目的探讨无痛分娩法用于分娩镇痛的临床疗效及对母婴结局的影响。方法选择2015年7月—2016年9月妇产科分娩的无内科及产科并发症的产妇80例,根据产妇的意愿随机分为两组,不采用任何止痛措施的产妇40例为对照组,要求止痛分娩的产妇40例为观察组,观察组在对照组的基础上实施硬膜外麻醉分娩。比较两组三个阶段的产程时间、镇痛效果及母婴结局。产程时间比较采用t检验,母婴结局及镇痛效果比较采用χ2检验,P<0.05为差异有统计学意义。结果对照组第一、二、三各产程时间分别为[(3.26±0.64)、(0.89±0.41)、(0.20±0.05)h]、剖宫产率25.00%明显高于观察组[(2.35±0.23)、(0.67±0.23)、(0.14±0.04)h,7.50%],差异有统计学意义(均P<0.05);对照组新生儿窒息及产后出血发生率分别为12.50%、15.00%,与观察组(7.50%、12.50%)相比,差异无统计学意义(均P>0.05);对照组镇痛效果良好率17.50%低于观察组97.50%,比较差异有统计学意义(P<0.05)。结论对产妇实施无痛分娩可有效缩短生产时间,降低剖宫产率,减轻产妇疼痛,改善母婴结局。
Objective To investigate the clinical efficacy of painless labor for labor analgesia and its effect on maternal and infant outcomes. Methods 80 cases of obstetrics and gynecology obstetric complications were selected from July 2015 to September 2016. They were randomly divided into two groups according to the wishes of the mothers and 40 maternal without any analgesic measures. 40 cases requiring analgesia and childbirth for the observation group, the observation group in the control group based on the implementation of epidural anesthesia childbirth. The two groups of three stages of labor time, analgesia and maternal and child outcomes. Comparison of labor time t-test, maternal and child outcomes and analgesic effect using χ2 test, P <0.05 for the difference was statistically significant. Results The first, second and third labor hours in the control group were (3.26 ± 0.64), (0.89 ± 0.41) and (0.20 ± 0.05) h respectively, and the cesarean section rate was 25.00%, significantly higher than that in the observation group [(2.35 ± 0.23), (0.67 ± 0.23), (0.14 ± 0.04) h and 7.50%, respectively (all P <0.05). The incidences of neonatal asphyxia and postpartum hemorrhage in the control group were 12.50% and 15.00%, respectively Compared with the observation group (7.50%, 12.50%), the difference was not statistically significant (all P> 0.05). The good rate of analgesia in the control group was 17.50% lower than that in the observation group (97.50%), the difference was statistically significant (P < 0.05). Conclusion The painless childbirth delivery can shorten the production time, reduce the cesarean section rate, reduce the maternal pain and improve the maternal and infant outcomes.
