Ensuring adequate fluid therapy in the perioperative period have a significant role on meeting the increased metabolic requirements and the prevention of postoperative complications. In general fluid treatment methods called as restrictive or liberal have been implemented for maintaining fluid balance in the perioperative period. These methods are based on calculation of the known or estimated fluid loss. In recent researches have shown that implemented fluid therapy according to these methods may be excessive or insufficient and may cause problems like fluid loading and hypovolemia. Today to avoid all these problems, individual goal directed fluid therapy is recommended in perioperative period. In individual goal directed fluid therapy amount and type of fluid to be applied have been selected cosidering individual characteristics of patients and treatment have been implemented under the guidance of determined hemodynamic criteria. In this article, information concerning the implemented fluid treatment methods for surgical patients in the perioperative period is presented.
