Explain obstertic cholestatsis and it’s management
Increase in bile salts
- leads to itching in mothers
- can in extreme cases lead to death and apoxia (severe hypoxia) in babies due to immature liver being unable to break down increase in bile salts and bile salts causing placental vasoconstriction
Presents
- Itching
- ~Jaundice
- Increase in bilirubin
Management
- Induction of labour at 37-38wks
- Ursodeoxycholic acid
- Vit K supplements

CT scan - rule out stroke if presenting in that way
- LWMH
- Warfarin (3-6mnth = provoked, 6-12mnth = unprovoked, lifelong = 2+ episodes)
Empty delta sign = CT w/ contrast reveals empty delta sign at posterior of skull - normally contrast would run through the sagittal sinus but clot means no contrast getting through hence “empty”
