摘要
目的探讨笑气吸入在分娩镇痛中的效果和对母儿的影响。方法对136例产妇在产程中给予吸入50%氧化亚氮(笑气)和50%氧气组成的混合气体实行镇痛分娩(研究组),另选择200例产妇在产程中不给予笑气吸入(对照组),观察两组产妇疼痛的程度、产程时间、分娩方式、羊水情况、产后出血量和新生儿Apgar评分等。结果研究组的镇痛有效率和自然分娩率高于对照组;总产程时间短于对照组,两组比较差异有显著性(P<0.05)。羊水污染、新生儿窒息率和产后出血,两组比较差异无显著性(P>0.05)。结论吸入50%氧化亚氮(笑气)和50%氧气组成的混合气体用于分娩镇痛可有效地缓解分娩疼痛,缩短产程时间,对母儿无不良影响,是一种安全、有效、简便的镇痛方法。
Objective : To investigate the efficiency of inhaling nitrous oxide for labor pain relief and its effects on maternal and fetus. Methods:A total of 136 cases of pregnant women were provided with nitrous oxide premixed with oxygen (50 % :50 % )( study group) ; Another 200 cases were not provided with 50% nitrous oxide in oxygen( control group).Two groups were compared on following indices: the degree of labor pains, delivery process, delivery ways, meconium stained of ammiotic fluid, rate of postpartum hemorrhage and neonatal Apgar scores. Results: The efficiency of relieving labor pain in study group and the rate of normal labor were higher than cpmtrol gr5oup;delivery poreess in study group was shorter than control group ( P 〈 0.05) ; There were no significant differences in meconlum stained of anmiotic fluid, neonatal Apgar scores and rate of postpartum hemorrhage between two groups( P 〉 0.05 ). Conclusion:As a safe, effective and easy method, the inhalation of nitrous oxide premixed with oxygen (50% :50% ) was effective for relieving labor pain and results in a short delivery process.
