Purpose
This study aims to compare the alternative current and the direct current signal changes of photoplethysmography between both feet during one side lumbar sympathetic block.
The hypothesis is that signal changes occur earlier than other indices to decide whether it is successful following lumbar sympathetic block on only one-side.

Primary Outcome Measures:
- Index of sympathetic block [ Time Frame: 1 minute at intervals from baseline through end of procedure ]
change of slope of signals of the alternative current and the direct current from foot
The baseline is defined as the point of surgical drap.
The end of procedure is decided when the temperature of foot is increased more than 2 degrees from baseline within 20 minutes after local anesthetics injection
Secondary Outcome Measures:
- skin temperature changes [ Time Frame: 1 minute at intervals during procedure ]foot temperature change from baseline
- electrocardiogram [ Time Frame: 1 minute at intervals from baseline through end of procedure ]heart rate variability measurement
