About this study

Official title: Comparison of Positive End-expiratory Pressure-induced Increase in Central Venous Pressure and Stroke Volume Variation to Predict Fluid Responsiveness in Robot-assisted Laparoscopic Surgery: A Prospective Clinical Trial

In urologic robotic surgery with steep Trendelenburg position, maintenance of cardiac preload and cardiac output is important for clinical prognosis. Previous studies reported the positive end-expiratory pressure (PEEP)-induced increase in central venous pressure (CVP) could be a accurate predictor of fluid responsiveness in cardiac surgical patients. The authors attempt to evaluate the predictability of PEEP-induced increase in CVP as well as stroke volume variation in urologic robotic surgery with Steep Trendelenburg position.

Read the detailed description

In urologic robotic surgery with steep Trendelenburg position, maintenance of cardiac preload and cardiac output is important for clinical prognosis. As a preload index, the predictability of central venous pressure, pulse pressure variation and stroke volume variations may be impaired due to the impaired hemodynamics that result from the effect of increased abdominal pressure and decreased venous return. Previous studies reported the positive end-expiratory pressure (PEEP)-induced increase in central venous pressure (CVP) could be a accurate predictor of fluid responsiveness in cardiac surgical patients. Therefore, the authors attempt to evaluate the predictability of PEEP-induced increase in CVP as well as stroke volume variation in urologic robotic surgery with Steep Trendelenburg position.

What participants receive

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

  • Fluid loading of volulyte 300 mlProcedure or surgery

    Administration of volulyte 300 ml and measurement of increase in cardiac index

Study groups in NCT02977143
Study groupRoleWhat they receive
Fluid responsiveness testExperimentalFirst, apply 10 cmH2O positive endexpiratory pressure (PEEP) and measure the increase in central venous pressure (CVP) as well as other preload indexes (central venous pressure, mean arterial pressure, stroke volume variation). Second, measure the increase in cardiac index after administration of volulyte 300 ml. If cardiac index increase more than 10%, fluid responsiveness is confirmed.

Questions about this trial

What is this clinical trial studying?

A study testing Fluid loading of volulyte 300 ml in people with Prostatic Neoplasm and Urinary Bladder Neoplasm, run by Seoul National University Hospital 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 2 inclusion and 4 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 3 Apr 2018. 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?

fluid responsiveness (time frame: 5 minutes after administration of 300 ml volulyte). 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 3 Apr 2018.
