Anaesthesia in septic patients: good preparation and making the right choice?

Abstract

Septic patients may require anaesthesia for surgery or to facilitate endotracheal intubation for respiratory failure. These patients frequently start with a deranged haemodynamic state, including vasodilation with hypotension, and cardiomyopathy, making induction of anaesthesia a potentially hazardous task. Anaesthetic agents are well known to decrease contractility and to cause vasodilation - in part from direct effect of the drugs, and in part due to the state of anaesthesia, that causes reduced sympathetic tone. Before induction, the physician should understand the haemodynamic state (especially using echocardiography), should restore cardiovascular reserve with inotropes and vasopressors..
