摘要 产后出血(postpartum heamorrhage,PPH)是选择性剖宫产产后常见并发症,也是产妇首位死亡原因,通常是指剖宫产胎儿娩出后24 h内出血量超过1 000 mL,可由多种原因引起,其中最主要的是子宫收缩乏力,早期预防与积极治疗成为降低PPH死亡率的关键[1]。目前临床上通常采用产前预防性给予宫缩剂,首选药物为缩宫素(oxytocin),其通过调节钙离子促进宫缩[2],分娩时宫颈和阴道受到挤压可以通过神经反射引起下丘脑的核团分泌缩宫素,刺激子宫平滑肌从底部至颈部节律性收缩,但不是引起子宫收缩的决定因素,受情绪等心理因素影响明显[4],且其半衰期短,受体数量有限,不能长时间大剂量应用,在一些情况下影响预防效果[3]。
