Do cross-food allergies to propofol exist?

Alergia a la comida; Sensibilización alimentaria; PropofolFood allergy; Food sensitization; PropofolAl·lèrgia alimentària; Sensibilització alimentària; PropofolBackground: Propofol is a short and rapidly acting intravenous anesthetic extensively used for the induction and maintenance of general anesthesia. It is a lipid emulsion that contains soybean oil, purified egg phosphatide, and egg lecithin. Therefore, the package leaflet indicates that its administration is contraindicated in patients allergic to soy, eggs, or peanuts. Our study aimed to determine whether patients with proven food allergies are allergic to propofol. Methods: Patients of all ages allergic to soy, eggs, or peanuts who agreed to undergo skin testing for propofol allergies were included. The subjects first underwent a skin test to confirm food allergies. If candidates were negative, they were excluded. If the result was positive, a propofol skin test was performed. Results: Sixty-four patients with confirmed food allergies underwent a propofol skin test. Only one was positive in the propofol skin test (1.6%). The patient was allergic to peanuts and soybeans. These results reinforce the idea that there is no justification for avoiding propofol use in these subjects. Conclusions: Propofol can be safely administered to patients allergic to soy, eggs, or peanuts. We recommend caution in patients with a history of anaphylaxis after ingestion of the above-mentioned foods
