Comparison of C-MAC and Mc-GRATH laryngoscopes for intubation in COVID scenario

INTERVENTION: Intervention1: Intubation with video‐laryngoscope: Intubation on a manikin with CMAC or McGrath MAC videolaryngoscope, with the intubating person wearing face protective PPE. Time to intubation defined as the time from passing the blade of largoscope between teeth of manikin to the visualization of first chest expansion. Time to intubation noted by an independent observer. intubating person to be randomly allotted one of the two laryngoscope to be used first and then use the second laryngoscope. time to intubation with both to be noted and compared. Control Intervention1: Comparison between C‐MAC and McGrath MAC laryngoscope, on a manikin with the intubating person wearing face protective PPE.: Time to intubation to be noted. Defined as the time starting from passing the tip of the laryngoscope blade into the mouth of the manikin till observation of first chest expansion with the resuscitation bag) Control Intervention2: Not applicable: Not applicable CONDITION: PRIMARY OUTCOME: Time to intubation with each device. (Defined as the time starting from passing the tip of the laryngoscope blade into the mouth of the manikin till observation of first chest expansion with the resuscitation bag)Timepoint: Outcome noted at ‐ Baseline.(i.e. at the time of intubation). SECONDARY OUTCOME: 1) Number of attempts taken for successful intubation. ; 2) Cormack‐Lehane (CL) grade. ; 3) POGO (Percentage of glottic opening) score. ; 4) Optimization manoeuvres ; 5) Dental trauma ; 7) Userâ??s preference between the two laryngoscopes â?? based on the following parameters a) ease of insertion of laryngoscope blade b) ease of visualization of vocal cords c) ease of passing the endotracheal tube d) overall preference.Timepoint: Immediately after intubation. INCLUSION CRITERIA: medical professionals (non anaesthetists) with no previous experience of intubation with video laryngoscopes.
