目的研究分析导致晚期产后出血的原因,为进一步治疗和预防提供方案。方法选取45例晚期产后出血患者,对其临床资料进行研究探讨。结果胎盘胎膜残留21例(占46.67%),子宫胎盘附着面复旧不良12例(占26.67%),软产道裂伤9例(占20.00%),子宫切口愈合不良3例(占6.67%)。晚期产后出血主要原因是胎盘胎膜残留、子宫胎盘附着面复旧不良、软产道裂伤、子宫切口愈合不良。结论在自然分娩的患者中,胎盘胎膜残留是导致晚期出血的主要因素;对于剖宫产患者,子宫切口愈合不良是导致晚期产后出血的重要因素。临床处理包括抗感染、促进子宫收缩以及手术治疗。
Objective To study and analyze the causes of postpartum hemorrhage in late stage and to provide a plan for further treatment and prevention. Methods 45 cases of postpartum hemorrhage were selected and their clinical data were studied. Results There were 21 cases (46.67%) of placenta residual membrane residual defects, 12 cases of uterine placenta adhesion defects (26.67%), 9 cases of soft birth canal laceration (20.00%) and 3 cases of poor uterine incision healing (6.67% . Late postpartum hemorrhage is mainly due to residual fetal placenta, uterine placenta attached to the surface of poor old, soft birth canal laceration, uterine incision healing. Conclusion In patients with spontaneous labor, placental residual membrane is the main factor leading to late bleeding. In patients with cesarean section, poor healing of uterine incision is an important factor leading to postpartum hemorrhage. Clinical management includes anti-infective, uterine contractions and surgical treatment.
