Abstract
We report a case with transition to complex regional pain syndrome (CRPS) caused by nerve injury associated with crush syndrome. The diagnosis was delayed because of coma due to acute drug poisoning. A 44-year-old man had attempted suicide by taking massive amounts of psychotropic drugs 2 days earlier and was transported to our hospital by ambulance. His arms had been compressed due to the prolonged (2 days) consciousness disturbance, and he experienced non-traumatic crush syndrome and rhabdomyolysis. Acute renal failure was prevented with massive infusion and hemofiltration. However, he experienced muscle and nerve injury at the compressed area, which presumably led to CRPS. In cases of suspected crush syndrome associated with acute drug poisoning, it is also important to recognize the possibility of developing CRPS.
