What is a common risk associated with administering oral glucose?

Administering oral glucose carries the risk of aspiration primarily because it is a thick, syrupy substance that can be difficult for a patient to swallow. If the patient is not fully conscious or has a diminished level of consciousness, there is a substantial risk that they may be unable to protect their airway effectively. This could lead to the glucose entering the airway instead of the esophagus, potentially causing aspiration pneumonia or other respiratory complications.

In cases where patients are alert and responsive, the risk is significantly reduced, but caution should always be exercised, especially with those who have altered mental status. Ensuring that patients can swallow safely is critical when considering the administration of oral glucose in emergency situations.
