    This video demonstrates the assessment and management of burns, using equipment that is recommended within the locality at the time of production. Remember to check your local, current guidelines before putting anything into practice. Produced by HCPs and students.

    This video demonstrates use of burn gel wraps, which may no longer be used in your ambulance Trust. Please check your local guidelines regarding this. According to the British Burn Association:

    Burn gel wraps may be used to provide analgesia, but only after adequate cooling has
    occurred as they do not actively remove heat from the wound

    Varley et al (2014)

    BURNS: The practical stuff

    This video contains content some might find sensitive.

    Treatment

    With all assessments and interventions, use an aseptic technique, especially because ‘burns are prone to infection’

    Purcell, 2003: 217

    Airway

    The patient’s airway might worsen. Here’s why:

    ‘A burned patient may have a patent airway on the initial evaluation. […] In the time that follows, the face, as well as the airway, will likely swell.’

    NAEMT, 2016: 411

    … So, consider HEMS for RSI.

    Breathing

    The patient’s breathing might worsen. Here’s why:

    Is there a chest wall burn?

    ‘Burns constrict the chest wall similarly to having several leather belts progressively tightening around the patient’s chest. As time progresses, the patient cannot move the chest wall to breathe.’

    NAEMT, 2016: 412

    So, consider HEMS and ventilatory support where needed.

    Other considerations:

    Inhaled toxins ‘can produce asphyxiation’

    NAEMT, 2016: 412

    If:
    – LOC in a fire with ‘heavy smoke’
    – trapped patient in a fire
    consider O2

    El-Helbawy & Ghareeb, 2011

    Circulation

    Swelling might get worse. Here’s what to do about it:

    ‘Distal limb perfusion may be critically reduced’; ‘Burned extremities should be elevated during transport to reduce the degree of swelling in the affected limb’

    NAEMT, 2016: 412

    A complication of swelling:

    Fluid loss occurs from swelling and evaporation

    NAEMT, 2016: 416

    Giving Fluids – Pros and Cons

    Consider IV fluids, especially if the burn is >10% of the body (AACE, 2016: 265-266). Keep watching for info on how to determine this.

    Give fluids with caution. Too much -> ‘cardiac failure, […] infectious complications, acute respiratory distress syndrome, and even death’.

    Too little -> ‘hypovolemic shock, organ failure’

    (NICE, 2016)

    Judicious fluid management of children with severe burn injury can improve the respiratory outcome measures of these children

    Duran and Sheridan, 2016

    Cannulating – Essentials

    When cannulating, ‘placement through the burn is appropriate [only] if no alternative sites are available’

    NAEMT, 2016: 412

    What about heat?

    Patients with burns are not able to maintain their own body heat

    NAEMT, 2016: 413

    …So, give blankets

    ECGs

    ECGs are required for electrical burns (AACE, 2016: 265) but consider them for all burns as ‘cardiac dysrhythmias’ result from the release of ‘muscle potassium’ (NAEMT, 2016: 418) and studies have shown disturbances in the cardiac functions of in-hospital burn patients (Jeschke et al, 2008).

    Disability

    Do your BMs

    Hyperglycemia may occur in burns patients and has a higher risk of ‘morbidity and mortality in critically ill patients’ (Wolfe et al, 1979; Mecott et al, 2010).

    Pain management in children

    In children, ‘a multi-modal approach to pain and sedation can improve the neurological status of severely burned children’

    Duran and Sheridan, 2016

    Expose/Examine

    Cooling the burn:

    Cool with a wet compress

    Purcell, 2003: 217

    ‘Cooling gels such as Burnshield are often used by paramedics. These are useful in cooling the burn and relieving pain in the initial stages.’ *

    Be aware of the risk of ‘heat loss’

    Hudspith and Rayatt, 2004

    *This guidance is changing. Check your local guidance first, and consider the use of cling-film after running water.

    Documentation during examination:

    Assess and document:

    ‘Burn depth & features’ (Purcell, 2003: 217)

    Other considerations:

    Anticipate Swelling. Take off jewelry. Be aware that these and clothing ‘retain residual heat’ (NAEMT, 2016: 413).

