Warm-up Efficiency by Body Warmer Versus Standard Procedure in Severely Traumatized Patients

Evaluation of Warm-up Efficiency by Body Warmer Versus Standard Procedure in Severely Traumatized Patients During Pre-hospital Medical Management

Study of adult patients with severe all-cause trauma having a body temperature less than 36°Celsius (C) that is managed by a Mobile Emergency Service team and oriented towards a Vital Emergency Room.

Currently two devices are used to warm patients during their care at the scene of an accident: a survival blanket and heating in the emergency vehicle. Despite these two devices many patients arrive in hypothermia (body temperature less than 36°C) in emergency departments. The objective of this study is to evaluate the effectiveness of a body warmer associated with standard warming devices on the correction of hypothermia compared to the standard procedure in severely traumatized patients with hypothermia .

It is a national multicentric study with 14 participating Mobile Emergency Service centers and hopefully will include 612 patients.

The study will be carried out according to a pattern of 28 successive periods of one week each during the winter period (October to April), for a total duration of 7 months. 14 action periods ON (warming standard procedure + body warmer) and 14 control periods OFF (warming standard procedure) will be run in random order for each center.

Inclusion Criteria:

• Major patient with all-cause trauma Grade A or B
• Patient with a trans-tympanic body temperature of less than 36°Celsius (C) at primary management by terrestrial or heliport Mobile Emergency Service team.

Exclusion Criteria:

• Patient initially supported by a pre-hospital medical team who does not participate in the study,
• Patient with cardiopulmonary arrest at initial pre-hospital medical team management,
• Patient with bilateral otorrhagia (due to the non-feasibility of trans tympanic temperature),
• Patient with inguinal crease or subclavicular fossa injury,
• Patient with severe burn (Burnt Body Surface> 20%),
• Patient deprived of liberty including patients with an electronic bracelet.
