Zero Heat Flux Temp Monitor on Discharge Hypothermia Among Trauma Patients (RUZIT Trial) (RUZIT)

The Relationship Between the Use of a Continuous a Zero-heat Flux Temperature Monitor on Initial Discharge Hypothermia Rate Among Severely Injured Trauma Patients: a Randomized Controlled Trial. (RUZIT Trial)

Hypothermia amongst trauma patients is a persistent problem that increases the relative risk of transfusion as well as morbidity and mortality. The investigators propose to conduct a single-centered randomized controlled trial to determine if the use of a zero-heat flux (ZHF) temperature monitor can reduce the incidence of hypothermia amongst trauma patients discharged from the trauma bay (TB). All eligible trauma patients will be randomized to either a standard of care group or an active temperature monitoring group. In the active temperature monitoring group, a ZHF monitor will be placed on respective trauma patients to continuously record their temperatures after they enter the TB at a large tertiary trauma centre, Sunnybrook Health Sciences Centre (SHSC), in Toronto, ON. The investigators will determine if early continuous temperature monitoring can reduce the incidence of hypothermia upon discharge from the TB. Should early monitoring of severely injured trauma patients within the hospital improves discharge temperature, the foundation for two additional research studies will be laid. Firstly, the investigators will enter a vanguard phase of this trial and assess if early warming patients can improve morbidity and mortality in this patient population utilizing a multi-centered randomized controlled trial design. This will be further extended to test whether early monitoring can be applied in a pre-hospital setting (i.e. within ambulances and transport vehicles) to improve admission temperatures in the TB.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Standard of Care Group; ZHF temperature monitor cable will be placed appropriately on the forehead by the care team under the direction of the research personnel. The research personnel will then connect this cable to a screen that is blinded to the care team but not to the research personnel.	Device: Standard of Care Group; ZHF temperature monitor cable will be placed appropriately on the forehead by the care team under the direction of the research personnel. The research personnel will then connect this cable to a screen that is blinded to the care team but not to the research personnel.
Experimental: Active Warming Group; ZHF temperature monitor cable will be placed appropriately on the forehead by the care team under the direction of the research personnel. The research personnel will then connect this cable to a screen that is un-blinded to everyone so healthcare practitioners will be able to visually detect continuous temperature readings from the ZHF monitor.
