Chest-to-arm tunneling technique for central venous access devices in neonates

BACKGROUND

Chest-to-arm (CTA) tunneling technique has been described recently as an alternative option to exit site of the catheter in the infraclavicular area.

METHOD

We report our experience with ultrasound-guided centrally inserted central catheters (CICCs) placed using CTA tunneling in six neonates. All central venous catheters were positioned with ultrasound guidance and real-time tip location.

RESULTS

There were no insertion-related complications; all devices were correctly positioned at the first attempt. During the follow-up, we found no catheter-related thrombosis, infections, or catheter malfunction. No tip position-related complications. Only one case of secondary malposition was reported.

CONCLUSION

In our experience, the CTA tunneling technique is reliable, safe, and feasible in the neonate even from the first hours of life, as well as for preterm newborns; it could be a valid alternative to the usual exit site.

Prospective case series study on the use of a novel analgosedation protocol for ultrasound-guided catheterization in Neonatal Intensive Care Unit

Critically ill newborns admitted to Neonatal Intensive Care Unit often require a centrally inserted central catheters (CICCs) inserted by ultrasound-guided puncture of the internal jugular or brachio-cephalic vein. Achieving an appropriate level of sedation and analgesia is paramount for procedure success and patient safety, avoiding the potential risks associated with excessive deep sedation. The aim of this study is to evaluate the feasibility of a novel protocol of sedation. Data from 46 patients were prospectively collected. The feasibility was assessed throughout the monitoring of adverse events and the incidence of spontaneous movements. The procedure was completed in 100% of cases. There were no cases of escalation of the baseline ventilatory support despite the procedure and no case of hypotension, and all spontaneous movements were controlled with additional boluses when required.

CONCLUSION

Our study represents the very first step towards the design of a validated protocol for analgosedation during ultrasound-guided CICC insertion in NICU.

WHAT IS KNOWN

• Critically ill newborns admitted to Neonatal Intensive Care Unit often require a centrally inserted central catheter. • Achieving an appropriate level of sedation and analgesia is paramount for procedure success and patient safety, avoiding the potential risks associated with excessive deep sedation.

WHAT IS NEW

• The use of this new protocol for analgosedation is able to achieve a good level of sedation and pain control without significant adverse event. • Ultrasound-guided CICC insertion can be performed even in non-ventilated newborns.

Ultrasound-Guided Centrally Inserted Central Catheter (CICC) Placement in Newborns: A Safe Clinical Training Program in a Neonatal Intensive Care Unit

BACKGROUND

Centrally inserted central catheters (CICCs) are increasingly used in neonatal care. CICCs have garnered attention and adoption owing to their advantageous features. Therefore, achieving clinical competence in ultrasound-guided CICC insertion in term and preterm infants is of paramount importance for neonatologists. A safe clinical training program should include theoretical teaching and clinical practice, simulation and supervised CICC insertions.

METHODS

We planned a training program for neonatologists for ultrasound-guided CICCs placement at our level III neonatal intensive care unit (NICU) in Modena, Italy. In this single-centre prospective observational study, we present the preliminary results of a 12-month training period. Two paediatric anaesthesiologists participated as trainers, and a multidisciplinary team was established for continuing education, consisting of neonatologists, nurses, and anaesthesiologists. We detail the features of our training program and present the modalities of CICC placement in newborns.

RESULTS

The success rate of procedures was 100%. In 80.5% of cases, the insertion was obtained at the first ultrasound-guided venipuncture. No procedure-related complications occurred in neonates (median gestational age 36 weeks, IQR 26-40; median birth weight 1200 g, IQR 622-2930). Three of the six neonatologists (50%) who participated in the clinical training program have achieved good clinical competence. One of them has acquired the necessary skills to in turn supervise other colleagues.

CONCLUSIONS

Our ongoing clinical training program was safe and effective. Conducting the program within the NICU contributes to the implementation of medical and nursing skills of the entire staff.

Review article: Feasibility of brachiocephalic vein central venous access for the resuscitation of shocked adult trauma patients: A literature review

Venous access is a key component of managing haemorrhagic shock. Obtaining intravenous access in trauma patients is challenging due to circulatory collapse in shock. This literature review examines the feasibility of direct puncture and cannulation of the brachiocephalic veins (BCVs) for intravenous access in shocked adult trauma patients. Three literature searches were conducted. OVID Medline was searched for articles on the use of the BCVs for venous access in adults and on the BCVs in shock. A third systematic search of OVID Medline, OVID Embase and Cochrane Library was conducted on the use of the BCVs for access in shocked trauma patients. After full-text review, 18 studies were selected for inclusion for the search on the use of the BCVs for access in adults. No studies met the inclusion criteria for the search on the BCVs in shock and BCV access in shocked trauma patients. The BCVs are currently used for central venous access, haemodialysis and totally implantable venous access devices (TIVADs) in adults. There is a preference for the right BCV (RBCV) over the left as the RBCV is more superficial, straighter, larger, has less anatomical variation and avoids the risk of thoracic duct puncture. The BCVs appear to be stabilised in shock by surrounding bony structures. The BCVs may provide a site for initial, rapid access in trauma resuscitation. Further research is required to determine if the BCVs collapse in shock and if venous access using the BCVs is feasible in a trauma resuscitation setting.

Comparison between in-plane and out-of-plane techniques for ultrasound guided cannulation of the left brachiocephalic vein in pediatric population: A randomised controlled trial

BACKGROUND AND AIMS

Brachiocephalic vein is a novel site for central venous cannulation in infants. It becomes useful in patients where the internal jugular vein lumen is small (e.g., volume deficient patient), patients with a history of multiple cannulations, and in whom subclavian puncture is contraindicated.

METHODS

In this randomized double-blinded study, 100 patients, aged between 0 and 1 year scheduled for elective central venous cannulation were recruited. The patients were allocated into two groups (50 patients in each). Group I patients had ultrasound (US) guided cannulation of the left brachiocephalic vein (BCV) by inserting a needle in-plane to the US probe from lateral to the medial direction, whereas Group II patients underwent cannulation of the BCV via an out-of-plane approach.

