Prehospital tracheal intubation in trauma patients frequently contaminates vocal cords with blood or gastric contents. This finding impacts airway management strategies, especially the use of the laryngeal mask airway.

Area of Science:

  • Emergency Medicine
  • Anesthesiology
  • Trauma Care

Background:

  • Prehospital tracheal intubation is a critical intervention for trauma patients.
  • The risk of vocal cord contamination during emergency airway procedures is a significant concern.
  • Understanding contamination sources is vital for preventing complications.

Purpose of the Study:

  • To determine the incidence and origin of vocal cord contamination in trauma patients undergoing prehospital tracheal intubation.
  • To assess the implications of contamination on airway management choices.

Main Methods:

  • Prospective study of 53 trauma patients requiring prehospital tracheal intubation.
  • Visual inspection of vocal cords for gross contamination (blood, gastric contents) post-intubation.

Main Results:

  • 34% of patients (18/53) exhibited gross vocal cord contamination.
  • Blood was the most common contaminant (15 patients), followed by gastric contents (3 patients).

Conclusions:

  • Vocal cord contamination is common following prehospital tracheal intubation in trauma.
  • Findings necessitate careful consideration of airway management techniques, including the laryngeal mask airway, in prehospital settings.
