OBJECTIVES: To retrospectively assess the incidence and severity of perioperative protamine reactions in adult patients with documented history of fish allergy.
DESIGN: Retrospective observational study.
SETTING: Large academic tertiary referral center.
PARTICIPANTS: Adults with fish allergies undergoing surgeries involving protamine, between January 1, 2008, and March 1, 2018.
INTERVENTIONS: Perioperative protamine administration in patients with documented fish allergy.
MEASUREMENTS AND MAIN RESULTS: Perioperative protamine and anaphylactic reactions were reviewed. A diagnosis of anaphylaxis or protamine reaction was based on clinical suspicion, perioperative events, and postoperative evaluations. Among 214 patients, 2 cases (<1%) of anaphylaxis or protamine reactions occurred. Cardiac procedures were most common (67%). The median intraoperative heparin dosage was 46,000 IU, and the median protamine dosage was 310 mg. Nearly all patients (99%) were admitted to the intensive care unit postoperatively, with a median hospital stay of 6.5 days (interquartile range, 5.2-14.6 days). There were 3 deaths (1%) within 30 days, and 15 (7%) within 1 year.
CONCLUSIONS: The study findings suggest that in patients with a history of fish allergy, cross-reactivity with protamine is unlikely, as anaphylaxis and/or protamine reactions were rare in this patient population in the perioperative environment. Based on these findings, this study does not recommend avoiding protamine solely based on a history of fish allergy when heparin reversal is required during surgery.