RESULTS

The first-attempt success rate was significantly higher in Group I (74%) than in Group II (36%) (p < 0.001). The total success rate was higher in group I (98%) than in group II (88%) however the difference was statistically insignificant (p > 0.05). The mean BCV cannulation time was significantly shorter in group I (35.46 ± 25.10) than in group II (65.24 ± 40.26) (p < 0.001). The rate of unsuccessful BCV cannulation (12%) and hematoma development (12%) was significantly higher in group II than in group I (2%).

CONCLUSION

Compared to the out-of-plane approach of left BCV cannulation, US-guided in-plane cannulation of the left BCV increased the first-attempt success rate, decreased the number of puncture attempts, and decreased the time required for cannulation.

Distance that the catheter covers from skin to the vein using the US-guided in-plane technique: The impact of footprint of the probe and depth of the vein

Employing the in-plane technique in infants the footprint of the ultrasound probe should be considered along with the depth of the vein, and the angle between the needle and the face of the probe, which is crucial in optimization of the visibility of the needle in the beam. Three different ultrasound probes are evaluated for different depths of vein. The hockey-stick probe provided a shorter minimum distance while maintaining the angle between the needle and the face of the probe within an optimal range for visualization of the needle in the beam, supporting its recommendation for infants with regard to its frequency and physical size.

The neonatal DAV-expert algorithm: a GAVeCeLT/GAVePed consensus for the choice of the most appropriate venous access in newborns

In most NICUs, the choice of the venous access device currently relies upon the operator's experience and preferences. However, considering the high failure rate of vascular devices in the neonatal population, such clinical choice has a 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 in line with the current scientific evidence. 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 the neonatal population. After a systematic review of the available evidence, the panel of the consensus (which included Italian neonatologists specifically experts in this area) has provided structured recommendations answering four sets of questions regarding (1) umbilical venous catheters, (2) peripheral cannulas, (3) epicutaneo-cava catheters, and (4) ultrasound-guided centrally and femorally inserted central catheters. 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.  Conclusion: The goal of the present consensus is to offer a systematic set of recommendations on the choice of the most appropriate vascular access device in Neonatal Intensive Care Unit.

Subaortic left brachiocephalic vein and real-time ultrasound-guided puncture

We describe a subaortic left brachiocephalic vein, a congenital anomaly that can be suspected during the rapid central vein assessment before central venous catheterization. Since the vein descends vertically/obliquely rapidly from its origin, we suggest that the puncture should be made at a greater angle (50°-60°) than what is usually used to puncture this vein (20°-30°). Failure to identify this anomaly may cause a failed puncture or complications from the puncture of adjacent blood vessels.

US-guided central venous catheter placement in the neonatal intensive care unit: Brachiocephalic vein or internal jugular vein?

BACKGROUND

Centrally inserted central catheters (CICCs) are commonly used to monitor venous pressure and administer parenteral nutrition and drugs in newborns. In the present study, we evaluated cannulation success rates, cannulation time, and frequency of complications in catheterization of the internal jugular vein (IJV) and brachiocephalic vein (BCV).

METHODS

The present study included patients who underwent IJV and BCV catheterization under ultrasound (US) guidance. The patients were divided into two groups, IJV and BCV, depending on the vein in which the CICC was utilized. We documented the diameters of the IJVs and BCVs, first attempt and overall success rates, mean cannulation time, and complication rates.

RESULTS

A total of 79 patients were evaluated, 37 in the BCV group and 42 in the IJV group. No significant differences were observed between the two groups in terms of sex, mean age, or weight range (p > 0.05).The mean vein diameter was significantly larger in the BCV group than in the IJV group (p < 0.001); the mean number of attempts was significantly higher in the IJV group than in the BCV group (p < 0.001); the mean cannulation time was significantly longer in the IJV group than in the BCV group (p < 0.001); and the first attempt success rate was 50% in the IJV group, versus 94.6% in the BCV group. The overall success rate was 100% in both groups. The rate of complications was 8.6% in the IJV group, while no complications developed in the BCV group.

CONCLUSIONS

Given the larger diameter of the vessel, BCV catheterization was found to result in quicker cannulation and lower complication rates. The results of the present study suggest that BCV catheterization should be the first choice for neonatal intensive care unit (NICU) patients who require parenteral support or close venous pressure monitoring.

Ultrasound-guided totally implantable venous access ports placement via right brachiocephalic vein in pediatric population: A clinical debut

BACKGROUND AND OBJECTIVES

To investigate the feasibility and safety of ultrasound-guided totally implantable venous access ports (TIVAPs) via the right brachiocephalic vein (BCV) in pediatric patients.

METHODS

A single-institute retrospective review was performed on 35 pediatric patients with predominantly hematological malignancies (88.6%) who underwent TIVAP implantation via ultrasound-guided right BCV approach from July 2018 to June 2021. The catheter tip was adjusted to be positioned at the cavoatrial junction under pulsed fluoroscopic guidance. Technical success rate, procedural information, and TIVAP-related complications were evaluated.

RESULTS

All the pediatric TIVAP devices were successfully implanted via right BCV access. Venous access was successful by first attempt in 32 children (91%), two cases (5.7%) required a second attempt, and one patient (2.9%) required a third attempt. The mean procedural time was 44.6 ± 6.4 minutes (range: 34-62 minutes). No intraoperative complications occurred. The average TIVAP indwelling time was 564 ± 208 days (range: 193-1014 days), with a cumulative 19,723 catheter-days. Overall, three patients (8.6%) experienced four postoperative complications (two cases of local hematoma and two catheter dysfunctions) at a rate of 0.2 per 1000 catheter-days. No other complications such as wound dehiscence, delayed incision healing, catheter-related thrombosis (CRT), catheter malposition/fracture, surgical site infection, catheter-related bloodstream infection (CRBSI), pinch-off syndrome, and drug extravasation were observed during follow-up.

CONCLUSIONS

Ultrasound-guided right BCV access for TIVAP placement in pediatric patients appears to be technically feasible, safe, and effective. Further large-sample, prospective studies are warranted.

Comparison of ultrasound-guided internal jugular vein and supraclavicular subclavian vein catheterization in critically ill patients: a prospective, randomized clinical trial

Background

The aim of this study was to compare the effectiveness and safety of ultrasound-guided out-of-plane internal jugular vein (OOP-IJV) and in-plane supraclavicular subclavian vein (IP-SSCV) catheterization in adult intensive care unit.

