Postoperative sore throat related to the use of a Guedel airway
Abstract:
Eighty-eight patients in ASA classes 1 or 2 and aged between 18-65 years, who were to undergo anaesthesia, were allocated randomly to a group with or without an airway. Methohexitone, nitrous oxide, alfentanil and enflurane were used, with the patients breathing spontaneously. This study showed that there was no significant difference between the two groups in the incidence of sore throat, or any other related symptom, and concludes that the use of an oropharyngeal airway does not increase morbidity among nonintubated patients.

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
