BackgroundWomen with placenta increta (PI) and placenta percreta (PP) are at high risk of obstetric hemorrhage; however, the severity of hemorrhage and perioperative morbidity may differ according to the degree of placental invasion. We sought to compare blood component usage and perioperative morbidity between women with PI versus PP undergoing cesarean hysterectomy (CH).Study Design And MethodsWe identified 77 women who underwent CH for PI or PP from the NICHD MFMU Network Cesarean Registry, which sourced data from 19 centers from 1999 to 2002. We examined demographic, obstetric, and surgical data and rates of transfusion and perioperative morbidity. We performed statistical tests for between-group analyses; p values less than 0.05 were significant.ResultsRates of intraoperative or postoperative red blood cell (RBC) transfusion were similar between groups (PI 84% vs. PP 88%; p=0.7). We observed no between-group differences in rates of fresh-frozen plasma (FFP) transfusion (intraoperative FFP-PI 30% vs. PP 41%; p=0.3; postoperative FFP-PI 28% vs. PP 18%; p=0.4) or platelet (PLT) transfusion (intraoperative PLTs-PI 14% vs. PP 29%; p=0.2; postoperative PLTs-PI 9% vs. PP 9%; p=1.0). Among the morbidities, a higher proportion of PP women underwent cystotomy (PI 14% vs. PP 38%; p=0.02) and postoperative mechanical ventilation (PI 14% vs. PP 35%; p=0.03).ConclusionRates of intraoperative RBC, FFP, and PLT transfusion are similar for PI and PP women, and perioperative outcomes are worse for PP women. We suggest the same mobilization transfusion medicine support for both groups, including blood ordering (type and cross-match for CH) and availability of emergency blood protocols including fibrinogen-containing preparations.© 2013 American Association of Blood Banks.
