Abstract Histamine release events were shown in a prospective randomized controlled trial in patients undergoing elective general surgery with an extraordinarily high incidence: 73 per cent. This high incidence was explained by several factors: — the sample size which was much greater than in previous studies — the improved plasma histamine assay — the precise definition of histamine release in clinical conditions and its measurement at the top of Bateman functions — the standardized induction of anaesthesia and preparation of the surgical patient — and finally the considerable number of cancer patients since more than 60% of the reactions 〉5 ng/ml occurred in this group which comprised only 20% of the study population. Two cases of life-threatening anaphylactoid reactions occurred in this trial corresponding to an incidence of 1 per cent. This was — again — very high compared to previous epidemiological studies. Both cases were again cancer patients and occurred in the placebo group — information given by the external study advisory group for further treatment of the individual patient. The data on the high incidence of histamine release including the high incidence of life-threatening reactions favourrationally a preoperative H1 −+H2-prophylaxis with the drugs used in this study: dimetindene and cimetidine. The question of the incidence was one of the unsettled problems which led to this trial. Analysis of the first 180 patients already answered this question more than we had ever expected.
