Nutritional support of critically ill patients is often suboptimal, due to problems with both nutrient prescription and delivery. The objective of the study is to assess the adequacy of nutritional support in terms of nutrient intake, nutritional status, severity of illness, change in biochemical parameters, and length of hospitalization, ventilation support days and mortality. 35 patients admitted in the ICU were selected and followed till discharge. Majority (71%) were males. Majority (15%) diagnosed with pulmonary disease. Initial SGA assessment showed 54% of the subjects in mild-moderately undernourished category and 46% in well nourished category. The mean requirements were 1715±220.04kcals of energy, 63.97±9.8gm of protein and 235.81±30.25gm of carbohydrate. The mean ventilation support days were 7.43. There was a significant (p<0.01) improvement in MAC and MAMC values of male and TLC in both gender. Finally 60% of the subjects were found to be well nourished. There was a significant (p<0.01) difference between initial and final values of APACHE score in all subjects which shows a reduction in the risk of mortality. The current study reinforces the importance of calorie and protein delivery to critically ill patients who are on ventilator support. Inadequate calorie and protein delivery is associated with higher odds of mortality.
