Abstract
Endotoxins (lipopolysaccharides, LPS) are potent bacterial poisons always present within the intestines in considerable amounts. Several pathophysiological conditions such as hypovolaemia, hypoxia, intestinal ischaemia, burns and radiation lead to a breakdown in the barrier and depending upon the extent of the injury, endotoxins enter the systemic circulation in increasing amounts. Antibiotics do not inactivate the endotoxins which continue to exert their toxic effects leading to nausea, vomiting, diarrhoea, fever, disseminated intravascular coagulation, vascular collapse and organ failure. When nonabsorbable antibiotics are given prior to the insult, systemic endotoxaemia is prevented. Immunotherapy, using anti-lipopolysaccharide IgG, inactivates plasma endotoxins, destroys gram-negative bacteria and opsonises them and may become a major form of therapy. An outline of endotoxin and anti-lipopolysaccharide and its importance to the anaesthetist and intensive care specialist is presented.
