Abstract: Objective：To investigate the clinical value of peg-suture to postpartum hemorrhage caused by uterine inertia. Methods：There are 218 cases of postpartum hemorrhage during Jan. 2007 to May. 2014, 82 cases of them received conservative treatment (uterine massotherapy, oxytocin, hemabate and so on), there is no effect. Observing group include 40 cases received peg-suture, control group 1 include 20 cases received B-Lynch suture, control group 2 include 22 cases received gauze pocking of uterine. The patients with complete uterine inertia were performed ovarian artery ligation and uterine artery ligation. To compare the effect of hemostasis, healing of uterine incision, blood flow of uterine, complication, uterine involution, ejection of lochia and reappearance of menstruation. Results：The hemostasis rate in each of the 3 groups are 100%, 85.00% and 81.8%, the differences are significant (P＜0.05). In the three groups, healing of uterine incision, blood flow of uterine and ovary are well. In the observing group, 6 cases run fever, in control group 1, 3 cases run fever, 1 case get intestinal obstruction, in control group 2, 6 cases run fever, 2 cases the gauze are sutured with incision of uterine, the differences are not significant (P＞0.05). In the three groups, the difference of uterine involution, ejection of lochin and reappearance of menstruation are not significant (P＞0.05). Conclusions：To postpartum hemorrhage caused by uterine inertia, peg-suture has high rate of success, good hemostasis effect and low complication, operation time is short, manipulation is simple, so is worth spreading.
