Abstract
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.

Prediction of extubation outcome in critically ill patients: a systematic review and meta-analysis. Crit Care. 2021; 25: 391 Crossref PubMed Scopus (11) Google Scholar A question that remained unanswered was whether it is really safe to continue enteral nutrition until attempting to extubate. 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.
