Summary

Ability to provide oxygen to patients undergoing general anaesthesia is crucial. This is traditionally provided using face mask, supraglottic airway (breathing tube above voice box) or endotracheal tube (breathing tube in wind pipe). However in some patients it may be impossible to provide oxygen through any of these above means which can be life threatening and lead to permanent brain damage/death. One of the ideal ways of managing this emergency situation is to pass a breathing tube through a membrane in the front of the neck called cricothyroid membrane with the neck in extension position where permitted. Many studies have recommended identifying the cricothyroid membrane before general anaesthesia in high risk patients but with their head in neutral position. This study will be a pilot study to check if the cricothyroid membrane remains in the same place in neutral and extended positions.
