246例完全性胎盘前置出血的临床观察及对妊娠结局的影响

目的:为预防及降低孕产妇及胎儿死亡率提供理论依据,对近3年来确诊的246例完全性胎盘前置出血患者的临床资料分析研究。方法:采用回顾性分析对246例诊断为完全性胎盘前置的危险因素、妊娠结局进行统计分析。随机选择过去2年妇产科收住的246例非病理性妊娠妇女的临床资料进行对比。结果:反复妊娠、既往宫腔内操作史是发生前置胎盘的主要危险因素;完全性前置胎盘出血患者妊娠结局与非病理性妊娠孕产妇比较有显著差异;出血量的多少对妊娠结局有一定影响。结论:提高对危险因素的认识、适时剖宫产终止妊娠可有效改善妊娠结局。

Clinical observation on hemorrhage of 246 cases with complete placenta praevia and the effect on pregnancy outcome

Objective:To provide theoretical basis for preventing and reducing maternal mortality and fetal mortality,analyze and research the clinical data of 246 patients with hemorrhage of complete placenta praevia in recent three years.Methods:The risk factors and pregnancy outcomes of 246 cases diagnosed as complete placenta praevia were analyzed retrospectively,the clinical data of 246 hospitalized women without pathological pregnancy in recent two years were selected randomly as control group.Results:Repeated pregnancy and intrauterine operation history were the main risk factors of placenta praevia;there was significant difference in the pregnancy outcome between the cases with complete placenta praevia and the women without pathological pregnancy;the amount of blood loss had a certain impact on pregnancy outcome.Conclusion:Improving the cognition about risk factors and terminating pregnancy timely by cesarean section can improve the pregnancy outcome effectively.
