Statins are effective lipid-lowering agents used extensively in medical practice. This review summarizes the evidence for statin treatment of cardiovascular patients in the intensive care unit and briefly discusses the role of statins in prevention and treatment of sepsis as a potential future application of statins in critical care. ⋯ Statin therapy should be continued in intensive-care patients in whom statin therapy is warranted due to underlying cardiovascular disease or significant risk thereof. In acute coronary syndromes, statin therapy should be initiated within 24-96 h regardless of pretreatment cholesterol levels. Patients undergoing vascular surgery should receive peri-operative statin therapy. Placebo-controlled clinical trials are required to consolidate the experimental and observational evidence for prevention and treatment of sepsis.

The inflammatory or stress response to injury has evolved to ensure survival. This review will examine this response in otherwise healthy patients. Additionally, the impact of several common comorbid conditions on the inflammatory response will be considered. What will become evident is that the stress response may be exaggerated in some conditions and suppressed in others. Rapid identification of both an abnormal response and its cause will allow clinicians to maximize a patient's healing potential. ⋯ An understanding of the stress response will aid the clinician in preparing for expected responses, recognizing and perhaps correcting deviations from the norm and accounting for potential complications that arise in the face of preexisting disease. Deviations from the normal time course may represent the effects of preexisting medical illness, treatment or postoperative/injury complications.
