Pray, pray, pray that there is an active hepatology service where you are going. That will significantly reduce your pain on transplant. If not, you become the hepatology service and will have to manage all the super sick pts with liver disease awaiting transplant. Review all the liver diseases.
Also review tylenol OD. Frequently these pts are sent from Podunk Hosiptal when they present at the ED with transaminases > 3000. The doc panics and sends the pt to transplant center. Most will get better without transplant. Take a look at King's critera. Follow trends in transaminases, INR and T bili. And make sure to get your poison control folks involved for mucomyst (N-acetycystine) dosing.
Your call duties will include preping pts for transplant when a liver becomes available. The coordinator (usually a nurse) calls you to tell you they are bringing in Mr X for a liver. If you are ata program that uses "extended criteria" livers, be sure to ask if it is and if so, why (you'll have to include that information in the consent...there will likely be a special consent). There should be a packet with a standard order set for what to order for these pts.
While the service can be painfully busy, try to get to the OR and see a transplant...it's very cool surgery. Also try to get to a harvest.
And remember that while it's overwhelming to start on transplant, you'll get a painful service out of the way early.
Good luck
