Patients with chronic alcohol dependence are at risk for developing alcohol withdrawal syndrome when alcohol intake is suddenly stopped, which can begin 6-24 hours after the last drink and may include tremors, anxiety, tachycardia, hypertension, and potentially progress to seizures or delirium tremens. The preoperative plan should include consultation with appropriate specialists to evaluate withdrawal risk and potentially implement a prophylactic protocol to prevent withdrawal during the perioperative period. This approach helps ensure patient safety and reduces the risk of serious complications during recovery.
