A Case of Anaphylaxis during Anesthesia Caused Twice by Rocuronium Bromide.

: A 49-year-old woman was scheduled for endoscopic cholecystectomy under general anesthesia in another hospital. The anesthesia was performed by a surgeon, but the operation was cancelled because of anaphylac- tic shock, and the surgeon performed emergency treatment Afterward, the surgeon declined operation, and she could not receive medical treatment. She visited our hospital for complete examination and 'operation. Drug-induced lymphocyte stimulation test (DLST) and standard perioperative test results were almost normal, and we could not find the cause of anaphylaxis preoperatively. After induction of anesthesia, the erythema ap- peared with hypotension and tachycardia. She was responsive to symptomatic treatment such as transfu- sion, antihistamine agent and streroid administration. After the recovery from the shock state, the operation proceeded without complications and she recovered from anesthesia uneventfully. She had no major post- operative complication.
