Comparative Evaluation of Macintosh, MacCoy and Airtraq Laryngoscope in Simulated Difficult Laryngoscopy Using Rigid Neck Collar

Government Medical College, Haldwani·interventional·Posted Mar 13, 2015·Updated May 4, 2015

In Brief

A clinical study evaluating Intubation- Macintosh laryngoscope, Intubation- MacCoy laryngoscope, and 1 other intervention for Intubation; Difficult. Completed, enrolled 120 participants.

Detailed Summary

Tracheal intubation requires alignment of oro-pharyngeal-laryngeal axes. When these three axes are not aligned, intubation becomes difficult. In the researchers' study, the investigators simulated difficult laryngoscopy situation by using a rigid neck collar. This neck collar renders intubation difficult not only by restricting neck movement, but also reducing mouth opening. The investigators compared the performance of Macintosh, MacCoy and Airtraq laryngoscope in simulated difficult laryngoscopy using a rigid neck collar.

Interventions

Intubation- Macintosh laryngoscopedevice

Difficult intubation was simulated by using rigid neck collar. Then patients were intubated according to the assigned laryngoscopes. In Macintosh group, tip of the laryngoscope blade was placed in the vallecula and epiglottis was lifted. After visualization of the vocal cord, patients were intubated.

Intubation- MacCoy laryngoscopedevice

In MacCoy group, tip of the laryngoscope blade was placed in the vallecula and lever was pressed to flex the tip. After visualization of the vocal cord, patients were intubated.

Intubation- Airtraq laryngoscopedevice

In Airtraq group, the laryngoscope was loaded with endotracheal tube. Airtraq laryngoscope was inserted through midline and after visualization of image of vocal cord through its eyepiece, endotracheal tube was passed.
