Prophylactic B-Lynch suture: efficacy in preventing postpartum hemorrhage in high-risk patients

Abstract

Objective: To evaluate the effectiveness of prophylactic B-Lynch suture in the prevention of postpartum bleeding in patients at high risk for uterine atony, from the Concepción Palaces Maternity Delivery Room Service. Methods: Prospective, comparative and longitudinal study, which included 30 patients with risk factors for uterine atonia, randomly distributed in two groups: with and without B-Lynch compression suture. Echosonographic, clinical and paraclinical follow-up was performed at 12 and 24 hours after the postoperative period. A statistically significant contrast was considered if p < 0.05. Results: Haemoglobin reduction in patients with compressive suture was 0.5 ± 0.4 g/dl and hematocrit was 1.4 ± 1.1%; in the control group it was 1.6 ± 1.6 g/dl and 4 ± 4.7%, respectively (p-0.014/p-0.058). Bleeding at 12 and 24 hours was scarce in 73.3% and 93.3% of patients with compressive and moderate sutures or abundant in 100% and 93.4% of the control group (p-0.000). The reduction in the size of the uterus was greater in the experimental group than in the control group (p-0.000); 33.4% of patients with B-Lynch sutures and 93.4% without sutures had severe or unbearable pain at 12 hours (p-0.007) and at 24 hours there were no cases with severe or unbearable pain in the first group but in the second the frequency was 60%. Conclusions: Prophylactic B-Lynch suture is effective for preventing postpartum uterine atonia hemorrhage
