Abstract

Background: Perioperative fluid therapy is used to avoid dehydration and hypovolemia. Optimum perioperative fluid administration may improve postoperative outcomes after major surgery, and the optimal strategy remains controversial and uncertain. Aims: The primary outcome was the total amount of intraoperative fluids given between perioperative goal-directed fluid therapy (GDFT) guided by a hemodynamic monitoring system and standard fluid therapy based on "mean arterial pressure-diuresis" data in patients undergoing head and neck surgery. The secondary outcomes were the hemodynamics and laboratory variables, postoperative complications, length of mechanical ventilation, intensive care unit and hospital stay. Study Design: A randomized controlled study Methods: Sixty patients were scheduled and randomized into two groups of 30 patients each: in the study group, an arterial pressure catheter was inserted and connected to the FloTrac system, whereas in the control group, an arterial pressure catheter was inserted and integrated into the hemodynamic monitoring system with a special transducer. The control group had fluids administered at the discretion of the anesthesiologist according to the mean arterial pressure >65 mmHg and diuresis >0.5 ml/kg/h. In the study group, fluid management was administered to achieve a target value of <= 13% through the stroke volume variation. Results: The total amounts of fluid in the intraoperative period were different between the groups, with the study group receiving significantly more fluids (P = 0.0455). The length of hospital stay was significantly longer in the study group than in the control group (P = 0.012), but prolonged oxygen demand was significantly more frequent in the control group than in the study group (P = 0.017). No difference was found in hemodynamics, lactate kinetics, and vasoactive agent requirements. Conclusion: The standard fluid therapy guided by conventional circulatory parameters appears sufficient for patients with low-to -moderate risk during head and neck surgery.
