为探讨产程活跃期静注安定对产后出血的影响。１９９３年３月～１９９４年３月本文对单一用安定后阴道分娩的１３０例（安定组）进行了回顾性分析，按１∶１选配同期联合应用安定＋催产素（安催组）和未用任何药物经阴道分娩（对照组）各１３０例作为配比对照。结果：安定组平均产后出血量分别比安催组和对照组多４３ｍｌ和５２ｍｌ（Ｐ＜００５），安催组和对照组无显著差异。提示：单一静注安定可使产后出血量增多。故主张在应用安定催产的同时静点催产素，以减少安定增加产后出血量的危险 To investigate the active phase of labor during intravenous stability of postpartum hemorrhage. From March 1993 to March 1994, we retrospectively analyzed 130 single diazepam (diazepam) patients treated with diazepam alone. The patients were treated with diazepam and oxytocin at a ratio of 1: With any drug vaginal delivery (control group) of 130 cases as a control. Results: The mean postpartum hemorrhage volume in diazepam group was 43ml and 52ml more than that in safety group and control group, respectively (P <005). There was no significant difference between safety group and control group. Tip: A single intravenous stability can increase the amount of postpartum hemorrhage. It is advocated in the application of stable oxytocin oxytocin to reduce the risk of increased postpartum hemorrhage
