Abstract

Background: Postpartum hemorrhage (PPH) remains a leading cause of maternal morbidity and mortality globally, with uterine atony accounting for the majority of cases. In severe instances, unresponsive bleeding may require emergency surgical intervention, which poses a risk to maternal health and fertility. Uterine compression sutures, particularly the B-Lynch technique, have emerged as an effective method for hemorrhage control and uterine preservation. However, local data supporting its efficacy remain limited.
Objective: To assess the outcome of B-Lynch suture in patients with postpartum hemorrhage.
Methods: This descriptive case series was conducted at the Department of Obstetrics & Gynecology, Lady Willingdon Hospital, Lahore, over six months from December 2024 to May 2025. A total of 90 patients, aged 18–40 years and presenting with atonic PPH unresponsive to medical therapy, were enrolled through non-probability consecutive sampling. B-Lynch sutures were applied under spinal anesthesia by a single surgical team. Patients were monitored postoperatively for 24 hours. Outcome variables included operative time, estimated blood loss, fall in hemoglobin, and need for blood transfusion. Data were recorded on a structured proforma and analyzed using SPSS version 25.
Results: The mean age of the patients was 29.43 ± 6.77 years, with a mean BMI of 25.86 ± 4.30 kg/m² and gestational age of 38.73 ± 1.13 weeks. The mean operative time was 53.03 ± 4.58 minutes, mean blood loss was 748.34 ± 89.97 mL, and mean fall in hemoglobin was 0.99 ± 0.61 g/dL. Blood transfusion was required in 6 (6.67%) patients.
Conclusion: The B-Lynch suture technique proved to be a safe and effective surgical intervention for controlling postpartum hemorrhage, with favorable outcomes in operative time, blood loss, hemoglobin reduction, and transfusion need.
