Comparison of catheter-related infection and tip colonization between internal jugular and subclavian central venous catheters in surgical neonates.

BACKGROUND: The primary aim of this study was to compare catheter-associated infections and tip contaminations between percutaneously placed central venous catheters in the internal jugular and subclavian veins in surgical neonates undergoing major noncardiac surgery.

METHODS: The prospectively computerized protocols of 295 procedures were analyzed retrospectively.

RESULTS: One hundred twenty-nine internal jugular venous (group I) and 107 subclavian venous catheters (group S) were included. The median postconceptual age was 37 weeks in group I and 38 in group S. The weight ranged from 580 g to 4.5 kg in group I and from 820 g to 4.5 kg in group S at the time of insertion. Significantly more catheter-associated infections were observed in group I (15.5 vs. 4.7%; chi-square analysis: P < 0.01). The internal jugular venous catheters were also associated with a significantly increased probability of an earlier onset of a catheter-associated infection compared with the subclavian venous catheters (log rank test: P < 0.01; Cox model: P < 0.01). This probability was only slightly increased by a lower weight (Cox model: P = 0.075), and it was not increased by a lower age (Cox model: P = 0.93). Significantly more catheter tips were contaminated by pathogens in group I (55.8 vs. 33.6%; chi-square analysis: P < 0.01).

CONCLUSION: The internal jugular venous catheters were associated with a higher infection rate as well as earlier onset of catheter-associated infection compared with the subclavian venous catheters.