    Cooling – more details

    Irrigate early to cool and prevent further burning.

    Chemical burns: 15 mins min (AACE, 2016: 265)

    All burns: Max 20 mins (AACE, 2016: 266)

    This is most effective ‘within 20 minutes of the injury’ (Hudspith and Rayatt, 2004).

    Don’t use ice cold water as ‘intense vasoconstriction can cause burn progression’ (Hudspith and Rayatt, 2004).

    When using cling film

    Discard ‘the first few centimetres’ to be aseptic

    ‘lay this on the wound rather than wrapping the burn’ to anticipate swelling

    (Hudspith and Rayatt, 2004)

    Consider using wet dressings instead in chemical burns (Allison and Porter, 2004)

    Estimating total burns

    Consider the use of tools to estimate the total body percentage of the burns (NICE, 2016; Mersey Burns, 2013).

    Transport

    Using those tools [such as Mersey Burns] will help determine the right treatment centre for the patient and the treatment priority.

    Time critical features:

    • major abcd problems
    • airway burns
    • history of hot air or gas inhalation
    • respiratory distress
    • burns that completely encircle the chest, neck, or limb
    • significant facial burns
    • burns >10% total body area
    • ‘presence of other major injuries’

  • Should Patients Take Caffeine-Containing Analgesics?

    Should Patients Take Caffeine-Containing Analgesics?

    Many of our patients have high temperatures, especially during COVID outbreaks. Some of them are taking over the counter pain relief as required. This is of course recommended, however many of our patients are also tachycardic due at least in part to their high temperatures. When they complain of palpitations, do they need to be aware of the effects of caffeine-paracetamol combinations? Should they be taking this combination at all, or should they simply ease off dietary sources of caffeine while taking analgesics? Here are a few quotes on the subject for discussion. Full references are below. For a fast fact summary, have a look at the featured image below:

    A dose of caffeine equivalent to a mug of coffee added to a standard dose of common analgesics such as paracetamol or ibuprofen provided better pain relief. Analgesic plus caffeine increased the number of people who had a good level of pain relief by 5% to 10% compared with analgesic alone

    Derry et al, 2014.

    But…

    When the recommended paracetamol-caffeine dosing regimen is combined with dietary caffeine intake, the resulting higher dose of caffeine may increase the potential for caffeine-related adverse effects such as insomnia, restlessness, anxiety, irritability, headaches, gastrointestinal disturbances and palpitations.

    EMC, 2017

    Even a small dose of 50 mg caffeine can cause tachycardia, anxiety and ectopic beats. Toxicity is normally seen at doses > 500 mg, but this depends on tolerance.

    Take into account dietary and other medicinal sources of caffeine: people may not be aware from the brand name that a particular preparation contains caffeine. Consider whether paracetamol with caffeine is necessary: it cannot be assumed that it will be tolerated in the same way as paracetamol alone.

    You must read the full disclaimer at www.article999.co.uk/about/ (disclaimer tab) before putting into place anything you see here. Useful information is available in the text on this video, so if you only listen to the narration you will miss important facts. The ventilation settings mentioned in this video are what is recommended by Smiths Medical, current guidelines and some articles – however, as with all topics, there is always varying information available online & alternative expert advice, and no video can cater for all of that. Similarly, this video is intended to demonstrate how to use equipment & to introduce or remind you to the Why, What and When of ventilators – not to tell you that you should or shouldn’t be using it. That is dependent on local guidelines, your research & your choice as a clinician. This video merely highlights the varying advice regarding tidal volume settings, and in the text points out the potential problems with some of the figures. No specific volume is recommended.

    Article 999. Ventilators: Why, What, How, When?