Methods

A total of 250 consecutive patients requiring central venous catheterization, were randomly assigned to undergo either ultrasound-guided OOP-IJV or IP-SSCV cannulation. All catheterizations were carried out by three physicians. The primary outcome was the first attempt success rate. Ultrasound scanning time, venous puncture time, insertion time, overall access time, number of puncture attempts, number of needle redirections, success rate, guidewire advancing difficulties, venous collapse and adverse events were also documented.

Results

The first attempt success rate was significantly higher in IP-SSCV group (83.2%) compared to OOP-IJV group (63.2%) (p = 0.001). The IP-SSCV group was associated with a longer ultrasound scanning time (16.54 ± 13.51 vs. 5.26 ± 4.05 s; p < 0.001) and a shorter insertion time (43.98 ± 26.77 vs. 53.12 ± 40.21 s; p = 0.038). In the IP-SCCV group, we recorded a fewer number of puncture attempts (1.16 ± 0.39 vs. 1.47 ± 0.71; p < 0.001), needle redirections (0.69 ± 0.58 vs. 1.17 ± 0.95; p < 0.001), difficulties in guidewire advancement (2.4% vs. 27.4%; p < 0.001), venous collapse (2.4%, vs. 18.4%; p < 0.001) and adverse events (8.8% vs. 13.6%; p = 0.22).

Conclusions

The IP-SSCV approach is an effective and a safe alternative to the classic OOP-IJV catheterization in critical adult patients.

Comparison of ultrasound-guided internal jugular vein cannulation versus supraclavicular approach to brachiocephalic vein cannulation– A prospective, single-blind, randomised study

Background and Aims:

The internal jugular vein (IJV) is the most common site for central venous cannulation. Ultrasonography (USG)-guided brachiocephalic vein (BCV) cannulation has been described recently. The objective of this study was to compare the first attempt success rate, overall success rate and procedural ease between two techniques.

Methods:

This was a prospective, single-blinded, randomised clinical study. Patients were randomly allocated into two groups using computer generated random table. Group IJV included 55 patients of USG-guided out-of-plane approach to the right IJV cannulation and group BCV included 55 patients for USG-guided supraclavicular in-plane approach to right BCV cannulation. The success rate, number of redirections needed, vein and needle tip visualisation, cannulation time and complication rate were compared between the groups.

Results:

Demographic parameters were similar between the groups. Success rate of cannulation was 98.5% in IJV group and 100% in group BCV (P = 0.31). The first attempt success rate was 76.3% and 81.81% in IJV and BCV group, respectively (P = 0.42). IJV was collapsed in 14.5% cases and BCV was collapsed in 0.9% cases. The needle visualisation was better in BCV group (94.54%) compared to IJV (80%) (P = 0.02) group, which was statistically significant. The numbers of redirections of needle were more in IJV group. Thus the procedural ease was better with BCV than IJV.

Conclusion:

Supraclavicular USG-guided in-plane BCV cannulation is a good alternative to USG-guided out-of-plane IJV cannulation, because of good calibre of the vein and better needle visualisation in the BCV group.

Ultrasound-guided brachiocephalic vein access in neonates and pediatric patients

Central venous accesses in neonates and pediatric patients represent a common and important procedure for both, intraoperative and postoperative care. Point-of-care ultrasound-guided technique has been proposed to increased success rate and efficiency, as well as to decrease the number of complications. Ultrasound-guided internal jugular vein cannulation is considering the "gold standard" in children. Another central venous cannulation option in neonates and children has been supraclavicular ultrasound-guided cannulation of the brachiocephalic vein using the in-plane approach. This article gives a review of the current evidence, the basic knowledge of the technique and the structured approach to follow for supraclavicular ultrasound-guided brachiocephalic vein access in children and neonates.

A Novel Method for Ultrasound-Guided Central Catheter Placement-Supraclavicular Brachiocephalic Vein Catheterization Versus Jugular Catheterization: A Prospective Randomized Study

OBJECTIVES

To assess the superiority of a novel ultrasound-guided central venous catheterization technique, supraclavicular brachiocephalic catheterization, compared to jugular vein catheterization.

DESIGN

Prospective randomized trial.

SETTING

Operating rooms and intensive care unit.

PARTICIPANTS

Eighty-six patients with central catheter placement were included in the present study.

INTERVENTIONS

In the brachiocephalic group, ultrasound-guided catheterization of the brachiocephalic vein was performed via the supraclavicular route using needle-in-plane and syringe-free techniques. In the jugular group, ultrasound-guided catheterization of the internal jugular vein was performed using the needle-out-of-plane technique.

MEASUREMENTS AND MAIN RESULTS

Measurements included number of needle insertion attempts, ultrasonography times, and cannulation times. Additionally, ultrasound visibility of the veins, needle, guidewire, and catheter, as well as ease of the procedure, were assessed. Mean cannulation time was 27.65 ± 25.36 seconds in Group B and 28.16 ± 21.72 seconds in Group J. The overall success rate was 97.6% in Group B and 97.7% in Group J. The mean ease score of the cannulation procedure was 8.78 ± 1.13 in Group B and 8.67 ± 1.23 in Group J. No significant differences were detected between groups. The mean ultrasonography time was 11.98 ± 6.91 seconds in Group B and 2.88 ± 1.47 seconds in Group J. Ultrasound visibility of the brachiocephalic, jugular, and subclavian veins, as well as the needle and the guidewire, were good; however, visibility of the catheter was poor.

CONCLUSIONS

Although not superior to the standard internal jugular approach, the novel supraclavicular approach proved to be a noninferior method for central venous cannulation.

Neo-ECHOTIP: A structured protocol for ultrasound-based tip navigation and tip location during placement of central venous access devices in neonates

Central venous access devices are often needed in neonates admitted to Neonatal Intensive Care Unit. The location of the tip of the central catheter is usually assessed by post-procedural X-ray. However, this strategy is inaccurate and time consuming. Recent guidelines strongly recommend intra-procedural methods of tip location, to increase the cost-effectiveness of the maneuver and to shorten the time between device placement and utilization. In this regard, real-time ultrasound represents the most promising tool for tip navigation and location in neonates. The aim of this paper is (a) to review all the evidence available about ultrasound-based tip navigation and tip location of central catheters in the neonatal population (b) to propose a novel protocol for tip navigation and location (Neo-ECHOTIP) based on such evidence.

