A comparative study of tracheal intubation using i-gel and air-Q intubating LMA.
Anesth Pain Intens Care Jan ;18(4):367-70.

Objective: Various supraglottic devices (SGD’s) have been used as a conduit for tracheal intubation particularly in difficult airway situations when an endotracheal tube is a must. Various SGD’s tried for this purpose include Intubating Laryngeal Mask Airway also called the C-Trach™ laryngeal mask, LMA Fastrach™, air-Q™ intubating LMA and the i-gel™ supraglottic airway. In this study we used air-Q™ LMA and i-gel™ for blind tracheal intubation in patients with normal airways and compared the rates of successful intubation. Methodology: 100 patients were randomly divided into two groups. For Group A, air-Q™ was used for blind tracheal intubation while for Group B i-gel™ LMA was used. Correct placement of ETT was confirmed by capnography. Results: Success rate for blind tracheal intubation through air-Q™ was 82% while that for i-gel it was 54% (p-value 0.003). Conclusion: The success rate for blind tracheal intubation through air-Q™ intubating laryngeal mask airway is higher as compared to that for blind tracheal intubation through i-gel™.
