摘要
本文观察了孕37～42周单胎头位的孕妇164例临床检查可疑有脐带异常者进行联合监测,监测指标:1.临床检查;2.B 超检查;3.胎心监护,有异常者。产时详细记载脐带与新生儿的关系,证实急性胎儿窘迫的原因,将以上检查结果与产前联合监测核实,计算出假阳性和假阴性率、阳性和阴性预测率。结果:164例可疑有脐带异常产时已被证实者149例,阳性符合率为90.85%,无围产儿死亡。149例脐带异常中以脐带缠绕为多数,占91.95%,且脐带缠绕周数与其长度呈正相关。单项监护符合率以 B 超较高为75%,临床检查与胎心监护的符合率相近,分别为59.8%、57.9%。若联合监护出现异常项目越多,脐带异常发生率越高,剖宫产的机率也越高,并对联合监护诊断脐带异常的价值及处理进行了讨论。
Combined monitorings were done in 164 cases suspicious of abnormal position ofthe umbilical cord in clinical examination,The monitoring methods were as follows:a,Clinical examination;b.B-Scanning;c,Fetal heart rate monitoring,The relation-ship between the umbilical cord position and the neonate was recorded in detailduring delivery to find and prove the exact cause of acute fetal distress in order tocheck the result,False positive and false negative rates and also the positive andnegative predictive rates were then calculated,It was proved that 149 of the 164cases were in abnormal position of umbilical cord,The positive predictive rate was90.85% with no perinatal fetal death.The B-scan coincidence was 75%,Thecoincidence rates for clinical examination and fetal heart monitoring were 50.8% and57.9% respectively,The B-scan coincidence rate was the highest,The more the mori-toring abnormalities were found the higher the morbidity of abnormal umbilicalcord position was and also the higher cesarean section rate presented,Evaluationof combination of monitoring in the diagnosis and treatment of abnormal umbilicalcord position was discussed.
