Design outcomes

Primary

Measure	Time frame
Evaluation of first attempt success rate of blind intubation through LMA Blockbuster and LMA ProtectorTimepoint: It will be considered only when the endotracheal tube will be inserted into green channel of LMA until the confirmation through capnographic waveform in first attempt	—

Secondary

Measure	Time frame
Comparison of time for successful tracheal intubationTimepoint: The time for successful tracheal intubation will be started when the endotracheal tube will be inserted into the green channel of LMA until the confirmation through capnographic waveform.Time for first intubation attempt will be measured only;ComplicationsTimepoint: Number of patients complaining of immediate sore throat. blood staining on the device – yes/no. Number of patients complaining of vomiting will be noted. ;Hemodynamic changesTimepoint: pulse rate, SBP, DBP, MAP, SpO2 will be noted before and after (immediately, 1min & 5min) device insertion;Number of attempts taken for intubationTimepoint: More than 2 attempts will be considered as failure of blind intubation and ventilation was continued through LMA.;Number of Manouvers required to intubate through Supraglottic device Timepoint: Chandy manouvre Jaw thrust manouver	—
