Condition or disease
Other: Glucose 5%Other: NaCl 0.9%
The operator is blinded to the medium fluid to expand the perineural femoral and sciatic nerves before threading in the stimulating catheter. He records all the electric data of electrolocation of nerve, which will be compared to determine whether or not a difference in intensity is found between normal saline or dextrose 5% in water.
