目的：观察卡孕栓联合缩宫素预防剖宫产产后出血的临床效果。方法：选择有产后出血高危因素的剖宫产者120例,60例为实验组(卡孕栓+缩宫素)，60例为对照组(缩宫素组)。实验组在术中胎儿娩出后立即给予卡孕栓1m g舌下含服,并子宫肌壁内注射缩宫素针20U；对照组常规子宫肌壁内注射缩宫素针20U，以上两组观察术中及术后24 h出血量。结果：实验组在术中及术后24 h出血量明显减少,两组差异有统计学意义(P<0.05)。结论：卡孕栓联合缩宫素能有效促进子宫收缩，减少剖宫产术后出血量,预防产后出血，效果优于单独使用缩宫素。用药安全、方便，疗效满意，值得临床推广。“,”Objective To observe the Carprost joint oxytocin prevent postpartum hemorrhage clinical results.Methods Risk factors for postpartum hemorrhage cesarean section 120 cases, 60 cases of the experimental group (Carprost + oxytocin), 60 cases in the control group (oxytocin group). Given the experimental group during surgery immediately after the baby is delivered Carprost 1mg sublingual and contraction within the muscle wall of the uterus injection needle oxytocin 20U; 20U needle injection of oxytocin within the control group routine uterine muscle wall, more than two intraoperative and 24 h after the bleeding.Results The experimental group and 24 h after surgery significantly reduced the amount of bleeding during surgery, the difference was statistically significant (P <0.05).Conclusion Carprost joint oxytocin can promote uterine contractions, reducing the amount of bleeding after cesarean section to prevent postpartum hemorrhage, better than oxytocin alone. Drug safety, convenience, results were satisfactory, worthy of promotion.
