Hemodynamic Monitoring-Guided Goal-Directed Fluid Therapy in Robotic Radical Prostatectomy

This prospective observational cohort study evaluated goal-directed fluid therapy guided by minimally invasive hemodynamic monitoring in adult male patients undergoing elective robotic radical prostatectomy. Patients were prospectively enrolled and followed according to the intraoperative fluid management strategy used in routine clinical practice. Patients managed with LiDCO®Rapid-guided goal-directed fluid therapy constituted the hemodynamic monitoring-guided group, while patients managed with conventional intraoperative fluid therapy constituted the control group. No randomization or additional research-related intervention was performed. The study compared the two fluid management strategies with respect to intraoperative crystalloid fluid administration and selected perioperative clinical and laboratory parameters.
