What should be done if a patient experiences an allergic reaction to a local anesthetic?

The appropriate response when a patient experiences an allergic reaction to a local anesthetic is to discontinue the procedure, call for medical assistance, and provide appropriate treatment. This approach is essential because allergic reactions can escalate quickly and lead to serious complications, such as anaphylaxis, which may require immediate medical intervention.

Discontinuing the procedure ensures that no further allergens are introduced, which could worsen the reaction. By calling for medical assistance, healthcare professionals can ensure that the patient receives the necessary medical evaluation and treatment, which may include antihistamines, corticosteroids, or even epinephrine depending on the severity of the reaction. Providing appropriate treatment in a controlled medical environment minimizes risks and ensures patient safety.
