【摘要 】 目的 探讨异氟醚分娩镇痛对子宫胎盘和胎儿胎盘血流的影响。 方法 应用多普勒超声技术，对分娩活跃期异氟醚分娩镇痛组和对照组共50例初产妇的子宫动脉和脐动脉血流速度指数及胎心率进行检测。 结果 实验前后，各组子宫动脉的平均S/D比值、搏动指数(PI)及脐动脉平均S/D比值、PI均无显著差异(P>0.05)；两组间无显著差异(P>0.05)，实验前后，各组平均胎心率均无显著差异(P>0.05)；两组间无显著差异(P>0.05)。 结论 异氟醚分娩镇痛对胎儿-母体循环未发现有不良影响。

【Abstract 】 Objective Tostudy the effect of isoflurane analgesia on uteroplacental and fetoplacental circulationduring normal labor. Methods Fifty primiparae were randomly divided into two groups.25 parturients inhale isoflurane (analgesia group), and 25 parturients do not receive anyform of analgesia (control group). The flow velocity waveforms of the uterine andumbilical arteries were recorded with a continuous-wave Doppler. Results The meanuterine artery and umbilical artery S/D ratios and PIs did not change significantly beforeand after experiment, in either group (P>0.05); and there were no differences betweenthe two groups (P>0.05). There was no significant change in the mean fetal heart raterelative to the values before experiment in either group or between the two groups(P>0.05). Conclusion The inhalation of isoflurane has no satisfactory effect on feto-maternal circulation during normal labor.
