Design outcomes

Primary

Measure	Time frame
Time to reach the maximum level of sensory block. Timepoint: Immediately after spinal anesthesia until the onset of sensory block. Method of measurement: Use the watch to measure time and the needle(pinprick) to determine the sensory block.;Sensory block quality. Timepoint: Before surgery. Method of measurement: Visual Analog Scale(VAS).;Motor block quality. Timepoint: Before surgery. Method of measurement: Bromage score.	—
