凶险性前置胎盘33例临床分析

Clinical Analysis of 33 Dangerous Placenta Previa Cases

目的:探讨凶险性前置胎盘的治疗与术中出血量关系。方法:对33例凶险性前置胎盘患者(观察组)和36例非凶险性前置胎盘患者(对照组)均采用手术治疗。观察两组术中出血量、产后输血量及胎盘植入发生率、子宫切除率。结果:观察组术中出血量、产后输血量及胎盘植入发生率、子宫切除率均明显高于对照组(P<0.05或P<0.01)。结论:凶险性前置胎盘胎盘植入发生率高,产后易大出血,围产期子宫切除率高,降低剖宫产率,加强围产期管理,适时、适术终止妊娠,及做好充分术前准备是诊治成功关键。

Objective： To explore the relationship between the treatment of severe placenta previa and intraoperative blood loss. Methods： Thirty - three patients with severe placenta previa （ observation group） and 36 patients with non - dangerous placenta previa（ control group）were treated with surgery. The blood loss, postpartum blood transfusion, the incidence of placenta accreta and hysterectomy were observed. Results： The blood loss, postpartum blood transfusion, placenta accretion rate and hysterectomy rate in the observation group were much higher than those in the control group（P 〈0. 05 or P 〈0. 01 ）. Conclusions： The incidence of placenta accreta and postpartum hemorrhage are high, and the perinatal hysterectomy rate is high, meanwhile, the rate of cesarean section is reduced, the management of perinatal period is strengthened, and the pregnancy is terminated timely. Preparation is the key for successful treatment.
