目的探讨产后出血的原因及预防措施。方法将590例产妇随机分为实验组A组和对照组B组,观察、记录产妇第三产程时间、出血量等,在产妇第三产程应用缩宫素及米索前列醇,预防产后出血的发生。结果A组产妇产后出血发生率明显低于B组。A组第三产程时间缩短,胎盘剥离娩出完整,有9例需宫腔探查;B组有16例胎盘剥离不完整,需宫腔探查。结论子宫收缩乏力、胎盘滞留、软产道撕裂、产程延长、精神过度紧张是产后出血的主要危险因素,在第三产程应用缩宫素和米索前列醇可以减少或预防产后出血的发生。
Objective To investigate the causes and preventive measures of postpartum hemorrhage. Methods 590 pregnant women were randomly divided into experimental group A and control group B, observed and recorded the third trimester of maternal time, bleeding and so on, in the third trimester of maternal application of oxytocin and misoprostol to prevent postpartum hemorrhage occur. Results The incidence of postpartum hemorrhage in group A was significantly lower than that in group B. In group A, the time of the third stage of labor was shortened, placental abruption was delivered completely, and in 9 cases, uterine exploration was needed. In group B, there were 16 cases with incomplete placental dissection and uterine exploration. Conclusion Uterine atony, placenta accreta, tearing of soft birth canal, prolonged labor and over-stress are the main risk factors of postpartum hemorrhage. Oxytocin and misoprostol can reduce or prevent postpartum hemorrhage in the third stage of labor.
