The Relationship between Fluid Resuscitation and the Risk of Disseminated In-travascular Coagulation in Postpartum Hemorrhage Patients / 实用妇产科杂志

ABSTRACT

Objective:To explore the relationship between fluid dosage during fluid resuscitation and the risk of disseminated intravascular coagulation(DIC)in postpartum hemorrhage patients.Methods:A retrospective case-control study was conducted on patients who were admitted to Shenyang Women′s and Children′s Hospital between January 1,2016,and December 31,2022 with postpartum hemorrhage≥1000 ml.The patients were di-vided into two groups according to pregnancy-corrected ISTH scoresgroup with ISTH score＞26;group with ISTH score≤26.The two groups were matched for 1 ∶ 4 propensity scores and the differences between ratio of crystalloid solution to bleeding volume;ratio of colloidal solution to bleeding volume;ratio of red blood cell infusion to bleeding volume;ratio of plasma infusion to bleeding volume and peak decrease of fibrinogen in the two groups were compared.And analyze the relationship between various observation indicators and the occurrence of DIC.Results:The ROC area under the curve(AUC)values for predicting of the ratio of crystalloid solution to bleeding volume,ratio of colloidal solution to bleeding volume,the peak decrease in fibrinogen,ratio of red blood cell infu-sion to bleeding volume,ratio of plasma infusion to bleeding volume were 0.670(95%CI 0.589-0.751),0.532(95%CI 0.440-0.623),0.771(95%CI 0.706-0.837),0.530(95%CI 0.439-0.621),and 0.563(95%CI 0.473-0.653),the optimal cut off values were 1.23,0.29,0.77,0.48,0.24.The ratio of crystalloid solution to bleeding volume and the peak decrease in fibrinogen were positively correlated with the occurrence of DIC after postpartum hemorrhage,the OR values were 0.256(95%CI 0.111-0.590)and 0.074(95%CI 0.024-0.228).There was no correlation between the ratio of colloidal solution to bleeding volume,the ratio of red blood cell infusion to bleeding volume,the ratio of plasma infusion to bleeding volume and the occurrence of DIC after postpartum hemorrhage.Conclusions:The infusion volume of crystalloid solution is related to the occurrence of DIC,and restrictive fluid resuscitation can reduce the incidence of DIC.Additionally,to lower the risk of DIC,fibrin-ogen or cold precipitation should be rapidly supplied when the decrease of fibrinogen exceeded 0.77 g/L to re-duce the risk of postpartum hemorrhage DIC.
