异氟醚分娩镇痛对母体血液动力学的影响

目的：前瞻性研究异氰醚分娩镇痛对母体血液动力学的影响。方法：应用国产无创性血液动力学测试仪，对分娩活跃期异氟醚分娩镇痛和对照组产妇共３０例的血液动力学状况进行检测。结果：；实验前后，各组母体血液动力学参数；心率（ＨＲ），每搏量（ＳＶ），每搏指数（ＳＩ），心输出量（ＣＯ），心脏指数（ＣＩ），左室有效泵力（ＶＰＥ），平均动脉压（ＭＡＰ）和总外周阻力（ＴＰＲ）均无显著差异；两组间无显著差异。

The Effect of Isoflurane Analgesia on the Maternal Hemodynamicsduring Normal Labor

To investigate the effect of isoflurane analgesia on the maternal hemodynamics during nor mal labor. Methods 30 primiparae were randomized into two groups:15 as the Analgesit Group and 15 as the Control Group.Their hemodynamic parameters were measured in the active stage of labor by using a uninjured instrument ex-amining hemodynamics.Results before and afer experinment, the maternal haemodynamic parameters,i. e. heart rate(HR), stroke volume (SV), stroke index (SI), cardiac output (CO), cardiac index (CI), ventricular pump efficacy(VPE), mean arterial pressure (MAP), and total peripheral resistance(TPR), did not change significantly in eithergtoup(P> 0. 05); there were no significant differences between the two groups (P > 0. 05 ). Conclusion maternalhaewhyndric state is stable when isofltirane is used for analgesia during active term labor.
