Local Anesthetic Systemic Toxicity Following Infraclavicular Nerve Block Under Ultrasound Guidance

Aims and The infraclavicular nerve block as a method for anesthesia or analgesia in upper extremities that can be performed under guide of nerve stimulation or ultrasound. One of the adverse reaction to this method is the local anesthetic systemic toxicity that has been decreased when using the ultrasound to avoid intravascular injection.
Case report: This case report explains an infraclavicular block under guide of ultrasound in a 52-year-old patient who was experienced local anesthetic systemic toxicity with lidocaine due to anomalous vasculature that normally cannot be visualized in ultrasound guide. The epilepsy was controlled by barbiturate and after one day, he was discharged.
