Brief Summary
Patients aged 19 to 78 years with ASA status I-II scheduled for elective surgery under general anesthesia, were recruited and randomized into two groups, Group A (BlockBuster) and Group B (Proseal-LMA). Anesthesia induction for both groups was standardized with no paralysis given. Supraglottic airway (SGA) insertion (either Blockbuster or Proseal-LMA) was executed by a single experienced investigator. The investigator inserted the BlockBuster in Group A patients and the Proseal-LMA in Group B patients. These parameters were compared between the groups; the number of attempts, time taken to achieve successful insertion, oropharyngeal leak pressure (OLP), fiberoptic view of SGA position, hemodynamics changes and complications from the insertion.

Outcome Measures
Primary Outcomes (1)
Oropharyngeal leak pressure measurement to assess efficacy of airway seal by the supraglottic airway device
Oropharyngeal leak pressure (OLP) was assessed by setting the adjustable pressure-limiting (APL) valve of the circle system at 30 cmH2O with a fresh gas flow of 3L/min. The OLP was determined by observing the airway pressure at equilibrium until an audible noise was heard over the mouth with a stethoscope. The measurement unit is cmH2O. For safety reasons, the OLP was kept below 40 cmH2O.
