Abstract
Issue in cases of severe postpartum hemorrhage. METHODS: We reviewed data from all patients diagnosed with severe postpartum hemorrhage during a 4-year period (2006–2009). Patients who were treated with sulprostone and required transfusion within 6 hours of delivery were included in the study and were divided into 2 groups according to their response to sulprostone: bleeding controlled with sulprostone alone (sulprostone group) and bleeding requiring an additional advanced interventional procedure including arterial angiographic embolization and/or surgical procedures (arterial ligation, B-Lynch suture, or hysterectomy; intervention group). The requirement or no requirement for advanced procedures constituted the primary end point of the study. Propensity scoring was used to assess the effect of a high FFP:RBC ratio on bleeding control. RESULTS: Among 12,226 deliveries during the study period, 142 (1.1%) were complicated by severe postpartum hemorrhage. Bleeding was controlled with sulprostone alone in 90 patients (63%). Advanced interventional procedures were required for 52 patients (37%). Forty-one patients were transfused with both RBCs and FFP. The FFP:RBC ratio increased over the study period (P < 0.001), from 1:1.8 at the start to 1:1.1 at the end of the study period. After propensity score modeling (inverse probability of treatment weighting), a high FFP:RBC ratio was associated with lower odds for advanced interventional procedures (odds ratio [95% confidence interval], 1.25 [1.07–1.47]; P = 0.008). There were no deaths, severe organ dysfunction, or other complications as a consequence of severe postpartum hemorrhage. CONCLUSIONS: In this retrospective study, a higher FFP:RBC ratio was associated with a lower requirement for advanced interventional procedures in the setting of postpartum hemorrhage. The benefits of transfusion using a higher FFP:RBC ratio should be confirmed by randomized-controlled trials....
