Clinical Issues-April 2022.

Area of Science:

• Allergy and Immunology
• Surgical Patient Care
• Infection Control

Background:

• Alpha-gal syndrome (AGS) is an allergic reaction to the alpha-gal carbohydrate found in mammalian meat and derived products.
• Patients with AGS may experience severe allergic reactions to medications and supplies containing mammalian-derived ingredients.
• Maintaining sterility in the operating room (OR) is paramount for preventing surgical site infections and managing patient allergies.

Purpose of the Study:

• To outline best practices for the perioperative care of patients with alpha-gal syndrome.
• To review strategies for maintaining sterile supplies and preventing contamination in the OR.
• To highlight the importance of controlling personnel traffic and environmental factors within the OR.

Main Methods:

• Review of current literature and guidelines on alpha-gal syndrome and operating room sterility.
• Analysis of potential sources of mammalian-derived ingredients in perioperative settings.
• Discussion of infection control principles related to sterile supplies and OR traffic.

Main Results:

• Patients with AGS require avoidance of mammalian-derived products, including certain medications and gelatin-based items.
• Overnight storage of sterile supplies necessitates specific protocols to maintain event-related sterility.
• Minimizing personnel traffic and optimizing airflow can reduce environmental contamination in the OR.

Conclusions:

• Comprehensive perioperative protocols are essential for safely managing patients with alpha-gal syndrome.
• Strict adherence to sterile techniques and environmental controls is vital in the OR.
• Further research may be needed to identify all potential mammalian-derived allergens in medical supplies.
