse

Bei 10 Frühgeborenen mit einem Gestationsalter von 23 + 4 bis 34 + 5 SSW wurden 11 Thromboseereignisse beobachtet. Zehn der 11 Thromboseereignisse betrafen die V. cava inferior nach Katheteranlage an der unteren Extremität. Die Indikation zur Katheteranlage waren parenterale Ernährung und chirurgische Eingriffe. Bei 9 Patienten traten perinatale Komplikationen auf. Bei allen Patienten bestand während der Liegedauer der Katheter der Verdacht auf eine Infektion. Das Auftreten der Thrombose wurde nach 3 bis 27 Tagen sonographisch dokumentiert. In 8 Thromboseereignissen war eine Thrombozytopenie, in 4 Fällen eine Beinschwellung auffällig.

Diskussion

Das Patientenkollektiv zeigt Gemeinsamkeiten im klinischen Verlauf und bei den Symptomen, welche auf das Vorliegen einer Thrombose deuten. Auffällig ist außerdem, dass die meisten Thromboseereignisse das Stromgebiet der V. cava inferior betrafen.

Clinical usefulness of catheter-drawn blood samples and catheter-tip cultures for the diagnosis of catheter-related bloodstream infections in neonates

Catheter-drawn blood sampling is an efficient method of diagnosing catheter-related bloodstream infection (CRBSI) in neonates; it has greater sensitivity and accuracy than methods using catheter-tip cultures. No association was detected between catheter-drawn blood sampling and the occurrence of adverse events with central venous catheters.

Epicutaneo-caval catheters in neonates: New insights and new suggestions from the recent literature

Epicutaneo-caval catheters have been widely used in neonatal intensive care units since Shaw has described them in 1973. These central venous access devices are usually placed at bedside and they have the purpose of delivering parenteral nutrition and/or drugs that are not compatible with the peripheral route. Even though in the last decade there was a fast advancement in the world of vascular access devices, such changes have only marginally affected the field of neonatal venous access. The aim of this editorial is to give 10 recommendations that correspond to 10 novelties in the field of epicutaneo-caval catheter: some are already evidence-based and should be introduced in our daily practice now, while others are particularly interesting and deserve further clinical studies.

Feasibility and Outcomes Associated With the Use of 2.6-Fr Double-Lumen PICCs in Neonates

BACKGROUND

Low birth-weight infants' survival continues to improve and there is increased need to provide secure vascular access. This study examines safety of larger peripherally inserted central catheters (PICCs) that offer greater utility.

PURPOSE

To determine feasibility of 2.6-French (Fr) double-lumen PICCs in newborns and compare noninfectious complications such as thrombus formation, catheter breakage, infiltration, and accidental dislodgment and central line-associated bloodstream infection (CLABSI) rate with that of newborn infants treated with 1.9-Fr single- and double-lumen PICCs.

METHODS

Infants requiring PICCs were admitted in our 69-bed level IV neonatal intensive care unit from September 2006 to May 2015. Two distinct groups were compared: the 1.9-Fr-(single-lumen [n = 105] and double-lumen [n = 27])-and 2.6-Fr double-lumen PICCs (n = 111). Data obtained included birth weight and weight at insertion, gestational age at birth and corrected gestation age at insertion, indication, catheter days, indication for removal, and complications: noninfectious and infectious. Univariate and multivariate statistical analysis evaluated data.

RESULTS

There were no differences regarding gestational age at birth and insertion and indications for placement of 2.6-Fr double-lumen (n =111) and 1.9-Fr both single- and double-lumen (n = 132) PICCs. The same was noted between the groups' complications. Noninfectious complications were more common in PICCs with peripheral tip location in all groups.

IMPLICATIONS FOR PRACTICE

Consider use of 2.6-Fr PICCs in a neonatal intensive care unit when the utility of blood administration and sampling is required.

IMPLICATIONS FOR RESEARCH

Examine line migration and CLABSI associated with sampling and blood administration.

Perforations associated with peripherally inserted central catheters in a neonatal population

BACKGROUND

Peripherally inserted central catheters (PICCs) are increasingly used in neonates but perforations can result in devastating complications such as pericardial and pleural effusions. Identifying risk factors may guide surveillance and reduce morbidity and mortality.

