<p>Intraoperative anaphylaxis to gelatin-based hemostatic agents: a case report</p>

Abstract

Surgiflo Haemostatic Matrix is an absorbable gelatin matrix hemostatic material that has been widely used in various surgical operations to assist hemostasis. Nonetheless, as biologically active agents (contains porcine gelatin), there is potential for allergic reactions to these products. Here, we report the case of a 71-year-old man who had intraoperative anaphylaxis with cardiovascular events to gelatin associated with the use of a topical hemostatic agent (Surgiflo). The patient reported a history of red meat allergy and tick bites during his allergological examination after anaphylaxis. He also had high levels of specific IgE antibodies towards alpha-gal. Special consideration should be given before administering bovine- or porcine-derived gelatin products during surgery to patients with animal-related allergies, such as alpha-gal or gelatin allergy and an atopic background.
