目的:分析凶险型前置胎盘的临床特点,提高临床对凶险型前置胎盘的防治。方法:选取2012年1月~2014年6月在该院收治的凶险型前置胎盘孕妇22例为实验组,同时选取同期在该院收治的普通前置胎盘22例剖宫产的产妇为对照组,回顾性分析所有前置胎盘孕妇孕检次数、产前出血情况、产妇孕产情况及术中出血量、处理情况、输血量等资料进行统计分析。结果:实验组和对照组相比,孕妇发生凶险型前置胎盘胎盘植入的发生率为45.46%,产后平均出血量(2 653±360)ml和子宫切除率22.84%,两者明显高于对照组产后平均出血量(1 579±284)ml和子宫切除率4.83%。两者相比P<0.05,有统计学差异。结论:凶险型前置胎盘易发生胎盘植入,产后出血发生率高、出血量大、子宫切除率高,为孕产妇带来极大的威胁,采取有效的防治措施可减少不良反应的发生率,改善患者愈后恢复。 Objective: To analyze the clinical features of dangerous placenta previa and improve the prevention and treatment of dangerous placenta previa. Methods: Twenty-two pregnant women with precarious placenta previa admitted to our hospital from January 2012 to June 2014 were selected as the experimental group. At the same time, 22 pregnant women with cesarean section who were admitted to the hospital during the same period were selected as controls Group, retrospective analysis of all placenta previa pregnancy test frequency, prenatal bleeding, maternal and childbirth and intraoperative blood loss, handling, blood transfusion and other data for statistical analysis. Results: Compared with the control group, the incidence of placenta previa placenta accreta in pregnant women was 45.46%, the average amount of postpartum hemorrhage was (2 653 ± 360) ml and the hysterectomy rate was 22.84% The mean amount of postpartum bleeding in the control group (1,579 ± 284) ml and hysterectomy rate was 4.83%. P <0.05 compared with the two, there was a statistically significant difference. Conclusions: The placenta previa placenta accreta plagiocephalinis occurs easily, the incidence of postpartum hemorrhage is high, the amount of bleeding is large and the rate of hysterectomy is high, which poses a great threat to pregnant women. Effective prevention and treatment measures can reduce the incidence of adverse reactions , Improve the recovery of patients after healing.
