腰硬联合麻醉与笑气吸入分娩镇痛的临床研究

目的：观察研究腰硬联合麻醉镇痛法和笑气吸入法的临床效果及对产妇和新生儿的影响。方法：回顾性分析330例产妇，每组110例；其中硬膜外组采用腰硬联合麻醉，笑气组采用吸入含50％笑气和50％氧气的混合气体，对照组未用任何镇痛方法。观察各组的镇痛效果。结果：硬膜外组与笑气组镇痛效果显著优于对照组，硬膜外组镇痛效果、宫口开全（T3）后宫缩强度明显高于笑气组，第一产程孕妇活跃期短；分娩方式硬膜外组与笑气组显著优于对照组；新生儿不良反应、产后出血量、新生儿Apgar评分比较3组无明显差异。结论：笑气吸入的镇痛效果次于腰硬联合麻醉，但操作简单、经济实惠，值得基层医院推广；腰硬联合麻醉镇痛起效迅速、效果最佳，可作为分娩镇痛的首选方法。

Clinical studies CSEA labor analgesia with nitrous oxide inhalation

Objective:To analyze the clinical effect of epidural anesthesia and nitrous oxide inhalation analgesia and its impact on maternal and newborn. Methods:A retrospective analysis of 294 cases of maternal epidural group of 92 cases in which the use of epidural anesthesia; 92 cases of inhalation of nitrous oxide group using mixed gas containing 50% nitrous oxide and 50% oxygen; the control group did not use any methods of analgesia. Analgesic effect was observed in each group. Results:epidural group and nitrous oxide analgesia group were significantly better than the control group, and the group of spinal epidural analgesia cervix (T3) was significantly higher than the intensity of the contractions nitrous oxide group, the active phase of the first stage of labor in pregnant women short;mode of delivery epidural group and nitrous oxide were significantly better than the control group;postpartum hemorrhage , neonatal adverse reactions, Apgar score three groups no significant difference. Conclusion:nitrous oxide inhalation analgesia inferior to epidural anesthesia, but simple, affordable, primary hospitals should be popularized; CSEA rapid onset of analgesia, the best results can be used as the preferred method of analgesia .
