Use of fluid therapy in perioperative adult patients: A narrative review.

The administration of intravenous fluids is the most common intervention in hospitalised patients in the perioperative setting and critical care units. The aim of this narrative review is to provide an overview of balanced solutions for fluid therapy in the perioperative period in adult patients, and to review new trends and solutions in fluid therapy. The evidence was grouped into 3 areas: intraoperative fluid administration, fluid administration in critically ill patients, and the importance / benefit of balanced crystalloid solutions. Although a number of high-quality studies have been published in recent years, the scientific evidence regarding the type of fluid, the dose, and rate of administration is still limited. The choice of fluid therapy during the perioperative period must be tailored to patient-specific factors, the nature of the surgery, expected fluid loss, and other relevant factors. Finally, more robust clinical evidence and physician training is of the utmost importance.
