Abstract
Background:
Inserting a J-tip guide-wire into a vein’s lumen is often difficult when using the Seldinger or modified Seldinger technique for central venous catheterization (CVC) in newborns. This study was designed to compare the efficacy and safety of guide-wire insertion using the combination of a short peripheral intravenous cannula with a straight-tip guide-wire vs. a needle with a J-tip guide-wire for ultrasound-guided (USG) cannulation of the internal jugular vein (IJV) in newborns using an in-plane technique.
Methods:
One hundred and thirty newborn patients (weight, 1.4-5.2 kg) scheduled for selective or emergency surgery, were randomly assigned to either the needle group (combined with a J-tip guide-wire) or cannula group (combined with a straight-tip guide-wire). The primary outcome was the rate of successful guide-wire insertion on the first attempt. The puncture attempts, catheter placement attempts, and mechanical complications were also compared between the groups.
Results:
The rate of successful guide-wire insertion on the first attempt was higher in the cannula group (97%) than in the needle group (76%) (p < 0.05, χ2 = 11.233). Moreover, fewer insertion attempts were needed in the cannula group (1.0 ± 0.2) than in the needle group (1.7 ± 1.1) (p < 0.05, 95% CI [0.449, 1.028]). The time to successful guide-wire insertion was shorter in the cannula group (63 ± 32 s) than in the needle group (92±50 s) (p < 0.05, 95% CI [14.024, 43.063]). No differences were found about other catheterization parameters and complications between the groups.
Conclusion:
The short peripheral cannula combined with a straight-tip guide-wire was superior to the needle combined with a J-tip guide-wire for USG newborn IJV catheterization in terms of successful guide-wire insertion on the first attempt and overall number of insertion attempts.
