A prospective, randomized comparison of the LMA-protector™ and i-gel™ in paralyzed, anesthetized patients.

ABSTRACT: BACKGROUND:In the present study, we compare the LMA-Protector™ and the i-gel™ in terms of adequacy of the airway seal, insertion time, ease and accuracy of insertion, and the incidence of postoperative sore throat. METHODS:In 110 anesthetized and paralyzed adult patients, the i-gel™ (n?=?55) or the LMA-Protector™ (n?=?55) was inserted. The primary outcome was airway leak pressure. The secondary outcomes included the first-attempt success rate, insertion time, ease and accuracy of the device insertion, ease of gastric tube placement, blood staining on the device after removal, and incidence and severity of postoperative sore throat. RESULTS:The airway leak pressure was higher with the LMA-Protector™ than with the i-gel™ (31 [7] cmH2O vs. 27 [6] cmH2O, respectively; P?=?0.016). Insertion time was longer with the LMA-Protector™ than with the i-gel™ (27 [16] sec vs. 19 [16] sec, respectively, P?
