【摘要】 本文观察50例腹部手术应用2%利多卡因施行硬膜外阻滞对血流动力学的影响。50例病人分为上和中下腹部两组,每组25例。结果表明:无论上腹部或中下腹部硬膜外阻滞后,其总的趋势是麻醉后平均动脉压、每搏量、每搏指数、左室有效泵力、总外周血管阻力均降低,而心排血量、心脏指数、心率在上腹部组麻醉后下降,在中下腹部组则短时增加后又下降。提示2%利多卡因硬膜外阻滞对血流动力学都有一定程度的抑制作用,尤以上腹部为甚。更多还原

【Abstract】 50 cases of abdominal operation under epidural block with 2% lidocaine were allocated into 2 groups,upper ab- domen group and mid-lower abdomen group,with 25 cases each. The hemodynamic effects were studied by means of XG-Ⅱ Cardiovascular Function Monitor. Results showed that MAP, SV, SVI, LV, VPe and TPR decreased somewhat after blockade in both groups. The CO,CI,HR declined after onset of blockade in the upper abdomen group,while in the mid-lower abdomen,the inhibition of these parameters was preceeded by a transient increase. It is concluded that hemodynamic effects of epidural block were noticeable,especially in upper abdominal cases.更多还原
