If I enumerate the problems associated with alcohol and anaesthesia, you may never consume alcohol. Leading cause of death in chronic alcoholic is cardiac dysfunction . It may result in congestive cardiomyopathy with pulmonary hypertension, dysrhythmias and right sided heart failure. They're often susceptible to pulmonary infections often by staphylococcus or gram negative organisms. Needless to say, Wernicke encephalopathy and Korsakoff psychosis are often associated with chronic alcoholics.
Cross tolerance develops to Intravenous anesthetic agents. Muscle relaxant would have unusually long action on them. And yes, alcohol withdrawal syndrome may appear under anaesthesia as diaphoresis, tachycardia and hypertension.
