Abstract

Objective: Malnutrition is a common condition in critically ill patients requiring mechanical ventilation, negatively affecting treatment outcomes. This study aimed to evaluate the nutritional status and some associated factors in mechanically ventilated patients in the ICU. Subject and Method: A prospective descriptive study was conducted on 86 mechanically ventilated patients at the Department of Surgical Intensive Care and Organ Transplantation – 108 Military Central Hospital. Nutritional status was assessed using the Subjective Global Assessment (SGA), body mass index (BMI), and several biochemical markers at both admission and discharge. Clinical characteristics and treatment outcomes were also recorded. Result: The rate of malnutrition (SGA B and C) increased from 83.3% at admission to 95% at discharge (p = 0.003). Body weight and BMI decreased significantly (p < 0.001), while biochemical markers did not show significant changes. Poor nutritional status at admission was associated with older age, multidrug-resistant infections, and poor treatment outcomes (p < 0.05). Malnutrition at discharge was significantly associated with older age (p = 0.001), delayed initiation of enteral nutrition (p < 0.001), and renal dysfunction. Conclusion: Malnutrition is highly prevalent in mechanically ventilated patients and tends to worsen during hospitalization. Early nutritional assessment and intervention, especially via the enteral route, are essential to improve treatment outcomes.
