Study type | Interventional |
This study is designed to evaluate the addition of ketamine to dexmedetomidine as adjunctive therapies of severe alcohol withdrawal in medical ICU patients. Specifically, this study will assess whether the combination of ketamine and dexmedetomidine reduces the doses of conventional agents used for alcohol withdrawal while maintaining patient comfort and safety and will explore if the combination alters the expression of catecholamines in the serum over time.

Eligibility |
Inclusion Criteria: 1. Severe alcohol withdrawal defined by a CIWA score = 15 and the need for at least 16 mg of lorazepam equivalents over a four-hour period. All benzodiazepine and barbiturate doses, whether oral or intravenous, will contribute to the cumulative amount using the following conversion: 1 mg lorazepam = 2 mg midazolam = 7.5 mg clorazepate = 15 mg phenobarbital. 2. Patients receiving standard therapy for severe alcohol withdrawal according to the UCH-specific, symptom-triggered alcohol withdrawal protocol in the ICU (or admission to the ICU is anticipated). Lorazepam is the preferred benzodiazepine agent for patients requiring ICU admission due to alcohol withdrawal. 3. Informed consent within 36 hours of qualifying for the study. Exclusion Criteria: 1. Patients < 18 years of age or > 85 years of age. 2. Patients receiving benzodiazepine therapy for purposes other than alcohol withdrawal (e.g. sedation, seizure control other than alcohol withdrawal). 3. Patients with alcohol withdrawal not requiring ICU admission. 4. Patients receiving epidural administration of medication(s). 5. Comatose patients by metabolic or neurologic affectation. 6. Patients with active myocardial ischemia or second- or third-degree heart block. 7. Patients with Child-Pugh score of C. 8. Moribund state with planned withdrawal of life support. 9. Patient pending transfer to another facility. 10. Patients with known or suspected severe adverse reactions to dexmedetomidine (or clonidine) or ketamine. 11. Pregnant females or females suspected of being pregnant. 12. Prisoners or active parolees. 13. Previous study participation. 14. Patients already receiving ketamine for alcohol withdrawal. Patients receiving dexmedetomidine will be excluded if the infusion exceeds 1 µg/kg per hour for more than two hours or any rate for a cumulative duration of 12 hours. |

Primary | Cumulative Lorazepam Dose Over the First 12 Hours of Alcohol Withdrawal | As part of routine care, the bedside nurse will record the administration of all sedative agents. The hourly, daily and cumulative doses of agents will be determined by the sum of as needed doses, scheduled intermittent doses, and hourly infusion rates. All conventional therapies will be guided by the institution-specific, symptom-triggered alcohol withdrawal protocol to maintain CIWA scores = 7. Intravenous lorazepam is the preferred benzodiazepine for management of alcohol withdrawal in the medical ICU. Phenobarbital and propofol are infrequently used and they are not included in the protocol. All benzodiazepine and barbiturate doses, whether oral or intravenous, will be converted to lorazepam equivalents using the following conversion: 1 mg lorazepam = 2 mg midazolam = 7.5 mg clorazepate = 15 mg phenobarbital. | 12 hours | |
Primary | Cumulative Lorazepam Dose Over the First 24 Hours of Alcohol Withdrawal | As part of routine care, the bedside nurse will record the administration of all sedative agents. The hourly, daily and cumulative doses of agents will be determined by the sum of as needed doses, scheduled intermittent doses, and hourly infusion rates. All conventional therapies will be guided by the institution-specific, symptom-triggered alcohol withdrawal protocol to maintain CIWA scores = 7.

Primary | Cumulative Lorazepam Dose Over the 72 Hours of Alcohol Withdrawal | As part of routine care, the bedside nurse will record the administration of all sedative agents. The hourly, daily and cumulative doses of agents will be determined by the sum of as needed doses, scheduled intermittent doses, and hourly infusion rates. All conventional therapies will be guided by the institution-specific, symptom-triggered alcohol withdrawal protocol to maintain CIWA scores = 7. Intravenous lorazepam is the preferred benzodiazepine for management of alcohol withdrawal in the medical ICU. Phenobarbital and propofol are infrequently used and they are not included in the protocol. All benzodiazepine and barbiturate doses, whether oral or intravenous, will be converted to lorazepam equivalents using the following conversion: 1 mg lorazepam = 2 mg midazolam = 7.5 mg clorazepate = 15 mg phenobarbital. | 72 hours | |
Secondary | Change in 12-Hour Lorazepam Requirement Pre- and Post-Treatment | As part of routine care, the bedside nurse will record the administration of all sedative agents. The hourly, daily and cumulative doses of agents will be determined by the sum of as needed doses, scheduled intermittent doses, and hourly infusion rates. All conventional therapies will be guided by the institution-specific, symptom-triggered alcohol withdrawal protocol to maintain CIWA scores = 7. Intravenous lorazepam is the preferred benzodiazepine for management of alcohol withdrawal in the medical ICU.

Secondary | Change in 24-Hour Lorazepam Requirement Pre- and Post-Treatment | As part of routine care, the bedside nurse will record the administration of all sedative agents. The hourly, daily and cumulative doses of agents will be determined by the sum of as needed doses, scheduled intermittent doses, and hourly infusion rates. All conventional therapies will be guided by the institution-specific, symptom-triggered alcohol withdrawal protocol to maintain CIWA scores = 7.

Secondary | The Degree of Alcohol Withdrawal Assessed by Clinical Institute Withdrawal Assessment (CIWA) Scores | CIWA scores will be assessed hourly by the bedside nurse. The proportion of CIWA scores = 15 (severe withdrawal symptoms), 8 - 14 (moderate withdrawal symptoms), and = 7 (minimal withdrawal symptoms) will be determined. | 72 hours | |
Secondary | The Occurrence of Adverse Events: hypotension, hypertension, bradycardia, tachycardia | Blood pressure and heart rate will be assessed hourly by the bedside nurse. Hypotension will be defined as a systolic blood pressure = 90 mmHg or a decrease of systolic blood pressure of 40 mmHg, hypertension will be defined as a systolic blood pressure = 180 mmHg or an increase of systolic blood pressure of 40 mmHg, bradycardia will be defined as a heart rate = 55 beats/minute or a decrease of 20 beats/minutes, and tachycardia will be defined as a heart rate = 120 beats/minute or an increase of 20 beats/minutes. Highest and lowest daily measurements of each will also be collected. | 72 hours | |
Secondary | Plasma Epinephrine Concentrations Across Groups Over Time | Plasma epinephrine concentrations will be assessed prior to study drug and at times 24, 48, 72 and 96 hours after initiating study drug | 96 hours |
