Abstract
Fetomaternal hemorrhage (FMH) result into severe, life-threatening fetal anemia and cause intrauterine death of the fetus. It is tough for an early diagnosis of FMH before pregnancy and few authors reported FMH in a twin pregnancy. Therefore, we reported a case of massive FMH. The patient felt a decrease in fetal movements at 33+5 gestational weeks. Cardiotocography showed sinusoidal heart rate patterns in one fetus. The fetal hemoglobin level in maternal blood was 6.4% (normal range for single pregnancy, 0.0%-2.0%). Since the patient was diagnosed with fetal distress, cesarean section was performed and both babies delivered to receive neonatal treatment. Severe anemia was apparent in both neonates, based on red blood cell count, hemoglobin concentration, and hematocrit of 0.75 × 1012/L and 0.61 × 1012/L, 2.8 g/dL and 2.4 g/dL, and 10.0% and 8.4%, respectively. The neonates were admitted to the intensive care unit for prematurity care and presently are well. In our experience, an early diagnosis of FMH contributed to saving fetus. Obstetricians should highlight fetal movements counting to every patient. Once massive FMH occurs in monochorionic twins, both fetuses may develop severe anemia and require emergency intervention.

Evaluation of Automatic Blood Analyzer as Screening Method in Fetomaternal Hemorrhage. BIOMED RESEARCH INTERNATIONAL 2019; 2019:6481654. [PMID: 30931329 PMCID: PMC6413365 DOI: 10.1155/2019/6481654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/27/2018] [Revised: 12/05/2018] [Accepted: 01/31/2019] [Indexed: 12/03/2022]
Abstract
Screening of fetomaternal hemorrhage (FMH) is essential in management of fetomaternal antigen incompatibilities of blood. The objective in this study was to evaluate the ability of automatic blood analyzer (ABA) to screen FMH, also comparing this method with flow cytometry (FCM). The contents of fetal red blood cells and fetal hemoglobin were evaluated by FCM and ABA, respectively, using both blood samples of male adults laced with umbilical cord blood diluted at 1/10, 1/100, 1/1,000, and 1/10,000, or blood from puerperal women collected within 48 hours following delivery. FCM had better performance (area under curve, AUC = 0.8723) than ABA (AUC = 0.6569) in detecting fetal blood laced with blood from male adults. At a critical level of 0.5%, ABA indicated that 27.5% of puerperal women would have FMH while FCM did not detect FMH. Our results showed that ABA overestimates FMH and disagrees with FCM on indicating puerperal women with FMH. ABA is inadequate for being used to screen for or to measure FMH.
