目的探讨产程中缩宫素应用的最佳时机。方法选择同一时期符合条件病人180例,分3组(各60例)进行比较分析。第1组:无分娩先兆,行缩宫素静脉滴注从诱发宫缩至胎儿娩出。第两组:宫口开3cm时行缩宫素静脉滴注。第3组为自然分娩组。结果第1组缩宫素用量大,产后出血量多,头位难产率高,与第两组比较差异有统计学意义(P<0.01)。第3组与第两组比较,头位难产率明显高于第两组。结论产程中宫口开3cm时行缩宫素静脉滴注时机最佳。
Objective To investigate the optimal timing of oxytocin administration during labor. Methods 180 cases of eligible patients were selected during the same period, divided into 3 groups (60 cases each) for comparative analysis. Group 1: no precursor atrophy, line oxytocin intravenous infusion induced contractions from the fetus to deliver. The second group: 3cm open cervix when oxytocin intravenous infusion. The third group for the natural childbirth group. Results The first group had a large amount of oxytocin, more postpartum hemorrhage and high head dystocia rate, which was significantly different from the second group (P <0.01). Group 3 compared with the second group, head dystocia rate was significantly higher than the second group. Conclusion Otorhinolaryngitis 3cm open oxytocin intravenous infusion of the best timing.
