Background and Aims: Since introduction of classic LMA by Archie Brain, the newer second generation extraglottic airway devices are easily available in the market; the current study was designed to assess and compare the relative success rate of blind endotracheal intubation in first attempt through LMA-Fastrach, Air-Q ILA, and Ambu Aura-i as a primary endpoint. Methods: One hundred and fifty patients aged between 18 and 60 years with ASA physical status I-II, MP Grade 1-II, undergoing elective surgery under general anaesthesia, were enrolled into this prospective, randomised, case-control study to compare the relative success rate of tracheal intubation through LMA- FastrachTM(Group F=50 patients) Air-QTM ILA (Group Q = 50 patients) and AMBU-Aura i (Group A=50 patients) in first attempt via standard PVC tube. Results: First attempt successful intubation through SAD was 92% in group F, 88% in group Q and 84% in Ambu aura i group but no significant difference was seen among the groups. However, tracheal intubation was performed successfully in shorter time with Air Q-ILA (34.91±11.61 sec) as compared to AMBU-Aura and ILMA (36.59±13.92 and 37.66±12.66 sec) which was statistically insignificant (p= 0.599). Conclusion: All the three second generation extraglottic airway devices are reliable and effective can be used as conduit for tracheal intubation safely without any major complication with high success rate.
