What should be used if withdrawal is refractory?

• A. Increase benzodiazepine dose alone
• B. Synergistic treatment with barbiturates or propofol
• C. Use antidepressants
• D. Discontinue sedation

Answer: (B)

When a patient is on prolonged sedation, withdrawal symptoms can persist even after optimizing the benzodiazepine dose. If that withdrawal is not controlled with benzodiazepines alone, the best approach is to add other sedatives that work synergistically to provide deeper, more controllable anesthesia. Barbiturates or propofol fill that role, helping to blunt agitation, autonomic instability, and other withdrawal signs by enhancing CNS depression more robustly and predictably than increasing benzodiazepines alone. This strategy is used under careful monitoring in the ICU because these agents carry risks such as respiratory depression and hemodynamic effects, but they are effective when withdrawal is refractory to benzodiazepines. The other options don’t address the withdrawal physiology: simply raising benzodiazepines may lead to oversedation or respiratory compromise without fully suppressing withdrawal; antidepressants don’t treat acute withdrawal; stopping sedation altogether would exacerbate agitation and withdrawal symptoms and could destabilize the patient.