OBJECTIVE

To determine the risk factors for PICC perforation in neonates.

MATERIALS AND METHODS

Retrospective case:control (1:2) study of neonates admitted between 2004-2014. Charts and imaging were reviewed for clinical and therapeutic risk factors.

RESULTS

Among 3,454 PICCs, 15 cases of perforation (incidence 0.4%, 5 pericardial effusions, 10 pleural effusions) were matched to 30 controls, based on gestation and insertion date. Timing of perforations post-insertion was median 4 days for pericardial effusions and 21.5 days for pleural effusions. A risk factor for pericardial effusion was lower weight at PICC insertion compared with controls. There were no statistically significant differences between cases and controls in catheter material, insertion site, PICC size and lumen number. Among upper limb PICCs, pericardial effusions were associated with tip positions more proximal to the heart at insertion (P=0.005) and at perforation (P=0.008), compared with controls. Pleural effusions were associated with tip positions more distal from the heart at perforation (P=0.008). Within 48 h before perforation, high/medium risk infusions included total parenteral nutrition (100% cases vs. 56.7% controls, P=0.002) and vancomycin (60% cases vs. 23.3% controls, P=0.02).

CONCLUSION

PICC-associated pericardial effusions and pleural effusions are rare but inherent risks and can occur at any time after insertion. Risk factors and etiologies are multifactorial, but PICC tip position may be a modifiable risk factor. To mitigate this risk, we have developed and disseminated guidelines for target PICC positions and routinely do radiographs to monitor PICCs for migration and malposition in our NICU. The increased knowledge of risk profiles from this study has helped focus surveillance efforts and facilitate early recognition and treatment.

Peripheral venous catheter complications in children: predisposing factors in a multicenter prospective cohort study

Background

Peripheral venous catheterization (PVC) is frequently used in children. This procedure is not free from potential complications. Our purpose was to identify the types and incidences of PVC complications in children and their predisposing factors in a developing country.

Methods

We conducted a prospective observational multicenter study in five pediatric and pediatric surgery departments over a period of 2 months. Two hundred fifteen PVC procedures were conducted in 98 children. The times of insertion and removal and the reasons for termination were noted, and the lifespan was calculated. Descriptive data were expressed as percentages, means, standard deviations, medians and interquartile ranges. The Chi2 test or the Fisher test, with hazard ratios and 95% confidence intervals (CI_95%), as well as Student’s t test or the Mann-Whitney U test were used to compare categorical and quantitative variables, respectively, in groups with and without complications. The Spearman test was used to determine correlations between the lifespan and the quantitative variables. The Kruskal Wallis test was used to test for differences in the median lifespan within 3 or more subgroups of a variable. Linear regression and logistic binary regression were used for multivariate analysis. A p-value <0.05 was considered significant.

Results

The mean lifespan was 68.82 ± 35.71 h. A local complication occurred in 111 PIVC (51.9%) cases. The risk factors identified were a small catheter gauge (24-gauge) (p = 0.023), the use of a volume-controlled burette (p = 0.036), a longer duration of intravenous therapy (p < 0.001), a medical diagnosis of respiratory or infectious disease (p = 0.047), the use of antibiotics (p = 0.005), including cefotaxime (p = 0.024) and vancomycin (p = 0.031), and the use of proton pump inhibitors (p = 0.004).The lifespan of the catheters was reduced with the occurrence of a complication (p < 0.001), including the use of 24-gauge catheters (p = 0.001), the use of an electronic pump or syringe(p = 0.036) and a higher rank of the intravenous device in each patient (p = 0.010).

Conclusions

PVC complications were frequent in our pediatric departments and are often associated with misuse of the device. These results could engender awareness among both doctors and nurses regarding the need for rationalization of the use of PVC and better adherence to the recommendations for the use of each drug and each administration method.

Peripheral intravenous cannulation: complication rates in the neonatal population: a multicenter observational study

INTRODUCTION

Neonates admitted to a neonatal intensive care unit (NICU) rely highly on intravenous (IV) therapy, for which the peripheral intravenous cannula (PIVC) is the preferred device to allow such therapies to proceed. Placement of a PIVC is a painful procedure and repeated attempts for successful insertion should therefore be limited. We aimed to quantify the incidence, complications, and factors associated with these complications.

