Phase 2

Conditions
Pain, Acute
Interventions
Registration Number
NCT04061330
Lead Sponsor
The University of Texas Health Science Center, Houston
Brief Summary

The purpose of this study is to establish the feasibility of initiating a ketamine pain control protocol in the emergency department for the treatment of acute pain in patients with long bone fractures and to compare the efficacy of the ketamine pain protocol to bolus morphine for pain control in the first 6 hours of patient stay in the emergency department.

Primary Outcome Measures
NameTimeMethod
Clinical pain as assessed by the Numerical pain rating score (NPRS)6 hours after initial administration of drug

The NPRS total score ranges form 0-10,0 being no pain and 10 being worst possible pain.

Secondary Outcome Measures
NameTimeMethod
Score on Richmond Agitation-Sedation Scale (RASS)6 hours after initial administration of drug

The RASS is a 10-point scale ranging from +4 to -5, with four levels of anxiety or agitation (+4 to +1), one level denoting a calm and alert state (0), and 5 levels of sedation (-1 to -5). +4 represents a very combative, violent patient, and on the other extreme -5 represents a patient who is unarousable, with no response to voice or physical stimulation.

Physician satisfaction with analgesiaend of treatment (about 6 hours after initial administration of drug)

Physician satisfaction will be measured on a 5 point scale, with 1 being very unsatisfied and 5 being very satisfied.

Number of hypotension episodes6 hours after initial administration of drug

Hypotension occurs when systolic blood pressure (SBP) is less than 100mmHg

Number of participants with need for rescue benzodiazepine therapy in ketamine group for emergence phenomenon and dysphoriafrom time of initial administration of drug to end of treatment (about 6 hours after initial administration of drug)
Number of participants with Adverse reactionsfrom time of initial administration of drug to end of treatment (about 6 hours after initial administration of drug)
Number of participants with need for rescue opioid therapyfrom time of initial administration of drug to end of treatment (about 6 hours after initial administration of drug)
Patient satisfaction with analgesiaend of treatment (about 6 hours after initial administration of drug)

Patient satisfaction will be measured on a 5 point scale, with 1 being very unsatisfied and 5 being very satisfied.

Number of hypoxic episodes as measured with a continuous pulse oximeter6 hours after initial administration of drug

Hypoxic episodes occur when peripheral capillary oxygen saturation (SPO2) is less than 90 percent as measured by a continuous pulse oximeter.

Nursing satisfaction with analgesiaend of treatment (about 6 hours after initial administration of drug)

Nursing satisfaction will be measured on a 5 point scale, with 1 being very unsatisfied and 5 being very satisfied.
