摘要/Abstract

摘要： 目的分析产后出血预测评分与产妇凝血指标的相关性,以及出血预测评分对阴道分娩产后出血的预测效能。方法采用回顾性研究,纳入2021年1月—2022年12月河南科技大学第二附属医院收治的136例阴道分娩产妇,根据产后出血情况,将合并产后出血的36例患者列为病例组,其余100例列为对照组,比较两组患者的产后出血预测评分及凝血指标,经Spearman相关性系数验证产后出血预测评分结果与凝血指标的相关性,依据实际出血情况,验证产后出血预测评分、各凝血指标对产后出血的预测效能。结果病例组患者的产后出血预测评分为（7.33±2.46）分,D-二聚体（D-D）为（2.62±0.41）mg/L,均高于对照组[（6.14±2.06）分、（2.17±0.45）mg/L],纤维蛋白原（FIB）为（4.42±1.25）g/L,低于对照组（5.23±1.16）g/L;活化部分凝血活酶时间（APTT）为（37.44±10.25）s,凝血酶原时间（PT）为（15.45±4.12）s,凝血酶时间（TT）为（16.77±4.25）s,均高于对照组[（30.11±10.12）s、（12.49±4.11）s、（13.34±4.18）s],差异具有统计学意义（P<0.05）。经Spearman相关性系数分析,产后出血预测评分与经阴道分娩产妇的D-D、APTT、PT、TT呈正相关,与FIB呈负相关。通过绘制受试者工作特征曲线（ROC）后得知,产后出血预测评分及凝血指标对产后出血均有一定预测价值,但产后出血预测评分的AUC值大于各凝血指标。结论产后出血预测评分与产妇凝血功能指标呈正相关,将产后出血预测评分与凝血指标检测相结合能实现对产后出血的早期识别及诊断。

Abstract: Objective To analyze the correlation between postpartum bleeding prediction score and maternal blood coagulation index and the prediction efficiency of postpartum bleeding in vaginal delivery．Methods This is a retrospective study．The cases were included from January 2021 to December 2022．The subjects of the study were 136 vaginal delivery mothers． According to the delivery situation,36 patients with postpartum bleeding were included in the case group,and the rest 100 patients were included in the control group．The postpartum bleeding prediction score and coagulation indicators of the two groups were compared．The correlation between postpartum bleeding prediction score and coagulation indicators was verified by Spearman correlation coefficient．According to the actual bleeding situation,verify the predictive score for postpartum bleeding and the diagnostic efficacy of various coagulation indicators on postpartum bleeding．Results According to the test,the predictive score for postpartum bleeding in the case group was（7.33±2.46）,D-dimer（D-D）was（2.62±0.41）mg/L,which were higher than those in the control group [（6.14±2.06）,（2.17±0.45）mg/L]．Fibrinogen（FIB）was（4.42±1.25）g/L,lower than the control group（5.23±1.16）g/L,activated partial thromboplastin time（APTT）was（37.44±10.25）s,prothrombin time（PT）was（15.45±4.12）s,and thrombin time（TT）was（16.77±4.25）s．Compared with the control group [（30.11±10.12）s,（12.49±4.11）s,and（13.34±4.18）s）],the above indicators were all higher（P<0.05）．Through Spearman correlation coefficient analysis,the predictive score of postpartum bleeding was positively correlated with the D-D,APTT,PT,TT,negatively correlated with the FIB of the parturient who delivered through vagina．After drawing the ROC curve,it was found that both the postpartum hemorrhage prediction score and coagulation indicators had certain predictive value for postpartum hemorrhage,but the AUC value of the postpartum hemorrhage prediction score was greater than each coagulation indicator．Conclusions The prediction score of postpartum bleeding is positively correlated with the coagulation function indicators of the parturient,combining the score and indicators can achieve early identification and diagnosis of postpartum bleeding．
