Alcohol withdrawal requiring massive prolonged benzodiazepine infusion

Area of Science:

• Intensive Care Medicine
• Pharmacology
• Addiction Medicine

Background:

• Alcohol withdrawal syndrome (AWS) can be severe and prolonged, especially in patients with chronic alcohol dependence.
• Management of AWS typically involves benzodiazepines, often on a symptom-triggered basis.
• Post-surgical patients with alcohol dependence present unique challenges in managing AWS.

Observation:

• A 58-year-old male with alcohol dependence developed severe agitation and mental status changes post-cystoprostatectomy.
• Symptom-triggered benzodiazepine therapy was ineffective in controlling the patient's AWS.
• The patient required massive, high-dose, fixed-interval benzodiazepine administration for 5 weeks in the medical intensive care unit.

Findings:

• Prolonged and severe alcohol withdrawal can necessitate extended, high-dose benzodiazepine regimens.
• Fixed-interval dosing may be superior to symptom-triggered protocols in complex AWS cases.
• Massive benzodiazepine doses were required but did not result in observable toxicity in this patient.

Implications:

• This case underscores the need for individualized treatment strategies in managing severe AWS.
• Interdisciplinary team collaboration and adherence to slow-weaning protocols are vital for patient recovery.
• Further research into optimal dosing strategies for prolonged AWS is warranted.
