简要总结
This study evaluates the addition of a lidocaine patch to ibuprofen in the treatment of acute musculoskeletal pains. Half of the participants will get only ibuprofen for their pain, while other half will receive lidocaine patch plus the ibuprofen. After addition of the pain medications, the participants will be followed for their pain scores and return visits.
详细描述
Ibuprofen and other nonsteroidal antiinflammatory pain medications have been traditionally used for relief of mild to moderate acute musculoskeletal pains. However, if this medication did not work, a different modality for pain control would be added to the original regimen. In recent times, lidocaine patch has been introduced as a separate modality for pain control. This medication is thought to help by selectively inhibiting voltage-gated sodium channels in nociceptors involved in pain response. Given the separate modality, it would be prudent to see whether the addition of lidocaine patch to the ibuprofen would help relieve the pain more so than the antiinflammatory-only regimen.

结局指标
主要结局
Change in Numerical Pain Rating Scale
时间窗: 60 minutes
Change in self-reported pain intensity level. Baseline will be prior to intervention, and change will be assessed 60 minutes after intervention. Each item is scored 0-10 (0=No pain, 10= Worst pain possible). Higher number is worse outcome while lower number is better outcome.
次要结局
- Number of Participants With a Return Visit for Same Chief Complaint(1 week)
