Abstract
Introduction: The present study compared video laryngoscope with Macintosh laryngoscope in terms of laryngoscopic time, total intubation time, Cormack and lehane scale and stress response while intubating. Materials and methods: After a standardized technique of induction of anesthesia, Group MCL (53 cases) intubated with Macintosh laryngoscope and Group VVL (53cases) intubated with Vividtrac Video laryngoscope. We compared laryngoscopic time, total intubation time, Cormack and lehane scale and stress response while intubating in these two groups. Results: The heart rate and blood pressure was above immediately after post intubation and started declining to reach post induction value at about three to five minutes in both groups (p values > 0.05).The mean tracheal intubation time was 11.05 seconds in MCL group and 18.05 seconds in VVL group (p-0.001). All cases in VVL group were intubated in first attempt, but one patient in MCL group required two attempts for success (p->0.05). Visualisation of glottis and non-alignment of the airway axis was better with VVL (p-0.001). There is no desaturation noted in all of the 106 cases. Conclusion: Vivid trac Laryngoscope has a comparable similar safety profile with Macintosh laryngoscope with respect to deleterious haemodynamic response produced by rigid manipulation of airway. Vivid trac Video Laryngoscope, a rigid channeled indirect laryngoscope provides always the better view of the laryngeal inlet than the Macintosh direct laryngoscope. Intubation time in Vividtrac video laryngoscopy was more than conventional laryngoscopy.
