Brief summary
The Ketamine for Acute Pain in Burns study is a randomized, double-blind, parallel group trial (RCT) with active control (usual care) contrasting the efficacy and safety of Ketamine Plus Opiate-based usual care (O+K) with the safety and efficacy of the Current Standard of Care. THe current standard of care is an opiate medication alone, Fentanyl (Usual Care-Opiate (UC-O), dose/timing as per Burn Center protocol).
Detailed description
Department of Defense (DoD) and the U.S. Army Medical Research and Materiel Command (USAMRMC) are funding this RCT for the following reasons: Primary Aims: 1. To evaluate the safety and efficacy of fentanyl (usual care) + placebo versus fentanyl + ketamine (low-dose, sub-anesthetic, slow-infusion) during twice daily burn wound care across a 7-day study period and 30 day outcome period. 2. To evaluate the opiate sparing effect of fentanyl (usual care) + placebo versus fentanyl + ketamine (low-dose, sub-anesthetic, slow-infusion) during the 7-day study period and 30 day outcome period. and Secondary Aims: 1. To determine the short and long term effect of the Ketamine Augmentation Condition versus the Usual Care Condition on symptoms and syndromes of posttraumatic stress disorder and of depression, 2. To evaluate several established and hypothesized moderators of the relationship between the Ketamine Augmentation Condition versus the Usual Care Condition on: 1) pain severity reported during wound care, 2) opiate use during wound care, 3) posttraumatic stress and 4) depression.

Study design
Masking description
Pharmacy receives order from provider and then prepares the study drug in an unmarked, nondescript delivery system (bag) and the study drug information is entered from the bag into the pump so that delivery that is timed and volume controlled per study protocol. This is hung next to patient, connected and started. Masked personnel include provider (order study drug protocol), nurse (wound care), data assessor (Research Assistant), and consenting participant (patient with acute burn).
Intervention model description
Randomized, placebo-controlled, repeated exposure (twice daily, 7 days), safety and efficacy trial of Usual Care (fentanyl PLUS saline / placebo) versus Usual Care plus Study Drug Augmentation (fentanyl PLUS ketamine) in reducing acute pain severity assessed before, during and after wound care for acute burn injury in the Burn Center of an Academic Medical Center.

| Fentanyl Plus Ketamine Study drug group
1. Ketamine Loading Dose (Low Dose, Slow Infusion) =
• 0.3 mg/kg; Initiated approximately 10 minutes before wound care start, pump set to deliver slowly over approximately 5 minutes, … Then,
2. Fentanyl Loading Dose (UC, injection) =
• 1 mcg / kg. This is given to participants in both Group 1 and Group 2 initiated \< 1 minute prior to wound care.
3. Ketamine (Study Drug, Infusion) = • 2.5 mcg/kg/min, Pump initiates infusion immediately after the fentanyl Loading Dose and continued for session duration. The nurse determines session end, then turns off infusion.
Fentanyl PRN dose\* = 1 mcg / kg. Provided when participant requires additional pain medication.
