- Brief Summary
Patient undergoing elective surgery under general anesthesia (except obstrectic surgery) will be recruited in this study. Participants (novice residents) will be allotted in two groups , by asking them to pick a chit randomly from a box containing 15 chits . Some chits will be (group C)Mc-coy blade and other(group M) Macintosh blade for intubation. Once the residents are allotted in a particular group, he/she will continue to use the blade allotted to that group for laryngoscopy and intubation .Each resident will do about 8-9 intubations . -Pre anesthetic check up will be carried out in all the patients. -On arrival to operation theatre, standard intra-operative monitoring with electrocardiogram, pulse oximetry and non invasive and manual blood pressure will be attached and baseline vitals will be noted. -The laryngoscopy blade will be given according to allotted category. -In pre medication inj Glycopyrolate 0.005-0.01mg/kg, Inj Midazolam (0.1-.0.2mg/kg) iv, Inj fentanyl (1-2mcg/kg) , inj Lignocaine(2% preservative free )3 cc iv given Patient pre-oxygenated with 100 % O2 through closed circuit delivered via spontaneous ventilation for 3 minutes. The induction of anesthesia will be done with inj propofol according to weight (2-2.5mg/kg) muscle relaxation achieved with inj Succinyl-Choline (1.5-2mg/kg) . After achieving adequate muscle relaxation, in sniffing position laryngoscopy will be performed with laryngoscope blade 3 for female and blade 4 for male. The novice resident will be asked about glottic view that will be achieved by his/her at first attempt by showing them by Cormack Lehane classification chart .They will be asked to indicate the Cormack Lehane , grade 1/2 will be achieved by external laryngeal maneuvers after which intubation will be done by Portex endo-tracheal tube , if novice is not able to achieve grade 1 or 2 then adjustment of the blade or external laryngeal manipulations will be done . Total time of 30 seconds will be given to the novice resident for placement of the endotracheal tube , after that the senior resident will take over the procedure. The time duration will be noted from insertion of laryngoscope into oral cavity till attainment of 5-7 successive square waveforms in capnograpghy. In group M patient intubated with Mackintosh blade and In group -C patient will be intubated with Mc-coy blade .

- Not specified
- Primary Outcome Measures
Name Time Method laryngeal exposure –Achievement of Cormack Lehane Grade I / II Grade 1: Most of glottis is visible Grade 2: The posterior aspect of glottis is visible Grade 3: Only epiglottis is seen, no part of laryngeal inlet is visible Grade 4: The epiglottis is not visible 6months
- Secondary Outcome Measures
Name Time Method Secondary objective: A).Success at first attempt intubation. B).To look for any complications: 1) Trauma to teeth & oral mucosa 2) Esophageal intubation 3) Desaturation due to inability to intubate in 1st attempt (spo292%) 4) Pressure response to intubation (alteration in BP 20% and HR 20% from baseline)in terms of additional amount of inj propofol required to maintain hemodynamics. 30 Seconds
