What is the purpose of this trial?

This project will identify the efficacy of cooling modalities aimed to attenuate excessive elevations in skin and internal body temperatures, and associated indices of cardiovascular stress, during physical activity in well-healed burn survivors. The investigators will conduct a randomized crossover design study. Non-burned control subjects and subjects who experienced burns covering 20% or more of their body surface area will be investigated. Subjects will exercise in heated environmental conditions while receiving no cooling (control) as well as skin wetting.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it excludes people with chronic medical conditions requiring regular therapy, like heart disease, cancer, diabetes, and hypertension.

Is cooling with water spray and fan safe for treating burns?

Research shows that cooling methods like water spray and fan are generally safe for treating burns, as they help reduce skin temperature and relieve pain without causing harm. ^{1 2 3 4 5}

How does the Water Spray and Fan treatment for burns differ from other treatments?

The Water Spray and Fan treatment for burns is unique because it combines water spray with fan use to enhance evaporative cooling, which can be more effective in reducing skin temperature compared to other methods like wet towels or burn-cooling blankets. This method leverages the cooling effect of evaporation, which is not as effectively utilized in treatments that rely solely on direct application of water or cooling products. ^{1 2 3 6 7}

What data supports the effectiveness of the treatment Water Spray and Fan, Water Spray and Fan, Skin Wetting and Fan Use, Evaporative Cooling Methods for burns?

Research shows that using cool running water or water spray can help reduce skin temperature and relieve pain in burn injuries. Sprayed coolants have been found to improve initial cooling in extensive burns, suggesting that water spray combined with fan use may enhance cooling and pain relief. ^{1 2 3 8 9}

Are You a Good Fit for This Trial?

This trial is for individuals who have survived burns covering at least 20% of their body and are now well-healed. They will participate in exercise under heated conditions to test cooling methods. Non-burned individuals can also join for comparison.

Inclusion Criteria

I am a healthy adult between 18 and 65 with no medical conditions.

I am a healthy adult aged 18-65 with burns covering 20% of my body, half of which were severe enough to need skin grafts, and I was hospitalized for at least 15 days.

Exclusion Criteria

Burn Survivors: Any burn-related injuries resulting in at least one night of hospitalization, heart disease or any other chronic medical condition requiring regular medical therapy including cancer, diabetes, and hypertension, abnormalities detected on routine screening, individuals who participate in a structured aerobic exercise training program at moderate to high intensities, current smokers, as well as individuals who regularly smoked within the past 3 years, body mass index of greater than 30 kg/m^2, pregnant individuals, extensive unhealed injured skin

Non-Burned Individuals: Any burn-related injuries resulting in at least one night of hospitalization, heart disease or any other chronic medical condition requiring regular medical therapy including cancer, diabetes, and hypertension, abnormalities detected on routine screening, individuals who participate in a structured aerobic exercise training program at moderate to high intensities, current smokers, as well as individuals who regularly smoked within the past 3 years, body mass index of greater than 30 kg/m^2, pregnant individuals

What Are the Treatments Tested in This Trial?

Interventions

• Water Spray and Fan

Trial Overview The study aims to see if using a fan and water spray can prevent overheating and reduce heart stress during exercise in a hot environment, compared to no cooling. It's a randomized crossover design, meaning all participants will try both methods.

How Is the Trial Designed?

Group I: Non-Burned Individuals Experimental Treatment 2 Interventions

Non-burned individuals will exercise for 60 minutes in the heat while being exposed to either no cooling or cooling via skin wetting (two trials).

Group II: Burn Survivors (20% or more Burn Surface Area burn-injured) Experimental Treatment 2 Interventions

Burn survivors with 20% or more BSA (burn surface area) burn-injured will exercise for 60 in the heat while being exposed to either no cooling or cooling via skin wetting (two trials).

In a study involving 120 rats with burn wounds, it was found that higher temperatures and lower moisture levels increased the rate of water evaporation, which could impact wound healing.

Treatment methods like escharectomy, skin grafting, and the use of film-forming agents were effective in reducing water evaporation from burn wounds, while Azone increased skin permeability and accelerated evaporation.

In a study involving 96 burn patients, tap water was found to be the most effective method for cooling burn wounds, significantly reducing skin surface temperature more than Burnshield® and Burn Cool Spray®.

All three cooling methods effectively reduced pain levels, but tap water and Burn Cool Spray® were more effective than Burnshield®, with the effectiveness of tap water being influenced by its temperature and the timing of treatment after the burn occurred.

In a study involving 10 piglets with induced partial-thickness scald burns, cool running water applied for 20 minutes was found to be the most effective first aid treatment, leading to consistent improvement in wound recovery over 9 days.

In contrast, the use of wet towels and water spray showed variable results, while the control group without treatment experienced worsening of the burn, highlighting the importance of using cool running water for burn first aid.

In a pilot study with 53 healthy participants, spraying 1 liter of coolant was found to cool the skin more effectively and uniformly than pouring 5 liters of water over burns, especially in the first 9 minutes.

Neither method caused hypothermia, indicating that spraying coolant is a safe and efficient technique for the initial management of extensive burns.

In a study of 4537 children with thermal burn injuries, 71.9% received adequate first aid, defined as 20 minutes of cool running water within 3 hours of the injury, highlighting a significant gap in initial treatment practices.

Only a small percentage of paramedics (25.0%) and general practitioners (24.2%) provided adequate cooling, indicating a need for better education and adherence to guidelines among healthcare professionals in managing pediatric burn injuries.

A pre-cooling method using a 5 °C water spray for 30 seconds can significantly reduce the risk of severe skin injury during brief flame exposure, as demonstrated by a TV host's experience with light burns after a 0.74-second exposure to flames.

The study highlights that even minor changes in conditions, such as higher water temperature or longer flame exposure, can drastically increase the risk of severe burns, emphasizing the dangers of high heat flux levels.

Patients with severe burns initially have cooler wound temperatures compared to intact skin, but these wounds warm up to skin temperature within three days post-injury, which is important for recovery.

Fluid evaporation from burn wounds significantly increases heat loss, and patients with larger burns sweat less, indicating that temperature management in their environment is crucial for preventing excessive heat loss.

Using a commercially available cooling blanket for 30 minutes does not lower core body temperatures in healthy adults, indicating it is safe and does not cause hypothermia.

The cooling blanket effectively reduces water evaporation from containers, suggesting it may help maintain moisture in burn treatment scenarios.

In a study using a phantom model to simulate burned tissue, it was found that humidity and air velocity significantly influence the evaporation rate from the skin, which is crucial for managing heat loss in burn patients.

Using infrared radiation can effectively reduce the internal energy needed to maintain skin temperature, allowing for better thermal management and comfort for patients while compensating for heat lost through evaporation.
