Introduction: Nutritional support is an essential component in critical care. Malnutrition has been associated with poor outcomes among patients in intensive care units (ICUs), as indicated by increased morbidity, mortality, and length of stay.
Aim of the Work: The aim of this work is to discuss and review the effect of parenteral nutrition versus enteral nutrition on the outcome of patients requiring mechanical ventilation.
Methodology: Nutrition is an important aspect of patient care in acute or chronic critical illness. Appropriate nutritional support during the acute phase of critical illness has the potential to reserve or mitigate adverse consequences of poor nutritional status. An increasing nutritional deficit during a long ICU stay is associated with increased morbidity, infection rate, mechanical ventilation, length of stay, duration of recovery, and costs.
Conclusion: Recent studies mention that In mechanically ventilated patients in the ICU, ventilator-associated pneumonia rates, ICU and hospital lengths of stay, and ICU and hospital mortality rates of patients receiving PN are not significantly different than those in patients receiving EN, and feeding goals can more effectively be attained by PN. Yet, duration of mechanical ventilation is slightly longer in patients receiving PN, and Further studies to support this recommendation should be planned.
