Topical lidocaine improves conditions for laryngeal mask airway insertion

Purpose We hypothesized that optimal laryngeal mask airway (LMA™) insertion conditions might be achieved with topical lidocaine and a smaller dose of propofol. In this study, insertion conditions after topical lidocaine 40 mg followed by propofol 2 mg·kg−1 were compared with propofol 2 mg·kg−1 or propofol 3 mg·kg−1 alone.
