Clinical analysis of 46 cases on emergency hysterectomy for postpartum hemorrhage.

Objective To explore the risk factors and the time of hysterectomy for intractable postpartum hemorrhage. Methods A retrospective analysis was performed on 46 cases of emergency hysterectomy for postpartum hemorrhage, who were admitted to our hospital between January 2010 and December 2014. Results During five years, there were total 56436 delivery cases and 582 cases of postpartum hemorrhage in our hospital. The incidence rate of postpartum hemorrhage was 1.03%. 46 cases were processed emergency hysterectomy due to inefficient conservative theatments. The causes of postpartum hemorrhage incuded placenta factors (43.48%, 20/46), uterme atony(36.96%, 17/47), uterme atony with placenta factors (10.87%, 5/46), amnionic fluid embolism(4.35%, 2/46), and late postpartum hemorrhage(4.35%, 2/46). Range of blood loss was 1 500~4 000 ml. The average of blood loss was 2855±500 ml. All of 46 patients were recovered. Conclusions Emergency hysterectomy is effective treatment for severe postpartum hemorrhage with inefficient conservative theatments. Placenta factors is the main cause of emergency hysterectomy. We should take effective measures in prevention and treatment of postpartum hemorrhage in order to reduce the occurrence rate of hysterectomy.
