Randomized Controlled Trial
Tracheal intubation in patients with odentogenous abscesses and reduced mouth opening.
Odentogenous abscesses with involvement of the facial or cervical spaces can be life-threatening and often have to be drained under general anaesthesia. Trismus and swelling can make intubation with a Macintosh laryngoscope difficult or even impossible. However, indirect laryngoscopy has been successful when conventional direct laryngoscopy has failed. Therefore, we evaluated the efficacy of the Glidescope laryngoscope in patients with odentogenous abscesses and the improvement in mouth opening after neuromuscular block. ⋯ In patients with odentogenous abscesses, the use of a Glidescope laryngoscope was associated with significantly faster tracheal intubation, with a better view, fewer supporting manoeuvres, and a higher success rate than with a conventional laryngoscope. Improvement of the inter-incisor distance after induction of anaesthesia correlated with the duration of symptoms.
