The purpose of this study is to determine the effect of a local anesthetic nerve block on markers of inflammation and pain after a sunburn. This is important because it may provide information regarding the way that nerve blocks help with the treatment of pain and in particular provide preemptive analgesia.

Condition Intervention
Procedure: femoral nerve block

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Crossover Assignment
Masking: Double-Blind

Further study details as provided by Stanford University:

Primary Outcome Measures:
  • Measurement of the effect of a preemptive peripheral nerve block on the hyperalgesic response to an artificially induced sunburn.

Secondary Outcome Measures:
  • Measurement of the effect of a preemptive peripheral nerve block on the release of pro-inflammatory cytokines.
