Conditions

Health Condition 1: null- ASA grade I-II Patients planned for surgery needing lung isolation technique with predicted normal airways

Interventions

Intervention1: Videolaryngoscope- Mc Grath blade: 2 scopes are being compared for ease of intubation of double lumen tube Intervention2: No new inteervention planned in the study. Intubation is the on

Design outcomes

Primary

Measure	Time frame
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) 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

Measure	Time frame
Is there any difference in the numbers of failures between the scopes? 2. What are the complications that are encountered with either scope? 3. How easy is it to intubate using the two scopes on the basis of NRS Score- 1(extremely easy)- 10 (extremely difficult ).? Timepoint: Sore throat and hoarseness will be evaluated 12-24 hours after surgery.	—
