A patient experienced acute heart failure after two protamine administrations, despite no prior allergy history. This case highlights potential predispositions and suggests strategies to mitigate protamine adverse reactions.

Area of Science:

  • Cardiology
  • Anesthesiology
  • Pharmacology

Background:

  • Protamine is used to reverse heparin anticoagulation during cardiac surgery.
  • Adverse reactions to protamine can range from mild to severe, including anaphylaxis and cardiovascular compromise.

Observation:

  • A 68-year-old woman with no known allergies developed acute heart failure following two separate administrations of protamine.
  • The patient underwent open heart surgery, a procedure where protamine is commonly used.

Findings:

  • The patient's history suggests a possible predisposition to severe adverse reactions to protamine.
  • The recurrent nature of the reaction indicates a potential hypersensitivity or idiosyncratic response.

Implications:

  • This case underscores the importance of considering protamine hypersensitivity in patients with unexplained cardiovascular events post-cardiac surgery.
  • Further investigation into patient-specific risk factors and alternative heparin reversal strategies may be warranted.
  • Developing improved screening methods and desensitization protocols could enhance patient safety during procedures requiring protamine.
