Figure 2

Individual response to prophylactic ephedrine at corresponding dosage in group C (A) and group G (B). The ED50 of intravenous ephedrine dosage calculated by up-down analysis was 0.14 mg/kg (95% CI, 0.13–0.16 mg/kg) in group C, and 0.08 mg/kg (95% CI, 0.06–0.11 mg/kg) in group G. Solid lines represent the ED50 values, and dashed lines represent the 95% CI. ED50 effective dose in 50% of subjects, CI confidence interval.
