Tonic clonic convulsions induced by low dose intrathecal bupivacaine and intraurethral lidocaine gel

ABSTRACT

Local anesthetics are commonly used as analgesic and anesthetics. The systemic toxicity of local anesthetics involves CNS and cardiovascular system. Grand mal seizure, as a critical event may occur during toxicity due to high doses, rapid entry of local anesthetic into the systemic circulation and erroneous injection of local anesthetics through the intravenous route. We would like to present a case that experienced tonic clonic convulsion in spite of administration of low dose intrathecal bupivacaine and intraurethral lidocaine gel
