Data are expressed as median with interquartile range (25th to 75th percentiles). * P < 0.05, ** P < 0.001, *** P < 0.0001 post VE vs pre VE. † P < 0.001, †† P = 0.0001 responders vs nonresponders. ΔPPrad :radial artery pulse pressure variation; ΔSVVigileo :stroke volume variation measured with FloTrac/Vigileo® monitoring system; ΔVpeakbrach :brachial artery peak velocity variation; VE: volume expansion. |
