Anaphylactic reaction to thiopentone: a case report
Canadian Anaesthetists' Society Journal
|July 1, 1984
Summary
Anaphylaxis after anesthesia, potentially linked to thiopentone, occurred in a patient with prior uneventful anesthesia. Allergy testing confirmed thiopentone hypersensitivity, highlighting the need for careful anesthetic agent investigation.
Area of Science:
- Anesthesiology
- Immunology
Background:
- A patient with a history of multiple uneventful general anesthetics underwent a minor elective procedure.
- Preoperative assessment revealed no known drug allergies or prior adverse reactions to anesthesia.
Observation:
- Anaphylaxis developed rapidly after induction of anesthesia using thiopentone, Innovar, and gallamine.
- Successful resuscitation was complicated by ventricular fibrillation, followed by full recovery.
Findings:
- Subsequent allergy skin testing demonstrated specific hypersensitivity to thiopentone.
- The patient's reaction was attributed to an immune response to thiopentone.
Implications:
- This case underscores the importance of investigating suspected hypersensitivity to anesthetic agents, even after prior uneventful exposures.
- Guidelines for recognizing and managing anaphylaxis during anesthesia are crucial for patient safety.
- Thiopentone hypersensitivity should be considered in patients experiencing anaphylaxis post-induction.
