Summary

Regional tissue oxygenation saturation has been shown to increase in innervated regions after sympathetic block. The aim of this prospective observational study was to evaluate the changes of regional tissue oxygenation saturation by near-infrared spectroscopy after successful femoral nerve block with ropivacaine and determine whether the changes of regional tissue oxygenation saturation can be affected by the concentration of ropivacaine.

Detailed description

Successful peripheral nerve blocks induce sympathetic blockade, which increases local blood flow by vasodilation. The relationship between successful femoral nerve block and the variation of regional tissue oxygenation saturation was unclear.
