Description of Parenteral Nutrition Infusion

Groups	Caloric Delivery (kcal/kg/day)*	Protein Delivery (g/kg/d)	Fat Delivery (g/kg/d)	% of normal enteral caloric intake	PN Infused Rate (ml/hr)
Full PN, n=5	471	19.2	7.7	100%	0.4
Reduced PN, n=6	353	14.4	5.8	75%	0.3
Very Low PN, n=7	236	9.6	3.9	50%	0.2
Control ^ (enteral), n=6**	486	30	6.6	100%	0.2 (saline)

Mean caloric delivery was based on the initial average body weight (22 grams). There was no difference between groups in initial body weight. PN groups did not receive any enteral intake. Abbreviation: PN, parenteral nutrition.
