SUCCESS RATE OF B-LYNCH SUTURE IN MANAGING PRIMARY POSTPARTUM HEMORRHAGE (PPH) SECONDARY TO UTERINE ATONY

Abstract

Objective: To determine   success rate of   B-Lynch suture in managing primary postpartum hemorrhage (PPH) secondary to uterine atony and to identify clinical factors associated with its outcome.

Materials and Methods: This descriptive cross-sectional study was conducted on 97 patients presenting with primary PPH due to uterine atony. Data were collected over six months using consecutive sampling from Aug 24 to Jan 25. Patients aged 16–38 years who failed to respond to medical uterotonics underwent B-Lynch compression suture procedure. Success was defined as   effective control of hemorrhage without requiring radical surgical interventions like hysterectomy. Data were analyzed using descriptive statistics and   Chi-square test to evaluate associations.

Results:   Mean age of   participants was  28.46 SD 4.66  years.   majority were multigravida (49.5%) and booked cases (66%).   overall success rate of   B-Lynch suture was 70.1% (n=68). A statistically significant association was found between Pregnancy Induced Hypertension (PIH) and procedural outcome ( p=0.029 ), with lower success rates observed in patients with PIH (53.3%). Parity showed a trend toward significance ( p=0.083 ), with higher success in grand multi-parous women. No significant associations were found with booking status, mode of delivery, or volume of blood loss ( p>0.05 ).

Conclusion:   B-Lynch suture is an effective uterine-sparing intervention for refractory PPH caused by uterine atony, achieving success in over two-thirds of cases. While highly effective across various clinical profiles, its success may be influenced by   presence of maternal comorbidities like PIH.
