蛛网膜下腔阻滞麻醉对剖宫产产妇凝血功能及血流动力学的影响

Effect of subarachnoid block anesthesia on coagulation function and hemodynamics in parturients undergoing cesarean section

目的探讨蛛网膜下腔阻滞麻醉对剖宫产产妇凝血功能及血流动力学的影响.方法纳入2018年4月-2020年11月剖宫产产妇80例为对象,随机分入两组.全麻组(40例)产妇予以全身麻醉;腰麻组(40例)产妇予以蛛网膜下腔阻滞麻醉.术前和术后2h测定凝血指标,术前(T0)、手术开始时(T1)、手术开始10min(T2)、胎儿取出时(T3)记录血流动力学指标.结果与术前比,两组产妇术后2h PT和APTT升高,且腰麻组术后2h PT和APTT低于全麻组,有统计学意义(P<0.05).与T0比,两组产妇T1、T2、T3时HR和MAP升高,且腰麻组T2时HR和MAP高于全麻组,有统计学意义(P<0.05).结论蛛网膜下腔阻滞麻醉对剖宫产产妇凝血功能影响较小,可以稳定血流动力学.

0bjective To investigate the efcct of subarachnoid block anesthesia on coagulation function and hemodynamics in parturients undergoing cesarean section.Methods 80 pregnant women from April 2018 to November 2020 were included,80 pregnant women were randomly divided into two groups.General anesthesia group pregnant women were given general anesthesia;pregnant women in the spinal anesthesia group were given subarachnoid block anesthesia.Coagulation indexes were measured before and 2 hours after operation,and hemodynamic indexes were recorded before operation(T_(0)),at the beginning of operation(T_(1)),10 minutes after operation(T_(2)),and at the time of fetal removal(T_(3)).Results Compared with that before operation,PT and APTT increased at 2h after operation in both groups;moreover,PT and APTT at 2h after operation in spinal anesthesia group were lower than those in general anesthesia group(P<0.05).Compared with T_(0),HR and MAP increased at T_(1),T_(2) and T_(3) in both groups;moreover,HR and MAP at T_(2) in spinal anesthesia group were higher than those in general anesthesia group(P<0.05).Conclus ion Subarachnoid block anesthesia has less efeet on coagulation function of cesarean section women,can stabilize hemodynamics.
