ENDOTRACHEAL TUBE SIZE AND POST OPERATIVE SORE THROAT IN WOMEN: RCT

Postoperative sore throat and hoarseness are common and disturbing complications following endotracheal intubation, and women are more frequently affected by these symptoms. The purpose of an endotracheal intubation is to ensure a secure airway and provide an opportunity for positive pressure ventilation and minimal risk of aspiration.The cause of POST could be mucosal injury in the trachea or vocal cord injury,and there are several contributing factors for these injuries. Previously recognized risk factors for POST include female gender, size of the ETT, grade of difficulty in intubation, and duration of surgery. If the ETT cuff is overinflated, it might damage the mucosa and cause POST.