Acquired chylothorax in association with supraclavicular ultrasound-guided access to the brachiocephalic vein in a neonate

Achieving and maintaining venous access can be challenging in some premature and low birth weight infants. In this population, the supraclavicular ultrasound-guided in-plane approach to the brachiocephalic vein for central venous access has demonstrated great success with a low rate of complications. This case describes the first report of acquired chylothorax in association with this technique, in a previously extremely preterm and low birth weight infant.

Ultrasound-guided cannulation of the brachiocephalic vein in newborns: A novel approach with a supraclavicular view for tip navigation and tip location

PURPOSE

Central vascular catheters (CVCs) are frequently used in newborns in NICU. Ultrasound (US) guided supraclavicular venipuncture of the brachiocephalic vein (BCV) is usually performed with a 12 MHz linear probe and then a catheter tip location is verified with an 8 MHz micro-convex probe or intracavitary ECG (IC-ECG). We explored the feasibility of an US guided puncture using a 7 MHz sector probe, positioned on the clavicular sternal joint. We also explored the opportunity of performing it with a probe tilting tip navigation and tip location.

DESIGN

This is a monocentric retrospective observational study made in the neonatal intensive care unit L. Vanvitelli University Hospital of Naples, Italy.

PATIENTS

Forty newborns in NICU scheduled for an ultrasound guided CVC.

INTERVENTIONS

US guided brachiocephalic vein catheterization. We used A long axis in plane supraclavicular approach to the BCV for real time puncture, for tip navigation and tip location, using a 7 MHz sector transducer. We executed an ultrasound pre-scan of the Y-shape (right and left BCV, superior vena cava (SVC)) and of the right pulmonary artery (RPA), and then we performed a guided sterile puncture on middle third of supraclavicular fossa next to clavicular sternal joint with a 7 MHz. We used the same probe for tip navigation by this supraclavicular short axis of ascending aorta view. Tip location was confirmed with the ultrasound and IC-ECG.

RESULTS

In all infants the ultrasound tip navigation and tip location were successful and were confirmed by IC-ECG. No misplacement, arterial puncture or pneumothorax occurred.

CONCLUSIONS

The supraclavicular view performed with a 7 MHz sector probe has proved to be completely safe and to be a method with 100% feasibility.

Practice Patterns of Central Venous Catheter Placement and Confirmation in Pediatric Critical Care

Optimal practices for the placement of central venous catheters (CVCs) in critically ill children are unclear. This study describes the clinical practice of pediatric critical care medicine (PCCM) providers regarding CVC placement, including site selection, confirmation practices and assessment of complications. Two-hundred fourteen PCCM providers responded to an electronic survey, including 170 (79%) attending physicians, 30 (14%) fellow physicians, and 14 (7%) advanced practice providers. PCCM providers most commonly place internal jugular (IJ) and femoral CVCs, with subclavian CVCs and peripherally inserted central catheters (PICCs) placed less commonly (IJ 99%, femoral 95%, subclavian 40%, PICC 19%). The IJ is the most preferred site (128/214 (60%)); decreased infection risk is the most common reason for preferring this site. The subclavian is the least preferred site (150/214 [70%]) due to concern for increased risk of complications (51%) and personal discomfort with the procedure (49%). One-hundred twenty-six (59%) of respondents reported receiving formal ultrasound (US) or echocardiography training. Respondents reported using dynamic US guidance for placement in 90% of IJ, 86% of PICC, 78% of femoral, and 12% of subclavian CVCs. Plain radiography (X-ray) was the most preferred modality for confirming CVC tip position (85%) compared with US (9%) and no imaging (5%). Most providers reported using X-ray to evaluate for pneumothorax following upper extremity CVC placement, with only 5% reporting use of US and none relying on physical exam alone. This study demonstrates wide variability in PCCM providers' CVC placement practices. Potential training gaps exist for placement of subclavian catheters and use of US.

Perioperative and Postoperative Complications of Supraclavicular, Ultrasound-Guided, Totally Implantable Venous Access Port via the Brachiocephalic Vein in Adult Patients: A Retrospective Multicentre Study

Purpose

The totally implantable venous access port (TIVAP) provides patients with safe, effective and long-term convenient venous access for the administration of medications such as chemotherapy drugs. The implantation and long-term use of TIVAP are related to thrombosis, infection and other complications. In this study, the medical records of multicentre patients were collected, and the perioperative and postoperative complications were retrospectively analysed to objectively evaluate the safety of the implantation of supraclavicular, ultrasound-guided TIVAP via the brachiocephalic vein (BCV).

Patients and Methods

We retrospectively analysed the clinical data of 433 adult patients who had undergone ultrasound-guided TIVAP implantation via the BCV at four hospitals in China from March 2018 to May 2019. The success rates of the first puncture, operation time, and perioperative and postoperative complications were analysed.

Results

All the TIVAPs were implanted successfully (100%). The average TIVAP carrying time was 318.15 ±44.22 days (range: 38–502 days) for a total of 197,694 catheter days. The success rate of the first puncture was 94.92% (411/433), and the average operation time was 29.66 ±7.45 min (range: 18–60 min). The perioperative complications included arterial puncture in 4 patients and pneumothorax in 1 patient. The incidence of postoperative complications was 5.08% (22/433), including poor incision healing (n = 2), catheter-related infection (n = 3), port infection (n = 6), thrombosis (n = 2) and fibrin sheath formation (n = 8). Another patient had infusion disturbance 2 days after the operation, and chest X-ray showed bending at the connection between the catheter and port. No other serious complications occurred, such as catheter rupture and drug leakage. The total incidence of complications was 6.24% (27/433).

Conclusion

This study showed excellent tolerance of supraclavicular, ultrasound-guided BCV puncture to implant TIVAP and a low incidence of complications. As a safe and effective method of TIVAP implantation, it can provide a new choice for clinicians.

Ultrasound-guided percutaneous brachiocephalic vein cannulation for ventriculoatrial shunt placement in a child

OBJECTIVE

As far as the ventriculoatrial shunt placement in children is concerned, the percutaneous approach to the internal jugular vein under ultrasonographic control has been hitherto strongly recommended. Unfortunately, children still represent a challenge, having them peculiar characteristics for which the internal jugular vein cannulation shows some disadvantages.

METHODS

In this manuscript, we describe a percutaneous placement of ventriculoatrial shunt via right brachiocephalic vein under intraoperative ultrasonographic control.

