WebSVV was used in fluid therapy in 48.9% of the patients. The use of SVV resulted in an increased use of crystalloids and colloids with increased urine output per hour ( p <0.05). Of patients in the SVV group and the CVP group, 44.1% and 51.1% developed at least one complication, respectively ( p =0.531). Weba low central venous pressure is important, it is known that low stroke volume variation may be associated with increased blood loss.
