Recurrent perioperative anaphylaxis in a 54-year-old man

Area of Science:

• Anesthesiology
• Immunology
• Critical Care Medicine

Background:

• Perioperative anaphylaxis, a severe allergic reaction during surgery, occurs in 1 in 5,000 to 20,000 cases.
• Mortality rates for perioperative anaphylaxis can reach up to 9%.

Observation:

• Determining the precise cause of anaphylaxis during general anesthesia is difficult due to the numerous medications administered rapidly.
• Antibiotics and anesthetics are frequently implicated in precipitating these severe allergic reactions.
• Recurrent anaphylaxis episodes were observed in a patient undergoing vital cardiac surgery.

Findings:

• The case highlights the diagnostic challenges in identifying the specific allergen responsible for anaphylaxis in the perioperative setting.
• Multiple factors, including anesthetic agents, antibiotics, other perioperative exposures, and patient-specific risk factors, contribute to anaphylaxis.

Implications:

• This case underscores the need for vigilant monitoring and prompt diagnosis of anaphylaxis in surgical patients.
• Improved diagnostic strategies are crucial for managing recurrent anaphylaxis and optimizing patient safety during complex procedures.
• Understanding the multifactorial etiology of perioperative anaphylaxis is essential for preventing future occurrences.
