The first hospital to treat burns opened in 1843 in London, England, and the development of modern burn care began in the late 1800s and early 1900s.<ref name=TBCChp1/><ref name=David2012/> During World War I, [[Henry Drysdale Dakin|Henry D. Dakin]] and [[Alexis Carrel]] developed standards for the cleaning and disinfecting of burns and wounds using [[sodium hypochlorite]] solutions, which significantly reduced mortality.<ref name=TBCChp1/> In the 1940s, the importance of early excision and skin grafting was acknowledged, and around the same time, fluid resuscitation and formulas to guide it were developed.<ref name=TBCChp1/> In the 1970s, researchers demonstrated the significance of the hypermetabolic state that follows large burns.<ref name=TBCChp1/>

The "Evans formula", described in 1952, was the first burn [[resuscitation]] formula based on body weight and surface area (BSA) damaged. The first 24 hours of treatment entails 1ml/kg/% BSA of crystalloids plus 1 ml/kg/% BSA colloids plus 2000ml glucose in water, and in the next 24 hours, crystalloids at 0.5 ml/kg/% BSA, colloids at 0.5 ml/kg/% BSA, and the same amount of glucose in water.<ref>{{cite journal | title=The Evans Formula Revisited| journal=Journal of Trauma and Acute Care Surgery| volume=12| issue=6| pages=453–8| date=June 1972| last1=Hutcher| first1=Neil| last2=Haynes| first2=B.

==Signs and symptoms==
The characteristics of a burn depend upon its depth. Superficial burns cause pain lasting two or three days, followed by peeling of the skin over the next few days.<ref name=EMP2009/><ref name=TBCChp10/> Individuals with more severe burns may indicate discomfort or complain of feeling pressure rather than pain. Full-thickness burns may be entirely insensitive to light touch or puncture.<ref name=TBCChp10/> While superficial burns are typically red in color, severe burns may be pink, white or black.<ref name=TBCChp10/> Burns around the mouth or singed hair inside the nose may indicate that burns to the airways have occurred, but these findings are not definitive.<ref name=Schw2010/> More worrisome signs include: [[shortness of breath]], hoarseness, and [[stridor]] or [[wheezing]].<ref name=Schw2010/> [[Pruritus|Itchiness]] is common during the healing process, occurring in up to 90% of adults and nearly all children.<ref name=Itchy2009>{{cite journal | vauthors = Goutos I, Dziewulski P, Richardson PM | title = Pruritus in burns: review article | journal = Journal of Burn Care & Research | volume = 30 | issue = 2 | pages = 221–8 | date = Mar–Apr 2009 | pmid = 19165110 | doi = 10.1097/BCR.0b013e318198a2fa | s2cid = 3679902 }}</ref> Numbness or tingling may persist for a prolonged period of time after an electrical injury.<ref name=RosenChp140/> Burns may also produce emotional and psychological distress.<ref name=Epi2011/>

Disruption of these functions can lead to infection, [[Hypoesthesia|loss of skin sensation]], [[hypothermia]], and [[hypovolemic shock]] via dehydration (i.e. water in the body evaporated away).<ref name=Tint2010/> Disruption of cell membranes causes cells to lose potassium to the spaces outside the cell and to take up water and sodium.<ref name=Tint2010/>

==Diagnosis==
Burns can be classified by depth, mechanism of injury, extent, and associated injuries. The most commonly used classification is based on the depth of injury.

=== Size ===
[[Image:Wallace rule of nines-en.svg|thumb|Burn grade is determined through, among other things, the size of the skin affected. The image shows the makeup of different body parts, to help assess burn size.]]
The size of a burn is measured as a percentage of [[total body surface area]] (TBSA) affected by partial thickness or full thickness burns.<ref name=Tint2010/> First-degree burns that are only red in color and are not blistering are not included in this estimation.<ref name=Tint2010/> Most burns (70%) involve less than 10% of the TBSA.<ref name=TBCChp3/>

