What should be done if a patient experiences hives after receiving local anesthesia?

When a patient develops hives after receiving local anesthesia, it indicates a potential allergic reaction. Hence, it is crucial to monitor for further signs of an allergic reaction. This step involves observing the patient for additional symptoms such as swelling, difficulty breathing, or changes in heart rate, which could indicate a more severe reaction like anaphylaxis.

Monitoring is essential because it helps determine the severity of the patient's response and guides the decision-making process regarding further treatment. If the reaction escalates, immediate interventions may be required. All healthcare providers must remain vigilant in assessing these changes, as the health and safety of the patient are paramount.

Other options, such as continuing treatment as normal or administering more anesthetic, may exacerbate the patient's condition and risk severe complications. Stopping the procedure and providing hydration may not be adequate without proper monitoring and intervention, as hydration alone does not address the allergic response. The correct approach prioritizes patient safety by focusing on careful observation and assessment of the allergic reaction’s progression.
