Hi there, Welcome to HCM, Obstetric cholestasis At term (40 weeks) with bile acids of 19 should be induced for delivery. There is no point waiting for labour to start, as every day more is a added risk for further rise in bile acid levels and may affect the baby. The problem of Obstetric cholestasis is it can cause sudden death in a full term baby as the bile salt can cause problem with the heart rhythm of the baby. And at 40 weeks the baby is fit to survive, so delivery should be induced immediately. The risk though less than 1 in 100 is still very important to make note as the baby is absolutely normal and has reached 40 weeks and to be affected by bile salts at this stage would be tragic. Also the risk of passing meconium during labour or in-utero is higher and also is the chance of operative delivery (caesarean or forceps) in women with Obstetric cholestasis. The risk of bleeding after birth in mother is also slightly higher and kept in mind. Vitamin K oral should be given to mother after 36 weeks. The liver function tests should be repeated 10 days after delivery as it takes that much time to get back to normal. Also the risk of repeat obstetric cholestasis in next pregnancy is very common up to 90% and should be informed to the doctor early in next pregnancy. Hope this helps. Regards.
