Patients in group LR received intraoperative placebo Lactate Ringers’ at a dose of 7.5 ml/kg; Patients in group HES received 6% HES 130/0.4 at a dose of 7.5 ml/kg in the first hour of surgery, and then, Lactate Ringers’ was administrated 5 ml/kg until the end of the surgery. Haemodynamics data was evaluated and recorded at baseline (T0), before skin incision (T1), skin incision (T2), after skin incision (T3), surgery completed (T4). All data were presented as mean ± SD.
