Brief Summary

Compare 0.05 μg/kg/min Norepinephrine and 0.25 μg/kg/min phenylephrine effect on fetus and parturient during Cesarean Section

Detailed Description

1. Compare 0.05 μg/kg/min Norepinephrine and 0.25 μg/kg/min phenylephrine and control group effect on parturient hemodynamic change (systolic blood pressure SBP, diastolic blood pressure DBP,mean arterial pressure MAP,heart rate HR) and on LIDICO-rapid monitoring ( stroke volume SV, systemic vascular resistance SVR, cardiac output CO) and peripheral vein (PV) blood gas during Cesarean Section.

2. Compare 0.05 μg/kg/min Norepinephrine and 0.25 μg/kg/min phenylephrine and control group effect on fetus by blood gas of the umbilical vein (UV), umbilical artery (UA),
