What is a contraindication for using oral glucose in an adult patient with altered mental status?

Using oral glucose in a patient with altered mental status is primarily contraindicated if the patient is unable to swallow. This is crucial because oral glucose is intended to be taken by mouth to raise blood sugar levels, and if the patient cannot swallow, there is a significant risk of aspiration. Aspiration can lead to choking or pneumonia, which can further complicate the patient’s condition.

In patients with altered mental status, the ability to protect their airway is often compromised. Therefore, administering oral glucose in such cases could do more harm than good. It is essential for EMTs to assess the patient’s level of consciousness and ability to swallow before considering the administration of oral glucose.
