Background & aim: Severe obstetric hemorrhage remains a leading cause of maternal mortality globally, often resulting from complications such as uterine atony, placenta previa, and dystocia. This study aimed to investigate the risk factors associated with the need for blood transfusion in pregnant women undergoing vaginal or cesarean deliveries at Imam Sajjad Hospital in Yasuj during 2022–2023.
Methods: This descriptive-analytical study involved a complete census of pregnant women hospitalized for labor who were at least 24 weeks of gestation and required blood or blood product transfusion. Data were collected using a structured checklist covering demographic characteristics, obstetric history, underlying risk factors for bleeding, and details of transfusion. Quantitative variables were expressed as mean and standard deviation, while qualitative variables were described as frequencies and percentages. Group comparisons were performed using the Chi-square test via SPSS version 21.
Results: A total of 126 blood transfusions were recorded, with 47.6% occurring in vaginal deliveries and 52.4% in cesarean sections. The majority of recipients were aged 18–35 years (70%) and had a high body mass index (BMI ≥30 kg/m²) (90%). Comorbidities such as hypertension (21.2%) and diabetes (18.2%) were significantly more prevalent among women who underwent cesarean section and required transfusion. Most transfusions (84.1%) were administered to women with fewer than three prior deliveries. Uterine atony was the most common indication for transfusion in cesarean deliveries (65.6%), whereas placental abnormalities (e.g., retained placenta) and birth canal lacerations were the primary causes in vaginal deliveries (22.2%). Placental disorders (placenta previa, accreta, and abruption) were identified as critical predictors for transfusion need in cesarean sections.
Conclusion: The findings highlight that advanced maternal age, high BMI, and specific comorbidities are significant risk factors for blood transfusion needs. Identifying these local risk profiles is crucial for healthcare policymakers to enhance obstetric care quality and optimize blood bank management.
