摘要:

The peripheral circulation substantially contributes to the maintenance of blood pressure. The importance of neural reflexes in maintaining vascular tone is discussed. In addition, the role of endothelial-derived vasoactive factors in modulating vascular smooth muscle is reviewed. Both regulatory systems can be compromised by pathologic processes and by anesthetics.

摘要:

As older patients continue to need non-cardiac surgical procedures, we as anesthesiologists will continue to provide care for the patient with coronary artery disease. This review focuses on the patient with ischemic disease undergoing non-cardiac surgery. Particular emphasis is given to advances in drug therapy for this population.

摘要:

Inter-related and interdependent pathophysiological adaptations combine to create the clinical problem of essential hypertension. This review outlines the continuing work on vascular neuroeffector mechanisms, the use of modern molecular biological techniques, and the role of the endothelium in the regulation and generation of hypertension. Current anti-hypertensive strategies have introduced calcium antagonism and angiotensin-converting enzyme inhibition to the frontline of attention. The demonstration of organ-specific auto-antibodies in dilated cardiomyopathy introduces an exciting era of immuno- and anti-viral chemotherapy.

摘要:

Perioperative cardiac morbidity remains an important contributor to outcome after non-cardiac surgery, and a plethora of studies have examined factors important in determining outcome in patients with pre-existing cardiovascular disease. This article reviews the most recent work which has examined the role of preoperative clinical assessment to identify subsets of high-risk patients where preoperative testing, special monitoring or therapy may help reduce perioperative morbidity. These data suggest that simple clinical assessment, although not ideal if used alone, when combined with additional non-invasive as well as invasive studies, remains an important element in the comprehensive perioperative management of these patients. Future studies will need to define the optimal method of preoperative risk assessment in clinical practice.

摘要:

The predictive value of both individual risk factors, particularly prior myocardial infarction and preoperative myocardial ischemia, and multi-variate models for postoperative cardiac morbidity are examined in non-cardiac surgery patients. Preoperative stress and dipyridamole testing help delineate those at greatest risk, although the population studied impacts on the test's predictive value.

摘要:

The review highlights recent advances in the management of patients presenting for carotid endarterectomy and abdominal aortic aneurysm resection. The review includes new insights into the pathogenesis of aortic aneurysm formation, new preoperative risk management strategies, new non-invasive cardiovascular monitoring techniques for these procedures as well as outcome data based on large prospective multicenter studies.

摘要:

Exacerbation of existing or new cardiac arrhythmias in anesthetized patients is attributed to acutely altered normal or abnormal cardiac electrophysiology, the understanding of which is fundamental to effective prevention and management. Electrocardiography provides the means for detection and diagnosis of arrhythmias and altered electrophysiology. Advances concerning these topics are discussed in this review.

摘要:

Children who survive repair of structural defects and adults with artificial valves continue to present special challenges to anesthesiologists. Several problems, including endocarditis, mitral valve prolapse, and general anesthesia for patients with aortic stenosis have been re-examined, and are reviewed here.
