休克指数与阴道分娩产后出血量及失血性休克发生率的关系

Relationship between shock index and postpartum blood loss and incidence of hemorrhagic shock in vaginal delivery

目的:分析休克指数与阴道分娩产后出血量及失血性休克发生率的关系。方法:选择2017年6月至2019年6月本院收治的阴道分娩产后出血患者80例为研究组,以同期本院健康孕产妇80例为对照组。比较两组的一般资料、休克指数,分析休克指数与产后出血量及失血性休克发生率的关系。结果:研究组产后心率、休克指数高于对照组,收缩压(SBP)、舒张压(DBP)低于对照组(均P<0.05)。研究组休克指数<0.9的产妇32例(40%)、休克指数≥0.9的产妇48例(60%),休克指数≥0.9的产妇产后出血量及失血性休克发生率均高于休克指数<0.9的产妇(均P<0.05)。结论:休克指数升高会导致阴道分娩产妇产后出血量及失血性休克发生率增高,可作为预测产后出血的重要指标。

Objective:To analysis the relationship between shock index,postpartum blood loss and the incidence of hemorrhagic shock in vaginal delivery.Methods:Eighty patients with postpartum hemorrhage from vaginal birth admitted to our hospital between June 2017 and June 2019 were included as the study group,and a contemporary cohort of 80 healthy pregnant women were included as the control group.The general data and shock index of the two groups were compared,and the relationship between shock index,postpartum blood loss and the incidence of hemorrhagic shock were analyzed.Results:The study group showed higher postpartum heart rate and shock index(P<0.05),and lower systolic blood pressure(SBP)and diastolic blood pressure(DBP)(P<0.05),compared with the control group.In the study group,there were 32 women(40%)with a shock index of less than 0.9,and 48(60%)with a shock index≥0.9.The postpartum blood loss and the incidence of hemorrhagic shock were higher in women with shock index≥0.9 than in those with shock index<0.9(P<0.05).Conclusion:Elevated shock index can lead to increased postpartum blood loss and incidence of hemorrhagic shock in vaginal births,and can be used as an important indicator to predict postpartum hemorrhage.
