The anaesthetic management of patients in haemorrhagic shock is described. The principles are those of initial resuscitation with electrolyte solutions and alleviation of metabolic acidosis, combined with early induction of anaesthesia to permit control of bleeding as soon as possible. The anaesthetic technique depends on pre-oxygenation, intravenous anaesthesia, muscular relaxation and ventilation with pure oxygen. Earlier cases were induced with thiopentone and maintained with intermittent suxamethonium, but intravenous ketamine was later employed for induction and intramuscular ketamine for maintenance; this use of ketamine is now the author's method of choice. The use of a central venous pressure line connected to a cannula in the internal jugular vein is recommended.
