Common complications in the critically ill patient

Critically ill patients in intensive care units are subject to many complications associated with therapy. Many of these complications are health care-associated infections and are related to indwelling devices, including ventilator-associated pneumonia, central line-associated bloodstream infection, catheter-associated urinary tract infection; surgical site infection, venous thromboembolism, deep venous thrombosis, and pulmonary embolus are other common complications. All efforts should be undertaken to prevent these complications in surgical critical care, and national efforts are under way for each of these complications. In this article, epidemiology, risk factors, diagnosis, treatment, and prevention of these complications in critically ill patients are discussed.
