The list of shock mediators currently comprises more than 150 candidates. A careful analysis using the criteria of Koch-Dale together with decision trees for exclusion of bias revealed that only histamine, C5a, beta-endorphin, tumor necrosis factor (TNF) thromboxane B2, platelet-activating factor (PAF), and oxygen free radicals are shown to be causally associated with shock symptoms. Although experimental studies with inhibitors of these mediators were convincing, there is still a lack of evidence under clinical conditions (exception histamine: anaphylactic shock). Combinations of antagonists against different causal mediators are the most promising future approaches.
