Resolution of laryngeal injury following translaryngeal intubation.
Translaryngeal intubation (TLI) causes mucosal ulcerations of the vocal cords and posterior laryngeal commissure. Usually these ulcers heal by primary reepithelialization, but occasionally laryngeal granulomas or strictures develop at these ulcer sites. The incidence of granuloma and stricture formation and the variables influencing abnormal laryngeal healing following TLI are not well understood. ⋯ Laryngeal symptoms, particularly hoarseness, resolved as the larynx healed. Performance of tracheostomy, age, TLI for more than 10 days, and severe laryngeal injury at extubation did not influence the median time to resolution of laryngeal abnormalities. Abnormal laryngeal healing following TLI is uncommon but is not exacerbated by prolonged TLI (more than 10 days), severe laryngeal injury at extubation, or performance of a tracheostomy.

Oxygen saturation and cardiovascular changes during fibreoptic intubation under general anaesthesia.
Sixty patients who required fibreoptic nasotracheal intubation were studied. Arterial oxygen saturation, arterial blood pressure and heart rate were monitored continuously during fibreoptic intubation under deep halothane anaesthesia. ⋯ Almost one third of the patients (18 out of 60) suffered a decrease in arterial oxygen saturation below 90% during the intubation sequence and in five patients the saturation fell below 80%. The episodes of desaturation were not related to the induction-intubation time or to the grade of laryngeal visibility at direct laryngoscopy.

The Bullard laryngoscope is an anatomically shaped rigid fiber optic instrument designed for indirect laryngoscopy and intubation. It requires no neck extension nor flexion to perform laryngeal intubation. This characteristic is especially useful in the case of difficult airway. ⋯ The Endotrol tube itself has such a suitable shape for nasal intubation that it can be introduced to the larynx with little directional change. Therefore, our method is mastered with a shorter training period than the intubation method with fiber-optic laryngoscopes. In conclusion, our intubation method with the Bullard laryngoscopes using the directional tip tubes (Endotrol) is useful for patients with difficult airways, and is also nontraumatic and easy to perform.
