Fetal outcome in obstetric cholestasis.

Area of Science:

• Obstetrics and Gynecology
• Perinatology
• Maternal-Fetal Medicine

Background:

• Obstetric cholestasis is linked to increased stillbirth and perinatal complications.
• Previous studies highlight significant risks associated with this condition.

Purpose of the Study:

• To evaluate the effectiveness of intensive fetal surveillance and early intervention in reducing perinatal mortality in pregnancies complicated by obstetric cholestasis.
• To identify reliable methods for predicting fetal compromise in these high-risk pregnancies.

Main Methods:

• Retrospective analysis of 83 pregnancies complicated by cholestasis (1975-1984).
• Monitoring for meconium staining, preterm labor, and intrapartum fetal distress.
• Evaluation of cardiotocography, estriol levels, liver function tests, ultrasound, and amniocentesis for predicting fetal compromise.
• Assessment of perinatal mortality rates compared to a previous series.

Main Results:

• High incidence of meconium staining (45%), preterm labor (44%), and fetal distress (22%).
• Perinatal mortality decreased from 107 to 35/1000 births in the study period.
• Amniocentesis identified meconium in 8 of 26 pregnancies; other methods failed to predict fetal compromise.
• Early intervention was indicated in 49 pregnancies, with 12 due to fetal compromise.

Conclusions:

• Intensive fetal surveillance, including amniocentesis for meconium detection, is crucial.
• Induction of labor at term or with a mature lecithin/sphingomyelin ratio may reduce stillbirth rates.
• This approach offers a strategy to improve outcomes in high-risk obstetric cholestasis pregnancies.
