47例不典型胎盘早剥的产前漏诊原因分析

Clinical analysis of prenatal misdiagnosis causes of 47 cases of atypical abruptio placentae

目的探讨不典型胎盘早剥的产前漏诊的原因。方法以我院2011年1月至2013年1月收治的120例胎盘早剥患者为研究对象，根据产前是否确诊，将研究对象分为观察组（产前漏诊，47例）与对照组（产前确诊，73例），采用回顾性研究的方法，对两组患者的人口学资料、胎盘早剥诱因、临床指标及胎盘早剥的面积等四项进行比较。探讨产前漏诊胎盘早剥患者的特点及漏诊原因。结果观察组患者胎盘早剥的诱因主要集中在应用催产素（40．43％）和胎膜早破（44．68％）上，早产的发生率高于对照组（53．19％vs．9．59％），胎盘早剥面积比例小于对照组，其差异有统计学意义（P〈0．05）。结论不典型胎盘早剥诱因和临床表现不明显，应采用多种诊断方法，并结合病史，对孕妇进行鉴别诊断。

Objective To analyze causes of prenatal misdiagnosis of abruptio placentae. Methods 120 cases of abruptio placentae in our hospital from January 2011 to January 2013 were divided into observation group （prenatal misdiagnosis, 47 cases） and control group （prenatal diagnosis, 73 cases）. Retrospectively studied demographic data, causes of placental abruption, clinical indexes and the area of placental abruption of two groups. Results The major causes of placental abruption in observation group were the application of oxytocin （40.43%） and premature rupture of membranes （44.68%）. The rate of premature delivery in observation group was higher than that in control group （53.19% vs. 9.59%）. The area proportion of placental abruption in observation group was less than that in control group （P 〈 0.05）. Conclusion Causes and clinical manifestation of atypical abruptio placentae were not obvious. Multiple diagnosis methods are helpful to get satisfactory diagnosis effect.
