目的:探讨刮宫术次数与产后出血发生率及出血量的关系。方法:选择产前检查正常且头胎足月阴道分娩2025例,按以往不同刮宫次数(0～7次)分为8组,对比观察各组病例产后出血发生率及平均出血量,分别与刮宫次数进行积差相关分析。结果:产前刮宫次数与产后出血发生率的相关系数为0.909,与产后出血量的相关系数为0.730,提示刮宫次数与产后出血发生率及出血量均呈显著正相关(P<0.05)。结论:应尽可能减少产前刮宫次数,避免引发产后出血。
Objective: To investigate the relationship between the number of curettage and the incidence of postpartum hemorrhage and bleeding. Methods: 2025 cases with normal prenatal and full-term vaginal delivery were selected and divided into 8 groups according to the number of previous curettage (0 ~ 7 times). The incidence of postpartum hemorrhage and mean amount of bleeding in each group were compared with that of curettage The number of times to carry out correlation analysis. Results: The correlation coefficient between the number of prenatal curettage and postpartum hemorrhage was 0.909, and the correlation coefficient with postpartum hemorrhage was 0.730, suggesting that there was a significant positive correlation between the number of curettage and the incidence of postpartum hemorrhage and bleeding (P <0.05). Conclusion: The number of prenatal curettage should be reduced as much as possible to avoid postpartum hemorrhage.
