Maternal and Fetal Outcomes in Disseminated Intravascular Coagulation Cases Associated with Pregnancy Complications

Abstract

Background: The relationship between the pregnancy modified DIC score, which is applied in obstetric conditions where the risk of disseminated intravascular coagulation is high, and underlying disease, as well as its effect on the prognosis, was investigated.

Methods: Those with a DIC score ≥ 26 from obstetric conditions, such as obstetric bleeding, placental abruption, or preeclampsia/HELLP syndrome, which are at high risk of developing DIC, were included in the study. These patients were compared in terms of laboratory results, maternal morbidity/mortality, and neonatal outcomes, according to the underlying disease.

Results: The DIC score was ≥ 26 in 224 of 154,233 deliveries in our center, and the incidence was 0.14%. In the preeclampsia/HELLP syndrome group, the platelet count and prothrombin time were lower, and the fibrinogen level was higher than those of the obstetric hemorrhage and placental abruption groups. In addition, the rates of blood transfusion and hysterectomy were lower in women who developed DIC due to pre-eclampsia/HELLP syndrome than in those with obstetric hemorrhage.

Conclusions: Considering the underlying disease is an important factor in predicting prognosis, when using the new pregnancy modified diagnostic scores for DIC diagnosis.