METHODS

We conducted a prospective observational study to examine PIVC-related complications in level III NICUs of two university medical centers (UMC) in The Netherlands. We performed descriptive analyses and binary logistic regression analysis to identify factors associated with PIVC complications.

RESULTS

A total of 518 catheters were inserted in 235 infants. The first-time success rate was 45%. The predominant reason for non-elective removal due to complications was infiltration (N = 193; 67%). No significant association was found between discipline of the inserter, vein visualization device and location of the PIVC and whether or not a catheter needed to be removed due to a complication.

CONCLUSIONS

In this study the majority of PIVCs were removed after the occurrence of a complication. The most common complication was infiltration. Strategies to identify and prevent infiltration in an NICU population are required. Future interventional studies should attempt to improve first-time insertion success and reduce PIVC failure from infiltration in the neonate. Based on the results of the present study, neonatologists and physician assistants are the preferential PIVC inserters. Advanced training of all members of vascular access specialist teams and ongoing monitoring of PIVC-related complications are recommended.

Thrombosis in the Neonatal Intensive Care Unit

Neonates have the highest risk for pathologic thrombosis among pediatric patients. A combination of genetic and acquired risk factors significantly contributes to this risk, with the most important risk factor being the use of central venous catheters. Proper imaging is critical for confirming the diagnosis. Despite a significant number of these events being life- and limb-threatening, there is limited evidence on what the appropriate management strategy should be. Evaluation and treatment of any neonate with a clinically significant thrombosis should occur at a tertiary referral center that has proper support.

Complication risks associated with lower versus upper extremity peripherally inserted central venous catheters in neonates with gastroschisis

PURPOSE

To compare the complication rates of lower extremity (LE) and upper extremity (UE) peripherally inserted central catheters (PICCs) in neonates with gastroschisis.

METHODS

In this retrospective comparative study, neonates with gastroschisis admitted to a level IIId NICU between 2004 and 2013 were identified. Catheter dwell time and complication rates (infiltration, phlebitis, occlusion, migration, infection and thrombosis) between the initial UE and LE PICCs were compared.

RESULTS

Forty (31%) and eighty-nine (69%) neonates with gastroschisis had their initial PICCs placed from their LE and UE, respectively. Complication rates were significantly higher when PICCs were inserted from LE, especially during silo-reduction and within 5 days after abdominal closure (LE: 20% vs. UE: 3.4%, p<0.01). LE PICCs were 5.0 times more likely to have complications than UE PICCs (OR 95% CI: 1.2-21.5) during this time period. In particular LE PICCs had significantly higher rates of infiltration (LE: 11.5% vs. UE: 1.4%; p=0.025) and phlebitis (LE: 11.5% vs. UE: 0%; p<0.01) in patients who underwent silo-reduction.

CONCLUSION

LE PICCs are associated with significantly increased risks of infiltration and phlebitis in neonates with gastroschisis during silo-reduction and within 5 days after abdominal closure.

Patient- and Device-Specific Risk Factors for Peripherally Inserted Central Venous Catheter—Related Bloodstream Infections

Objective.

To determine the patient- and device-specific risk factors for hospital-acquired peripherally inserted central venous catheter–related bloodstream infections (PICC BSIs) in adult patients.

Design.

Nested case-control study.

Setting.

Barnes-Jewish Hospital, a 1,252-bed tertiary care teaching hospital.

Patients.

Adult patients with PICCs placed from January 1, 2006, through July 31, 2008.

Methods.

PICC BSI cases were identified using the National Healthcare Safety Network definition. Uninfected control patients with PICCs in place were randomly selected at a 3: 1 ratio. Patient- and device-related variables were examined using multivariate analysis.

Results.

