2018
Background:Alcohol withdrawal syndrome (AWS) is a common reason for admission to a medical intensive care unit (MICU) and requires significant hospital resource utilization. Benzodiazepines are first-line therapy for AWS in many intensive care units. We propose the use of symptom-triggered phenobarbital for the treatment of AWS as a safe alternative to benzodiazepines.Methods:This was a retrospective observational study of a 4-year period, 2011 to 2015, of all patients with AWS admitted to the MICU of 1 tertiary care hospital and treated with phenobarbital. A symptom-triggered protocol was used. Resolution of AWS was assessed with the Richmond Agitation Sedation Scale to goal score of 0 to −1. The Charlson Comorbidity Index was used as an index of patient illness severity. Complications associated with phenobarbital use and/or the AWS admission were analyzed.Results:Data of 86 AWS patient encounters were analyzed. The mean Clinical Institute Withdrawal Assessment for Alcohol–Revised score of patients admi...