CONCLUSIONS

Brachiocephalic vein cannulation in surgery provides notable advantages in paediatric population and it may be considered as the first choice in younger children.

Expert consensus-based clinical practice guidelines management of intravascular catheters in the intensive care unit

The French Society of Intensive Care Medicine (SRLF), jointly with the French-Speaking Group of Paediatric Emergency Rooms and Intensive Care Units (GFRUP) and the French-Speaking Association of Paediatric Surgical Intensivists (ADARPEF), worked out guidelines for the management of central venous catheters (CVC), arterial catheters and dialysis catheters in intensive care unit. For adult patients: Using GRADE methodology, 36 recommendations for an improved catheter management were produced by the 22 experts. Recommendations regarding catheter-related infections’ prevention included the preferential use of subclavian central vein (GRADE 1), a one-step skin disinfection(GRADE 1) using 2% chlorhexidine (CHG)-alcohol (GRADE 1), and the implementation of a quality of care improvement program. Antiseptic- or antibiotic-impregnated CVC should likely not be used (GRADE 2, for children and adults). Catheter dressings should likely not be changed before the 7th day, except when the dressing gets detached, soiled or impregnated with blood (GRADE 2− adults). CHG dressings should likely be used (GRADE 2+). For adults and children, ultrasound guidance should be used to reduce mechanical complications in case of internal jugular access (GRADE 1), subclavian access (Grade 2) and femoral venous, arterial radial and femoral access (Expert opinion). For children, an ultrasound-guided supraclavicular approach of the brachiocephalic vein was recommended to reduce the number of attempts for cannulation and mechanical complications. Based on scarce publications on diagnostic and therapeutic strategies and on their experience (expert opinion), the panel proposed definitions, and therapeutic strategies.

Feasibility of the ultrasound-guided supraclavicular cannulation of the brachiocephalic vein in very small weight infants: A case series

BACKGROUND

The aim of this retrospective analysis was to evaluate the clinical feasibility of the supraclavicular ultrasound-guided cannulation of the brachiocephalic vein in infants weighing less than 1500 g.

METHODS

The ultrasound probe was placed in the supraclavicular region so as to obtain the optimum sonographic long-axis view of the brachiocephalic vein. By using an in-plane approach the brachiocephalic vein was cannulated by using a 24-gauge intravenous cannula under real-time ultrasound guidance into the vein followed by the insertion of a 2-French single lumen catheter using the Seldinger technique.

RESULTS

Forty-six brachiocephalic vein cannulations in infants weighing between 0.55 and 1.5 kg (Median: 1.2; 95%-CI: 0.9-1.2) were included. Ultimate success rate was 89.1% (41 out of 46). One cannulation attempt was required in 30 (65.2%) patients, 2 in 6 (13%) and 3 in 5 (10.8%), respectively. Smaller weight babies did not require significantly more cannulation attempts. The probability of successful cannulation on the first attempt increased significantly from 40% (2010) to more than 80% (2019) over the time course of this series. Median catheter dwell time was 15 days (95%-CI: 9-20) with one catheter being removed prematurely after 8 days due to obstruction.

CONCLUSION

Supracalvicular in-plane real-time ultrasound-guided cannulation of the brachiocephalic vein seems to be a convenient and feasible option to provide large-bore central venous access for very small and sick babies.

Centrally inserted central catheters in preterm neonates with weight below 1500 g by ultrasound-guided access to the brachio-cephalic vein

OBJECTIVE

Central venous access in critically ill newborns can be challenging. Ultrasound-guided brachio-cephalic vein catheterization is a relatively new procedure, recently introduced in several neonatal intensive care units.

Real-time ultrasound-guided supraclavicular technique as a possible alternative approach for Hickman catheter implantation

BACKGROUND

Tunneled Hickman/Broviac central venous catheter implantation is performed when patients require a central vein route for long-term therapy. The subclavian or internal jugular vein approach is often chosen for their implantation sites. However, access to the central vein can be difficult owing to thrombosis or stenosis when the same vein has already been accessed several times. In such situations, other possible alternative approaches to the central vein should be considered to avoid serious complications owing to further unsuccessful attempts.

DESCRIPTION OF OPERATIVE TECHNIQUE

We encountered a 1-year-old patient admitted to our hospital for a Hickman catheter implantation after multiple unsuccessful attempts at central venous catheter insertion via bilateral subclavian approaches in another hospital. An ultrasound showed that no more subclavian veins were available on either side. A real-time ultrasound-guided right supraclavicular approach was performed as a solution to this situation.

CONCLUSIONS

In this article, we introduce a real-time ultrasound-guided supraclavicular approach as a possible alternative method for Hickman catheter implantation. We present step-by-step instructions including figures and a video and further discuss the advantages and disadvantages of this procedure, comparing the right and left approaches with references to existing literature.

Pre-procedural ultrasound-guided evaluation of left internal jugular vein and brachiocephalic vein: Experience on infants <1 year

Pre-procedural evaluation of central veins prior to cannulation with ultrasound is essential to reduce the complication rates as well as to increase the success rates. The left brachiocephalic vein has been suggested to be considered as first choice in infants including the neonates due to its larger diameter and ease of access with supraclavicular, ultrasound-guided, in-plane technique. There are few studies on neonates and infants comparing the diameter of brachiocephalic vein with internal jugular vein being its most common alternative. The aim of the present report is to share our observations pertaining to the pre-procedural measurements of the diameters of left internal jugular vein and brachiocephalic vein in infants <1 year. The measurements were analysed in accordance with the weights of the infants (<2500 g and ⩾2500 g). In infants <2500 g, the brachiocephalic vein was larger than the internal jugular vein (4.0 ± 0.7 (3.2-5.2) mm vs 3.2 ± 0.7 (1.9- 4.3) mm, p = 0.032), whereas the diameters of two major veins were similar in infants ⩾2500 g (4.8 ± 1.2 (2.3-6.4) mm vs 5.1 ± 0.9 (2.8-6.7) mm, p = 0.363). Our observations support the suggestion of the brachiocephalic vein to be considered as the first choice for large-bore cannulation due to its larger diameter as well as its other advantages, especially in neonates <2500 g.

Comparison between ultrasound-guided TIVAD via the right innominate vein and the right internal jugular vein approach

BACKGROUND

To compare the efficacy and safety of right internal jugular vein (IJV) approach and right innominate vein (INV) approach for US-guided totally implantable venous access devices (TIVADs), and to explore the advantages and disadvantages of the two approaches.

