Study Overview
Brief Summary
Supraglottic airway tools, one of the tools used in the management of the difficult airway. American Society of Anesthesiologists and the Difficult Airway Society of the United Kingdom airway management algorithms have included the LMA. In our study investigators aimed to determine which one will show the best performance with supraglottic airway means that LMA - Classic, LMA - Flexible and LMA - ProSeal in patients that difficult airway scenarios created with attaching collar.
