Impact of early nutrition and feeding route on outcomes of mechanically ventilated patients with shock: a post hoc marginal structural model study

摘要

Few data are available about optimal nutrition modalities in mechanically ventilated patients with shock. Our objective was to assess associations linking early nutrition (< 48 h after intubation), feeding route and calorie intake to mortality and risk of ventilator-associated pneumonia (VAP) in patients with invasive mechanical ventilation (IMV) and shock.
