Title: Passive Leg Raise in Children
题目：儿童被动抬腿试验
Author作者: Jennifer Guyther

Passive leg raise (PLR) has been studied in adults as a bedside tool to predict volume responsiveness. Can this be applied to children?
 

被动抬腿（PLR）试验已经在成人中被用来研究作为床旁预测容量反应的方法。这个试验方发能适用于儿童吗？
A single center prospective study looked at 40 intensive care patients ranging in age from 1 month to 12.5 years. They used a noninvasive monitoring system that could measure heart rate, stroke volume and cardiac output.
一个单中心前瞻性研究观查了40位年龄为1个月至12.5年的重症监护患者。他们使用了一种非侵入性的监测系统，可以测量心率，每搏输出量和心输出量。
These parameters were measured at a baseline, after PLR, after another baseline and after a 10 ml/kg bolus.
 

这些参数的测量点为：基线，PLR后，回到基线，和10毫升/公斤静脉注射（生理盐水）后。
Overall, changes in the cardiac index varied with PLR. However, there was a statistically significant correlation in children over 5 years showing an increase in cardiac index with PLR and with a fluid bolus.
 

总体而言，心脏指数随PLR改变而变化。然而，5岁以上儿童心指数因PLR和扩容的变化有显著的统计学差异。
Bottom line: In children older than 5 years, PLR can be a quick bedside tool to assess for fluid responsiveness, especially if worried about fluid overload and in an under served area.
要点：对5岁以上的儿童，PLR可以作为快速评估输液反应的床旁手段，尤其是在担心液体超负荷或医疗条件差的地区。
