Cylinder & Anesthesia Machine
The narrowest part of larynx in infants is at cricoid level. In administering anaesthesia this may lead to all, except:
|A||Choosing a small size tube|
|B||Trauma to subglottic region|
Choosing a small size tube
a. The subglottis is the narrowest part in children.
b. The implication of this is that uncuffed tubes should be used. Choosing appropriate size tube is very important in children to prevent aspiration (as uncuffed tubes increase the risk of aspiration) so a small size tube should never be chosen.
c. Trauma to subglottic region may cause laryngeal edema and postoperative stridor.
