连续硬膜外阻滞对婴幼儿血流动力学的影响

THE EFFECTS OF EPIDURAL ANESTHESIA ON HEMODYNAMICS IN INFANT

探讨硬膜外阻滞麻醉对婴幼儿循环功能的影响：前瞻性选择２岁以下小儿施行连续硬膜外阻滞麻醉，定时测定阻滞前后收缩压、舒张压、平均动脉压、心率、每搏输出量、分钟心输出量、射血速率指数、心室射血时间、肺液指数等９项指标及阻滞平面，其中阻滞平面达胸４（Ｔ４）和胸６（Ｔ６）各１０例；结果表明阻滞平面达Ｔ４和Ｔ６两组患儿硬膜外阻滞后，除心率减慢之外，其他指标无明显改变，提示连续硬膜外阻滞麻醉对婴幼儿血流动力学无明显影响。

Twenty infants underwent epidural anesthesia were divided into two groups: T 4 group and T 6 group, according to the blocked levels there were 10 cases in each group. The changes on SBP, DBP, MAP, HR, SV, CO, EVI, VET and TFI were systematically observed before and after blocked. The results showed that no changes were found in all indexes except the decreasing of HR in both groups. The study suggested that the epidural anesthesia had no apparent effects on hemodynamics in infant.
