Objective: To study the clinical value of fetal monitoring in intrahepatic cholestasis of pregnancy (ICP).
Methods: Two hundred and six cases of ICP, delivering in our hospital from Dec. 1993 to Sept. 1998 were investigated. In these cases, 206 cases were examined by the fetal monitoring and vibratory acoustic stimulation test (VAS-T), 157 cases by ultrasonic umbilical artery flow analysis, and 127 cases by fetal electrocardiograph (FECG).
Results: There is a significant difference between normal and abnormal groups of the poor perinatal prognosis in contraction stress test (CST) and oxytocin challenge test (OCT) and ultrasonic umbilical artery flow analysis (P < 0.005, P < 0.05). There is no difference between normal and abnormal groups of the poor perinatal prognosis in NST, VAS-T and FECG.
Conclusion: CST, OCT and ultrasonic umbilical artery flow analysis have the higher clinical value to detect the poor placental function and to foretell the perinatal prognosis in ICP.
