Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Male or female adult patients ≥18 years of age. Women of child bearing potential must test negative on standard pregnancy test (urine or serum) (as soon as possible during emergency care)
  • Patients with blunt or penetrating trauma suffering from estimated blood loss of ≥ 500 ml
  • Initial surgery deemed necessary within 24 hrs after trauma
  • Deferred signed written form or as locally required
  • No signs of intracranial or cerebral hemorrhage
  • Administration of less than 15 ml/kg body weight colloid between trauma injury and hospital admission.

Exclusion criteria

Exclusion:

  • to the active substances or to any of the other of the Products
  • Body weight ≥ 140 kg
  • Patients expected to die within 24h after traumatic injury
  • Sepsis
  • Burns
  • Renal impairment (AKIN stage ≥ 1 or chronic) or acute and/or chronic Renal Replacement Therapy
  • Critically ill patients (typically admitted to the intensive care unit)
  • Hyperhydration
  • Pulmonary edema
  • Dehydration
  • Hyperkalemia
  • Severe hypernatremia
  • Severe hyperchloremia

  • Metabolic alkalosis
  • Simultaneous participation in another interventional clinical trial (drugs or medical devices studies)
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 5, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
