[Anaphylactic shock after a test-dose of aprotinin in pediatric orthopedic surgery]

Abstract

A case of severe anaphylactic shock in a 28-month-old child following a testing-dose of aprotinin during major orthopaedic surgery is reported. Two months earlier, aprotinin had been administered during a similar controlateral surgical procedure. The grade III anaphylactic accident required a 48 h treatment in an intensive care unit. The outcome was favourable. The pin-prick tests were positive for aprotinin, substantiating the diagnosis of anaphylactic shock, whereas the test with specific IgE was negative. The value of current diagnostic tools for aprotinin allergy is discussed. The administration of a testing-dose in a patient previously treated with aprotinin cannot be recommended. Considering the risk for allergy, aprotinin should only be administered for recognized indications such as major orthopaedic surgery. Before any readministration of this agent an assessment by an allergist-anaesthetist is essential for determination of the risk-benefit ratio.
