   Introduction
 
With increasing life expectancy and improved surgical technology an ever-larger number of elderly patients with cardiovascular disease, or significant cardiovascular risk factors will undergo major surgery. More than 5% of an unselected surgical population undergoing non-cardiac surgery will suffer from perioperative cardiovascular complications including myocardial infarction and cardiac death. The incidence of adverse cardiac events may even reach 30% in high-risk patients undergoing vascular surgery causing a substantial financial burden of perioperative health care costs.59 Thus, all therapeutic measures should be undertaken to reach the challenging goal of a lower incidence of perioperative cardiovascular complications.

Gaining control over sympathetic nervous system activity, that is blunting the adrenergic response to the surgical trauma, traditionally represents an important aspect of anaesthetic practice.21 Anaesthesiology has been regarded as the ‘practice of autonomic nervous system medicine’. While variable and moderate changes in sympathetic nervous system activity function as a servo-control mechanism and are even . . . [Full Text of this Article]
