Postoperative perfusion deficits.

Abstract

The three keys to successful recovery of the critically ill postoperative patient are: (1) in-depth preoperative assessment and risk evaluation; (2) review of intraoperative course and evaluation of risk for perfusion deficit; and (3) diligent postoperative monitoring for early onset of perfusion deficit. Complications arise when metabolic demands exceed the body's ability to supply essential nutrients. The choice of treatment modality is related to the cause of perfusion deficits. Decreased preload and afterload is treated with fluid and vasopressor therapy. Increased preload is best managed by diuretics and venous dilation. Afterload reduction is accomplished with vasodilator therapy and decreases in sympathetic stimulation. Contraction is enhanced with inotropic therapy and management of preload and afterload within normal ranges. Metabolic demands are best managed with tight control of the patient's hemodynamic profile, oxygen consumption, and environmental stimuli. The challenge of managing the critically ill postoperative patient is great, but the rewards of successful recovery are tremendous.
