Summary

Appropriate fluid management is an important part of anesthesia in patients undergoing surgery, and several dynamic indices have been suggested to have high predictability for fluid responsiveness in patients receiving mechanical ventilation. Among various surgical positions, the prone position is known to cause unique physiologic and hemodynamic changes and affect the predictability and cut-off values of dynamic indices for fluid responsiveness. A previous study reported that pulse pressure variation (PPV) and corrected flow time were able to predict fluid responsiveness with relatively high accuracy in patients undergoing spine surgery in the prone position using a Wilson frame. However, the Jackson frame is known to have less effects on the cardiovascular system compared to the Wilson frame, and therefore may be physiologically more appropriate in patients undergoing surgery in the prone position. The pleth variability index (PVI) is a dynamic index that can be monitored non-invasively in patients under mechanical ventilation. The present study aims evaluate the validity of PPV and pleth variability index (PVI) as predictors of fluid responsiveness in the supine and prone positions in patients undergoing posterior lumbar spinal fusion using the Jackson table.

Conditions

  • Elective Posterior Lumbar Spinal Fusion for Spinal Stenosis
  • Spondylolisthesis
  • Spinal Fractures
  • Scoliosis or Tumors

Interventions

DEVICE

Philips Intelivue MP70 monitor

Philips Intelivue MP70 monitor (Intellivue MP70, Philips medical Systems, Suresnes, France) -a radial arterial cannula is inserted and arterial pressure waveforms are monitored through Philips Intelivue MP70 monitor. In the monitor, PPVauto is displayed in real-time. It is based on automatic detection algorithms, kernel smoothing, and rank-order filters.

DEVICE

Pleth Variability Index (PVI)

PVI is the measure of the dynamic changes in the Perfusion Index (PI) that occur during one or more complete respiratory cycles. A rainbow Pulse CO-Oximetry sensor is attached to the patient's finger and the PVI is displayed in real-time on the Root monitor.
