- Primary Outcome Measures
Name Time Method Primary Objective: To prove that the â??Time To Intubate (TTI)â?? the trachea with DLT using McGrath videoscope is similar to that with MacIntosh laryngoscope, with an accepted difference of 20 sec (non inferiority study design) <br/ ><br> <br/ ><br>Timepoint: After induction of anesthesia, the muscle relaxant will be adminstered . After 4 minutes intubation will be attempted. Time from passage of scope to first capnograph deflection is the Time to intubate (TTI) comparision between the TTI of two scopes is the primary endpoint.
- Secondary Outcome Measures
Name Time Method Is there any difference in the numbers of failures between the scopes? <br/ ><br>2.What are the complications that are encountered with either scope? <br/ ><br>3.How easy is it to intubate using the two scopes on the basis of NRS Score- 1(extremely easy)- 10 (extremely difficult ).? <br/ ><br>Timepoint: Sore throat and hoarseness will be evaluated 12-24 hours after surgery.
