Trial summary

Anesthesia-related factors have been linked to poor perioperative outcomes. Our observational study suggested that the cumulative duration of a triple-low state [intraoperative low mean arterial pressure (MAP), low bispectral index (BIS), and low target effect-site concentration(Ce) ]was associated with poorer 30-day… Read more about this study

About this study

Official title: Effects of Perioperative Goal-Directed Therapy Based on Individualized Oxygen Balance on Outcomes During High-risk Cardiac Surgery:A Single Center, Prospective,Randomized,Controlled,Double Blinded Study.

Anesthesia-related factors have been linked to poor perioperative outcomes. Our observational study suggested that the cumulative duration of a triple-low state [intraoperative low mean arterial pressure (MAP), low bispectral index (BIS), and low target effect-site concentration(Ce) ]was associated with poorer 30-day mortality.This randomized, prospective study based on individualized Oxygen dynamics is designed to confirm this association in high-risk patients cardiopulmonary bypass (CPB).

What participants receive

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

  • mean artery pressureProcedure or surgery

    mean artery pressure declined with less than 20% of baseline

  • bispectral indexProcedure or surgery

    Also called BIS

    BIS 45-60 before and after CPB; and BIS 40-45 during CPB

  • Brain oxygen saturationProcedure or surgery

    Brain oxygen saturation declined with less than 20% of baseline

  • ControlledOther

    receiving standard measures to achieve a heart rate (HR) in the range of 60-100 beats/min, central venous oxygen saturation (Svco2) higher than 70%, lactate level lower than 3 mmol/L, hematocrit value higher than 28%, and urinary output higher than 0.5 mL/kg/hr.

What is being measured

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

  1. Major postoperative complications(i.e., Rate of low cardiac output syndrome, stroke, myocardial ischemia, infection,reoperation, and need for dialysis)

    Number of Participants with major complications extracted after 30-day follow-up

    Measured: 30-day after surgery

  2. 30-day mortality

    Data for duration of postoperative 30-day all-cause mortality

    Measured: 30-day after surgery

  3. The change of incidence of postoperative delirium

    Through Confusion Assessment Method (CAM)to assess the incidence of the postoperative delirium

    Measured: The 1,2,3 day after surgery

  4. 1,3,5-year mortality

    Data for duration of 1,3,5-year all-cause mortality is extracted after 1-year follow-up

    Measured: 1,3,5-year after surgery

Secondary outcomes (4)
  1. postoperative hospital stay

    Data for duration of postoperative hospital stay is extracted after 30-day follow-up

    Measured: 30-day after surgery

  2. The change of incidence of postoperative cognition dysfunction

    The neuropsychological tests performed at the day before the surgery,the 3,7 day after the surgery respectively.

    Measured: 1 day before surgery, the 3,7 day after the surgery

  3. The occurrence of cardiovascular events

    Data for duration of the occurrence of cardiovascular events is extracted 30-day follow-up

    Measured: 30-day after surgery

  4. The incidence of any adverse events

    Including kidney or brain related adverse events 30-day after surgery

    Measured: 30-day after surgery

Questions about this trial

What is this clinical trial studying?

A study testing mean artery pressure, bispectral index and Brain oxygen saturation in people with Cardiac Disease and High Risk Sex, run by The First Affiliated Hospital of Anhui Medical University 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 5 inclusion and 5 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 25 Mar 2019. 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. Some participants in this study may receive a placebo. 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?

Major postoperative complications(i.e., Rate of low cardiac output syndrome, stroke, myocardial ischemia, infection,reoperation, and need for dialysis) (time frame: 30-day after surgery). 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?

On the ClinicalTrials.gov record for NCT03103633, which also lists 1 linked publication.

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 25 Mar 2019.
