Soft Palate Perforation with Endotracheal Tube During Video Laryngoscopy

Vollständiger Abstract

Worum geht es in dieser Arbeit?

Case presentation: A 57-year-old man with a history of obesity-hypoventilation syndrome, diabetes mellitus, and chronic renal insufficiency was intubated with an 8.0-mm endotracheal tube under video laryngoscopy in the emergency department due to respiratory failure. After successful intubation, bloody secretions were noted in the patient’s mouth. Subsequent examination revealed that the endotracheal tube had caused a through-and-through perforation at the junction of the soft palate and the anterior tonsillar pillar. Because the intubation had been successful, the endotracheal tube was not removed, and the soft palate was transected to free the tube. The patient made an uneventful recovery. Discussion: Soft palate perforation is an uncommon injury that has been reported more frequently with video laryngoscopy than direct laryngoscopy. To prevent this injury and ensure its rapid recognition, it is recommended that the clinician sequentially look at the “5 M’s” during intubation: Mouth–Monitor–Mouth–Monitor–Mouth.
