Laryngeal tube S II, ProSeal laryngeal mask, and EasyTube during elective surgery: a randomized controlled comparison with the endotracheal tube in nontrained professionals.

Background And Objective: EasyTube (EZT), ProSeal laryngeal mask airway (PLMA), and Laryngeal tube S II (LTS II) have recently been introduced as supraglottic airway devices and have been proposed as emergency airway alternatives. The purpose of this study was to compare the performance of the three devices, if used by anaesthesiologists without extensive hands-on training, with the endotracheal tube during routine surgical procedures.

Methods: After informed consent, 88 ASA I-II patients scheduled for routine minor surgery were randomly allocated to EZT (n=22), PLMA (n=22), and LTS II (n=22) groups and the endotracheal tube (n=22) group, respectively.
