[Case of anosmia which appeared after anaphylactic shock due to intravenous heparin].

A patient developed anaphylactic shock after a heparin dosage during an operation to make inner shunt for chronic renal failure of Alport syndrome. The operation was canceled and the patient was admitted to the ICU with tracheal intubation. He was extubated safely on the fifth postoperative day, but he lost the sense of smell from the day after. Abnormality of the nasal mucosa was not recognized. The smell disorder improved slowly in three or four weeks. Anosmia after anaphylactic shock is very rare, but we should be careful for this complication after anaphylactic shock.