METHODS

Six hundred and nineteen adult patients had long-term infusion and chemotherapy needs and inconvenience of peripheral venous infusion. Right INV approach was used to implant 339 cases of TIVADs, and right IJV approach was used to implant 280 cases of TIVADs. The success rate of one-time catheterization and the incidence of complications in the two groups were retrospectively analyzed.

RESULTS

All patients were successfully implanted in TIVAD. The success rates of one-time puncture in INV group and IJV approach group were 98.53% (334/339) and 95.36% (267/280), respectively. There was significant difference between the two groups (P = 0.020). The incidence of perioperative complications and long-term complications in the right INV group were 1.18% (4/339) and 3.54% (12/339), respectively, while those in the right IJV group were 1.43% (4280) and 3.93% (11280). There was no significant difference in the incidence of perioperative or long-term complications between the two groups (P = 0.785, P = 0.799, respectively).

CONCLUSIONS

US-guided TIVADs via the right INV approach and the right IJV approach are both safe and reliable. The right INV approach improves the one-time puncture success rate, as long as the technique is properly operated, serious complications rarely occur.

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.

Ultrasound-guided supraclavicular brachiocephalic vein catheterization in children: Syringe-free in-plane technique with micro-convex probe

Central venous catheterization of children is often a challenging procedure due to small anatomical structures. Ultrasound guidance has been shown to reduce complications and improve cannulation success as compared with the landmark-based technique. In-plane techniques allow for longitudinal visualization of the vessels and real-time visualization of needle track during its advancement. When in-plane and syringe-free techniques are combined, advancement of the guidewire can also be visualized. We aim to introduce our supraclavicular approach for brachiocephalic vein cannulation in pediatric patients. A syringe-free and in-plane technique is used to cannulate the patients. The subclavian, jugular, and the brachiocephalic veins were visualized by endocavity micro-convex ultrasound probe as a Y shape during the cannulation procedure. We present a case series of successful cannulation by using this technique.

Supraclavicular approach for subclavian vein catheterization in pediatric anesthesia: The reborn of an ancient technique with the ultrasound's assistance

The insertion of a central venous catheter is a procedure frequently performed in paediatric anaesthesia. The most frequent approach for this procedure is the internal jugular vein. However, some specific factors in children, such as the short neck and the easy collapse of this vein, which is accentuated in situations such as hypovolaemia and changes in the respiratory pattern, can lead to greater difficulty. The supraclavicular approach of the subclavian vein was described more than 50 years ago. However, it is not often considered nowadays, even after the introduction of ultrasound, and despite the obvious advantages with respect to the internal jugular approach due to the lower incidence of thrombosis and infection. This document reviews the considerations of the supraclavicular approach according to the available evidence in paediatric anaesthesia, discusses the feasibility and safety of the procedure, and finally describes the technique of ultrasound--guided puncture.

A Systematic Ultrasound Evaluation of the Diameter of Deep Veins in the Newborn: Results and Implications for Clinical Practice

BACKGROUND

In adults and children, current guidelines recommend measuring the diameter of the vein before the insertion of central catheters, in order to match vein diameter with catheter caliber and thus reduce the risk of venous thrombosis. In the neonatal intensive care unit, central catheters are often used but the vein diameter is usually not considered.

METHOD

We assessed the diameter of the most relevant deep veins in 100 newborns, using a strict protocol of ultrasound evaluation.

RESULTS

Mean gestational age of studied infants was 32 weeks and mean weight was 1,690 g. The mean diameter of the brachiocephalic vein was consistently ≥3 mm, with no significant difference between the right and the left side. The femoral vein diameter, on the other hand, was considerably smaller than 3 mm for infants with a weight < 2,000 g. Interobserver repeatability was found to be very high.

CONCLUSION

Preprocedural ultrasound scan of veins is feasible and easy, also in newborns, and it should be recommended for optimizing central venous catheterization.

Choosing Wisely in pediatric anesthesia: An interpretation from the German Scientific Working Group of Paediatric Anaesthesia (WAKKA)

Inspired by the Choosing Wisely initiative, a group of pediatric anesthesiologists representing the German Working Group on Paediatric Anaesthesia (WAKKA) coined and agreed upon 10 concise positive ("dos") or negative ("don'ts") evidence-based recommendations. (i) In infants and children with robust indications for surgical, interventional, or diagnostic procedures, anesthesia or sedation should not be avoided or delayed due to the potential neurotoxicity associated with the exposure to anesthetics. (ii) In children without relevant preexisting illnesses (ie, ASA status I/II) who are scheduled for elective minor or medium-risk surgical procedures, no routine blood tests should be performed. (iii) Parental presence during the induction of anesthesia should be an option for children whenever possible. (iv) Perioperative fasting should be safe and child-friendly with shorter real fasting times and more liberal postoperative drinking and enteral feeding. (v) Perioperative fluid therapy should be safe and effective with physiologically composed balanced electrolyte solutions to maintain a normal extracellular fluid volume; addition of 1%-2.5% glucose to avoid lipolysis, hypoglycemia, and hyperglycemia, and colloids as needed to maintain a normal blood volume. (vi) To achieve safe and successful airway management, the locally accepted airway algorithm and continued teaching and training of basic and alternative techniques of ventilation and endotracheal intubation are required. (vii) Ultrasound and imaging systems (eg, transillumination) should be available for achieving central venous access and challenging peripheral venous and arterial access. (viii) Perioperative disturbances of the patient's homeostasis, such as hypotension, hypocapnia, hypothermia, hypoglycemia, hyponatremia, and severe anemia, should not be ignored and should be prevented or treated immediately. (ix) Pediatric patients with an elevated perioperative risk, eg, preterm and term neonates, infants, and critically ill children, should be treated at institutions where all caregivers have sufficient expertise and continuous clinical exposure to such patients. (x) A strategy for preventing postoperative vomiting, emergence delirium, and acute pain should be a part of every anesthetic procedure.

Obtaining central access in challenging pediatric patients

PURPOSE

Central catheter placement is one of the most commonly performed procedures by pediatric surgeons. Here, we present a case series of patients where central access was obtained at our institution with the utilization of a novel ultrasound-guided technique. This series represents the first of its kind where the native, parent vessels were inaccessible, resulting in a challenging situation for providers.

