The Australian Incident Monitoring Study. Clinical anaphylaxis: an analysis of 2000 incident reports

There were 57 reports of possible allergic reactions in the perioperative period in the first 2000 incidents reported to the Australian Incident Monitoring Study. These were examined and classified with respect to presentation, clinical course, agents implicated and management strategies employed. Reactions were graded as to probability of allergic aetiology and severity of systemic disturbance. Two deaths were reported. A method of determining an "allergy score" was devised as an indication of which reactions may be most deserving of further investigation.
