About this study

Official title: Effectiveness of Goal-Directed Fluid Therapy Guided by Minimally Invasive Hemodynamic Monitoring in Robotic Radical Prostatectomy: A Prospective Observational Study

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.

Read the detailed description

This prospective observational cohort study was conducted in adult male patients undergoing elective robotic radical prostatectomy. The study compared two intraoperative fluid management strategies used in routine clinical practice: conventional fluid therapy and goal-directed fluid therapy guided by minimally invasive hemodynamic monitoring.

In the goal-directed fluid therapy group, intraoperative fluid management was guided by the LiDCO®Rapid hemodynamic monitoring system. A baseline crystalloid infusion of 2 mL/kg/hour was administered. Additional fluid boluses were given according to hemodynamic assessment, particularly when stroke volume variation (SVV) exceeded 15%. Hemodynamic parameters monitored included stroke volume variation, stroke volume, pulse pressure variation, systemic vascular resistance, and cardiac index.

In the conventional fluid therapy group, patients received crystalloid fluid at approximately 4 mL/kg/hour. Additional fluid administration was determined by the attending anesthesiologist according to routine clinical assessment and standard intraoperative monitoring.

All patients underwent standard anesthetic management and routine invasive arterial blood pressure monitoring. Assignment to the fluid management strategy was not randomized and reflected the clinical management approach used during surgery. No additional therapeutic intervention was performed solely for research purposes. Perioperative clinical, hemodynamic, laboratory, and fluid balance data were prospectively recorded for comparison between the two groups.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total intraoperative crystalloid fluid volume administered

    Total volume of crystalloid fluid administered during the intraoperative period in patients undergoing robotic radical prostatectomy.

    Measured: From anesthesia induction to the end of surgery, assessed over approximately 5 hours.

Secondary outcomes (5)
  1. Perioperative changes in arterial blood lactate levels

    Arterial blood lactate levels measured at baseline, at 2-hour intervals during surgery, and at 8 hours after the end of surgery.

    Measured: From baseline measurement at the beginning of surgery to 8 hours after the end of surgery.

  2. Incidence of intraoperative vasopressor use

    Number of participants requiring any vasopressor administration during the intraoperative period.

    Measured: From anesthesia induction to the end of surgery, assessed over approximately 5 hours.

  3. Postoperative blood urea nitrogen (BUN) change

    Change in blood urea nitrogen (BUN) level from the preoperative baseline value to the postoperative 8th-hour value.

    Measured: From preoperative baseline measurement to 8 hours after the end of surgery.

  4. Postoperative serum creatinine change

    Change in serum creatinine level from the preoperative baseline value to the postoperative 8th-hour value.

    Measured: From preoperative baseline measurement to 8 hours after the end of surgery.

  5. Postoperative estimated glomerular filtration rate (eGFR) change

    Change in estimated glomerular filtration rate (eGFR) from the preoperative baseline value to the postoperative 8th-hour value.

    Measured: From preoperative baseline measurement to 8 hours after the end of surgery.
