Findings of the neuromuscular blocking agent rocuronium in blood from deceased subjects several months after exposure: A report of two cases.

Rocuronium is a neuromuscular blocking agent mainly used in anesthetic procedures. Two patients who died 53 and 76 days, respectively, after their last rocuronium exposure had low (0.002-0.007 mg/L) levels of the drug in femoral blood, urine and vitreous humor samples obtained at autopsy. In neither case, the cause of death was related to the exposure to rocuronium. Here, these two cases are presented and the implications of the findings discussed.
