About this study

Official title: Rapid Infusion of Ringer's Lactate Solution At Different Temperatures and the Effects on Circulation and Perfusion in Healthy Volunteers - a Randomized Crossover Trial

In this single center crossover study the aim is to investigate the effect of Ringer's lactate solution at high and low temperatures on physiological response in healthy adults.18 healthy volunteers will be included. Inclusion criteria is; Age between 18-64. Exclusion criteria is; Pre-existing medical problems, Pregnancy (validated through a certified pregnancy test), Body mass index >35 kg/m2, Medication use apart from allergy medication, contraceptives, or non-steroidal anti-inflammatory drugs.

Participants will be randomized to receive 30 ml/kg of Ringer's lactate either cold (15°C, 59°F), or at body temperature (37°C, 98.6°F) during a 30-minute interval. Fluids will be administered through a peripheral vein. After a minimum "washout period" of 24 hours, subjects are switched to receive infusion at the other aforementioned temperatures.

Primary outcome is

  • The increase in MAP at 15 minutes after infusion of the fluid bolus. Secondary outcome is
  • Time until return of MAP to baseline value after infusion.
Being tested
Ringer's Lactate

What participants receive

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

  • Ringer's LactateDrug

    On the first trial day healthy volunteers are randomized to receive 30 ml/kg of Ringer's lactate either cold (15°C, 59°F), or at body temperature (37°C, 98.6°F) during a 30-minute interval. After a minimum "washout period" of 24 hours, subjects are switched to receive infusion at the other aforementioned temperatures.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ringer's Lactate in people with Hemodynamic Instability, run by Esbjerg Hospital - University Hospital of Southern Denmark at 1 site in Denmark.

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 1 inclusion and 4 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 5 Sep 2024. 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 Denmark. 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?

Increase in MAP at 15 minutes after infusion of the fluid bolus. (time frame: 15 minutes). 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 NCT05610254, 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 5 Sep 2024.
