Exclusion criteria

Exclusion criteria: 1. Patients with BMI >30 2. Anticipated difficult airway (neck pathologies, restriction of mouth opening 3.Hemodynamic instability (ASA III and IV) 4.Patients having contraindication to Supraglottic airways device use (Emergency Surgeries, Full stomach, Aspiration risk, CKD patients, Pregnancy) 5.serology positive patients(HIV,HBsAg,HCV)

Design outcomes

Primary

Measure	Time frame
To compare the Fibreoptic glottic visualization score (BRIMACOMBE BERRY SCORE) and the first pass success rate of fIbreoptic guided intubation through Blockbuster LMA and Ambu Auragain LMA in patients with simulated restriction of neck movements. Timepoint: Outcome (brimacombe berry score ) will be assessed right after LMA is placed and fibreoptic scope is introduced through LMA. FIBREOPTIC GLOTTIC VISUALISATION SCORE (BRIMACOMBE BERRY SCORE ) 1 No cords seen but function is adequate 2 Vocal cords plus anterior epiglottis seen 3 Vocal cords plus posterior epiglottis seen 4 Only vocal cords seen Success of First pass intubation outcome will be assessed right after fibreoptic guided intubation through LMA	—

Secondary

Measure	Time frame
1.To compare the proportion of failed to successful SAD placement in each group. 3. To compare the proportion of failed to successful intubation in each group. 2.To compare complications associated like sore throat & hoarseness of voice. Timepoint: 1.outcome will be assessed right after SAD placement.if more than two attempts are taken for placement then outcome will be declared as failure. 2.outcome of fibre optic guided intubation will be assessed right after intubation.if more than two attempts are needed for intubation then outcome is declared as failure. 3. Complications like sore throat & hoarseness of voice will be assessed after 1hour & 6hours postoperatively.	—
