Which condition is a contraindication for SGA insertion?

An intact gag reflex serves as a contraindication for supraglottic airway (SGA) insertion because the presence of this reflex indicates that the patient has the ability to protect their airway. When a patient has an intact gag reflex, there is a significant risk that inserting an SGA could stimulate the reflex, leading to gagging, vomiting, or aspiration. In such cases, traditional airway management techniques that ensure proper airway protection should be prioritized.

In contrast, unconsciousness can sometimes be an indication for SGA use since unconscious patients typically lack the gag reflex and may benefit from having an airway maintained. Difficulty in ventilation can also justify SGA insertion as it may provide a better airway option when standard approaches fail. A low pulse rate, while it may suggest a problem with the patient’s overall condition, does not directly relate to the capability to ventilate or protect the airway, making it less relevant in this context.
