Factors determining successful liver preservation for transplantation.

Auxiliary liver allotransplants will survive for relatively long periods of time after 24 hour hypothermic (10-12C), pulsatile perfusion. The best perfusate was a silica gel fraction of dog plasma with added potassium chloride gel made hyperosmolar with glucose. Further improvement could be achieved with added allopurinol and methylprednisolone. Nonpulsatile flow or lower temperatures were less effective preservation techniques.
