Résumé
LMA In this single-center, prospective, observational study, we included 15 novice residents. Staff anesthesiologists recorded success or failure; insertion time; and incidences of bleeding or reflex including cough, hiccups, and limb movement. A successful pLMA insertion was defined as effective ventilation within two attempts with an insertion time of ≤ 120 s. Regarding CUSUM, we set acceptable and unacceptable failure rates as 20% and 40%, respectively. Further, α and β errors were designated as 0.1. We stratified the number of cases encountered by each resident into four groups of 10 cases each (1-10, 11-20, 21-30, and ≥ 31 cases) and evaluated the effects of learning. Each resident encountered 44 ± 5 (mean ± SD) cases of pLMA insertion, and 14/15 achieved proficiency in performing pLMA insertion after 20 ± 8 cases. Success rate (76%, 86%, 91%, and 93%; P < 0.001) and insertion time (45 s, 35 s, 31 s, and 26 s; P < 0.001) significantly improved with increased experience; however, incidences of bleeding (16%, 10%, 8%, and 10%; P = 0.124) and reflex (5%, 3%, 3%, and 3%; P = 0.54) remained unchanged. Experience with 20 ± 8 cases is needed to achieve proficiency in performing pLMA insertion for novice residents in a tertiary teaching hospital.
