两种常用分娩镇痛法临床疗效的比较研究

Comparative study on clinical efficacy of two common labor analgesia methods

目的比较两种常用分娩镇痛法的临床疗效。方法选取2010年10月～2013年4月在本院住院分娩的产妇50例，采用随机对照法将其分为硬膜外自控镇痛组（PCEA组）和一氧化二氮吸人镇痛组（IA组）．每组各25例。比较两组产妇的镇痛效果、剖宫产率、总产程时间及新生儿Apgar评分。结果PCEA组镇痛有效率为96．0％，IA组镇痛有效率为64．0％，PCEA组镇痛效果显著优于IA组，差异有统计学意义（P〈0．05）;PCEA组剖宫产率及总产程时间均显著低于IA组，差异有统计学意义（P〈0．05）；两组新生儿Apgar评分比较，差异无统计学意义（P〉0．05）。结论硬膜外白控镇痛较一氧化二氮吸入镇痛临床效果明显，剖宫产率低，总产程时间短，且对新生儿无明显副作用，值得在临床应用和推广。

Objective To compare the clinical efficacy of two commonly used labor analgesia methods. Methods Fifty puerperae who delivered in our hospital between October 2010 to April 2013 were selected and divided into the patient controlled epidural analgesia group （PCEA group） and the nitrous oxide inhalation analgesia group （IA group） using the randomized control method,with 25 cases in each group.The analgesic effect,cesarean section rates,total labor time and neonate Apgar scores of the two groups were compared. Results The analgesic effective rate of the PCEA group was 96.0% and that of the IA group was 64.0%;The PCEA group had better analgesic effect than the IA.group, with statistically significant difference （P〈0.05）.The PCEA group had significantly lower cesarean section rate and shorter total labor time than the IA group,with statistically significant differences （P〈0.05）.The two groups did not have statistically significant difference in the neonate Apgar score （P〉0.05）. Conclusion Epidural controlled analgesia has more significant clinical effect,lower cesarean section rate and shorter total labor time than nitrous oxide inhalation analgesia and causes no significant side effects to the neonate,thereby worthy of clinical application and promotion.
