Summary

This prospective study aims to evaluate the hemodynamic effects of different surgical positions-supine, lithotomy, and prone-in patients undergoing percutaneous nephrolithotomy (PCNL). Hemodynamic parameters are assessed using the Pressure Recording Analytical Method (PRAM) both while patients are awake and under general anesthesia. The study investigates how positioning-independently and in combination with anesthesia-influences cardiovascular function, including mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), stroke volume index (SVI), pulse pressure variation (PPV), stroke volume variation (SVV), cardiac contractility parameters (dP/dtmax), arterial elastance (Ea), cardiac power index (CPI), and cardiac cycle efficiency (CCE). The findings are expected to contribute to optimizing perioperative management and enhancing patient safety during PCNL procedures.

Conditions

  • Hemodynamic Changes
  • Surgical Positioning
  • Percutaneous Nephrolithotomy (PCNL)

Interventions

OTHER

Position the patient

In addition, prior to the operation and throughout the PCNL procedure, hemodynamic measurements were obtained while patients were positioned in the supine, lithotomy, and prone positions, as necessitated by the surgical protocol.
