Alcohol withdrawal syndrome.

In susceptible patients, alcohol withdrawal syndrome (AWS) is often precipitated by other medical or surgical disorders, and AWS can adversely affect the course of these underlying conditions. Although the mortality rate of AWS has decreased over the past few decades, significant risk for morbidity and death remain if management is complicated by a variety of conditions. This review of AWS focuses on the scope of the clinical problem, historical features, pathophysiology, clinical presentation, and approaches to therapy, with particular emphasis on severe AWS that requires management in the intensive care unit.
