A rescue technique for LMA Classic insertion in unanticipated limitation of mouth opening

Abstract

Sudden unanticipated limitation in mouth opening can cause serious problems in airway management. We report a case in which mouth opening became restricted after induction of anaesthesia resulting in inability to insert LMA Classic by standard insertion technique. An alternative technique consisting of LMA insertion without intraoral manipulation was used in this case as a rescue technique and LMA could be inserted successfully.
