Design outcomes

Primary

Measure	Time frame
Correlation between chnage in regional cerebral blood volume and oxygenation measured by near-infrared spectroscopy and change in cardiac output and systemic vascular resistance measured by arterial pressure based cardiac output monitaring system during 15 min after induction of spinal anesthesia	—

Secondary

Measure	Time frame
1. Characteristics of indexes of regional cerebral circulation and hemodynamic when appearence of adverse symptoms. 2. Change in indexes of regional cerebral circulation and hemodynamic after administration of vasopressor agents.	—