The overall PICC BSI rate was 3.13 per 1,000 catheter-days. Independent risk factors for PICC BSIs included congestive heart failure (odds ratio [OR], 2.0 [95% confidence interval (CI), 1.26–3.17];P= .003), intra-abdominal perforation (OR, 5.66 [95% CI, 1.76–18.19];P= .004),Clostidium difficileinfection (OR, 2.25 [95% CI, 1.17–4.33];P= .02), recent chemotherapy (OR, 3.36 [95% CI, 1.15–9.78];P= .03), presence of tracheostomy (OR, 5.88 [95% CI, 2.99–11.55];P< .001), and type of catheter (OR for double lumen, 1.89 [95% CI, 1.15–3.10];P= .01; OR for triple lumen, 2.87 [95% CI, 1.39–5.92];P= .004). Underlying chronic obstructive pulmonary disease (OR, 0.48 [95% CI, 0.29–0.78];P= .03) and admission to surgical (OR, 0.43 [95% CI, 0.24–0.79];P= .006) or oncology and orthopedic (OR, 0.35 [95% CI, 0.13–0.99];P= .05) services were less likely to be associated with having a PICC BSI.

Conclusions.

We identified several novel factors related to PICC BSIs. These factors may inform preventive measures.

[Reasons for non-elective removal of epicutaneous catheters in neonates]

This study aimed to describe the incidence and reasons for nonelective removal of epicutaneous catheters in neonates, identifying its association with the catheter insertion site. This was a prospective cohort study, conducted in a neonatal intensive care unit of a private tertiary hospital in the city of São Paulo, Brazil. We analyzed 266 epicutaneous catheter insertions. The incidence of non-elective removal was 39.1%. The most frequent post-insertion complications were suspicion of catheter-related bloodstream infection (25%) and rupture (23.1%). Most catheters were inserted through the right side of the body (65%), in upper limbs (77.1%), and using the axillary veins (31.2%). The findings did not suggest association between the incidence of non-elective removal and the insertion site of the epicutaneous catheter in neonates. Nurses should implement strategies to improve care and decrease incidence of non-elective epicutaneous catheter removals among neonates.

Evaluation of neonatal peripherally inserted central catheter tip movement in a consistent upper extremity position

OBJECTIVE

To compare the effect of standardized upper extremity position versus varied upper extremity positions on neonatal peripherally inserted central catheter (PICC) tip placement and movement. Secondary outcomes assessed were compliance with education, implementation, and complication rates.

STUDY DESIGN

Tip movement was analyzed between 136 post-PICC insertion x-ray pairs from 72 infants in the 6 months before and after standardization of upper extremity position. Tip movement was regressed over days between x-ray pairs, respiratory support, absolute weight change, and insertion vein.

RESULTS

There was no difference in PICC tip movement among varied analysis pairs or when standard position pairs were compared with pairs that were in a same nonstandard position. Days between x-rays, respiratory support, absolute weight change, and insertion vein did not predict tip movement. Attendance at education sessions was 100%. Compliance with the new standard was 73%. Complication rates were not significantly different.

CONCLUSION

Standardization of upper extremity position during neonatal PICC confirmation x-rays did not alter PICC tip movement.

Peripherally inserted central catheters: use at a tertiary care pediatric center

PURPOSE

To examine the use of peripherally inserted central catheters (PICCs) in a tertiary care pediatric setting.

MATERIALS AND METHODS

An observational study of use and referral practices for PICCs in a tertiary care pediatric setting was performed with three distinct approaches: (i) in an institutional overview of trends, data from 2001 to 2012 were initially analyzed to identify high-level trends; (ii) an in-depth analysis of PICC referrals during 1 year was performed to determine details of referral patterns and clinical practices; and (iii) an electronic survey of the perception and understanding of referring clinical staff was conducted.

RESULTS

During the past decade, there has been a steady increase in the number of PICC insertions and a decrease in median PICC dwell times. Discrepancies were identified between the anticipated versus actual dwell times. A large proportion of patients was found to have multiple PICC insertions, short dwell times, and premature PICC removals, potentially resulting in increasing risks of short- and long-term complications. Large percentages of the staff respondents valued the role of PICCs and had a good understanding of short-term complications, but underestimated the scale of the PICC service (numbers placed, resources involved) and several long-term complications associated with PICCs.

CONCLUSIONS

The number of PICCs inserted in children is increasing while PICC dwell times are decreasing. Better postprocedure care is important to minimize premature removals and avoid repeat insertions. Associated complications are not fully appreciated by the referring pediatricians. Further education and guidelines are needed.

