Abstract

Introduction: Postpartum hemorrhage (PPH) is one of the five most dangerous obstetric complications and remains a leading cause of maternal mortality worldwide, particularly in low- and middle-income countries. Despite considerable advances in obstetric care, the incidence of postpartum bleeding remains substantial and continues to cause severe complications within the first 24 hours after delivery. Objective: To investigate the characteristics of blood loss and associated factors among women undergoing normal vaginal delivery at Thanh Phu Regional Medical Center in 2025. Subjects and Methods: A cross-sectional descriptive study was conducted on 80 women who delivered vaginally and were monitored during the first 24 hours postpartum at Thanh Phu Regional Medical Center from March to October 2025. Data were collected through interviews and medical records, and analyzed using statistical software. Results: Most participants were younger than 35 years, worked in agriculture, and delivered at term; overweight status accounted for 26.3%. The primary causes of postpartum bleeding were physiological bleeding after placental expulsion (81.3%), followed by uterine atony (16.3%). The mean blood loss was relatively low. Risk factors for increased blood loss included multiparity, macrosomia, antenatal anemia, and hypertensive disorders of pregnancy. Conclusion: This study provides practical evidence on the extent of blood loss and associated risk factors for PPH at the primary healthcare level. The findings support improved early recognition, prevention, and timely management to reduce maternal complications and mortality.
