| Abstract
Objectives: Considering uncertainty about the effect of age on the success rate of laryngeal mask airway (LMA) insertion, the
present study aimed to evaluate the success rate of LMA in airway management in different age groups.
Materials and Methods: A total of 183 patients, admitted to the 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 the number of LMA insertion attempts
and LMA insertion complications. The data were analyzed in SPSS20 through ANOVA and the chi-square test at P<0.05).
Results: There were statistically significant differences between different age groups regarding resistance against LMA insertion
(P=0.008) so that insertion was mostly comfortable and easy in the first attempt in the adult group compared to other groups.
However, no statistically significant difference was observed between different groups in terms of the rate of air leakage (P=0.129),
the duration of successful LMA insertion (P=0.119), and the number of LMA insertion attempts (P=0.091). Regarding the LMA
insertion complications, laryngospasm was significantly higher in the middle-aged and aged group (P=0.009), and blood
observation on LMA was significantly higher in the pre-school and child group (P=0.005).
Conclusions: According to the results of this study, there was no difference between different groups in terms of successful LMA
insertion and post-LMA insertion complications. |