Echocardiography allows more accurate placement of peripherally inserted central catheters in low birthweight infants

AIM

The use of plain radiographs provides limited information on the placement of peripherally inserted central catheters (PICCs). Moreover, changes in upper extremity positioning cause migration of the catheters in neonates. This study aimed to investigate the use of echocardiography for determining catheter tip position, compared with plain radiographs, in low birthweight (LBW) infants in a tertiary neonatal intensive care unit.

METHODS

The study examined the placement of 109 catheters in 89 infants born between September 2010 and December 2012. The placement of these catheters was controlled by echocardiography, with the patient's shoulder in adduction and the elbow in flexion. The number of catheter tips, echocardiographically identified within the heart, was expressed as a percentage of the total catheters deemed to be well positioned on plain radiographs.

RESULTS

The number of catheter tips that were echocardiographically identified within the heart was significant (25%, p < 0.001). Twenty-three catheters were repositioned to be outside of the heart, without any complications.

CONCLUSION

This study demonstrated the value of echocardiography for identifying the positioning of catheter tips in LBW infants. Echocardiography, coupled with initial plain radiographs, should be the gold standard for assessing PICC tip positions in those infants.

Peripherally inserted central catheter complications in neonates with upper versus lower extremity insertion sites

PURPOSE

To compare peripherally inserted central catheter (PICC) complication rates in upper versus lower extremity insertion sites in neonates.

SUBJECTS

Neonates who had PICCs inserted while hospitalized in an urban, 84-bed, level III neonatal intensive care unit in the southwestern United States between 2004 and 2009 were included in the study. A total of 559 neonates with 626 PICCs were reviewed. Neonates who were transferred out of the hospital with an indwelling PICC or had incomplete PICC data were excluded (n = 29).

DESIGN

Comparative descriptive.

METHOD

Retrospective review of PICC records. Demographic data, neonate survival to PICC removal, PICCs inserted by non-PICC team members, and complications were compiled. Complications included presumed sepsis, occlusion, leaking, infiltration/edema, inadvertent removal, phlebitis, pleural effusion, tip malposition, and catheter breakage. The complications were analyzed between extremities using chi-square or independent-samples t test where appropriate.

MAIN OUTCOME MEASURES

Type and rate of complication requiring PICC removal and the extremity used for insertion.

PRINCIPAL RESULTS

A total of 374 PICCs (59.7%) were inserted in upper extremities and 252 (40.3%) in lower extremities. The upper and lower extremity groups were comparable in all variables except neonate survival to PICC removal, which was greater in neonates with lower extremity PICCs (95.2% in upper extremities vs 98.8% in lower extremities; P = .01). No significant difference (P = .08) was found in the overall complication rate (27% in upper extremity PICCs vs 21% in lower extremity PICCs). Presumed sepsis was the most common complication requiring PICC removal in both extremity groups. At the time of removal, upper extremity PICCs were more likely to have a noncentral tip than lower extremity PICCs (15% vs 4%, respectively). In PICCs removed because of complications, noncentral tips were found to be statistically significant in upper extremity PICCs (P < .0001).

CONCLUSIONS

No significant difference was found in complications that necessitated PICC removal between upper versus lower extremity PICC insertion sites. Catheter tip location may have a significant impact on complications and deserves further investigation. The choice of a PICC insertion site in neonates should be based on the quality of appropriate, available veins and the preference and skill of the inserter. Every effort should be made to achieve and maintain a centrally located PICC tip.

Complications of peripherally inserted central venous catheter in Japanese neonatal intensive care units

BACKGROUND

The aim of this study was to investigate the incidence and risk factors of peripherally inserted central venous catheter (PICC)-related complications using a multicenter case survey.

METHOD

A prospective cohort study was carried out by 19 neonatal intensive care units (NICUs) in Japan from February 2005 to March 2007. A total of 975 case records were collected. PICC-related complications including pericardial effusion/cardiac tamponade pleural effusion/ascites, catheter removal difficulties, catheter-related bloodstream infection (CR-BSI), and symptomatic catheter-related thrombosis were collected from case record forms. As for precautions during insertion, institutions were classified into three groups: those with maximum barrier precautions; standard precautions; and no specific precautions.

