Continued Feeding Showed Similar Breathing-Tube Removal Failure Rates

Evidence

In a randomized trial involving more than 1,000 critically ill patients, failure after breathing-tube removal occurred within seven days in 17.2% with continued tube feeding versus 17.5% with fasting and feeding-tube suction. The observed difference was 0.3 percentage points. Pneumonia at 14 days was reported in 1.6% versus 2.5%, respectively.

These findings appear as cited evidence in the tube-feeding fasting consensus briefing, which covers American Society of Anesthesiologists guidance published October 28, 2026. Tube feeding, also called enteral nutrition, delivers nutrition through a tube into the digestive tract. Removing a breathing tube is called extubation. The randomized trial’s outcomes are distinct from the guidance study’s own measurements of expert agreement.

The guidance used a modified Delphi process: an international, multidisciplinary expert panel repeatedly reviewed and revised recommendations over four rounds. Initial recommendations drew on a systematic literature search, and a task force of practicing anesthesiologist intensivists assessed feasibility. By round four, all 20 recommendations had achieved stability.

For feeding delivered beyond the stomach until transport to the operating room, expert agreement was 100% in rounds one and two and 91% in round three. Those percentages measure agreement, not patient outcomes.

Analysis

Interpretation: The trial and the consensus recommendations address related decisions about interrupting tube feeding around procedures, but their evidentiary roles differ. The randomized comparison addresses outcomes around breathing-tube removal in critically ill patients. The consensus process organizes broader guidance where comparative evidence may be incomplete. Neither the trial’s numerical pattern nor high expert agreement establishes clinical effectiveness for all 20 recommendations.

Limitations

This is a single-briefing report about the guidance and the studies it cites, not independent corroboration from separately assessed trial reports. The briefing provides no confidence intervals—ranges expressing statistical uncertainty—statistical-test results, or margin defining how much additional risk would be acceptable. The close failure rates therefore cannot establish equivalent safety, and the lower observed pneumonia percentage is not enough to demonstrate a reduction.

The total expert-panel size is not reported. Only one task-force member had lived experience of critical illness, and the public was not included. Some recommendations reflect expert opinion where evidence is weak. For bolus feeding, meaning feeds delivered intermittently rather than continuously, the experts identified insufficient literature and endorsed case-by-case decisions rather than a uniform fasting approach.

What to watch

Direct comparative evidence for intermittent tube-feeding regimens would address an explicit gap. For the cited randomized trial, confidence would change with a confidence interval around the seven-day failure-rate difference and a prespecified acceptable-risk margin showing whether the results rule out a clinically important increase in failure with continued feeding.
