分娩时间和严重产后出血的相关性分析

目的探讨分娩时间和严重产后出血的相关性。方法选取本院2017年8月-2019年6月严重产后出血者113例为观察组,同期正常分娩者113例为对照组,收集病例资料(年龄、体质量指数、分娩时间、巨大儿、流产史、初产妇、孕期贫血、产前宫缩剂、产后出血情况),分析分娩时间和严重产后出血的相关性。结果观察组第一产程、第二产程、第三产程长于对照组,差异均有统计学意义(P<0.05)。年龄、BMI、分娩时间、巨大儿、孕期贫血、引产、产前宫缩剂均是严重产后出血的影响因素(P<0.05)。分娩时间和严重产后出血存在正相关(r=0.473,P<0.05)。结论分娩时间越长,严重产后出血风险越大。

Correlation Analysis Between Delivery Time and Serious Postpartum Hemorrhage

Objective To investigate correlation analysis between delivery time and serious postpartum hemorrhage.Methods 113 patients with serious postpartum hemorrhage were selected in hospital from August 2017 to June 2019 as observation group.113 patients with normal delivery were selected at same period as control group.Data(age,body mass index,delivery time,macrosomia,abortion history,primipara,anemia during pregnancy,prenatal contractions,postpartum hemorrhage)were collected.Correlation between delivery time and serious postpartum hemorrhage was analyzed.Results The first stage of labor,second stage of labor,third stage of labor in observation group were longer than control group.Differences were statistically significant(P<0.05).Age,BMI,delivery time,macrosomia,anemia during pregnancy,induction of labor,uterine contractions before delivery were influencing factors of severe postpartum hemorrhage(P<0.05).Delivery time was significant positive correlation with severe postpartum hemorrhage(r=0.473,P<0.05).Conclusion The longer delivery time,the greater risk of serious postpartum hemorrhage.
