Brief Summary

A PROSPECTIVE RANDOMIZED STUDY TO COMPARE THE EFFICACY OF C-MAC VIDEO LARYNGOSCOPE, VL3R VIDEO LARYNGOSCOPE AND MACINTOSH LARYNGOSCOPE AS INTUBATING AIDS IN ADULT PATIENTS

Airway management is quite essential in cardiopulmonary resuscitation, anaesthesia, emergency medicine, intensive care and first aid, as it saves lives. Laryngoscopy may be performed to facilitate tracheal intubation during general anaesthesia or [cardiopulmonary resuscitation](https://en.wikipedia.org/wiki/Cardiopulmonary_resuscitation) or for [surgical](https://en.wikipedia.org/wiki/Surgery) procedures on the larynx or other parts of the upper [tracheobronchial tree](https://en.wikipedia.org/wiki/Respiratory_tract#Respiratory_tree). Direct laryngoscopy (DL) does not always allow optimal viewing of the glottis, especially in those patients with anatomical characteristics which can make tracheal intubation difficult1. The American Society of Anesthesiologists’ closed claim study showed that difficult intubation or esophageal intubation is the cause of the approximately 35% of life-threatening respiratory events, including death and permanent brain damage2. Thus managing a difficult airway is one of the major problems that an anaesthesiologist can encounter in clinical practice.

These issues have stimulated the development of multiple novel laryngoscopes, each of which aims to improve the laryngeal view, especially in cases of anticipated/unanticipated difficult airway3. The greater effectiveness of video-laryngoscopes associated with multi-person visualization could enhance overall patient safety during airway management4. Although they offer several advantages, including better view of glottis entrance and intubation conditions, a good laryngeal view does not guarantee easy or successful tracheal tube insertion5.

We therefore aim to compare the number of attempts required for successful intubation using C – MAC video laryngoscope, VL3R video laryngoscope and Macintosh laryngoscopes and to arrive at a conclusion and to grade them based on the various characteristics.
