The document is a narrative review comparing the risks of complications associated with the use of laryngeal mask airways (LMAs) versus endotracheal tubes (ETTs) during general anesthesia in pediatric patients with upper respiratory infections (URIs). It highlights that LMAs are associated with a lower risk of respiratory complications compared to ETTs, suggesting their preference in such cases. Additionally, it introduces an Upper Respiratory Infection Screening Tool and a Management Algorithm to assist anesthesia professionals in assessing and managing children presenting for surgery with URIs.

What is the main disadvantage of the laryngeal mask airway?

The advantages of LMA compared to tracheal intubation are no tracheal injury during tube installation and removal, less airway stimulation, less invasion of the airway tissue, easier installation, and efficient establishment (6-9).

What is possible complication from using an LMA?

The major disadvantage to LMA devices is that it does not protect the airway from aspiration. Given that most patients in the ED will have full stomachs, LMAs are considered only a temporizing measure until a definitive airway is secured (i.e cuffed ETT in trachea).

Why is LMA preferred over ETT?

Laryngospasm, nausea, vomiting, arytenoid dislocation, vocal cord paralysis, sore throat, and cough were considered as complications of using LMA. The medical files of those patients undergoing surgery were evaluated and those cases operated on with LMA were identified.
