Hemodynamic variables in the study population at baseline (B), after initial optimization (O), 20 minutes after spinal anesthesia in supine position (S), at entrance in the Recovery Room (RR), at the end of the study (F): p (O vs B) = significativity of the comparison between optimized and basal values; p (S vs O) = significativity of the comparison of values after spinal versus after optimization; p (RR vs O) = significativity of the comparison of values between Recovery Room admission and optimization; p (F vs B) = significativity of the comparison between the end of the study and baseline
