Explain the Protein requirement in Postoperative Nutritional Care?

Increased catabolism leads to protein deficiency and hence negative nitrogen balance which amounts to loss of tissue proteins which call be as high as 1 lb per day. In addition, plasma proteins are lost through haemorrhage, wound bleeding and exudates. Metabolic losses also result from tissue inflammation, infection, trauma, immobilization and poor calorie intake. The protein deficit may cause serious complications, especially if the patient has some degree of previous malnutrition. Adequate intake of protein, is therefore, required to replace losses and meet the increased demand.
