The value of routine hemoglobin level evaluation following elective cesarean section: Is it worthwhile?

Abstract

AbstractObjectiveThe aim of this study was to assess the usefulness of routine hemoglobin testing following elective and urgent cesarean section (CS) in patients without primary postpartum hemorrhage (PPH).MethodsThis retrospective cohort study included women who underwent vaginal delivery (VD), elective CS, and urgent CS at Carmel Medical Center from 2015 to 2020. Data were extracted from the obstetric database, excluding deliveries with PPH. Demographic and obstetric variables were recorded. Primary outcomes were the need for packed red blood cell transfusion.ResultsA total of 19 446 women were included, with five (0.3%) requiring a blood transfusion in the elective CS group, 27 (0.17%) in the VD group, and eight (0.4%) in the urgent CS group. Urgent CS was associated with a higher risk of blood transfusion, but there was no significant difference between elective CS and VD. Elective CS showed the lowest rates of post‐delivery hemoglobin below 7 g/dL 1 (0.1%) compared to VD 16 (0.6%) and urgent CS 13 (0.7%).ConclusionRoutine postoperative hemoglobin testing following elective CS in asymptomatic patients without PPH appears unnecessary. This study supports reconsidering routine hemoglobin testing following elective CS, aligning with the goal of optimizing resource utilization while maintaining patient quality.
