RESUMO
Objective To investigate the significance of detection of blood coagulation and fibrinolytic indexes before and after delivery.Methods 212 cases in the postpartum hemorrhage group(bleeding amount ≥500 mL)and 235 cases in the normal deliver-y group were retrospectively analyzed.The prothrombin time(PT),international normalized ratio(PT-INR),activated partial throm-boplastin time(APTT),thrombin time(TT),fibrinogen(FIB),D-dimer(DD),blood platelets(PLT)and hemoglobin(HB)were de-tected before delivery and at 72 h after delivery.85 women with the physical examination were selected as the healthy group.Results Before delivery,PT/PT-INR,APTT,TT,PLT and HB in the normal delivery group were lower than those in the healthy group, while FIB and DD were higher than those in the healthy group;PT/PT-INR,APTT,TT and DD in the postpartum hemorrhage group were higher than those in the normal delivery group,while FIB and PLT were lower than those in the normal delivery group. At 72 h after delivery,there was no statistically significant differences in PT/PT-INR,APTT,TT and DD between the normal de-livery group and the healthy group(P >0.05),but FIB was higher than that in the healthy group;PT/PT-INR,APTT,TT and DD in the postpartum hemorrhage group were higher than those in the normal delivery group,while FIB,PLT and HB were lower than those in the normal delivery group.Conclusion Dynamically monitoring the change of the blood coagulation and fibrinolysis indexes before and after delivery has important significance in preventing postpartum hemorrhage and thrombosis.
