Registration Number: CTRI/2020/10/028667

Lead Sponsor: Department of Anaesthesiology

Brief Summary: Tracheal intubation should be done with utmost precaution in cervical spine injury patients as it possess great challenge to anaesthesiologist for securing airway. Neck restriction is highly essential to prevent neurological damage, failing can lead to morbidity and mortality. Studies have been done using various airway gadgets in simulated restricted neck for tracheal intubation.

There is lack in literature review on Adult Miller laryngoscope for intubation in such patients.

Hence we would like to compare the performance of Miller with McCoy and Macintosh adult laryngoscoes for Oro tracheal intubation using soft cervical collar, creating a simulated restricted neckmobility.

Patients randomly assigned to three groups with 30 patients in each based on the device used for laryngoscopy. In Group 1 - Miller laryngoscope blade, Group 2 - McCoy laryngoscope blade and Group 3 - Macintosh laryngoscope blade. The endotracheal cuffed tube of established appropriate size will be advanced into the trachea under direct vision with or without bougie. Finally, the scope will be removed and circuit will be connected. The adequacy of ventilation will be confirmed by Capnography and Chest auscultation.

If first attempts fail second operator will intervene. If second attempt fails, it will be considered as failure and the cervical collar will be removed and intubation will be done with conventional laryngoscope.

First attempt success rate is defined as single passage of endotracheal tube with or without bougie.

All intubations will be performed and risk management will be taken care by 5 year experienced anesthesiologist .

All parameters will be recorded as per the protocol.