RESULTS

PICC complications occurred in 27 cases (2.9%) among 946 PICC. The incidence was 1.6% for CR-BSI, and 0.1% for cardiac tamponade. CR-BSI rate per 1000 catheter-days was 1.1 with maximum barrier precautions at catheter insertion, 1.2 with standard precautions, and 1.8 with no specific precautions. Multiple logistic regression analysis showed that proximal placement (odds ratio [OR], 3.88; 95% confidence interval [CI]: 1.42-10.60, P = 0.008) and longer placement duration (OR, 1.35; 95%CI: 1.14-1.60, for each week, P = 0.0005) independently contributed to overall complications.

CONCLUSION

The incidence of cardiac tamponade was rare in this multicenter prospective study. Longer duration and proximal placement may be risk factors for PICC complications. In this cohort, the CR-BSI rate was low irrespective of the degree of barrier precautions at insertion.

Peripherally inserted central catheter tip position and risk of associated complications in neonates

OBJECTIVE

To characterize the relationship between peripherally inserted central catheters (PICC) tip positions and associated complications in neonates.

STUDY DESIGN

Catheter tip position for 319 infants was classified into superior vena cava (SVC, n=131), inferior vena cava (IVC, n=72), brachiocephalic (BC, n=59), midclavicular (MC, n=49) or iliac. Duration of catheter stay and complication profile was compared between central (SVC/IVC) vs non-central PICC, and between SVC vs IVC, SVC vs BC and SVC vs MC. Kaplan-Meier survival analysis and regression models were used.

RESULT

Overall length of catheter stay was similar between central and non-central group. Non-central catheters (n=116) had higher complication rates (47 vs 29%; P=0.001), non-elective removals (45 vs 27%; P=0.002) and shorter time to complication (6.2 vs 11.4 days; P=0.043). This difference was primarily due to the complications encountered in MC group, which had the highest rate of infiltration (P<0.001) and mechanical complications while outcomes were similar among other subgroups. Interestingly, catheter survival probability was similar in all groups for first 4 days. Rate and types of blood stream infections were not related to catheter tip position.

CONCLUSION

Non-central PICCs are associated with higher rates of infiltration and mechanical complications when the tip is in MC region. BC catheters may have comparable outcomes to SVC in neonates. A careful risk-benefit analysis is warranted when MC catheters are used in neonates.

Parental influence on clinical management during neonatal intensive care: a survey of US neonatologists

OBJECTIVE

Family-centered care (FCC), which includes involving parents in conversations about medical management, is increasingly employed in the neonatal intensive care unit (NICU). Our aim was to determine which care decisions are discussed by neonatologists with families most frequently and the percentage of clinicians influenced by such conversations.

METHODS

Anonymous web-based survey provided to 2137 neonatologists assessing information sharing and parental involvement.

RESULTS

Thousand and two neonatologists responded in which 893 fully completed the surveys. 88% practice FCC. Topics most frequently discussed with parents were blood transfusion, steroids for lung disease and patent ductus arteriosus (PDA) surgery, each being reported and discussed by more than 90% of respondents. Many therapies, including aminoglycoisdes, total parenteral nutrition, and phototherapy, were discussed with parents by far fewer clinicians. Additionally, parents had most influence on clinicians in two categories, blood transfusion and steroids, with more than 70% reporting that their practice was influenced by parental opinion if communicated. For some topics, such as PDA surgery and central line placement, conversations impacted few clinicians.

CONCLUSIONS

FCC appears to have an impact on NICU clinical decision-making processes, some more than others. Further investigation in this area may provide information on how to best communicate with families and run effective, efficient FCC rounds.

Complications associated with central and non-central venous catheters in a neonatal intensive care unit

OBJECTIVE

The objective of this study is to compare complication rates between peripherally inserted central catheters (PICCs) and peripherally inserted non-central catheters (PINCCs) in the neonatal intensive care unit (NICU).

STUDY DESIGN

A retrospective, observational study was conducted. The PICCs were catheters whose tip terminated in the vena cavae, and PINCCs were defined as those whose tip fell short of this location. Complication rates were assessed using generalized estimating equations modeling.

RESULT

A total of 91 PINCCs and 889 PICCs were placed in 750 neonates. In all, 44.0% of PINCCs had a major complication compared with 25.2% of PICCs (P=0.0001). The unadjusted (unadj.) complication rate among PINCCs was 51.7 per 1000 line days and 15.9 for PICCs (unadj. rate ratio: 3.25; 95% confidence interval (CI): 2.32, 4.55). After adjusting for multiple confounders, the risk remained significantly higher for PINCCs (adjusted odds ratio: 2.41; 95% CI: 1.33, 4.37).

