Background and Aims: Laryngeal Mask Airway has become a basic airway gadget needed for all age group patients. Search for the most successful laryngeal mask airway in terms of ease of insertion and oropharyngeal seal pressure continues. We evaluated the success rate of three types of LMA. Material and Methods: One hundred and twenty patients of either sex belonging to American Society of Anesthesiologists (ASA) physical status class I or II, between 1 to 6 years of age, scheduled to undergo elective surgery under general anaesthesia were included in the study. Patients were then randomly allocated to one of the three groups using coded envelopes as: group-I – (n=40), LMA Classic, group-II – (n=40), LMA Unique and group-III – (n=40), Ambu laryngeal mask. After induction with standard anaesthetic technique in group I and II, the LMA (Classic or Unique) was inserted using the standard method described by Brain with slight modification of partial inflation of cuff. In group III, the Ambu laryngeal mask was inserted using the pencil insertion technique as described in the instruction manual. Number of attempts for successful placement, ease of insertion, insertion time, fiber optic grade, oro-pharyngeal leak pressure and any evidence of post-op airway morbidity were noted. Results: The mean insertion time was 15.40±2.31 seconds for group I, 15.87±2.12 seconds for group II (LMA Unique) and 12.42±3.16 seconds in group III. There was no patient with oropharyngeal seal pressure (OSP) in the range of <15 cm H2O in group I (LMA Classic), while there were 2 (5%) in group II (LMA Unique) and 1 (2.56%) in group III (Ambu laryngeal mask). Maximum no. of patients in the three groups were in 15-20 cm H2O range of seal pressure. Fiber optic view Grade I was seen in 25 (62.5%) in group I & II and 24 (61.5%) patients in group III. The FOB grades were comparable in all the groups (p value=0.666). Overall all the groups had maximum number of grades I (62.18%) followed by grade II (26.05%). Conclusion: Ambu laryngeal mask and LMA Unique are comparable to LMA Classic in terms of the ease of insertion.
