Establishing immediate intravenous access to a newborn is challenging even for trained neonatologists in an emergency situation. Correct placement of umbilical catheter or an intraosseous needle needs consistent training. We evaluated the time required to correctly place an emergency umbilical button cannula (EUC) or an umbilical catheter (UC) using the standard intersection (S-EUC or S-UC, respectively) or lateral umbilical cord incision (L-EUC) by untrained medical personnel.
Single-center cross-over pilot-study using a model with fresh umbilical cords. Video-based teaching of medical students before probands performed all three techniques after assignment to one of three cycles with different sequence, using a single umbilical cord divided in three pieces for each proband.
Mean time required to establish L-EUC was 89.3 s, for S-EUC 82.2 s and for S-UC 115.1 s. Both application routes using the EUC were significantly faster than the UC technique. There was no significant difference between both application routes using EUC (p=0.54).
Using an umbilical cannula is faster than an umbilical catheter, using a lateral incision of the umbilical vein is an appropriate alternative.
即使对于训练有素的新生儿科医生而言,在紧急情况下为新生儿立即建立静脉通路也具有挑战性。正确放置脐静脉导管或骨内针需要持续的训练。我们评估了未经培训的医务人员使用标准交叉法(分别为标准紧急脐部按钮式套管针[S-EUC]或标准脐静脉导管[S-UC])或脐静脉外侧切口(L-EUC)正确放置紧急脐部按钮式套管针(EUC)或脐静脉导管(UC)所需的时间。
采用新鲜脐带模型进行单中心交叉试点研究。在将先证者分配到具有不同顺序的三个周期之一后,先对医学生进行基于视频的教学,然后先证者使用为每个先证者分成三段的单根脐带执行所有三种技术。
建立L-EUC所需的平均时间为89.3秒,S-EUC为82.2秒,S-UC为115.1秒。两种使用EUC的应用途径均明显快于UC技术。两种使用EUC的应用途径之间无显著差异(p=0.54)。
使用脐部套管针比使用脐静脉导管更快,采用脐静脉外侧切口是一种合适的替代方法。