CONCLUSION

The rate of associated complications with the use of PINCCs in the NICU population is more than twice that of the PICCs.

Guide-wire fragment embolisation in paediatric peripherally inserted central catheters

OBJECTIVE

To report guide-wire fragment embolisation of paediatric peripherally inserted central catheter (PICC) devices and explore the safety profile of four commonly used devices.

DESIGN, SETTING AND PARTICIPANTS

Clinical incidents involving paediatric PICC devices in Queensland public hospitals were reviewed. A PICC user-experience survey was conducted at five public hospitals with 32 clinicians. A device design evaluation was undertaken, and magnetic resonance imaging (MRI) safety was tested by a simulation study.

MAIN OUTCOME MEASURES

Embolisation events; technical mistakes, multiple attempts and breakages during insertion; willingness to use the device; failure modes and risk priority rating; movement and/or temperature change on exposure to MRI.

RESULTS

Six clinical incidents of silent guide-wire embolisation, and four near misses were identified; all were associated with one type of device. The survey found that this device had a reported broken-wire embolisation rate of 0.9/100 insertions with no events in other devices; two of the four devices had a higher all-cause embolisation rate (3.3/100 insertions v 0.4/100 insertions) and lower clinician acceptance (68%-71% v 91%-100%). All devices had 6-17 identified failure modes; the two devices that allowed removal of a guide wire through a septum had the highest overall risk rating. Guide-wire exposure to MRI was rated a potential safety risk due to movement.

CONCLUSIONS

There is marked variation in the safety profile of 3 Fr PICC devices in clinical use, and safety performance can be linked to design factors. Pre-MRI screening of all children who have previously had a PICC device inserted is recommended. We advocate a decision-making model for evaluation of device safety.

The Effects of Focused Nursing Education on 3F Groshong™ PICC Occlusion Rates: The Experience of One Tertiary Pediatric Care Facility

OBJECTIVE: The primary aim of this project is to reduce the incidence of 3 Fr. Groshong™ PICC occlusions through focused nursing education. BACKGROUND: The use of Peripherally Inserted Central Catheters (PICC) has become an essential tool in the care of pediatric patients. The small lumen and long length of PICCs requires specialized skill and knowledge in proper care, maintenance and flushing in order to prevent catheter occlusion and other complications. Occluded catheters compromise patient care and increase costs. Reducing the incidence of catheter occlusion, will have a significant impact on the quality of patient care; patient, family and nursing satisfaction, patient outcomes, and costs. METHODS: A pre-test/post-test design using a convenience sample of all the core staff nurses working on the medical/surgical unit at a Southern California Children's Hospital was utilized. Objective measures included a written assessment of nursing knowledge, direct observations of nurses' flushing technique, and retrospective chart review to determine the rate of total catheter occlusion. RESULTS: Mean written test scores improved from 0.78 to 0.93 (p=0.00) Mean observation scores improved from 0.88 to 0.95, (p=0.004). The pre-test occlusion rate was 21.11/1000 catheter days. The post test occlusion rate was 15.49/1000 catheter days (p=0.057). CONCLUSION: Focused nursing education contributed to reducing 3F Groshong™ PICC occlusions and the associated costs due to PICC occlusions.

Securing pediatric peripheral i.v. catheters--application of an evidence-based practice model

Peripheral intravenous catheter (PIV) insertion is a traumatic experience for children and should not be repeated more frequently than necessary. Proper securement of pediatric i.v.s can preserve catheter life; however, little evidence is available to describe optimal methods. Pediatric nurses at a 246-bed, community-owned district hospital observed they were frequently attempting to rescue or restart PIVs prematurely. In the context of exemplary professional practice, an exploratory evidence-based practice project was designed to increase knowledge about the best practices in maintaining and preserving pediatric PIVs. Data collection and analysis determined that practices were inconsistent and more research is needed to determine the optimal securement practices.

