About this study

Official title: The Association of Norepinephrine Use in Pre-hospital Transport and Early Mortality in Hemorrhagic Shock

The effect of early, prehospital norepinephrine use in patients with traumatic shock on mortality is unknown. Recent existing observational evidence from single system data (US, France, Japan) are conflicting. The investigators hypothesize that prehospital norepinephrine is associated with decreased mortality when used in patients with traumatic shock.

Read the detailed description

Prehospital hypotension is associated with worse clinical outcomes in patients who sustain traumatic injuries. Administration of vasoactive medications, including norepinephrine, is not advocated in North American trauma systems due to the belief that vasopressors will worsen clinical outcomes and increase mortality. However, in European trauma systems prehospital vasopressor administration is included as part of the guidelines for the management of hypotension and hemorrhagic shock. There are multiple physiologic explanations for why prehospital vasopressor administration may be useful in patients with traumatic shock, such as providing adequate blood pressure to maintain vital signs until arrival at the trauma center, allowing adequate organ perfusion in the setting of low blood flow, and supplementing decreased hormone production in the later stages of hemorrhagic shock.

The purpose of this retrospective study is to investigate if prehospital norepinephrine administration is associated with decreased mortality in patients with traumatic shock. The investigators will collect patient data from previously collected sources of information and trauma databases from three separate locations: the TRAUMABase consortium in Paris, France; TRENAU trauma database from Grenoble, France; and the R Adams Cowley Shock Trauma Center in Baltimore, MD, USA. The investigators will perform statistical modeling to propensity score match patients that received prehospital vasopressors with patients that did not receive prehospital vasopressors and assess the association with 24-hour and 28-day mortality.

What participants receive

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

  • NorepinephrineDrug

    Trauma patients with prehospital or arrival to the trauma center hypotension, defined as a systolic blood pressure <100 mmHg, that received norepinephrine during prehospital transport or in the resuscitation unit.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Early mortality

    Death within 24-hours of admission to the trauma center

    Measured: Admission to the trauma center to 24-hours after admission

Secondary outcomes (1)
  1. 28-day mortality

    Death occurring within 28-days from admission to the trauma center

    Measured: Admission to the trauma center to 28-days after admission

Questions about this trial

What is this clinical trial studying?

An observational study of Traumatic Shock and Hemorrhagic Shock, run by University of Maryland, Baltimore.

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 4 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 10 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

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 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?

Early mortality (time frame: Admission to the trauma center to 24-hours after 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 NCT04497155, which also lists 5 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 10 Feb 2022.
