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.
