[Perinatal monitoring in intrahepatic cholestasis of pregnancy].
The sensitivity of meconium stain in amniotic fluid for prediction of fetal well-being in intrahepatic cholestasis of pregnancy(ICP) was evaluated. The study consisted of an ICP group(n = 30), and a control group (n = 30) and the umbilical arterial pH value(< 7.2) was used as a standard. The positive and negative predicttive valus of meconium-stained amniotic fluid in ICP group were 80.0%; the positive and negative predictive values in control group were 60.0% and 92.0% respectively. There was no significant difference (P > 0.05) between the two groups in positive and negative predictive values. However, the positive and negative predictive values of the two groups were high, which indicated that meconium-stained amniotic fluid related to fetal hypoxia. Moreover, the incidence of meconium-stained amniotic fluid in ICP was higher than that in control (40.0%: 16.70%, P < 0.05). Therefore, we suggest that the amniotic fluid of patients with ICP should be observed very closely. When meconium-stained amniotic fluid is discovered, delivery by cesarean section is imminent.
