Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Reliable and valid assessment of burn wound depth or healing potential is essential to treatment decision-making, to provide a prognosis, and to compare studies evaluating different treatment modalities. Clinical evaluation remains the most widely used method for assessing the depth of the burn wound. This method is based on the subjective evaluation of visual and tactile characteristics of the wound, with an accuracy ranging between 50 to 70%; which is not precise to guide clinical decision making. The aim of these study is to validate thermography as a therapeutic approach to predict treatment modality based on thermographic imaging of the wound and its healing potential obtained during the first three days of treatment of either healing by re-epithelization, requiring skin grafts, or requiring amputations. By performing this algorithm, it is expected to address three aspects of the management of patients with acute burns: early clinical diagnosis, initial management decisions and reduction of hospitalization days.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Burn wounds are divided into first degree burns involving the epidermis, superficial second degree with lesion of the papillary dermis, deep second degree with lesion of the reticular dermis, third degree with lesion to the hypodermis, and fourth degree involves fascia, muscle, tendons and bone.

In burns, development and severity of complications are in direct proportion to the magnitude of the burn. The magnitude of the damage depends on three factors, the duration of the contact, the intensity of the current or temperature and the resistance offered by the tissue. The extent of the burned skin surface is very useful to assess the severity of the patient, it is a relevant criterion to develop the prognosis. It is important to have comprehensive knowledge of the burned patient and close collaboration with the multidisciplinary care team through a careful evaluation that includes mechanism of injury, type, extent, degree of affectation and organic repercussion of the burn. The reliable and valid evaluation on the depth of a burn wound or the healing potential is essential for the decision making in the treatment; to provide a prognosis and to compare the different treatment modalities. There is no gold standard in the evaluation of burns.

Infrared imaging is a non-invasive technique that quantifies the temperature of the body surface by capturing the thermal radiation emitted and producing a high-resolution digital image called a thermogram. The presence of a disease interferes locally with the heat balance, which results in an increase or decrease in the temperature of the skin, in comparison to the surrounding regions or the contralateral not affected region. A degree of thermal asymmetry between opposite sides of the body (ΔT) of up to 1 ° C has been considered indicative of dysfunction. In several previous studies the parameters of initial thermography between the wound and healthy skin (delta T) were defined, to decide the therapeutic approach of the burns to predict the evolution: ΔT \<3º C epithelialized with conservative treatment, ΔT 3-5º C should be graft early and ΔT\> 5º C should be amputated.Thermography offers a feasible option for valuation.

Methods:

This is randomized clinical study of patients with different burn depth. All patients will be examined using a thermal camera.

Expected Results:

In all cases, the investigators obtained infrared images that corroborate clinical findings.

Participants Outcome Assessors

Controlled double blinded study. Patients and outcomes assessors will be masked to intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Current treatment

Patients will receive burn care treatment as dictated by the surgical team (current standard of care).

Group Type ACTIVE_COMPARATOR

Current treatment

Intervention Type OTHER

Digital infrared thermograms will be obtained during the first contact with the patients. Temperature recordings of the injured and healthy skin will be used to calculate the temperature difference between the structures, but the results will be kept sealed until the study is finished. The patients will receive the usual standard of care as dictated by the surgical team.

Algorithm-dictated treatment

Patients will receive burn care treatment as dictated by the treatment algorithm (PLOS ONE 13(11): e0206477.).

Group Type EXPERIMENTAL
