CLONIDINE IN THE TREATMENT OF ALCOHOL WITHDRAWAL IN THE INTENSIVE CARE UNIT

Abstract Background The Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) is commonly used in hospitals to titrate medications for alcohol withdrawal syndrome (AWS), but may be difficult to apply to intensive care unit (ICU) patients who are too sick or otherwise unable to communicate. Objectives To evaluate the frequency of CIWA-Ar monitoring among ICU patients with AWS and variation in CIWA-Ar monitoring across patient demographic and clinical characteristics. Methods The study included all adults admitted to an ICU in 2017 after treatment for AWS in the Emergency Department of an academic hospital that standardly uses the CIWA-Ar to assess AWS severity and response to treatment. Demographic and clinical data, including Richmond Agitation-Sedation Scale (RASS) assessments (an alternative measure of agitation/sedation), were obtained via chart review. Associations between patient characteristics and CIWA-Ar monitoring were tested using logistic regression. Results After treatment for AWS, only 56% (n = 54/97) of ICU patients were evaluated using the CIWA-Ar; 94% of patients had a documented RASS assessment (n = 91/97). Patients were significantly less likely to receive CIWA-Ar monitoring if they were intubated or identified as Black. Conclusions CIWA-Ar monitoring was used inconsistently in ICU patients with AWS and completed less often in those who were intubated or identified as Black. These hypothesis-generating findings raise questions about the utility of the CIWA-Ar in ICU settings. Future studies should assess alternative measures for titrating AWS medications in the ICU that do not require verbal responses from patients and further explore the association of race with AWS monitoring.

Objective: To report a case of alcohol withdrawal and delirium tremens successfully treated with adjunctive dexmedetomidine. Case Summary: A 30–year-old man with a history of alcohol abuse was admitted to the general medical unit because of altered mental status and agitation. He was initially treated for alcohol withdrawal with benzodiazepines; his condition then deteriorated and he was transferred to the intensive care unit. Because of the patient's poor response to benzodiazepines (oxazepam and lorazepam, with midazolam the last one used), intravenous dexmedetomidine was started at an initial dose of 0.2 µg/kg/h and titrated to 0.7 µg/kg/h to the patient's comfort. Midazolam was subsequently tapered to discontinuation due to excessive sedation. In the intensive care unit, the patient's symptoms remained controlled with use of dexmedetomidine alone. He remained in the intensive care unit for 40 hours; dexmedetomidine was then tapered to discontinuation and the patient was transferred back to the general medical unit on oral oxazepam and thiamine, which had been started in the emergency department. He was discharged after 5 days. Discussion: A review of the PubMed database (1989-2007} failed to identify any other instances of dexmedetomidine having been used as the principal agent to treat alcohol withdrawal. The use of sedative to treat delirium tremens Is well documented, with benzodiazepines being the agents of choice. The clinical utility of benzodiazepines is limited by their stimulation of the γ-aminobutyric acid receptors, an effect not shared by dexmedetomidine, a central α2-receptor agonist that induces a state of cooperative sedation and does not suppress respiratory drive. Conclusions: In patients with delirium tremens, dexmedetomidine should be considered as an option for primary treatment. This case illustrates the need for further studies to investigate other potential uses for dexmedetomidine.
