Comparative assessment of I-gel and LMA Proseal for airway management in controlled hypertensive patients posted for short surgical procedures.

This study will mainly focus on comparing i-gel with LMA proseal regarding their airway management and pressor response in controlled hypertensive patients. Ethical clearance has been taken for this prospective,randomised, single blinded comparative trial that will be conducted in the Anaesthesiology dept of North Bengal Medical College and Hospital. Sixty patients of either sex, aged 20-60yrs, MPG I-II, controlled hypertensive will be included in the study after proper counselling and obtaining informed consent. Patients with anticipated difficult airway, risk of aspiration, recent history of sore throat and lung co-morbidity will be excluded from the study. Randomisation will be done by computer generated code in sequentially numbered sealed envelope. Study variables will include insertion time as primary outcome and others like number of insertion attempts, ease of insertion, fibre-optic grading of larynx, oro-pharyngeal leak pressure, hemodynamic responses (mean arterial pressure/ heart rate) before and after 1 min, 2min, 3min, and 5min post insertion of supraglottic airway device. Post-operative blood staining , sore-throat and dysphagia will also be studied.
