This group will have fluid theraphy due to conventional methods. The participants in this group will have 8-10 ml/kg/hour cristalloid infusion. If the mean arterial pressure (MAP) is <65 mmHg or the decrease in MAP is more than 20%, 250 ml iv colloid will be applied. If the decrease in MAP continues despite the colloid bolus or if the MAP is below 65 mmHg, noradrenaline infusion will be started.
Patients in the PVI group will be started on maintenance fluid therapy at 2-3 ml / kg / hour. In addition to standard monitoring, if PVI is <13% and OAB≥65mmHg in measurements made with PVI, current fluid therapy will continue. If PVI is <13% and MAP <65 mmHg, noradrenaline infusion will be started. If PVI is> 13% and OAB≥65 mmHg, 250 ml iv colloid bolus will be administered, and iv colloid bolus will be continued until the PVI is <13% in the 5-minute follow-ups. If PVI> 13% and MAP <65 mmHg, patients should receive 250 ml i.v. colloid infusion will be given, if MAP <65mmHg continues in 5 minutes follow-up, 250 ml i.v. Colloid and noradrenaline infusion will be started and repeated until the OAB≥65 mmHg and PVI <13%.
