About this study

Official title: The Effect of Perioperative Cardiac Output-guided Goal-directed Hemodynamic Therapy (GDT) on Perioperative Oxygen Delivery, Consumption, and Microcirculatory Perfusion in Comparison to Routine Hemodynamic Management

Perioperative cardiac output-guided goal-directed therapy (GDT) triggers fluid, vasopressor, and inotrope administration assuming that optimizing cardiac output (i.e., global blood flow) ensures adequate oxygen delivery and microcirculatory perfusion - that are usually not directly monitored during goal-directed therapy. There is increasing evidence that perioperative cardiac output-guided goal-directed therapy may reduce postoperative complications compared to routine hemodynamic management in high-risk patients having major surgery. The effect of cardiac output-guided goal-directed therapy algorithms on perioperative oxygen delivery and consumption as well as microcirculatory perfusion, however, is unknown.

The investigators aim to investigate the effect of using different cardiac output-guided goal-directed therapy algorithms on perioperative oxygen delivery and consumption as well as sublingual microcirculatory perfusion compared to routine perioperative hemodynamic management in patients having major abdominal surgery with general anesthesia.

Perioperative cardiac output-guided goal-directed therapy (GDT) triggers fluid, vasopressor, and inotrope administration assuming that optimizing cardiac output (i.e., global blood flow) ensures adequate oxygen delivery and microcirculatory perfusion - that are usually not directly monitored during goal-directed therapy. There is increasing evidence that perioperative cardiac output-guided goal-directed therapy may reduce postoperative complications compared to routine hemodynamic management in high-risk patients having major surgery. The effect of cardiac output-guided goal-directed therapy algorithms on perioperative oxygen delivery and consumption as well as microcirculatory perfusion, however, is unknown.

With technological advancements a distinct monitoring of oxygen delivery and consumption as well as microcirculatory perfusion in the perioperative period has become possible. Using new technologies, a detailed understanding of the effect of cardiac output-guided goal-directed therapy on perioperative oxygen delivery and consumption as well as microcirculatory perfusion is of vital importance to further develop and improve perioperative hemodynamic treatment strategies.

In this pilot randomized-controlled trial, the investigators therefore aim to investigate the effect of using different cardiac output-guided goal-directed therapy algorithms on perioperative oxygen delivery and consumption as well as sublingual microcirculatory perfusion compared to routine perioperative hemodynamic management in patients having major abdominal surgery with general anesthesia.

What is being measured

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

  1. Perioperative changes in oxygen delivery

    assessed via blood gas analysis

    Measured: after induction of general anesthesia, during the last 30 minutes of surgery, within 6 hours after surgery, day 1, 2, 3 after surgery

  2. Perioperative changes in oxygen consumption

    assessed via indirect calorimetry

    Measured: baseline awake, after induction of general anesthesia, during the last 30 minutes of surgery, within 6 hours after surgery, day 1, 2, 3 after surgery

Secondary outcomes (2)
  1. Perioperative changes of microcirculation

    assessed via Incident Darkfield technology

    Measured: baseline awake, after induction of general anesthesia, during the last 30 minutes of surgery, within 6 hours after surgery, day 1, 2, 3 after surgery

  2. Perioperative changes in cardiac output

    assessed via pulse wave analysis

    Measured: baseline awake, after induction of general anesthesia, during the last 30 minutes of surgery, within 6 hours after surgery, day 1, 2, 3 after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Treatment algorithms targeting cardiac output in people with Caridac Output-guided Goal-directed Hemodynamic Therapy and Oxygen Delivery, run by Universitätsklinikum Hamburg-Eppendorf at 1 site in Germany.

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 3 inclusion and 12 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 30 Jun 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 Germany. 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?

Perioperative changes in oxygen delivery (time frame: after induction of general anesthesia, during the last 30 minutes of surgery, within 6 hours after surgery, day 1, 2, 3 after surgery). 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 30 Jun 2022.
