Trial summary

Fluid treatment is usually performed with either balanced crystalloid fluids or iso-oncotic colloids, (synthetic colloids, plasma and 5% albumin). Doubts have been raised about synthetic colloids (impairment of renal function and coagulation), and the natural albumin has been used more extensively. Read more about this study

About this study

Official title: Impact of Hyperoncotic Albumin to Support Blood Loss Replacement on Plasma Volume Expansion in Cystectomy Patients.

Fluid treatment is usually performed with either balanced crystalloid fluids or iso-oncotic colloids, (synthetic colloids, plasma and 5% albumin). Doubts have been raised about synthetic colloids (impairment of renal function and coagulation), and the natural albumin has been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. An alternative therapeutic option is the mobilization of tissue fluid by infusing a small amount of hyper-oncotic fluid like the 20% albumin solution (endogenous fluid recruitment).

The primary objective of this study is to test the effect of 20% albumin on plasma volume expansion and fluid recruitment in the frame of blood loss replacement during cystectomy using established fluid kinetic models.

The investigators expect that fluid replacement with crystalloid will be better sustained intravascularly with the administration of 20% albumin and be able to recruit fluid into the vascular compartment.

Read the detailed description

Bladder cancer occurs mainly in old comorbid patients. The standard treatment of localized muscle invasive bladder cancer is pelvic lymph node dissection and open radical cystectomy with urinary diversion. Optimal perioperative fluid management for this surgery is challenging and still controversial in terms of how much to perfuse, choice of fluids (crystalloids and colloids) to restore hydrated state and volemia.

Fluid treatment is usually performed with either balanced crystalloids fluids or iso-oncotic synthetic colloids, plasma or 5% albumin. Because crystalloids quickly equilibrate between the intravascular and interstitial volumes, they are mainly used to treat dehydration and temporary volume deficits. Iso-oncotic colloids remain intravascular for a prolonged period. Doubts have been raised about synthetic colloids, and the natural albumin has been used more extensively. Albumin is the main protein responsible for plasma oncotic pressure and its volume expansion effect. An alternative therapeutic option is the mobilization of tissue fluid by infusing a small amount of hyper-oncotic fluid like the 20% albumin solution (endogenous fluid recruitment).

There are still unknown aspects of the physiological effects of hyper-oncotic albumin. One of them is the, in this study investigated, effect of 20% albumin on plasma volume expansion, fluid recruitment, and crystalloid kinetic in the frame of blood loss replacement during cystectomy.

It is expected that fluid replacement with crystalloid will be better sustained intravascularly with the administration of 20% albumin.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing albumin 20% in people with Blood Loss, Surgical and Fluid Retention, run by Insel Gruppe AG, University Hospital Bern at 1 site in Switzerland.

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 6 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 20 Feb 2020. 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 Switzerland. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Plasma volume expansion (time frame: 5 hours). 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 NCT03848507, which also lists 2 linked publications.

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 20 Feb 2020.
