This prospective, randomized controlled study will be conducted after approval by the institute ethics committee. A written, informed consent would be obtained from the child’s relative. The selected patients will undergo routine pre anaesthesia checkup.                                                                                                 

After shifting the child to operating room, standard ASA monitors will be connected  like ECG, pulse oximeter and non-invasive BP monitoring and baseline vitals will be checked.Then child will be randomized to be included in any of the two groups (group A or group B). If patient will have intravenous cannula in situ then induction of anaesthesia will be done will propofol 2mg/kg. If patient will be not having IV cannula in situ then induction of anaesthesia will be done with 8% Sevoflurane in 100% O2, after induction of anaesthesia, IV cannula will be inserted. Then IV Fentanyl 1-2 mcg/kg and muscle relaxant Atracurium 0.5 mg/kg will be administered and lung will be ventilated for 3minutes. Laryngoscopy will be done with either CMAC Miller size1 blade [GROUP-A] or CMAC Macintosh size 2 blade[GROUP-B]. Both the blades will be inserted along the right angle of the mouth and pushing the tongue towards left side keeping the blade in the midline. Tip of the blades will be placed in vallecula  with upwards force to lift the epiglottis to achieve the best glottis view. After achieving best glotticview,appropriate sized styletted endotracheal tube (ETT) will inserted through the glottis and blade will be removed. Airway maneuvers like external laryngeal manipulation or neck flexion or extension will be allowed incase of difficulty in glottis view and/or intubation.                                                                                                                                                     

During this procedure the time variables like time for obtaining best glottic view,time for intubation and time for the procedure are measured by another individual.  Appropriate position of ETT will be confirmed by checking bilateral equal air entry on auscultation. After successful intubation, close circuit will be connected and controlled ventilation will be initiated. Rest of the anaesthesia maintenance will be done according to anaesthetist’s choice.                                                                                                                   

Reversal will be done by Neostigmine(50mcg/kg) and Glycopyrrolate(10mcg/kg).
