The Success Rate of Classic Laryngeal Mask Airway Insertion During General Anesthesia in Different Age Groups

Objectives: Uncertainty about the effect of age on the success rate of laryngeal mask airway (LMA) insertion led us to conduct the present study to evaluate the success rate of LMA in airway management in different age groups. Materials and Methods: A total of 183 patients, who were admitted to Shohada hospital (Tabriz, Iran) during 2018-2019, were enrolled in this descriptive, cross-sectional, prospective study. The patients were selected through the convenience sampling method and divided into 4 age groups. After anesthesia, patients were compared in terms of duration and number of LMA insertion attempts and LMA insertion complications. The data were analyzed using SPSS20 through one-way ANOVA and the Chi-square test at P
