Feeding Study - Effects Post-cardiac Surgery

Feeding is initiated on first postoperative day. Bolus feeds are started at 1 mL/kg every three hours and up-titrated by 1 mL/kg every feed (Q 3 hours) to a goal of 10 mL/kg/feed (equivalent to approximately 50 kcal/kg/day). Feeding volume will exceed 20 mL/kg/day by 6 hours following protocol initiation and reach target feeds by 27 hours of protocol initiation.

Feeding is initiated on first postoperative day. Bolus feeds are started at 3 mL every three hours for 24 hours. Bolus feeds then up-titrated by 1 mL/kg every-other feed (Q 6 hours) for 24 hours. Bolus feeds then up-titrated by 1mL/kg every feed for to a goal of 10 mL/kg/feed (equivalent to approximately 50 kcal/kg/day). Feeding volume will reach target feeds by 60-63 hours after protocol initiation.
