What is a potential risk of placing a tongue blade in the mouth of a child suspected of having epiglottitis?

The risk of obstruction is a significant concern when considering the use of a tongue blade in a child suspected of having epiglottitis. Epiglottitis is an inflammatory condition that causes swelling of the epiglottis, which can lead to airway obstruction. Inserting a tongue blade can inadvertently provoke further swelling or irritation of the inflamed tissue, potentially leading to a complete or partial blockage of the airway.

In this scenario, it is crucial to minimize any intervention that could exacerbate the condition or worsen the airway compromise. The priority in cases of suspected epiglottitis is to ensure that the airway remains open and support is available for potential intubation or emergency intervention if needed. Thus, the decision to avoid a tongue blade is based on the high stakes associated with airway management in this context.
