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。
To investigate the effect of epidural anesthesia on circulatory function in infants and young children: A prospective study of children under 2 years of age under continuous epidural anesthesia, before and after the block of systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, stroke The output of cardiac output, the cardiac output, ejection rate, ventricular ejection time, lung index and other 9 indicators and the block plane, in which the block plane up to the chest 4 (T4) and chest 6 (T6) in 10 cases; The results showed that the block plane to T4 and T6 two groups of children with epidural block, in addition to heart rate slowed down, the other indicators did not change significantly, suggesting that continuous epidural anesthesia had no significant effect on infant hemodynamics influences.
