About this study

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Philips Intelivue MP70 monitorDevice

    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.

  • Pleth Variability Index (PVI)Device

    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.

What is being measured

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

  1. Pulse Pressure Variation (PPV)

    Fluid responsiveness predictability of FTc and PVI in patients undergoing posterior lumbar fusion in the prone position by using the Jackson frame by calculating area under the curve of the ROC curve.

    Measured: From 15 minutes after induction of anesthesia in the supine position to 5 minutes after fluid loading in the prone position

  2. Pleth Variability Index (PVI)

    Measured: From 15 minutes after induction of anesthesia in the supine position to 5 minutes after fluid loading in the prone position

Questions about this trial

What is this clinical trial studying?

A study testing Philips Intelivue MP70 monitor and Pleth Variability Index (PVI) in people with Elective Posterior Lumbar Spinal Fusion for Spinal Stenosis and Spondylolisthesis, run by Yonsei University at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pulse Pressure Variation (PPV) (time frame: From 15 minutes after induction of anesthesia in the supine position to 5 minutes after fluid loading in the prone position). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Oct 2017.
