Text: Although the hemodynamic measurements after spinal anesthesia remained stable in group H throughout the observation period, blood pressure, central venous pressure, pulmonary artery (PA) wedge pressure and systemic vascular resistance decreased significantly in group R (blood pressure : -7 + / - 10 vs - 14 + / - 8 % 30 minutes after spinal anesthesia, P <. 05 to group R ; central venous pressure : 51 + / - 106 vs -26 + / - 27 % 10 minutes, 63 + / - 89 vs -36 + / - 30 % 20 minutes and 73 + / - 112 vs -33 + / - 29 % 30 minutes after spinal anesthesia, P <. 01 to group R ; PA wedge pressure : 40 + / - 37 vs -5 + / - 40 % 10 minutes, 40 + / - 35 vs -23 + / - 32 % 20 minutes and 38 + / - 36 vs -23 + / - 32 % 30 minutes after spinal anesthesia, P <. 01 to group R ; systemic vascular resistance : -10 + / - 16 vs -18 + / - 7 % 20 minutes and -10 + / - 15 vs - 19 + / - 12 % 30 minutes after spinal anesthesia, P <. 05 to group R).
