Study Arms:
- Control group (Type: PLACEBO_COMPARATOR): Simultaneous with spinal anesthesia, 500 mL 6% Hydroxyethyl starch (130/0.4) coload was given and a maintenance dose of normal saline by IV infusion.
- 0.025 μg/kg/min group (Type: EXPERIMENTAL): Simultaneous with spinal anesthesia, 500 mL 6% Hydroxyethyl starch (130/0.4) coload was given and a maintenance dose of norepinephrine (0.025 μg/kg/min) by IV infusion.
- 0.05 μg/kg/min group (Type: EXPERIMENTAL): Simultaneous with spinal anesthesia, 500 mL 6% Hydroxyethyl starch (130/0.4) coload was given and a maintenance dose of norepinephrine (0.05 μg/kg/min) by IV infusion.
- 0.075 μg/kg/min group (Type: EXPERIMENTAL): Simultaneous with spinal anesthesia, 500 mL 6% Hydroxyethyl starch (130/0.4) coload was given and a maintenance dose of norepinephrine (0.075 μg/kg/min) by IV infusion.
- 0.1μg/kg/min group (Type: EXPERIMENTAL): Simultaneous with spinal anesthesia, 500 mL 6% Hydroxyethyl starch (130/0.4) coload was given and a maintenance dose of norepinephrine (0.1μg/kg/min) by IV infusion.
