Arms Assigned Interventions
Active Comparator: Levobupivacaine
Lumbar puncture with Levobupivacaine for spinal anesthesia
 Drug: bupivacaine, levobupivacaine
intrathecal injection 15~20mg(for Levobupivacaine) or 10~15mg(for Bupivacaine) once
Active Comparator: Bupivacaine
Lumbar puncture with Bupivacaine for spinal anesthesia
 Drug: bupivacaine, levobupivacaine
intrathecal injection 15~20mg(for Levobupivacaine) or 10~15mg(for Bupivacaine) once

Detailed Description:

Obtain the heart rate variability (in means and standard deviation, including the high frequency, low frequency and its ratio) data of before and after spinal anesthesia with ECG (and Heart Rate Variability Analyzer) in 2 groups. Meanwhile, record the blood pressure on each subject.
