Pre-delivery fibrinogen level is a predictor for severity of placental abruption

OBJECTIVE: To determine pre-delivery fibrinogen levels in predicting adverse maternal or neonatal outcomes in patients with placental abruption. MATERIALS AND METHOD: We conducted a retrospective study of all women admitted for placental abruption between January 2012 and May 2018. Postpartum hemorrhage (PPH), disseminated intravascular coagulation (DIC), massive blood transfusion and hospitalization in intensive care unit parameters were evaluated for maternal outcomes. For the neonatal outcomes, the 5th minute APGAR score, umbilical artery pH and stillbirth were evaluated. RESULTS: The mean predelivery fibrinogen levels were 221.3 ± 111.6 mg/dL. In multivariate logistic regression analysis, fibrinogen level was determined as an independent indicator for PPH, red cell concentrate (RCC) and fresh frozen plasma (FFP) transfusion. When fibrinogen levels decreased below 130 mg/dL, the risk of PPH increased and when fibrinogen levels decreased below 100 mg/dL, the risk of overt DİC and also the risk of red cell concentrate and fresh frozen plasma transfusion increased. In terms of the fetal results, there may be adverse neonatal outcomes when fibrinogen levels are below 250 mg/dL. CONCLUSION: Predelivery fibrinogen levels are good indicators for predicting adverse maternal outcomes in placental abruption cases. In addition, fibrinogen levels might be a guide for management of placental abruption cases.
