Single-dose Ketamine for the Reduction of Pain and Depression in the Emergency Department

7. februar 2020 opdateret af: Maria Pacella

Single-dose Ketamine to Reduce Pain Severity, Depressive Symptoms and the Need for Opiates Both During and After Emergency Department Care

In this proposal, the investigators will determine if a single dose of intravenous (IV) ketamine (in combination with midazolam) reduces pain severity, depressive symptoms and need for opiate analgesics both in the ED and in the acute recovery period after ED discharge. The investigators will compare the ketamine arm to an active placebo-controlled arm (with midazolam).

Detaljeret beskrivelse

The investigators will enroll 120 medically stable adult patients who present to two Emergency Departments with a chief complaint of acute pain.

The investigators will randomly assign subjects using a blocked randomization schedule to either: 1) a single dose of IV ketamine (0.3 mg.kg) + midazolam, or 2) placebo + midazolam. ED providers and patients will be blind to treatment allocation.

All participants will complete measures of pain and mood scores every 30 minutes, and the investigators will record any analgesics administered in the ED until discharge. At 7-days and 14-days post- discharge, the investigators will measure summary reports of pain severity, mood, and analgesic medication used.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Experimental Arm
Participants will be assigned to receive a single dose of IV ketamine (0.3 mg.kg) + midazolam
Medicin: Ketamine
Ketamine is a medication approved by the US Food and Drug Administration (FDA) for anesthesia, sedation, and post-surgical pain treatment. It is not approved for emergency patients complaining of pain but is often used "off-label." Ketamine may be useful for acute pain management and in treatment of depressed mood. The purpose of this study is to determine whether a single low dose of ketamine can relieve pain and reduce negative mood for 2 weeks after emergency department (ED) treatment.
Medicin: Midazolam
In this study, all patients will also receive midazolam. Midazolam is a sedative that typically makes people feel relaxed and is intended to increase comfort with ketamine and reduce anxiety.
Aktiv komparator: Active Placebo Arm
Participants will be assigned to receive a single dose of IV placebo + midazolam
Medicin: Midazolam
In this study, all patients will also receive midazolam. Midazolam is a sedative that typically makes people feel relaxed and is intended to increase comfort with ketamine and reduce anxiety.
Medicin: Placebo
In this study, patients in the active comparator group will receive midazolam first, then placebo. A placebo is an inactive solution that looks like the study drug, but contains no active ingredients.
