Topical hemostatic agents are commonly used in a wide variety of surgical procedures to assist in hemostasis. However, the use of these agents is not without risk as many contain biologically active agents derived from human and animal products that have the potential to cause adverse reactions. This case report covers a 44-year-old man with a history of alpha-gal syndrome who was scheduled for an open reduction and internal fixation of a left distal radius fracture. Alpha-gal syndrome is characterized by an IgE-mediated type 1 hypersensitivity reaction to a mammalian oligosaccharide epitope. Patients with this condition have a history of a past tick bite and subsequent development of an allergic reaction to mammalian protein products, most notably red meat. The patient had concerns about products used during surgery and potential reactions based on his allergy. The intent of this case report is to promote physician awareness of the widespread use of mammalian products in surgical hemostatic agents and potential immunogenic reactions. By increasing awareness of the alpha-gal syndrome, the goal is that medical device companies will actively disclose product components that could potentiate these adverse reactions and continue to develop alternative agents.
