Brief Summary:
This study will prospectively compare the mean Numerical Rating Scale (NRS) pain score reduction amongst three recommended dosing strategies of intravenous ketamine (0.1 mg/kg, 0.2 mg/kg, and 0.3mg/kg) for acute pain in the emergency department (ED).This study will also examine the frequency of adverse events secondary to ketamine including fatigue, dizziness, nausea, headache, feeling of unreality, changes in hearing or vision, mood changes, generalized discomfort, and hallucinations, changes in vital signs. Subgroups for exploratory analysis based on the need for rescue analgesia within two hours of ketamine administration, adequate pain relief, previous opioid tolerance, and age (adults < 65 years old and > 65 years old).

| Acute Pain | Drug: Ketamine Injectable Product | Phase 4 |
A literature review was performed that searched for randomized clinical trials involving ketamine IV boluses for acute pain in the Emergency Department. Studies involving continuous infusions or intranasal routes of ketamine administration were not included. Thirteen randomized clinical trials were identified meeting this criteria. None of these trials directly compared ketamine doses within the 0.1-0.3 mg/kg range for pain score reduction and adverse events. Many of these trials concluded with the recommendation that further studies were needed to evaluate the optimal dosing of ketamine for acute pain and determine which populations are most ideal for its use. This study will be the first to evaluate ketamine for acute pain in the emergency department at standard of care doses (0.1 mg/kg, 0.2 mg/kg, and 0.3 mg/kg IV) to determine which dose correlates with the most efficacy and safety.
This study will include the following procedures:
- Patient consent, screening, and enrollment will be performed by the treating resident or attending who will remain blinded
- Patient will be assigned a subject number
- Treating resident or attending will notify the ED pharmacist that a patient has been enrolled in the trial
- ED pharmacist will notify the IV room and place the study drug order
- Either the ED pharmacist or a pharmacy supervisor will randomize the subject based on the predetermined randomization list
- Study drug will be prepared as 0.1 mg/kg, 0.2 mg/kg, or 0.3 mg/kg IV dose in a 100 mL solution of dextrose 5% or sodium chloride 0.9%
- ED pharmacist will promptly deliver the study drug to the ED
- Baseline vital signs will be assessed prior to starting the study drug infusion
- Study drug will be administered via IV infusion over 20 minutes
- Treating resident or attending will reassess the patient at 15 minutes from the end of infusion, at 30 minutes from the end of infusion, and then every 30 minutes for up to 120 minutes or until discharge, whichever is sooner

| Arm | Intervention/treatment |
|---|---|
|
Active Comparator: Arm 1: 0.1 mg/kg ketamine
0.1 mg/kg in a 100 mL solution of dextrose 5% or sodium chloride 0.9% will be give after patient consent and enrollment in the study, vitals are followed (heart rate, systolic blood pressure and respiratory rate) for 2 hours following completion of ketamine infusion. Evaluated for side effects for 2 hours following completion of ketamine infusion.

Active Comparator: Arm 1: 0.2 mg/kg ketamine
0.2 mg/kg in a 100 mL solution of dextrose 5% or sodium chloride 0.9% will be give after patient consent and enrollment in the study, vitals are followed (heart rate, systolic blood pressure and respiratory rate) for 2 hours following completion of ketamine infusion. Evaluated for side effects for 2 hours following completion of ketamine infusion.

Active Comparator: Arm 1: 0.3 mg/kg ketamine
0.3 mg/kg in a 100 mL solution of dextrose 5% or sodium chloride 0.9% will be give after patient consent and enrollment in the study, vitals are followed (heart rate, systolic blood pressure and respiratory rate) for 2 hours following completion of ketamine infusion. Evaluated for side effects for 2 hours following completion of ketamine infusion.

Primary Outcome Measures :
- Pain score [ Time Frame: 2 hours post infusion completion ]Pain score using Numerical Rating Scale (NRS) post ketamine infusion. The Numerical Rating Scale (NRS) ranges from 0-to-10 with 0 being no pain and lower numbers representing less pain, so in this case lower numbers will represent better outcomes.
Secondary Outcome Measures :
- Adverse Events [ Time Frame: 2 hours post infusion completion ]Frequency of adverse events secondary to ketamine including fatigue, dizziness, nausea, headache, feeling of unreality, changes in hearing or vision, mood changes, generalized discomfort, and hallucinations, changes in vital signs.
