Randomized Controlled Trial Comparative Study
Controlled comparison between betamethasone gel and lidocaine jelly applied over tracheal tube to reduce postoperative sore throat, cough, and hoarseness of voice.
Postoperative sore throat, cough, and hoarseness of voice though minor sequelae after general tracheal anaesthesia can be distressing to the patient. ⋯ A wide spread application of betamethasone gel on the tracheal tube decreases the incidence and severity of postoperative sore throat, cough, and hoarseness of voice.

Randomized Controlled Trial
Tracheal intubation of morbidly obese patients: a randomized trial comparing performance of Macintosh and Airtraq laryngoscopes.
The Airtraq laryngoscope is designed to allow visualization of the glottis without alignment of the oral, pharyngeal, and laryngeal axes. We hypothesized that this new airway device would facilitate tracheal intubation of morbidly obese patients. We compared tracheal intubation performance of standard Macintosh laryngoscope with the Airtraq laryngoscope in morbidly obese patients. ⋯ In this study, the Airtraq laryngoscope shortened the duration of tracheal intubation and prevented reductions in arterial oxygen saturation in morbidly obese patients.

Randomized Controlled Trial Comparative Study
Pathways through the nose for nasal intubation: a comparison of three endotracheal tubes.
In nasotracheal intubation, there are two main pathways in the nostril through which the endotracheal tube may pass. The lower pathway lies along the floor of the nose underneath the inferior turbinate. The upper pathway lies above the inferior turbinate, just below the middle turbinate. The lower pathway may be considered to be the safer route as it is located away from the middle turbinate and cribiform plate. ⋯ Endotracheal tubes, particularly preformed tubes, frequently take the less favourable pathway during nasotracheal intubation, in spite of specific attempts to avoid this.
