Table 2: Absoluete heart rate (HR), stroke volume (SV), cardiac output (CO), mean arterial pressure (MAP), systemic vascular resistance (SVR), bispectral index (BIS) at pre-induction and 30, 60, 90, 120, 150 and 180 seconds (s) after induction. Data are mean (SD). **Data is median (IQR). * indicates a significant difference (p<0.001) in parameter compared to pre-induction.
