Clinical value of fetal ECG in diagnosing intrauterine fetal distress
Zou Ping Obstetrical and Gynecologic Hospital Affiliated to Zhe jiang Medical University,Hangzhou 310006.
We have summed up 30 cases of fetal ECG of high risk pregnancies which were over 36 weeks of pregnancy and detected NST and B-Ultrasound respectively at the same time. The results have been compared and analysed. Our conclusion is that the fetal ECG is an objective index which can reflect whether the fetus in the uterus is normal or not. Abnormal fetal CG suggests that the fetus is hypoxic. If there is change of FST or FQRS is over 0.05 second, there may be cord around neck or oligoamnios; If the amplitude of FQRS is over 30uv, there may be oligoamnios or the fetus is 3500g or over. That the FQRS is 0.05 second or over, its amplitude is over 30uv and there is change of FST is an important index of abnormal FECG. The difference of sensitivities of detecting abnormal fetus rate among this method, NST and B-Ultrasound is obvious (P0.01)
