Why is it important?
Introduction: LMAs is a valuable rescue device in both elective and emergency situations for both anticipated and unanticipated difficult airways. Many studies have shown that rotational technique has been proven to be much more effective in pediatric age group avoiding injury to pharynx without buckling the tip of LMA. This prompted us to study this rotational technique in adult population and compare it with the standard one. Aims and Objectives: To study the classic laryngeal mask airway insertion comparing standard and partial cuff inflated rotational technique with respect to ease of insertion and occurrence of complications. Materials and Methods: Ethical committee approval and informed consent obtained, 140 patients of age 18 to 70 years, ASA I and II posted for short surgical procedures under general anesthesia were randomized into Group S (Brain’s Standard insertion Technique) and Group R (Partially inflated Rotational Technique). Appropriate sized LMA was inserted was hemodynamics monitored. Data Analysis: Continuous variables were analyzed with the unpaired t-test. Categorical variables were analyzed with the Chi-square Test and Fisher Exact Test. Statistical significance was taken as p < 0.05. Results: Both groups were comparable with respect to demography. Statistically significant difference among the group with respect to first attempt success and LMA insertion time. Hemodynamically both groups were comparable. There were no statistically significant difference in complications. Conclusion: We conclude that the Standard technique of LMA insertion is a better technique when compared to Rotational technique with respect to ease of insertion and lesser number of complications.
