[Anaphylactic shock following topical use of thrombin for irrigation of urinary bladder].

A 55-yr-old male with carcinoma of bladder received transurethral coagulation (TUC) under epidural anesthesia. A few min after the operation, he went into anaphylactic shock during irrigation of urinary bladder with thrombin solution. The symptoms were epigastralgia, circulatory collapse, skin rashes over the whole body and dyspnea. Oxygen inhalation and iv administration of epinephrine and steroid were performed, and his general condition improved within several hours. On the 2nd day after recovery from the anaphylactic shock, the patient received prick test on several agents which he had been given during operation. Prick test and RAST (radioallergosorbent test) on thrombin were positive. Based on our experience, thrombin may act to produce anaphylactic reaction. Although anaphylactic shock following topical thrombin is rare, we feel that thrombin should not be used without prick test.
