Local anesthesia toxicity in occipital nerve block: A case of generalized tonic-clonic convulsions

Abstract

We present a case of local anesthesia toxicity resulting in generalized tonic-clonic convulsions following an occipital nerve block procedure. A 42-year-old female patient underwent an occipital nerve block procedure for her persistent daily headaches. Shortly after the injection, she experienced an episode of generalized tonic-clonic seizure. Prompt recognition and management led to the resolution of the attack without any residual neurological sequelae. This case highlights the importance of vigilance during occipital nerve blocks, early identification of potential adverse events including seizures albeit rare and appropriate management of local anesthesia toxicity accordingly
