Conditions

Post-induction hypotension

Interventions

High SBRI group (Group H):If the left SBRI was =0.89, then they were included in group H. Rehydration therapy with 8 ml/kg was completed within 30 min before induction.
Low SBRI group (Group L):If the left SBRI was <0.89, they were included in group L. Continuous intravenous fluids were administered at a rate of 5 ml/kg/h.