    This video has been made by UK Paramedics following guidelines. It is not endorsed by any author, organisation or Ambulance Trust. You must read the full disclaimer at www.article999.co.uk/about/ and refer to your local guidelines before putting into place anything you see here. This video is intended to demonstrate how to use the ventilator according to use guides and guidelines – not to tell you that you should or shouldn’t use it. That decision is up to you and should be dependent on local guidelines and your own research. This is what the textbooks, the manufacturer and a few articles say & is not intended to represent the expert opinions or experience of others within healthcare.

    Remember hand hygiene, bare below the elbows and gloves in real life.

     

     

    How?

    1. To remove the ventilator from the racks, pull the flap to the side and push the ventilator up. To put it back in, simply push it down and pull the flap to the side again.
    2. To connect to the gas supply, push the hose into the socket and twist. It’s the same when connecting to a portable oxygen cylinder.
    3. When you turn it on, the ventilator should complete a self check. The alarm lights should flash in sequence, there should be one burst of the high pressure audible alarm, and the orange indicator should flash for 60 seconds.
    4. Next, check the indicator shows white for O2.
    5. Connect the patient circuit [shown in video].
    6. Next on the list, adjust the ventilation parameters. Set the air mix control to no air mix for respiratory arrest or CPR. Set the relief pressure control to 40. Set the respiratory rate to 12. As for the tidal volume, it varies massively as you can see on the screen. It depends on whether you opt for an average value or base it on the patient’s weight. Smiths Medical (2017) advise 800-900ml on their training video, [but this may not be advisable] but don’t worry too much about the slight differences in tidal volume because the PneuPac features a high pressure alarm that we’ll discuss shortly. The alarm will help you identify if the tidal volume is too high for your patient.

    (Gregory & Mursell, 2010: 44; Pilbery & Lethbridge, 2016: 189; Baker, 2012; Smiths Medical, 2017)

    The following demonstrate the variance in researched texts and guidelines – not necessarily the advised settings:

    400-600ml Baskett, 1996
    500-600ml Perkins et al, 2015
    600ml Baker, 2016
    800-900ml Smiths Medical, 2017 – may not be advisable due to risks of barotrauma. See below
    6-8ml/kg Bocklage & Balk, 2017; Frakes, 2007
    10ml/kg or 5-8ml/kg Baker, 2012 – depending on the extent of the risk of barotrauma

    7. Next, temporarily occlude the patient connection. The relief pressure monitor should go to the maximum setting – i.e. 40cmh20.

    (Gregory & Mursell, 2010: 44; Pilbery & Lethbridge, 2016: 189; Baker, 2012; Smiths Medical, 2017)

     

    What do the audible warnings mean?

    • Top left is the high pressure alarm
    • Top right is low pressure
    • Bottom left is the battery indicator
    • The middle one tells you when breathing is detected by the ventilator

    (Smiths Medical, 2017)

    High pressure = excessive tidal volume, incorrect airway position, kinked ET tube, or incorrect ventilation settings.
    If the pressure is reaching it’s max, there may be something wrong with the circuit.

    If you’ve checked the above and the alarm is still sounding, Smiths Medical (2017) advise that your tidal volume setting might simply be too high.

    Low pressure = leakage or insufficient tidal volume/settings, faulty valve in the patient’s circuit
    This alarm tends to occur when pressure drops below 10cmh20

    Earlier, I pointed out the alarm in the middle, at the bottom. This is SMMV. It’s an indicator that will flash green if the patient is breathing for themselves. The ventilator will assist if the patient breathes with less than 150ml of tidal volume. Between 150-400ml the ventilator will extent the exhalation time to allow the patient to complete their own breath, and above 400ml the ventilator will allow the patient to breathe and will not assist, but may still assist on the next breath if required (Smiths Medical, 2017; Baker, 2012).

     

    Extra facts:

    McCarty et al (2012) found that ‘ventilation rates and tidal volumes commonly exceeded Guideline recommendations. This resulted in […] excessive mean airway pressure’

    Smiths Medical (2017) advise that peak inflation pressure should be below 20cmh20 when using a mask to ventilate due to the issues of too high pressure

    Inspiration to Expiration should be 1:2 (Smiths Medical, 2017; Baker, 2012)