METHODS

A retrospective chart review was performed in pediatric patients (0-17 years) at a tertiary care institution between July 2012 and November 2017 on all central line procedures where ultrasound was utilized to cannulate the brachiocephalic or superior vena cava in face of proximal occlusion. Our group has previous experience utilizing an image-guided in-plane approach to central line placement in the pediatric population. Demographics, operative characteristics, and postoperative complications were reviewed.

RESULTS

A total of 11 procedures were included in this case series where the BC (N = 9) or SVC (N = 2) were cannulated for access. Internal jugular vein cannulation was attempted on each patient unless preoperative imaging demonstrated occlusion. The median operative time was 43 ± 23 min. Most procedures were performed on the right sided (63%), with catheters ranging from 4.2F single lumen to 14F double lumen. Since being placed, three (27%) catheters have been removed, with one due to non-use, one due to sepsis, and the final one due to malposition.

CONCLUSION

With the continued need for long-term central access in the pediatric population, distal vein occlusion or inaccessibility can prove challenging when attempting to obtain central access. Here, demonstrated a safe alternative technique that provides an additional option in the pediatric surgeon's armamentarium for patients with difficult central access.

Supraclavicular catheterization of the brachiocephalic vein: a way to prevent or reduce catheter maintenance-related complications in children

Placement of a central venous catheter (CVC) in the brachiocephalic vein (BCV) via the ultrasound (US)-guided supraclavicular approach was recently described in children. We aimed to determine the CVC maintenance-related complications at this site compared to the others (i.e., the femoral, the subclavian, and the jugular). We performed a retrospective data collection of prospectively registered data on CVC in young children hospitalized in a pediatric intensive care unit (PICU) during a 4-year period (May 2011 to May 2015). The primary outcome was a composite of central line-associated bloodstream infection (CLABSI) and deep-vein thrombosis (CLAT) according to the CVC site. Two hundred and twenty-five children, with respective age and weight of 7.1 (1.3-40.1) months and 7.7 (3.6-16) kg, required 257 CVCs, including 147 (57.2%) inserted in the BCV. The risk of the primary outcome was lower in the BCV than in the other sites (5.4 vs 16.4%; OR: 0.29; 95% CI: 0.12-0.70; p = 0.006). CLABSI incidence density rate (2.8 vs 8.96 per 1000 catheter days, p < 0.001) and CLAT incidence rate (2.7 vs 10%, p = 0.016) were also lower at this site.

CONCLUSION

BCV catheterization via the US-guided supraclavicular approach may decrease CVC maintenance-related complications in children hospitalized in a PICU. What is Known: • Placement of a central venous catheter (CVC) in children is associated with mechanical risks during insertion, and with infectious and thrombotic complications during its maintenance. • Ultrasound (US)-guided supraclavicular catheterization of the brachiocephalic vein (BCV) is feasible in infants and children. What is New: • This observational study suggested that BCV catheterization via the US-guided supraclavicular approach was associated with a lower risk of CVC insertion and maintenance-related complications, compared with the other catheterization sites.

A Retrospective Analysis of the Clinical Effectiveness of Supraclavicular, Ultrasound-guided Brachiocephalic Vein Cannulations in Preterm Infants

Background

The aim of this retrospective analysis was to evaluate the clinical effectiveness of the supraclavicular ultrasound-guided cannulation of the brachiocephalic vein in preterm infants.

Methods

The ultrasound probe was placed in the supraclavicular region so as to obtain the optimum sonographic long-axis view of the brachiocephalic vein. By using a strict in-plane approach the brachiocephalic vein was cannulated by advancing a 22- or 24-gauge iv cannula from lateral to medial under the long axis of the ultrasound probe under real-time ultrasound guidance into the vein.

Results

One hundred and forty-two cannulations in infants weighing between 0.59 and 2.5 kg (median: 2.1; CI: 2.0 to 2.2) were included. Ultimate success rate was 94% (134 of 142). One cannulation attempt was required in 100 (70%) patients, two attempts in 21 (15%), and three attempts in 13 (9%). The smaller the weight of the infant the more attempts were needed. More attempts also were needed for the right brachiocephalic vein, which was primarily targeted in 75 (53%) neonates. One (1%) inadvertent arterial puncture was noted.

Conclusions

This supraclavicular, in-plane, real-time, ultrasound-guided cannulation of the brachiocephalic vein seems to be a convenient and effective method to insert central venous catheters in preterm infants.

Atypical use of PICC in Infants and Small Children: A Unicentric Experience

Introduction

The peripherally inserted central catheters (PICCs) are vascular access devices (VAD) that are increasingly being used in the pediatric population. If a small vein caliber prevents positioning the catheter in the arm, the following step is to position the same catheter in the supraclavicular area, which can be defined as an off-label use or “atypical” approach, first described by Pittiruti.

Materials and methods

We retrospectively reviewed PICC positioning with puncture-site in the supra-clavicular area (“atypical” PICC insertion) and then tunneled on the chest.

Results

Nineteen atypical PICCs were positioned in 18 patients. The median age of patients at the day of implant was 14 months (IQR 3-27 months), and weight 7.5 kg (IQR 4-12 kg). Within this population, 74% of cases scheduled for a typical PICC insertion presented vein caliber too small for this procedure. For this reason, the typical PICC insertion was changed in favor of an atypical PICC procedure. Atypical PICCs were successfully used in 100% of cases without immediate complications.

Conclusions

Atypical PICC positioning is a safe and useful alternative to the conventional technique when there is need for a central vascular access device (CVAD) for mid- or long-term therapy.

Ultrasound-Guided Cannulation of the Brachiocephalic Vein in Infants and Children is Useful and Stable

OBJECTIVE

Ultrasound-guided (USG) cannulation of the brachiocephalic vein (BCV) has been shown to be technically easy. We hypothesised that adoption of USG in-plane cannulation of the BCV as the primary approach to central venous cannulation at our institution would lead to central venous cannulation for a greater variety of indications.

METHODS

We performed retrospective, descriptive comparison of all central lines placed in patients aged <16 years who underwent any surgical operation during calendar years 2012-2014 at a small, free-standing children's hospital. The use and management of a central line was reviewed until the patient was discharged from the hospital. Analysis of the data was performed using simple comparative statistical methods.

