Catheterization of the umbilical vessels has proven to be an effective and relatively rapid method for gaining central vascular access in neonates. However, it can be technically difficult, the procedure may last 30 min or longer, and it can be associated with complications in some patients. We suggest using a coronary guidewire during catheterization of umbilical vessels to support the placement of umbilical catheters and significantly reduce a risk for complications. We tested the proposed technique in 6 successful ex vivo bench tests of catheterization of the umbilical vessels in stillborn piglets immediately after birth. We are confident that using coronary guidewire as a guiding tool during catheterization of the umbilical vessels is a rapid and safe method. We expect that it allows to obtain a vascular access with lower risk for dangerous procedural complications, which could be a lifesaving in critically ill patients. However, the approach needs to be validated in a comparative study in neonates.

冠状动脉导丝辅助脐导管放置

脐血管插管已被证明是一种有效且相对快速的方法，可用于获得新生儿的中央血管通路。然而，这在技术上可能很困难，手术可能会持续 30 分钟或更长时间，并且可能与某些患者的并发症有关。我们建议在脐血管插管期间使用冠状导丝来支持脐导管的放置，并显着降低并发症的风险。我们在 6 项成功的离体基准测试中测试了所提出的技术，这些测试是在出生后立即对死产仔猪的脐带血管进行导管插入术。我们相信，在脐血管插管期间使用冠状导丝作为引导工具是一种快速且安全的方法。我们希望它能够获得血管通路，并降低危险手术并发症的风险，这可能会挽救危重患者的生命。然而，该方法需要在新生儿的比较研究中得到验证。
