Randomized Controlled Trial Multicenter Study Clinical Trial
Randomized crossover comparison of the proseal with the classic laryngeal mask airway in unparalysed anaesthetized patients.
The ProSeal is a wire-reinforced laryngeal mask airway with an additional drain tube that leads to the distal tip of the laryngeal cuff. The design should improve the seal with the larynx. ⋯ The ProSeal is more difficult to insert than the classic laryngeal mask airway but allows positive pressure ventilation more reliably than the classic laryngeal mask airway.
