Comparing the Clinical Performance of BlockBuster vs Proseal-LMA in Unparalysed Patients Undergoing General Anesthesia

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.
