A 52-year-old man with a known history of severe alcohol use disorder is brought to the emergency department by bystanders who found him unresponsive on the street. Initial vital signs show a heart rate of 115/min and blood pressure of 145/90 mm Hg. Point-of-care blood glucose is 42 mg/dL. As he slowly regains consciousness in the emergency department, he becomes visibly tremulous, anxious, and profusely diaphoretic. Arrange the following management steps in the most appropriate chronological order for this patient, proceeding from immediate acute stabilization to long-term outpatient care.
- 1Intravenous administration of thiamine
- 2Intravenous administration of 50% dextrose
- 3Symptom-triggered administration of intravenous lorazepam
- 4Implementation of motivational interviewing counseling
- 5Initiation of maintenance pharmacotherapy with naltrexone
Cevap
The correct sequence is: Thiamine administration, followed by dextrose administration, then symptom-triggered lorazepam, followed by motivational interviewing, and finally initiation of naltrexone.
The management of patients with severe alcohol use disorder must proceed in a logical, stepwise fashion prioritizing life-threatening acute complications before transitioning to chronic management. First, thiamine must be given prior to or alongside glucose to prevent Wernicke encephalopathy. Second, the acute hypoglycemia (42 mg/dL) must be reversed with dextrose. Third, as the patient awakens and exhibits autonomic hyperactivity, symptom-triggered benzodiazepines are required to manage acute withdrawal and prevent seizures. Fourth, once medically cleared, behavioral therapies like motivational interviewing are introduced. Finally, long-term relapse prevention medications like naltrexone are initiated prior to or upon discharge.

Anahtar Kavram
The comprehensive management of alcohol use disorder follows a strict chronological progression: preventing acute neurological complications (thiamine before glucose), stabilizing metabolic derangements, treating acute withdrawal (benzodiazepines), providing psychological intervention, and initiating long-term pharmacologic relapse prevention.
