Impacts of Related Risk Factors on the Efficacy of Interventional Treatment Towards Intractable Postpartum Hemorrhage

OBJECTIVE: To investigate the risk factors that impact the efficacy of interventional treatment of intractable postpartum hemorrhage (IPH). STUDY DESIGN: A total of 64 IPH patients were admitted and received interventional treatment at First Hospital of Shanxi Medical University from January 2012 to September 2014, among whom 57 cases were successfully treated (bleeding stopped), while 7 cases failed. The clinical data of the success group and the failure group were observed for the multivariate analysis of the possible reasons that might cause hemostatic failure. RESULTS: The univariate analysis of each suspected factor of hemostatic failure showed that history of uterine scar, combined use of uterotonics, uterine inertia, and placenta exhibited statistically significant differences between the 2 groups (p < 0.05); the multivariate logistic regression analysis showed that history of uterine scar and combined use of uterotonics were the risk factors for the interventional treatment failure of IPH, with OR values of 11.23 (95% CI 1.26 similar to 100.22) and 12.83 (95% CI 1.05-156.34), respectively. CONCLUSION: History of uterine scar and combined use of uterotonics were the risk factors for interventional treatment failure of IPH.
