SI和DBP对女性产后出血的风险预测效果

Effect of SI and DBP on risk prediction of postpartum hemorrhage in women

目的考察休克指数(shock index,SI)和舒张压(diastolic blood pressure,DBP)对女性产后出血的风险预测效果。方法选取2016年1月~2018年12月在我院行产检并分娩的320例产后出血孕妇作为研究组,另外选取同期进行正常分娩的健康孕妇240例作为对照组,比较两组患者的一般临床资料、血红蛋白(hemoglobin,Hb)、舒张压(diastolic blood pressure,DBP)、收缩压(systolic blood pressure,SBP)、心率(heart rate,HR)及休克指数(shock index,SI),并采用Ordinal逻辑回归分析各参数对产后出血的风险预警。结果两组患者在年龄、孕周、BMI及新生儿体重相比,差异无统计学意义(P>0.05),而孕次相比,差异具有统计学意义(P<0.05);与对照组产后24 h相比,研究组产后24 h患者的DBP、SBP及Hb均显著降低,而HR和SI显著升高(P<0.05);与对照组产前相比,产后24 h患者的SBP、HR及SI显著降低(P<0.05);与研究组产前相比,产后24 h患者的DBP、SBP、HR及Hb均显著降低,而SI显著升高,差异具有统计学意义(P<0.05);Ordinal逻辑回归分析结果显示,休克指数和舒张压对产后出血具有预警作用(P<0.05)。结论休克指数和舒张压可作为评估女性产后出血的风险预测指标,临床应密切监护。

Objective To investigate the effect of shock index(SI)and diastolic blood pressure(DBP)on the risk prediction of postpartum hemorrhage in women.Methods A total of 320 pregnant women with postpartum hemorrhage who underwent prenatal check-up and delivery in our hospital from January 2016 to December 2018 were selected as the study group,and 240 healthy pregnant women who underwent normal delivery during the same period were selected as the control group.The general clinical data,hemoglobin(Hb),diastolic blood pressure(DBP),systolic blood pressure(SBP),heart rate(HR),and shock index(shock index,SI)between two groups were compared.And Ordinal logic regression analysis was used to analyze various parameters for early warning of the risk of postpartum hemorrhage.Results There was no significant difference in age,gestational week,BMI and neonatal weight between the two groups(P>0.05).There were significant differences in the number of pregnancies between two groups(P<0.05).Compared with that of the control groupat 24 h postpartum,DBP,SBP,and Hb in the study group was significantly reduced,while HR and SI was significantly increased(P<0.05).The SBP,HR and SI was significantly lower in the control group at 24 h postpartum than that prenatal(P<0.05).Compared with that prenatal,the DBP,SBP,HR and Hb of the study group at 24 h postpartum was significantly reduced,while the SI was significantly increased,and the difference was statistically significant(P<0.05).Ordinal logistic regression analysis showed that shock index and diastolic blood pressure had early warning effect on postpartum hemorrhage(P<0.05).Conclusion Shock index and diastolic blood pressure can be used as predictors of the risk of postpartum hemorrhage in women,and they should be closely monitored clinically.
