Intervention	The treatment group will receive glutamine-supplemented parenteral nutrition. The control group will receive isonitrogenous parenteral nutrition. All patients will have data collected once a week on clinical state, feeding, liver and renal function tests, ammonia, septic episodes and parenteral nutrition lines
