Post-extubation Dysphagia: Does Timing of Evaluation Matter?

Area of Science:

• Clinical Medicine
• Otolaryngology
• Critical Care Medicine

Background:

• Swallowing evaluations post-extubation are often delayed, assuming functional improvement over time.
• Current guidelines lack evidence-based recommendations for the optimal timing of these evaluations.

Purpose of the Study:

• To determine if dysphagia, indicated by aspiration and diet modification needs, decreases within 24 hours post-extubation.
• To provide evidence-based guidelines for swallowing evaluation timing after extubation.

Main Methods:

• Prospective cohort study involving 49 patients undergoing FEES (Fiberoptic Endoscopic Evaluation of Swallowing) at 2-4 hours and 24-26 hours post-extubation.
• Comparison of Penetration-Aspiration Scale scores and diet recommendations between the two time points.
• Multivariable logistic regression analysis to identify factors associated with aspiration (e.g., age, admission reason, COPD history).

Main Results:

• 69% of patients could safely swallow at least one texture without aspiration within 2-4 hours post-extubation.
• A significant decrease in penetration/aspiration was observed at 24 hours post-extubation.
• 79% of participants demonstrated improved airway protection on at least one bolus type within 24 hours.

Conclusions:

• Swallow function generally improves within the first 24 hours following extubation.
• While patients may tolerate modified diets early, delaying evaluation until 24 hours could support less restrictive dietary recommendations.
• Findings support earlier swallowing evaluations to optimize diet modifications post-extubation.
