What You Need to Know Before You Apply

What is the purpose of this trial?

This study evaluates if the early utilization of ketamine infusion therapy among acutely injured adult trauma hospital inpatients with an ISS \>15 will decrease the amount of opioid pain medication used as compared with placebo group. Ketamine infusion therapy initiated within 12 hours of hospital arrival will lead to decreased total opiate consumption (standardized to oral morphine equivalent units) in the first 24 and 48 hours compared to controls.

Are You a Good Fit for This Trial?

This trial is for adults aged 18-64 who've been hospitalized with severe trauma (ISS >15) and can start treatment within 24 hours of arrival. It's not for those over 64, under 18, with a history of ketamine issues, chronic opioid use, substance abuse, certain heart or brain conditions, glaucoma, pregnancy, severe hypertension, prisoners or if they're on MAOIs.

What Are the Treatments Tested in This Trial?

Interventions

• Ketamine
• Placebo

Trial Overview The study tests whether early ketamine infusion reduces the need for opioid painkillers in the first 24 to 48 hours after hospital admission compared to a placebo in adult trauma patients with significant injuries.

How Is the Trial Designed?

Group I: Ketamine arm Experimental Treatment 1 Intervention

Early ketamine infusion therapy at a rate of 3 mcg/kg/min. All ketamine infusions will be calculated based on ideal body weight (IBW), unless actual body weight is less than ideal. Ketamine infusion therapy will be continued for 48 hours. At 2-4 hours post-infusion the patient's pain will be reassessed. If the NPS is more than 5 the infusion will be increased to 5mcg/kg/min. Following each change in the infusion rate the patient's pain will be reassessed at 2-4 hours and adjustments made accordingly. Maximum infusion rate will be set at 9mcg/kg/min. Conversely, The RAAPS team should be notified if neurologic symptoms (hallucinations, delusions, disturbing dreams, vertigo) are developing and, at the discretion of the RAAPS service, a single dose of lorazepam or midazolam may be utilized. The infusion can be decreased from in 2 mcg/kg/min increments if there are symptoms believed to be related to the infusion that do not respond to benzodiazepines.

Group II: Placebo arm Placebo Group 1 Intervention

The 65 patients randomized to the control arm will receive placebo saline solution at a rate equivalent.
