AimsThe study is aimed to compare the efficacy of I-gel and ProSeal laryngeal mask airway (PLMA) in nonparalysed anesthetized individuals following manufacturer-recommended digital insertion.Materials And MethodsIn this prospective randomized observational study, 40 American Society of Anesthesiologists I and II patients, aged 18-65 years scheduled for elective surgical procedures were allocated either to PLMA group (Group P, n = 20) or the I-gel group (Group I, n = 20). Following digital insertion of PLMA or I-gel, the following parameters were compared: insertion time, ease of insertion, number of attempts, failed insertion, airway reaction during insertion, oropharyngeal leak (OPL) pressure, and gastric insufflation on auscultation. Fiberoptic view of both the channels of the airway devices and ease of insertion of 12 F Ryle's tube through gastric drain channel were graded. Postoperative complications were also noted.ResultsFirst attempt and overall insertion success were similar (PLMA, 85% and 100%; I-gel 80% and 100%, respectively). Mean (standard deviation) insertion times were similar (PLMA, 27.40 [11.51] s; I-gel 25.45 [9.03] s). Mean OPL pressure was 3.5 cm H2O higher with PLMA (P < 0.012). The passage of Ryle's tube was easier through I-gel than PLMA. Grade I glottic view (full view of the vocal cords) was visible in 17 (85%) patients who were managed with I-gel whereas only 9 (45%) patients had Grade I view in the PLMA group.ConclusionThe time required for digital insertion of PLMA and I-gel in nonparalyzed anesthetized patients is similar but PLMA forms a better oropharyngeal seal. I-gel is better positioned over the laryngeal framework and esophagus. I-gel allows easier passage of Ryle's tube through its drain channel than PLMA. The incidence and severity of postoperative sore throat and hoarseness was higher with PLMA.Copyright: © 2019 Anesthesia: Essays and Researches.
