150 adult patients undergoing general anaesthesia were randomly assigned to 3 groups for ventilation via one of the SADs. Speed and ease of insertion, ease of gastric tube insertion, amount of gastric contents drained, leak pressure, and complications were all recorded. Patients were interviewed 1 and 24h after surgery to determine the incidence and severity of sore throat, hoarseness and dysphagia.
