Intraoperative Anaphylaxis to Gelatin during Alveolar Bone Grafting for Cleft Palate

Abstract

Summary:. Intraoperative anaphylaxis can be life threatening. Anaphylaxis to gelatin-based topical hemostatic agents is an underrecognized hypersensitivity. To date, only 21 cases of intraoperative anaphylaxis have been reported for gelatin-based hemostatic agents. In this article, we report the case of a 10-year-old male patient who sustained anaphylaxis after the use of Gelfoam during harvest of a bone graft. Rapid diagnosis and treatment of intraoperative anaphylaxis is imperative to prevent adverse outcomes. Referral to an allergist for identification of the allergen and appropriate notation in the medical record are paramount to avoid future anaphylactic events. Surgeons should avoid gelatin-based hemostatic agents, such as Gelfoam, in patients with reported intolerance of gelatin-based foods and medicines.
