Lidocaine toxicity secondary to local anesthesia administered in the community for elective circumcision

Abstract

We report three previously healthy infants aged, respectively, 23 days, 6 weeks, and 3 months with systemic lidocaine toxicity following administration of subcutaneous lidocaine for regional anesthesia during an elective circumcision. The patients developed a generalized seizure requiring endotracheal intubation but recovered fully with supportive care. We report the clinical details of these cases as well as a review of lidocaine toxicity.
