Background: Postpartum hemorrhage (PPH) remains one of the most critical causes of maternal morbidity and mortality worldwide, with uterine atony being its most common underlying cause. Prompt and effective management is crucial to reduce complications and preserve reproductive potential. The B-Lynch suture, a uterus-sparing surgical technique, offers a mechanical approach to control bleeding when medical interventions fail, especially in low-resource settings where hysterectomy may not be feasible or desirable.
Objective: To determine the effectiveness of the B-Lynch suture technique in controlling primary postpartum hemorrhage due to uterine atony.
Methods: This quasi-experimental study was conducted in the Department of Obstetrics and Gynecology at Khyber Teaching Hospital, Peshawar, from May 16 to November 16, 2024. A total of 151 postpartum women aged 18 to 40 years were enrolled using consecutive non-probability sampling. All participants were diagnosed with uterine atony-induced PPH, defined as blood loss exceeding 500 mL within the first 24 hours of delivery. The B-Lynch suture was applied using chromic catgut No. 2 under supervision of a consultant obstetrician. Hemostasis was assessed 12 hours post-procedure. SPSS version 25 was used for data analysis, and chi-square testing assessed associations at a significance level of p<0.05.
Results: The mean age of participants was 27.28 ± 5.85 years, mean BMI was 25.18 ± 1.45 kg/m², and mean gestational age was 38.11 ± 2.05 weeks. Hemostasis was successfully achieved in 120 out of 151 patients, yielding an overall effectiveness rate of 79.5%. No major complications were reported, and all women retained uterine integrity.
Conclusion: The B-Lynch suture is a highly effective, fertility-preserving intervention for managing primary PPH due to uterine atony and should be incorporated into routine obstetric practice, particularly in resource-constrained environments.
