Summary

For verifying the phase lag entropy as the tool for measurement of level of consciousness, the investigators compared phase lag entropy to bispectral index. Using Target-Controlled Infusion pump, propofol was infused for sedation during the spinal anesthesia. The investigators measured Observer's Assessment of Alertness/Sedation Scale as the propofol concentration rises. At the same time, The investigators observed phase lag entropy score and bispectral index score.

Conditions

• Surgery Requiring Spinal Anesthesia

Interventions

Type	Name	Description
DEVICE	apply phase lag entropy sensor	apply phase lag entropy sensor as well as bispectral index sensor on forehead during the sedation using propofol