There are a number of methods to determine the TBSA, including the [[Wallace rule of nines]], [[Lund and Browder chart]], and estimations based on a person's palm size.<ref name=EMP2009/> The rule of nines is easy to remember but only accurate in people over 16&nbsp;years of age.<ref name=EMP2009/> More accurate estimates can be made using Lund and Browder charts, which take into account the different proportions of body parts in adults and children.<ref name=EMP2009/> The size of a person's handprint (including the palm and fingers) is approximately 1% of their TBSA.<ref name=EMP2009/>

To determine the need for referral to a specialized burn unit, the American Burn Association devised a classification system. Under this system, burns can be classified as major, moderate, and minor. This is assessed based on a number of factors, including total body surface area affected, the involvement of specific anatomical zones, the age of the person, and associated injuries.<ref name=CEM2012/> Minor burns can typically be managed at home, moderate burns are often managed in a hospital, and major burns are managed by a burn center.<ref name=CEM2012>{{cite book| veditors = Mahadevan SV, Garmel GM |title=An introduction to clinical emergency medicine|year=2012|publisher=Cambridge University Press |location=Cambridge|isbn=978-0-521-74776-9|pages=216–219|url=https://books.google.com/books?id=pyAlcOfBhjIC&pg=PA216|edition=2nd|url-status=live|archive-url=https://web.archive.org/web/20160520142151/https://books.google.com/books?id=pyAlcOfBhjIC&pg=PA216|archive-date=20 May 2016}}</ref> Severe  burn  injury  represents  one  of  the  most  devastating forms of trauma.<ref>Barayan D, Vinaik R, Auger C, Knuth CM, Abdullahi A, Jeschke MG.

=== Patient support ===
Burn patients require support and care – both physiological and psychological. Respiratory failure, sepsis, and multi-organ system failure are common in hospitalized burn patients. To prevent hypothermia and maintain normal body temperature, burn patients with over 20% of burn injuries should be kept in an environment with the temperature at or above 30 degree Celsius.<ref>{{cite web|date=2020-09-26|title=Medically Sound: Treating and Caring for Burn, Electricity, and Radiation Victims|url=https://urmedlife.blogspot.com/2020/09/accidentally-scarred-for-life-yet-still.html|access-date=2020-11-01|website=Medically Sound}}</ref>{{better source needed|date=November 2020}}

Metabolism in burn patients proceeds at a higher than normal speed due to the whole-body process and rapid fatty acid substrate cycles, which can be countered with an adequate supply of energy, nutrients, and antioxidants. Enteral feeding a day after resuscitation is required to reduce risk of infection, recovery time, non-infectious complications, hospital stay, long-term damage, and mortality. Controlling blood glucose levels can have an impact on liver function and survival.

Risk of thromboembolism is high and acute respiratory distress syndrome (ARDS) that does not resolve with maximal ventilator use is also a common complication. Scars are long-term after-effects of a burn injury. Psychological support is required to cope with the aftermath of a fire accident, while to prevent scars and long-term damage to the skin and other body structures consulting with burn specialists, preventing infections, consuming nutritious foods, early and aggressive rehabilitation, and using compressive clothing are recommended.

The prognosis is worse in those with larger burns, those who are older, and females.<ref name=Tint2010/> The presence of a [[smoke inhalation]] injury, other significant injuries such as long bone fractures, and serious co-morbidities (e.g. heart disease, diabetes, psychiatric illness, and suicidal intent) also influence prognosis.<ref name=Tint2010/> On average, of those admitted to burn centers in the United States, 4% die,<ref name=TBCChp3/> with the outcome for individuals dependent on the extent of the burn injury. For example, admittees with burn areas less than 10% TBSA had a mortality rate of less than 1%, while admittees with over 90% TBSA had a mortality rate of 85%.<ref name=ABA2012pg10/> In Afghanistan, people with more than 60% TBSA burns rarely survive.<ref name=TBCChp3/> The [[Baux score]] has historically been used to determine prognosis of major burns.

In the developed world, adult males have twice the mortality as females from burns.<!-- <ref name=Epi2011/> --> This is most probably due to their higher risk occupations and greater risk-taking activities.<!-- <ref name=Epi2011/> --> In many countries in the developing world, however, females have twice the risk of males.
