Data are expressed as mean ± SD or absolute number (percentage). ASA = American Society of anesthesiologists physical status; BMI = body mass index; HR = heart rate; MBP = mean blood pressure; IVC-CI = collapsibility index of IVC; dIVCmax = maximum diameter of IVC; dIVCmax = minimum diameter of IVC
