Methods The delivery modes in gynecological patients in our hospital were input to statistical analysis,the postpartum hemorrhage in cesare-an section and vaginal delivery were comparative study, the difference in bleeding frequency, hemorrhage cause,blood loss of two groups were compared. Results The blood loss of caesarean section was significantly higher than that of vaginal delivery (P<0.05). The difference of bleeding time in two delivery modes was not significant (P>0.05).The main reason for vaginal delivery of postpartum hemorrhage was uterine inertia,while the main reason for hemorrhage of cesarean section was operation factors or position. Conclusion Clinical analysis of postpartum hemorrhage in cesarean section and vaginal delivery situation and the reason of difference is helpful to the prevention and the control of mater-nal postpartum hemorrhage.