Neonatal PICC: one unit's six-year experience with limiting catheter complications

Safe dressing techniques for neonatal peripherally inserted central catheters (PICCs) remain controversial in the literature. This article describes one unit's experience with the placement and management of 491 PICCs during a six-year period with more than 5,600 catheter days. The dressing technique described in this article differs from that seen in the literature with the addition of a protective base layer. Catheter complication rates are low, and catheter dressing changes are minimized with this dressing technique.

Repositioning techniques for malpositioned neonatal peripherally inserted central catheters

The utilization of Peripherally Inserted Central Catheters (PICCs) has grown to become a common practice in neonatal care. Proper placement of the catheter in the superior vena cava (SVC) is essential to support safe delivery of care and minimize complications. This article describes three cases of patients whose catheters were malpositioned on initial placement or while in situ, that were successfully guided to appropriate tip location in the superior vena cava by implementing a combination of non-invasive catheter repositioning techniques.

Are supine chest and abdominal radiographs the best way to confirm PICC placement in neonates?

BACKGROUND

Peripherally inserted central catheters (PICCs) are commonly used in NICUs. Although they have many benefits, they also have many potential complications. Confirming catheter tip position is essential to decreasing complications, but the best method to achieve confirmation is unclear.

OBJECTIVES

Literature review for studies that address line position confirmation to assist health care providers in evaluating the available research and to identify gaps in the literature.

METHOD

A literature search of four major databases followed by an ancestry approach was performed. Articles reviewed specifically discuss PICC lines and PICC line placement confirmation.

RESULTS

Data on confirming PICC placement were lacking. Fluoroscopic placement is ideal, but cannot be done at the bedside and is costly. Supine chest radiograph is the most widely used method and is convenient, but when line tip position is unclear, contrast or ultrasound confirmation can be used. When PICC lines are placed in the saphenous vein, infants may benefit from supine and lateral abdominal radiographs to ensure placement in the inferior vena cava.

DISCUSSION

More studies are needed to generalize findings. PICC line tips should be located in the superior vena cava or inferior vena cava close to the junction with the right atrium (0.5-1 cm outside of the cardiac chambers in premature infants and 1-2 cm outside of the cardiac chambers in larger infants). Arm position is very important when performing radiographs for placement because movement of the arm can cause migration of the catheter. There is also significant inter-observer variability when identifying line tip position.

Minimizing catheter-related bloodstream infections: one unit's approach

Catheter-related bloodstream infection (CRBSI) is the most common complication related to peripherally inserted central catheters in the neonatal intensive care unit. CRBSIs are responsible for many morbidities and mortalities occurring in special care nurseries. However, these vascular access devices are an essential aspect of neonatal care and therefore are indispensable. To minimize CRBSI incidences and improve patient outcomes, objectives must be established to focus on the prevention of these potentially life-threatening infections. This article identifies the interventions incorporated by our facility to prevent nosocomial bloodstream infections.

Neonatal peripherally inserted central catheters: recommendations for prevention of insertion and postinsertion complications

Peripherally inserted central catheters (PICCs) continue to be necessary in neonatal care. They benefit many premature infants and those needing long-term intravenous access. An experienced inserter, early recognition of PICC candidates, early PICC placement, knowledge of anatomy, and correct choice of vein all increase placement success. As with any invasive procedure, there are risks. These include pain, difficulty advancing the catheter, damage to vessels, catheter malposition, and bleeding. Utilizing assessment skills, following the product manufacturer's instructions, and carefully placing the catheter should minimize most of these risks. Additional risks include postinsertion complications such as occlusions, thrombosis, catheter failure, infection, and catheter malposition. Proper nursing care--which includes controlling infection, properly securing the catheter, and changing the dressing as needed--is key to preventing complications and maintaining the PICC until treatment has been completed.

Tiny patients, tiny dressings: a guide to the neonatal PICC dressing change

Advances in neonatology now support the survival of the tiniest of infants. The peripherally inserted central catheter (PICC) has now become an integral part of routine practice in neonatal intensive care units around the world. Keen attention to safe maintenance of these devices is essential. A properly applied and maintained PICC dressing is the first line of defense to minimize the risk of complications such as dislodgement, migration, and infection. This article describes a neonatal PICC dressing change and discusses the frequently encountered quandaries surrounding this important procedure, including dressing materials, frequency, site preparation, barrier precautions, and other relevant concerns.
