Clinical Trial Summary

The aim of this trial is to investigate the efficacy of trigger point injections with 1% lidocaine in reducing myofascial back and neck pain in the Emergency Department compared to lidocaine patches 5%.


Description:

After being informed about the study and the potential risks and benefits, all patients will be randomized into either the trigger point injection group with 1% lidocaine, or the 5% lidocaine patch group. Pain scores will be recorded while in the emergency department, and we will have a 5 day follow-up phone call to assess efficacy. Patients who present to UCI Department of Emergency medicine will be screened and recruited prospectively, and information regarding this study will be available on clinicaltrials.gov as a method of recruitment.

Outcome

Type Measure Description Time frame Safety issue
Primary absolute change in Numerical Rating Scale (NRS) of pain Pain on a scale of 1-10. Minimum value is 1, maximum value is 10. Higher score means higher level of pain while lower score means lower level of pain. 0 minutes and 20-minutes post- treatment, and every 30-60 minutes thereafter until discharge or admission and we will give the patient a hand out so that they can record their pain scores for up to 5 days after their emergency department visit.
Secondary use of other medications for treatment of pain including medications administered How often and which medications did the patient require in emergency department and upon discharge to control their pain From initiation of the study up to 5 days post discharge
Secondary disposition times Number of minutes it takes to discharge or admit the patient from first contact From initiation of the study up to the point the patient is discharged from the emergency department
Secondary satisfaction/experience surveys regarding their treatment We will administer satisfaction/experience surveys to assess for any discomfort or relief from the intervention Immediately after the intervention is performed/administered
