Lethal Self-Administration of Atracurium: A Rarely Reported Case with Review of Literature.

Atracurium besylate is a nondepolarizing skeletal muscle relaxant first introduced in 1980. It is used during endotracheal intubation. It causes muscle relaxation during surgery or mechanical ventilation. When people consider suicide, they employ drugs found in their surroundings but not usually injectable muscle relaxants, which are not widely available. Studies on their use in suicide are rarely reported worldwide. This was a case of a 34-year-old male nursing staff, working in the general surgery department's operation theater complex, who was found unconscious in bed in his room in the morning with an empty syringe by the bedside. He was declared dead when brought to the emergency department. Forensic autopsy was conducted, and during the external examination, a needle puncture wound was found over the left cubital fossa. No other external other injuries were observed throughout the body. The toxicological analysis report indicated the presence of laudanosine in the vitreous humor, blood, urine, and skin from the puncture site and underneath vein. Also, the toxicological analysis of the empty syringe found at the crime scene revealed the presence of atracurium, confirming that the victim had administered a lethal dose of atracurium.
