About this study

Official title: Preliminary Study on the Changes of Perioperative Circulatory Function in Patients Undergoing Laparoscopic Radical Cystectomy for Bladder Cancer

To optimize the perioperative management of patients undergoing laparoscopic radical cystectomy(LPC) for bladder cancer through observation of perioperative changes of Brain Natriuretic Peptide(BNP), stroke volume variation(SVV), central venous pressure(CVP) and the use of transthoracic echocardiography(TTE).

Read the detailed description

Long term pneumoperitoneum and steep trendelenburg in LPC for bladder cancer influence perioperative circulatory function, resulting in a series of pathophysiological changes. BNP is of high sensitivity and specificity in the evaluation of cardiac function. SVV and CVP are dynamic and static indices to predict fluid responsiveness. TTE is a good indicator of volume and cardiac function.Thus, we conducted the trial to assess the perioperative circulatory function in patients undergoing LPC. We hypothesized that long term pneumoperitoneum and steep trendelenburg in LPC for bladder cancer would increase perioperative blood volume and influence cardiac function.

What is being measured

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

  1. Brain Natriuretic Peptide(BNP)

    To observe the change of BNP perioperatively.

    Measured: before induction (T1), at the end of operation(T2), at 12 hours (T3) and 24 hours (T4) postoperatively

  2. Central Venous Pressure(CVP)

    To observe the change of CVP perioperatively.

    Measured: before induction (T1),at the end of operation (T2), at 12 hours (T3) and 24 hours (T4) postoperatively

  3. Stroke Volume Variation(SVV)

    To observe the change of SVV perioperatively.

    Measured: before induction (T1), at the end of operation (T2)

  4. Transthoracic Echocardiography

    To observe the change of End-diastolic volume(EDV) perioperatively

    Measured: before induction (T1),at the end of operation (T2), at 12 hours (T3) and 24 hours (T4) postoperatively

Questions about this trial

What is this clinical trial studying?

An observational study of Circulatory Function and Laparoscopic Radical Cystectomy for Bladder Cancer, run by RenJi Hospital at 1 site in China.

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 3 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 17 Feb 2022. 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 China. 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?

Brain Natriuretic Peptide(BNP) (time frame: before induction (T1), at the end of operation(T2), at 12 hours (T3) and 24 hours (T4) postoperatively). The study lists 4 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 17 Feb 2022.
