ABSTRACT
A 73-year-old man (164cm height 51 kg body weight) with a history of Parkinson's disease and dementia was scheduled for a cervical lymph node biopsy under general anesthesia. We induced anesthesia with thiamylal and fentanyl, and maintained with sevoflurane and remifentanil without any incident. The patient did not emerge from anesthesia after the surgery. He developed coma and did not respond to painful stimuli. However, his breathing was spontaneous with stable hemodynamics. Although naloxone was given, he was still comatose. His clinical neurological findings showed no organic abnormalities. Forty minutes after the surgery, he suddenly woke up and followed instructions. We learned that previously he had been diagnosed with dementia with Lewy bodies.

We encountered three cases of perioperative anaphylaxis identified by using skin-prick tests. [Case 1] A 43-year-old woman was scheduled to undergo elective laparoscopic subtotal gastrectomy under general anesthesia for gastric tumor. However, the procedure was cancelled because of anaphylaxis that was noted at the beginning of the surgery. We performed a skin-prick test and observed a positive reaction with ro- curonium. [Case 2] A 79-year-old man underwent laparoscopic colon resection under general anesthesia for colon cancer. Anaphylaxis was noted at the end of surgery. We performed a skin-prick test and observed a positive reaction with sugammadex. [Case 3] A 44-year-old woman underwent myomectomy under general anesthesia for a uterine fibroid. Anaphylaxis was noted approximately 10 minutes after the beginning of surgery. We performed a skin-prick test and noted a positive reaction with latex. It is difficult to identify the reason for anaphylaxis during surgery under general anesthesia because various agents may be responsible for the anaphylactic reaction. Anaphylaxis during surgery is a rare but life-threatening event and it is important to identify the causative agent for anaphylaxis.
