ABSTRACT

Background: The association between coagulation profile and postpartum hemorrhage (PH) is still debated.
Objective: To determine the association between hemostatic profile and PH in women with cesarean operation (CO).
Methods: We included 92 patients with PH (cases) and 184 without (controls), patients were attended during 2014, at one hospital of the Instituto Mexicano del Seguro Social in Mérida, Yucatán. Demographic, clinical and laboratory data including prothrombin time (PT), activated partial thromboplastin time (aPTT), platelet count (PLC), and fibrinogen concentration were compared among cases and controls using a binary logistic regression model (LRM), from which odd ratios (OR), and 95% confidence intervals (95% CI), were obtained.
Results: According to the bivariate comparison, in the LRM categorical data such as parity, any type of hypertensive comorbidity, type of anesthesia, and categorized aPTT (‹ 38 vs. ≥ 38 seconds), and one continuous variable (gestational age) were included. Having some hypertensive comorbidity (OR 3.55, 95% CI: 1.95-6.47), type of anesthesia (regional anesthesia, OR 0.27, 95% CI: 0.13-0.55) and aPTT (‹ 38 seconds, OR 0.26, 95% CI: 0.10-0.66) were all statistically significant. Categorized PT, platelet count and fibrinogen concentration, were not statistically significant.
Conclusions: In this sample, having some hypertensive comorbidity increased risk of PH more than three times, while regional anesthesia and aPTT ‹ 38 seconds reduced risk in 73% and 74%, respectively. Neither platelet count, nor fibrinogen concentration, or the PT categories modified risk of PH.
