Study to Actively Warm Trauma Patients

April 16, 2021 updated by: Luis Teodoro da Luz, Sunnybrook Health Sciences Centre

STudy to ActivelY WARM Trauma Patients (STAY WARM): A Feasibility Pilot Evaluation

This study evaluates the feasibility of using thermal blankets to actively warm massively bleeding trauma patients at Sunnybrook Health Sciences Centre. It is hypothesized that either full thermal blankets or half thermal blankets will be a feasible intervention to implement for the care of massively bleeding trauma patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Hypothermia (core body temperature of <36˚C), is a strong risk factor for mortality and poor outcomes in trauma patients due to its negative hemostatic, cardiovascular, respiratory, and renal effects. Current evidence has reported that massively bleeding hypothermic trauma patients have higher odds of mortality in the first 24 hours of hospital admission, increased length of stay, and increased need for transfusion. Standard hospital blankets are used to passively warm patients through resuscitation and treatment until arrival to the ICU. Interventions such as active heating through thermal blankets should be considered to prevent and treat hypothermia upon arrival of patients than standard warmed hospital blankets to prevent deleterious outcomes in this population.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Any trauma patient requiring activation of the massive hemorrhage protocol (life- threatening bleeding situation requiring mobilization of blood bank, laboratory and clinical resources, and anticipated need for at least 4 units of red blood cells immediately and component therapy) during the hours when research staff are available. Normothermic (core body temperature between 36˚C or greater) will also be included, as core body temperature drops once resuscitation is initiated.
  • Hypothermic patients (temperature ≤ 35˚C) to whom MHP is NOT activated, when Dr. Luis da Luz/trauma fellow is on call as Trauma Team Leader will also be included.

Exclusion Criteria:

  • Patients known to be pregnant
  • Patients who die in the trauma bay
  • Patients excluded at the discretion of the TTL based on use of the blanket not appearing feasible given the sustained injuries, multiple procedures being conducted in the trauma, or patients who seem to have unsurvivable injuries.
  • Patients admitted during study off-hours.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Study blanket
Two standard warmed hospital blankets will be placed on top of the patient and the study blanket on top of the standard warmed blankets, covering as much of the patient as possible, at the discretion of the care team. At all times, clinicians should ensure that the study blanket does not touch the patient's bare skin.The blanket will remain on the patient through their path of care, and removed from the patient at arrival to the ICU/final phase of care, or if the patient temperature exceeds 38˚C at any point.
Device: Thermal Blanket
Ready-Heat 6-Panel Blanket (Military style, manufactured by Techtrade LLC). The 6-panel military-style blanket (86cm x 152 cm, 1.13kg) warms to 40˚C in approximately 15-20 minutes and maintains this temperature for 10 hours.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Was the blanket applied to the patient?
Time Frame: Through study completion, an average of 24 hours
Binary indication of whether or not the blanket is applied to the patient
Through study completion, an average of 24 hours
Were patient temperatures recorded?
Time Frame: Through study completion, an average of 24 hours
At least 2 temperature recordings (1 in the trauma bay and 1 in the next phase of care - CT scanner suite, angioembolozation suite, emergency department [ED], or operating room), or preferentially, at the final phase of care usually the ICU or ED
Through study completion, an average of 24 hours
Did the blanket remain on the patient?
Time Frame: Through study completion, an average of 24 hours
Binary indication of whether or not the blanket is kept on the patient in each phase of care until arrival to ICU (1, 2, 3, 4, 5, and 6-hours post initial application of the blanket)
Through study completion, an average of 24 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
