Effect of Enteral Versus Parenteral Nutrition on Outcome of Medical Patients Requiring Mechanical Ventilation

Abstract

In mechanically ventilated patients in the medical 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.
