Measure
Fish Oil Emulsion Arm
In infants who meet the eligibility criteria for Fish Oil Emulsion arm received Fish Oil Emulsion (Omegaven) after enrollment under the study. Therapy with Fish Oil Emulsion (Omegaven) was provided at a dose of 1 gm/kg/day (by continuous infusion) and was infused intravenously through either a central or peripheral catheter in conjunction with parenteral nutrition. If previously on Intralipid, it was stopped prior to initiation of Fish Oil Emulsion.Fish oil emulsion. Treatment was given for as long as the child needed any TPN. If the infant no longer required any TPN, then the Omegaven was stopped. Omegaven was continued even after resolution of cholestasis, as long as the need for parenteral nutrition persisted.
