Insights
Practices for placing central venous catheters (CVCs) in critically ill children vary widely among pediatric critical care providers. Most use internal jugular or femoral sites, with less use of subclavian catheters and ultrasound guidance for confirmation.
Area of Science:
- Pediatric Critical Care Medicine
- Vascular Access Procedures
- Medical Device Placement
Background:
- Optimal practices for central venous catheter (CVC) placement in critically ill children remain unclear.
- Significant variability exists in current clinical practices among pediatric critical care medicine (PCCM) providers.
Purpose of the Study:
- To describe current clinical practices of PCCM providers regarding CVC site selection, confirmation methods, and complication assessment.
- To identify potential gaps in training and practice for CVC insertion in pediatric critical care.
Main Methods:
- An electronic survey was distributed to 214 PCCM providers (attending physicians, fellow physicians, advanced practice providers).
- The survey assessed preferred CVC sites, confirmation modalities, and use of ultrasound (US) guidance.
- Respondents reported on training in US or echocardiography for CVC placement.
Main Results:
- Internal jugular (99%) and femoral (95%) sites are most commonly used for CVC placement; subclavian (40%) and peripherally inserted central catheters (PICCs) (19%) are less common.
- The internal jugular site is most preferred (60%), citing decreased infection risk, while the subclavian site is least preferred due to complication concerns.
- Dynamic US guidance is frequently used for IJ (90%), PICC (86%), and femoral (78%) CVCs, but less so for subclavian (12%). Plain radiography (X-ray) is the primary method for confirming tip position (85%) and evaluating pneumothorax.
Conclusions:
- Wide variability exists in CVC placement practices among PCCM providers, highlighting a need for standardized optimal practices.
- Potential training gaps were identified regarding subclavian catheter placement and the utilization of ultrasound for confirmation and complication assessment.
- Further research and standardized training are recommended to improve the safety and efficacy of CVC placement in critically ill children.
Abstract:
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.
