Poster Session II
Post- partum hemorrhage (PPH) is an obstetrical emergency with rising incidence, and a major cause of maternal morbidity. We sought to find prominent risk factors for early PPH in patients with vaginal vs. cesarean deliveries (CD).
Study Design:
A population-based retrospective cohort study was conducted in which all singleton deliveries occurring between 1991 and 2016 at a tertiary medical center were included. Risk factors for early PPH (occurring within 24 hours post-partum) were examined in the general population, and specifically in women following vaginal and CD. Generalized estimating equation (GEE) models were to control for confounders.
Results:
During the study period, 322,497 deliveries were included in the analysis, of which 279,435 (87%) were vaginal deliveries and 43,062 (13%) were CD. A total of 1811 (0.6%) deliveries were complicated with early PPH; of which 0.5% were vaginal (n=1657) and 0.05% (n=154) were CD. Uterine ruptures, placenta previa, prolong 2nd stage of labor, placental abruption and large for gestational age were the strongest risk factors for early PPH (Table 1). Most risk factors were similar in women with vaginal and CD, as seen in the logistic regression models adjusting for confounders (Table 2).
Conclusion: Risk factors for early PPH do not differ significantly between vaginal or cesarean deliveries.
