Substance Use Disorder: Planning Care for Alcohol Withdrawal
● Pathophysiology: Chronic alcohol use leads to CNS adaptation. Abrupt cessation results

○ Peak (24–48 hr): Seizures.
○ Late (48–72 hr): Delirium tremens — hallucinations, hypertension, tachycardia,
fever.
● Medications:
○ Benzodiazepines (Lorazepam, Diazepam): Prevent seizures.
○ Thiamine (Vitamin B1): Prevent Wernicke’s encephalopathy.
○ Multivitamins and Folic Acid.
● Nursing Priorities:
○ Seizure precautions.
○ Quiet, calm environment.
○ Monitor vital signs, mental status.
○ Fluid replacement.
● Complications:
○ Seizures.
○ Delirium tremens.
, ○ Cardiac dysrhythmias.
