“…Over the past decades numerous publications originating from various medical disciplines dealt with problems of release of biogenic amines (histamine, catecholamines, serotonin) in response to any kind of stress (Schayer 1961, Erspamer 1966; Rocha e Silva 1966; Blaschko and Muscholl 1972;Altura and Halevy 1978;Vane and Ferraira 1978). Their role in general cardiovascular reactions like tachycardia, arrhythmia, hypotension and in microcirculatory responses such as oedema, thrombosis and hypoxic tissue damage is still poorly understood, but for obvious reasons these questions are of major interest in surgery.…”

Summary.A prospective controlled clinical trial was conducted on changes in plasma histamine and catecholamine levels during 5 standard operations. This communication, as the first part of the trial, deals only with the feasibility of such a trial and the changes in plasma histamine levels.Elevated histamine concentrations corresponding to histamine-release responses of > 1 ng/ml occurred in 8 of 25 operations. In an explorative analysis these reponses were associated with distinct phases of anaesthesia or the surgical procedure.Blood transfusion carried the risk of infusion of "free histamine" into the patient -especially when administerea under pressure.Since during operations "free histamine" enters the circulation with a rather high incidence and may cause harmful effects, premedication with Hl-+Hz-receptor antagonists seems worth consideration.Key words: Standard operations anaesthesia -blood transfusion -plasma histamine Plasmahistaminspiegel bei Patienten im Verlauf von versehiedenen Standardoperationen: Einflufl yon An/isthesie, chirurgisehem Trauma und BluttransfusionZusammenfassung. Eine prospektive kontrollierte klinische Studie wurde fiber Ver/inderungen des Plasmahistamin-und Katecholaminspiegels bei 5 Standardoperationen durchgeffihrt. Diese Mitteilung, als erster Teil der Studie, zeigt nur die M6gtichkeiten auf, eine solche Studie durchzuf/ihren und Ver/inderungen des Plasmahistaminspiegels nachzuweisen.Erh6hte Plasmahistaminkonzentrationen, die einer Histaminfreisetzungsreaktion yon > 1 ng/ml entsprechen, kamen bei 8 yon 25 Operationen vor. In einer explorativen statistischen Analyse wurden diese Reaktionen mit bestimmten Phasen der An/isthesie oder des chirurgischen Eingriffs in Verbindung gebracht.Bluttransfusionen tragen das Risiko in sich, ,,freies Histamin" in den Patienten zu infundieren -zumal bei Filterpassage, wenn es unter erhthtem Druck angewandt wird.
