Palonosetron-Induced Anaphylaxis During General Anesthesia: A Case Report

초록

Palonosetron is a 5-hydroxytryptamine-3 (5-HT-3) receptor antagonist used for preventing postoperative nausea and vomiting. Compared with on-dansetron and granisetron, it is a better drug because of prolonged action and minimal side effects. Some adverse effects of palonosetron have been reported. In this report, we describe a 37-year-old male who developed severe hypersensitivity reactions to palonosetron during surgery for kidney donation. His medical history was unremarkable, except for inguinal hernia with herniorrhaphy 8 years ago. The surgery was uneventful until 2 hours 20 minutes. After palonosetron injection, his blood pressure dropped to 80/50 mmHg, and facial edema, rash, conjunctival swelling, and wheezing developed. The patient was resuscitated by administration of ephedrine, hydrocortisone, and peniramine. Following the surgery, the patient was monitored for 3 days, and there were no subsequent anaphylactic reactions or other complications. The skin test on postoperative day 54 was positive for hypersensitivity to palonosetron. Although palonosetron is known for its safety, other hypersensitivity events have been reported. Ondansetron is another widely used 5-HT-3 antagonist, which has been reported to cause anaphylaxis. Therefore, clinicians should be aware of the possibility of patients experiencing severe adverse reactions to palonosetron.
