Explain the Energy requirement in Postoperative Nutritional Care?

Adequate calorie intake is critical for successful outcome of surgery and should be provided in the form of carbohydrates and fal. Energy requirements are generally high post operatively due to hyper-metabolism. The energy requirement of the patient should be such as to be able to maintain a energy equilibrium or in other words stabilization of body weight at the pre-operative level. The energy requirement may be as high as 4000 to 6000 Kcal a day although such a high intake is usually not practically feasible.
