Continuation of enteral nutrition until extubation in critically ill patients

There is substantial variation in enteral nutrition practices for airway procedures in critically ill patients across individual specialists and intensive care units (ICUs). Fasting times can vary between 0 h and longer than 24 h before planned extubations. 1 Varghese JA Tatucu-Babet OA Miller E et al.

Continued enteral nutrition until extubation compared with fasting before extubation in patients in the intensive care unit: an open-label, cluster-randomised, parallel-group, non-inferiority trialContinued enteral nutrition until extubation in critically ill patients in the intensive care unit was non-inferior to a 6-h fasting maximum gastric vacuity strategy comprising continuous gastric tube suctioning, in terms of extubation failure within 7 days (a patient-centred outcome), and thus represents a potential alternative in this population.
