Introduction:
Central venous catheter insertion is routinely performed in adults with high success rates under ultrasound guidance, but guidewire advancement can be difficult in patients with small-caliber veins, particularly in neonates and infants. This randomized exploratory study in adult patients evaluates whether a curved-tip needle, conceptually designed for use in smaller veins, performs at least as well as a standard needle in internal jugular vein (IJV) cannulation.
Methods:
In this prospective, randomized exploratory study, adult patients requiring ultrasound-guided IJV cannulation for any indication were included. Forty participants were randomized into two groups: the curved group (CG), using a curved tip needle (10°), and the standard group (SG), using a conventional straight needle. The primary outcome was the first pass success rate. Secondary objectives were overall success rate, number of attempts, needle visualization, and complications.
Results:
Results were similar in both the CG and SG in terms of first pass success rate (95%), overall success rate (100%), and number of attempts. Needle visualization under ultrasound was similar in both groups. No complications were noted in either group.
Conclusion:
Use of a curved tip needle for IJV catheterization in adults showed similar success rates and needle visualization compared with a conventional straight needle, with no added complications. Further research may explore its utility in non-operative settings, in smaller caliber veins, and at alternative central venous sites.
