A Comparison of blind intubation with fiberoptic guided intubation through Blockbuster(TM) Laryngeal Mask Airway using PolyVinylChloride Tube in Adults

This study is randomized, double blind parallel group trial to compare Blind intubation with Fiberoptic guided intubation through Blockbuster laryngeal mask airway using polyvinylchloride tube in adults patient that will be conducted at Department of Anaesthesiology & Intensive Care, Safdarjung Hospital and Vardhman Mahavir Medical College, New Delhi for 18 months after seeking clearance from Institutional Ethics Committee. This study includes patients belonging to ASA Grade I & II aged between 18yrs to 60yrs of both genders undergoing elective surgery of less than 3 hours anticipated duration of surgery requiring General Anaesthesia with orotracheal intubation with supine postion intraoperatively. The primary outcome measures the first pass success rate of blind intubation with that of fiberoptic guided intubation through blockbuster LMA. The secondary outcome will be measuring endotracheal tube insertion characteristics i.e. ease of insertion, number of attempts for successful intubation, time taken for intubation, manuevers required for tube insertion & will also measure hemodynamic changes i.e. Blood Pressure change(Systolic BP/Diastolic BP), Heart rate changes, oxygen saturation changes. We hypothesise from this study that the blind intubation is similar to fiberoptic guided intubation through blockbuster LMA using PolyVinylChloride Tube in adults.
