About this study

This project seeks to determine the effect of prehospital resuscitation with hypertonic saline vs. conventional crystalloids on the inflammatory response after injury. The leading cause of late mortality following injury is multiple organ dysfunction syndrome (MODS), which results from a dysfunctional inflammatory response after injury. Previous studies suggest that hypertonic saline may be beneficial by modulating this initial response and decreasing subsequent organ injury. This project takes advantage of a unique opportunity, afforded by an NIH-funded multi-center clinical trial of hypertonic resuscitation (conducted by the Resuscitation Outcomes Consortium), to obtain blood samples from patients enrolled in this trial to analyze inflammatory responses early after hypertonic vs. conventional resuscitation. This study was an ancillary study to the main randomized clinical trial and thus prospective observational in nature

The proposed study will be carried out in experiments grouped in three Specific Aims: Aim 1 provides a thorough investigation of the immunomodulatory response following hypertonic resuscitation with regard to neutrophil, monocyte, and T cell responses at serial time points after injury and resuscitation. Aim 2 comprises experiments to investigate the mechanisms by which hypertonicity may alter inflammatory cell signaling. Aim 3 seeks to correlate the laboratory findings with clinical endpoints reflective of immune dysfunction including inflammation, organ failure, nosocomial infection, and sepsis.

The investigators hypothesize that hypertonic resuscitation will be associated with modulation of the excessive inflammatory response seen after injury and thus will result in reduced rates of inflammatory organ injury.

Read the detailed description

This was an ancillary study to the larger clinical trials of prehospital hypertonic resuscitation conducted by the resuscitation outcomes consortium. This study investigated markers of immune function and coagulation in a subset of patients enrolled in the larger trials at two of the clinical sites. Four publications detail the results please see references

What participants receive

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

  • hypertonic salineDrug

    Also called hypertonic saline with dextran

    patients in parent trial were randomized to 250cc 7.5% saline, 7.5%saline with 6%dextran or normal saline as control as the initial resuscitation fluid after injury with signs of either hemorrhagic shock or severe traumatic brain injury

Questions about this trial

What is this clinical trial studying?

An observational study of Hemorrhagic Shock and Traumatic Brain Injury, run by University of Washington at 2 sites in 2 countries.

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 8 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: stopped early, as of the sponsor's last update on 1 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States, Canada. 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 was stopped early (reason given: Enrollment in the clinical trial was stopped for futility). Results are not available in the source record.

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?

neutrophil activation (time frame: Emergency department admission). 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 NCT00750997, which also lists 4 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 1 May 2017.