RESULTS

Forty-nine patients were identified, 20 who weighed <10 kg and 29 who weighed >10 kg. Cannulation was successful in all patients. No significant late complications occurred. Catheters were well tolerated post-operatively, with no accidental dislodgement and no removal because of discomfort. The average duration of insertion was 6.3 (3-20±3.77) days. Nine catheters were placed for access during emergency surgery. 15 were placed in patients with difficult peripheral intravenous (PIV) access. The central lines remained in place until discharge in 79.6% of patients. In 40% of patients, the PIV catheter was removed, and the central line was retained because of preference. Total parenteral nutrition (TPN) was administered in 11 (22.4%) patients.

CONCLUSION

Cannulation of BCV was well tolerated by children, with an average insertion duration of 6.3 days, which often lasted beyond the removal/failure of the PIV cannula. Catheters were useful for primary venous access during hospitalisation and for short TPN courses.

[Avoidance of complications when dealing with central venous catheters in the treatment of children]

Central venous catheters (CVCs) are an important tool in the treatment of children. The insertion of a catheter may result in different complications depending of the type of catheter, the technique used for the insertion and the location. There are various techniques to reduce the risk of complications. In order to reduce the rate of complications of CVCs it is indispensable to perform a risk-benefit analysis for the individual patient before every insertion. The type of catheter used (for example tunneled catheters versus not-tunneled catheters) influences the rate of catheter-associated infections and the comfort of the patient significantly. The choice of the location is influenced by the expected indwelling time, the weight of the patient and the purpose of the CVC. Insertion via the vena jugularis interna is often chosen because of the reduced rate of complications during insertion. When the planned indwelling time of the catheter is longer or the child is fairly small the vena subclavia appears to be more appropriate. It is of utmost importance that the patient is positioned properly before insertion. Whenever possible the insertion should be performed with the help of ultrasound. The positioning of the catheter should be verified radiographically, possibly sonographically or with an ECG in order to avoid misplacement with potentially severe sequelae. The locally established hygienic guidelines should be strictly adhered to and everyone handling CVCs (doctors, nurses and patients) should have regular training.

Brachiocephalic vein for percutaneous ultrasound-guided central line positioning in children: A 20-month preliminary experience with 109 procedures

BACKGROUND

Ultrasound-guided (USG) cannulation of the brachiocephalic vein (BCV) is gaining worldwide consensus for central venous access in children. This study reports a 20-month experience with this approach in children.

METHODS

All patients who underwent percutaneous USG central venous catheter (CVC) positioning in the BCV between August 2013 and March 2015 have been included. Devices inserted during this period were open-ended, either single or double-lumen tunneled CVC. Our series was divided into three consecutive study periods in order to determine the relative incidence of repositioning and complications.

RESULTS

During the study period, a total of 95 patients underwent 109 CVC insertions in the BCV. The median length of CVC duration was 230 days for a total of 23,212 catheter days. No major intraoperative complications occurred. Overall rate of CVC-related postoperative complications requiring repositioning or precocious removal was 0.90 per 1,000 catheter days and involved 21 CVC (19%, 95% confidence interval 13-28). These included 18 dislodgments, two infections, and one malfunction. Double-lumen CVCs represented the only significant risk factor for complications (52% complications-three per 1,000 catheter days).

CONCLUSION

USG supraclavicular cannulation of the BCV represents a safe approach for central line placement in children. It proved to be versatile, as it can be used in premature infants as well as in adolescents. Provided it is adopted by operators experienced in USG cannulation, we strongly suggest to resort to this approach as a first-line choice in children undergoing tunnelled central line placement for long-lasting therapy.

Ultrasound-Guided Subclavian Vein Cannulation in Low Birth Weight Neonates

OBJECTIVES

Central venous access in critically ill, small infants remains technically challenging even in experienced hands. Several vascular accesses exist, but the subclavian vein is often preferred for central venous catheter insertion in infants where abdominal malformation and/or closure of the vein preclude the use of umbilical venous catheters, as catheterization of the subclavian vein is easier in very short necks than the internal jugular vein for age-related anatomical reasons. The subclavian vein approach is yet relatively undescribed in low birth weight infants (i.e., < 2,500 g), and this study aims to explore the feasibility of this technique in very small infants.

DESIGN

Retrospective data collection of prospectively registered data on central venous catheter insertion in infants.

SETTING

Neonatal ICU and PICU at a university hospital.

PATIENTS

One hundred and five newborn children hospitalized in at the ICU.

INTERVENTIONS

An ultrasound-guided supraclavicular approach was applied on all infants who had an subclavian vein catheterization during a 30-month period from January 2013 to July 2015.

MEASUREMENTS AND MAIN RESULTS

One hundred seven supraclavicular subclavian vein catheters were placed in 105 children weighing less than 5,000 g. Among those, 40 patients weighed less than 2,500 g and 10 patients weighed less than 1,500 g. Successful central venous catheter insertion, defined as the correct placement of a functional double-lumen catheter (3F or 4F), was obtained in 97.3%. All three registered failed attempts were due to hematomas from venous bleeding and occurred in infants weighing greater than 2,500 g. No case of accidental arterial puncture or pleural puncture was registered.

CONCLUSIONS

This large series of subclavian vein catheterizations in small infants demonstrates the feasibility of subclavian vein catheterizations even in very small neonates weighing less than 1,500 g.

Supraclavicular Approach to Ultrasound-Guided Brachiocephalic Vein Cannulation in Children and Neonates

The correct choice of intra vascular access in critically ill neonates should be individualized depending on the type and duration of therapy, gestational and chronological age, weight and/or size, diagnosis, clinical status, and venous system patency. Accordingly, there is an ongoing demand for optimization of catheterization. Recently, the use of ultrasound (US)-guided cannulation of the subclavian vein (SCV) has been described in children and neonates. This article gives an overview of the current use of US for achieving central venous catheter placement in the SCV or the brachiocephalic vein (BCV) in neonates. More than 1,250 catheters have been reported inserted in children and neonates for a cumulated success rate of 98.4% and the complication rate is reported to be low. The technical aspects of various approaches are discussed, and we offer our recommendation of an US-guided technique for SCV and BCV cannulation based on our experience in a large NICU setting. Although the cannulation the SCV or BCV does not substitute the use of peripherally inserted central catheters or umbilical venous central catheters in neonates, it is a feasible route in very small children who are in need of a large caliber central venous access.
