마취 중 Fentanyl 투여로 인한 알레르기 반응 -증례보고

Although rare, intraoperative allergic reaction can lead to significant morbidity and mortality. Clinical diagnosis is difficult as there is a need to differentiate from other causes of perioperative adverse reactions, such as side effects of administered drugs, or patients` medical conditions which may present with bronchospasm or hypotension. Intraoperative allergic reaction may be triggered by various agents. Among those, opioid-induced allergic reaction is scarcely reported. We report a case of a patient who has previously had allergic reaction to meperidine and intraoperatively showed fentanyl induced anaphylaxis or anaphylactoid reaction with literature reviews.
