Transient Stroke-Like Symptoms Following Subcutaneous Lidocaine Administration: A Case Report.

Transient neurological symptoms can occasionally occur as a complication of procedures involving the use of the local anesthetic lidocaine. The present report outlines a case of a patient who developed acute but self-limited neurological symptoms following subcutaneous lidocaine administration for a minimally invasive outpatient procedure. Shortly after receiving 20 cc of lidocaine, she experienced slurred speech that resolved within 30 minutes. Neuroimaging did not reveal any evidence of acute pathology. This case highlights a rare instance of transient neurological symptoms following lidocaine administration, underscoring the need for clinician vigilance and preventive strategies during local anesthetic use.
