title: Effect of continuous cuff pressure regulator in general anaesthesia with laryngeal mask airway.
abstract: Postoperative pharyngolaryngeal complications (PPLC) occur during anaesthesia due to increased cuff pressure following the insertion of laryngeal mask airways. The use of a pressure regulator to prevent PPLC was evaluated in a prospective, randomized study. Sixty patients scheduled  to receive general anaesthesia were randomly assigned to two equal groups of 30, either with or without the regulator. The 'just seal' cuff pressure (JSCP), cuff pressure at 5-min intervals during anaesthesia, incidence of pharyngeal sore throat (PST), dysphagia, dysphonia and other complications  were evaluated at 1 and 24 h postoperatively. The combined mean ± SD JSCP of both groups was 20.3 ± 3.2 mmHg. In the group with the regulator, cuff pressure was maintained at a constant level during anaesthesia. This study demonstrated that the regulator is a simple, functional  device that can reduce the incidence of PST significantly at 1 h postoperatively, following general anaesthesia.
