胎动NST和B超联合监测作为孕41周母婴高危程度的探讨

Monitoring The High Risk Factors of Mother and Infant by NST and B-ultrasound

目的观察胎儿宫内窘迫发病率和手术产率.方法对2006年6月至2007年7月在我院妇产科定期检查和分娩的孕妇共106例,对孕妇进行每周NST和B超检查等联合检测分三组观察比较.第Ⅰ组:孕41周组(孕周41～41周+6 d),第Ⅱ组:足月妊娠组(孕周37～40周+6 d),第Ⅲ组:过期妊娠组(孕周≥42周).结果孕41周组胎儿宫内窘迫及手术产的发生率高于足月妊娠组,与过期妊娠相似.结论妊娠41周后母婴存在一定程度的高危因素,应用多种监护手段进行检测,及时发现母儿异常给予相应处理,以降低围产儿病死率.

Objective To investigate the incidence of fetal distress in uterus and the rate of C-sect by NST and B-ultrasound every week.Method 106 cases of pregnant women who took examination and delivery in our hospital between Dec 2006 to Jul 2007 were divided into three groups： gestational age of 41weeks group（41 weeks～41 weeks ＋6 days）,term pregnancy group（37 weeks～ 40 weeks ＋6 days）,and prolonged pregnancy group（≥42 weeks）.Result The incidence of fetal distress in uterus and the rate of C-sect in gestational age 41weeks group,which were similar to prolonged pregnancy group,were higher than term pregnancy group.Conclusion There are some high risk factors in pregnant women whose gestational age was more than 41weeks,and multiple methods should be used to monitor the risk factors in order to reduce the perinatal mortality rate.
