Conservative Surgical Management of Early Postpartum Hemorrhage: A 12-Year Experience in a Tertiary Care Center in the South of Thailand.

Abstract

To evaluate the success rate and predictive factors of success in conservative surgical management of early postpartum hemorrhage (PPH). A retrospective study was conducted at a tertiary care hospital in the south of Thailand, from January 2006 to December 2017. PPH with conservative surgical management including Bakri balloon tamponade, B-Lynch uterine compression sutures, arterial embolization, vessel ligations, and combined surgical procedures was reviewed. The procedures were considered successful if bleeding could be controlled without subsequent hysterectomy. Multivariate logistic regression analysis was used to identify predictive factors for success of conservative surgical treatment. Among 39,327 deliveries, 1461 (3.7%) patients had early PPH, and 92 cases received conservative surgical management. Most patients (92.4%) underwent cesarean section. Median (IQR) blood loss before conservative surgery was 1800 (1100, 2575) mL, and median (IQR) time from early PPH to conservative surgical management was 41 (25.5, 60.0) minutes. The overall success rate of conservative surgical management was 80.4%, meanwhile the postoperative complication rate was 27.2%. The predictive factors significantly associated with success were maternal age < 35years (odds ratio [OR] 4.53, 95% confidence interval [CI] 1.27-16.23; p = 0.02), blood loss before conservative surgery < 1800mL (OR 5.82, 95% CI 1.45-23.33; p = 0.01), and time to start conservative surgery ≤ 40min (OR 4.76, 95% CI 1.13-20.12; p = 0.03). The overall success rate of conservative surgical procedures was high. Maternal age < 35years, blood loss before conservative management < 1800mL, and time to conservative surgery ≤ 40min were predictive factors of success.
