Burns – the latest guidance for treating a burn

by Emma Hammett | Jun 3, 2019 | Uncategorized | 0 comments

Burns are extremely common, painful and potentially life-changing injuries. Burns frequently become infected and scarring from burns is often disfiguring and permanent.In fact, 13,000 burns injuries are treated in British hospitals each year. 200 people die from burns related injuries each year.

Here we will explain what the new guidance is and why it works.

1. A third of adult burns are work-related. Thus, those working in fields where one is exposed to flames, steam, hot objects or chemicals should make sure they are taking all the safety precautions advised. If you are unsure about first aid and the law, consider reading our free ebook https://firstaidforlife.org.uk/first-aid-and-the-law-a-guide-for-smes-free-ebook/.
2. 70% of all paediatric burn’s incidents occur in children under 4 years old. Children’s skin is more sensitive and thinner than an adults and a small child can still receive serious burns from a cup of tea that has been made for more than 10 minutes. It is vital that children are protected from heat sources and additional measures taken to reduce the risk of burns.
3. 10% of burns are in elderly patients and the mortality rate is significantly higher for these cases. As with small children, older people’s skin becomes thinner and more friable. Their reflexes are often slower to pull away from a source of heat and often their nerve endings are less sensitive to the dangers too. With failing sight and balance and a desperate wish to remain independent, they are particularly vulnerable to the risk of burns.

Who’s most at risk?

What’s new?

First Aid Burns treatment has previously been to hold the affected area under cool running water for at least ten minutes. This has changed, as of May 2019, the latest advice from the Australian research team at their national Centre for Children’s Burns – now adopted by the NHS, British Burn Association and more – is to extend the time that the burn should be treated to a full 20 minutes under cool running water.

The previous recommendations were based upon conflicting published studies and an unproven idea of best practice.

However, recently burn researchers in Australia have reviewed published studies and undertaken further work to identify the latest advice for optimal burns treatment.

In brief:

1. Use cool running water of 2-15 degrees in Celsius.
2. Treatment should last a full 20 minutes.
3. Ice should not be applied to a burn.
4. Ice-cold water should not be applied to a burn as this can lead to hypothermia.

The research supports that effective treatment of burns (i.e. following the steps given above) will significantly reduce tissue damage, hasten wound re-epithelialisation and reduce scarring.

Problem with past research papers?

Rats and pigs

Interestingly, research done in the past has had conflicting results and this is partly due to the types of animal used to conduct testing. Many studies chose rodents as their models, as rats and mice are easily available in laboratories and comparatively cheap to experiment with.

However, rodents’ skin heals differently to humans as rather than the human process of wound re-epithelialisation (skin cell rebuilding), rodent wounds heal via contraction.

Time issues

Studies have often been short-term – so they have failed to consider long-term scar formation. Current patients are often highly concerned about scar visibility.

What are the benefits of cool running water?

Clinical studies have indicated a whole range of benefits including:

1. Decreased wound depth.
2. Reduced time for wound re-epithelialisation.
3. Decreased hospital stay/visits
4. Decreased requirement for grafting and scar management

Essentially, water itself is responsible for reducing scar tissue.

Why running water?

It is not clear yet whether the treatment is more effective under running water, or whether the use of a large quantity of continually-refreshed water which is beneficial. So, it is possible that immersion in cool water would have the same beneficial effect. However, immersion in a bowl or sink will warm over time.

Practically, it is normally easiest to place the burned area under cool running water such as a tap.

Wet towels (refreshed every three minutes) and water spray have been shown to be less effective.

Additionally, the water should preferably be drinkable, to reduce risk of wound infection. This means if you are in a country with non-drinkable tap water, use bottled water instead.

What’s the problem with ice?

If the water must be cool, why not apply ice to the burned area?

Although ice water may be more beneficial for wound outcome (including re-epithelialisation and cosmetic appearance), it has frequently led to cases of serious and potentially fatal hypothermia, particularly with larger surface area burns.

However, it is possible that ice water (2 degrees Celsius that is) could be effective on small burns with minimal risk. However, studies have not yet been conducted on larger animals to test this, so currently cool water remains the recommended temperature for the treatment of burns.

How long is long enough? And how long is too long?

This is another area in which previous research has been conflicting and confusing – as recommended times have ranged from 30 minutes to 3 hours!

Studies have shown that the optimal time to run the burn under cool running water is for a full 20 minutes. After 20 minutes, there does not appear to be any further benefit.

People often continue treating their burn to relieve pain. The advice now is to treat the pain separately if it persists, with paracetamol or other analgesia.

Remove all jewellery and clothing covering the burned area.

What if I can’t treat my burn immediately?

Immediate treatment is recommended to reduce tissue damage and help reduce pain. But there is a lot of controversy about how long after the injury treatment can retain effectiveness.

Recently, studies have shown that even if treatment is delayed for between 1 or 3 hours, running the burn under cool running water is still beneficial, improving wound re-epithelialisation and decreasing the amount of scar tissue.

Should I use hydrogels such as BurnShield, Burnfree and Water-Jel?

In fact, 37% of UK fire departments use water gels instead of cool running water. However, 76% use them in addition to cool running water. There have been limited studies with hydrogels, however studies have indicated that these gels may not offer additional healing benefits.

The problem with such gels are threefold:

1. They must be applied for an hour
2. Risks of hypothermia are increased in large burns
3. Viscous liquid from the gel can interfere with the burn.

They may be useful in areas or situations where it is not possible to treat the burn under cool running water.

Is using Aloe vera effective?

Whilst studies have yet to confirm whether Aloe vera could be effective in treating superficial burns and providing pain relief, it has been shown to have no beneficial effect on deeper burns. Therefore, it is not recommended as a treatment.

Therefore, to recap, the advice is:

Cool running water over the affected area for a full 20 minutes. The running water should be tap temperature i.e. between 2 and 15 degrees Celsius. 12 degrees is optimal. The treatment should be conducted as quickly as possible (ideally within 10 minutes).

After first aid

Having taken the recommended precautions, you’ll need to decide whether to go to hospital and receive further treatment.

Monitor for signs of hypothermia and try to keep the casualty warm whilst cooling the burn.

Seek medical attention if:

1. The casualty is a baby or child.
2. The burn is larger than a 50p coin.
3. A burn (of any size) has resulted in white or charred skin.
4. Burns are located on the face, perineum, feet or hands.
5. The burn is blistered.
6. Burns are caused by chemicals or electricity.

You should also seek medical help immediately if the affected person:

1. Has other injuries.
2. Is showing signs of shock (rapid breathing, weakness and dizziness, cold, clammy skin or sweating).
3. Is pregnant.
4. Is aged over 60 or under 5.
5. Has a medical condition (heart, lung, liver disease or diabetes)
6. Has a weakened immune system – such as AIDS or is undertaking chemotherapy.

If the casualty has been involved in a fire-symptoms of smoke inhalation include:

1. Coughing
2. Sore throat
3. Difficulty breathing
4. Singed nasal hair
5. Facial burns
6. Rasping voice

These symptoms may be delayed and could indicate damage to the airway, which is extremely serious. Remove the casualty from danger, treat any obvious burns and seek medical attention immediately

Research used came from two papers:

1. ‘First aid treatment of burn injuries’ – Cuttle and Kimble, 2019 https://www.researchgate.net/publication/43528338_First_aid_treatment_of_burn_injuries
2. ‘Management of Burns in Pre-Hospital Trauma Care’ – Battaloglu, Leon-Villapalos, Young & Porter for the British burn Association
