Jaundice Flashcards
How can you tell whether a jaundice is prehepatic Vs Hepatic or post hepatic?
PREhepatic is: NORMAL urine NORMAL stools NO itching NORMAL liver tests
What’s gleeson’s 6 step approach to hepatic/post-hepatic jaundice Ix?
- imaging - rule out large duct obstruction
- Severely injury - high transaminases, ill pt, coagulopathy, encephalopathy - all need actioning ASAP
- ?Drug cause - stop drug
- Another “obvious” cause - Alochol, viral hep (contact Hx, prodrome), pregnancy, HF, Ca, Occupation
- FAST TRACK - non-invasive screen
- Liver biopsy - specialist decision
What drugs cause jaundice?
Possible drugs that will cause a biochemical profile similar to that seen in pre-hepatic jaundice, i.e. an unconjugated hyperbilirubinaemia include:
rifampicin
Possible drug-related causes of intra-hepatic jaundice include:
ethanol: cirrhosis
paracetamol, halothane, methyldopa, barbiturates
Possible drug-related causes of post-hepatic jaundice include:
isoniazid
chlorpromazine
What causes Ascities
Chronic Liver disease -Portal vein HTN Portal vein thrombosis Neoplasia Pnacreatitis Cardiac causes
What test do you do for ascities?
-Bloods: FBC, U&E, LFTs, Tumour markers
-Imaging: USS, CT
-Diagnostic Paracentesis:
Albumin levels (decreased = transudate, increased=exudate)
microscopy + cytology
How do you manage Ascittes?
- Fluid + salt restriction
- Dieretics - Spironolactone +/- Furosemide W/ Weight & U&E monitoring
- Large Volume paracenetsis
- TIPSS
What is a TIPSS?
- Transjugular intrahepatic portosystemic shunt
- Tx of ascities + bleeding varices
- Complication = encephalopathy due to blood bypassing the liver & not getting processed
