OBJECTIVE
To compare real-time ultrasound (RT-US) use as an adjunct tool to verify umbilical catheter placement versus standard care without ultrasound.
STUDY DESIGN
Neonates requiring umbilical venous catheter (UVC) and umbilical artery catheter (UAC) placement were randomized into the standard formula (No-US) and the RT-US groups. X-rays were used to confirm the catheter position.
RESULT
Fifty and forty-nine neonates were in the RT-US and No-US groups, respectively. RT- US showed a significantly higher rate of initial X-ray-confirmed proper catheter position than No-US (p < 0.001). The rates of proper positions of UVCs and UACs were significantly higher in the RT-US group than in the No-US group (both p < 0.001). Neonates in the RT-US group required fewer catheter adjustments and subsequent X-rays than those in the No-US group.
CONCLUSION
RT-US enhances the accuracy of UVC and UAC placement, reduces catheter adjustments, and the number of X-rays required.

目的
比较实时超声（RT-US）作为辅助工具用于验证脐静脉导管和脐动脉导管放置情况与不使用超声的标准护理方法。
研究设计
需要放置脐静脉导管（UVC）和脐动脉导管（UAC）的新生儿被随机分为标准组（无超声组）和RT-US组。使用X射线确认导管位置。
结果
RT-US组和无超声组分别有50例和49例新生儿。RT-US组初始X射线确认导管位置正确率显著高于无超声组（p<0.001）。RT-US组UVC和UAC位置正确率显著高于无超声组（均p<0.001）。RT-US组新生儿所需的导管调整次数和后续X射线检查次数均少于无超声组。
结论
RT-US提高了UVC和UAC放置的准确性，减少了导管调整次数以及所需的X射线检查次数。
