Objectives: The present study compared respiratory parameters between the two methods of airwayestablishment, ETT and LMA, for patients scheduled for orthopedic surgery with general anesthesia.Methods: This randomized double-blinded clinical trial was conducted on patients scheduled for electiveorthopedic surgery under general anesthesia, in Bandar Abbas, Iran, from January 2021 to December 2021.Using a random allocation table, the study participants were randomly divided into two groups, to employeither ETT (n=48) or LMA insertion (n=48). The study’s ultimate goal was to assess the respiratory parametersin 1, 3, 5, 10, and 15 minutes following intubation.Results: At all-time points, the average of peak airway pressure (P peak) and P plateau parameters in theETT group was much higher than the EMA group (p<0.001 in all comparisons). The value of dynamic lungcompliance in the LMA group was significantly higher than the ETT group in all considered time periods(p<0.001 in all comparisons). The upward trend in the value of this index was significant only in the LMAgroup (p=0.030). There were no significant differences in arterial oxygen saturation and end-tidal carbondioxide levels between the two groups (p>0.05).Conclusion: In terms of arterial oxygen saturation stability and at the same time providing respiratory dynamiccompliance, the LMA device outperformed the ETT.
