About this study

Official title: Comparison Between Two Techniques of Volemic Expansion in Hip Replacement Arthroplasty: Hydroxyethyl Starch Versus Ringer's Lactate

Currently the most use solution to volemic reposition in hip replacement arthroplasty is the crystalloid solution. This trial intends to compare two different volemic replacements: HES and Ringer's lactate. This research has been analyzing hemodynamic parameters and the coagulation status before and after the pre-expansion with the solutions above mentioned.

Read the detailed description

This trial is randomized an blind to the physician who is analyzing the results.It has been select adults; both sex; ASA I and II. These patients must be submitted to hip arthroplasty replacement. The anesthesia technique is single shot spinal anesthesia. Primary endpoint: assessment alternative; technique replacement volemic with HES 130/04. Secondary endpoint: haemostatic abnormalities; blood loss; transfusion blood.

Being tested
Hydroxyethyl Starch, Ringer's lactate
Keywords
Hip Replacement Arthroplasty, Hydroxyethyl Starch, Hemodilution, Hetastarch, Colloids

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Hydroxyethyl Starch and Ringer's lactate in people with Hip Replacement Arthroplasty, run by University of Sao Paulo at 1 site in Brazil.

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 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 19 Feb 2009. 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 Brazil. 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?

HES expansion plasmatic efficacy (time frame: 24 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 NCT00542516, which also lists 8 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 19 Feb 2009.
