Burns and EBM
There is no MetaanalysisThere is one Randomised trial (it showed more deaths in the trial group)There are precious few case controlled trials (all from >25 years ago)There are lots of case reports/audits/ideas/suggestions

Types of Burn Injury
Thermal–Scalds –Flame– Contact– Cold
Electrical
Chemical
Radiation
‘Medical’ Skin loss e.g. Toxic Epidermal Necrolysis

Incidence of Burn Injuries100 severe burns requiring resuscitation per year – half of these are children20 - 30 deaths/year in Australia50% firstly admitted to non-specialist units Incidence falling Prognosis improving

Waiting for EmmaI was sitting in my usual restaurant when my attention was drawn by the hizz and steam as a plate of sizzling oriental steak was paraded aloft with style towards a young couple dining alone. As the waiter reached the table, he tripped or faltered and the entire contents of the plate fell onto the young womans chest.

Waiting for EmmaShe screamed in agony and as my hand flew to cover my mouth in horror, I observed a man sitting 2 tables away from her immediately arise, stride to her table, picking up a bottle of Moet from the table in between

Waiting for Emma
and pulling her blouse away from her chest, he proceeded to empty the champagne onto her ample clevage with immediate relief on her part.

What is an inhalation injury?
Damage caused by aspiration of superheated gases, steam, hot liquids or noxious products of combustion Damage may be to upper or lower airway or bothIf the event was associated with an explosion, there may also be “blast” injury to the lungs

Case Report
It was a dark and stormy night45 year old man, had new shiny BBQ on new shiny deck.20+ for dinner and numerous beers“decided” to move the BBQ under cover, due to rain, so disconected from mains gas and connected to bottled.difficult to start - followed by bang.

Primary Survey B - Breathing
Breathing and control of ventilationRemember usual trauma causes of breathing problems, pneumothorax, haemothorax etcThink about Blast vs Burnt lungExclude circumferential burn to chest

Primary Survey C - Circulation
Stop the BleedingAssess Circulation BP, P, peripheral perfusionHypovolaemic shock at early stage will not be due to burn - suspect traumaLarge bore IV access through unburnt skin and not distal to large burnsSecure lines well

Mumford’s Rule of Tape
In a retrieval the amount of tape and ties used to hold in lines and tubes
shall not exceed the distance between the patient and the receiving hospital,
but anything less than that is acceptable
![Page 47: Burns - Resuscitation, Referral and Retrieval](https://reader036.fdocuments.in/reader036/viewer/2022062410/56815535550346895dc30d72/html5/thumbnails/47.jpg)
Harrison’s Corollary
In a retrieval no matter how you secure the ETT, when you arrive at the
receiving ICU, it will be wrong
So follow Mumford’s rule
![Page 48: Burns - Resuscitation, Referral and Retrieval](https://reader036.fdocuments.in/reader036/viewer/2022062410/56815535550346895dc30d72/html5/thumbnails/48.jpg)

Black Saturday: the immediate impact of the February 2009 bushfires in Victoria, Australia. Med J Aust. 2009 Jul 6;191(1):11-6.

Abstract
There were 414 patients who presented to hospital EDs as a result of the bushfires. Patients were triaged at the emergency scene, at treatment centres and in hospital. National and statewide burns disaster plans were activated. Twenty-two patients with burns presented to the state's burns referral centres, of whom 18 were adults. There were a further 390 bushfire-related ED presentations. Most patients with serious burns were triaged to and managed at burns referral centres.
CONCLUSIONS:
Most bushfire victims either died, or survived with minor injuries. As a result of good prehospital triage and planning, the small number of patients with serious burns did not overload the acute health care system
