Evaluation of Swallow Function Post-Extubation: Is It Necessary to Wait 24 Hours?

Area of Science:

• Critical Care Medicine
• Otolaryngology
• Gastroenterology

Background:

• Post-extubation dysphagia increases risks of pneumonia, longer hospital stays, and re-intubation.
• Current practice often delays swallow evaluations for 24 hours post-extubation.

Purpose of the Study:

• To determine if delaying swallow evaluation for 24 hours post-extubation is necessary.
• To assess the safety and efficacy of early post-extubation swallow assessments.

Main Methods:

• Prospective study involving 202 adult patients across 5 ICUs.
• Swallowing was evaluated at 1, 4, and 24 hours post-extubation using the Yale Swallow Protocol.
• Investigated factors associated with nonfunctional swallowing post-extubation.

Main Results:

• 82.2% of patients passed the swallow screening at 1 hour post-extubation.
• 87.6% passed by 4 hours, and 91.6% by 24 hours.
• Intubation duration of 4 days or longer was significantly linked to impaired swallowing.

Conclusions:

• Early swallow assessment (within 1 hour) post-extubation is not necessary to delay.
• The majority of patients can safely undergo swallowing evaluation shortly after extubation.
• This approach may help mitigate complications associated with post-extubation dysphagia.
