Case Report Fetomaternal Hemorrhage following Placement of an Intrauterine Pressure Catheter: Report of a New Association

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Fetomaternal hemorrhage (FMH) can be associated with significant perinatal mortality. Our review of the literature did not identify any cases of FMH following placement of an intrauterine pressure catheter (IUPC). In our case, an IUPC was inserted in a patient undergoing induction of labor at term. Fetal bradycardia ensued shortly after placement, warranting an emergent cesarean delivery. Severe neonatal anemia was identified, and evaluation ofmaternal bloodwas consistent withmassive FMH.This is the first reported association between FMH and IUPC placement. If this relationship is validated in future reports, appropriate changes in clinical practice may be warranted. Fetomaternal hemorrhage (FMH) occurs when fetal blood passes into thematernal circulation at any stage of pregnancy. FMH can be associated with significant perinatal mortality, primarily related to severe anemia and hypotension in the fetus or newborn. A number of predisposing factors have been identified. Our review of the literature did not identify any cases of FMH following insertion of an intrauterine pressure catheter (IUPC), a potential new association that w
