12 burns risk factors Flashcards
Risk Factors
§ Substance abuse (eg: alcohol and smoking) § Local cultural practices § Socioeconomic status (eg: open fires, poor heating and lighting, frostbite) § Gender inequality (eg: sulphuric acid thrown on women) § Suspected non accidental injury through violence and neglect (eg: child abuse)
High Risk mechanism of injury
§ Confined space § Electrical injury § Chemical burn/Flash burn § Lightening strike § Concomittant trauma
Adult burns: where do they happen
▪ 62% house
▪ 21% work
▪ 6% automobile/bike
▪ 11% other
Mandatory Referral to Burn Centre
• 5% TBSA in children • TBSA > 10 % • Full Thickness > 5% TBSA • Hands, feet, face, perineum, genitals or major joints • Respiratory burns • Significant pre-existing disease • Circumferential burns • Burns at the extremes of age • Electrical burns • Chemical burns • Burns w/ associated trauma
Type of Burn Injury
§ Thermal:
▪ Electrical:
▪ Chemical:
▪ Radiation:
§ Thermal Burn Injury
flames, steam, hot metal, hot water or liquid
▪ Electrical: Burn Injury
high or low voltage injury, lightning
Chemical Burn Injury
acid, alkali, organic compounds
Burn Injury Radiation:
UV light (sun or artificial), radioisotopes through radiation devices (therapeutic/cancer treatment, industrial or detonation of nuclear device)
A burn injury influences all of the five major functions
of the skin:
Thermoregulation • Fluid and electrolyte imbalance • Immune response • Protection from bacterial invasion • Neurosensory interface
Effects of major burn injury
▪ Fluid and electrolyte shifts ▪ Cardiovascular effects ▪ Pulmonary injury – Upper airway – Inhalation below the glottis – Carbon monoxide poisoning – Restrictive defects ▪ Renal and GI alterations ▪ Immunological alterations ▪ Effect upon thermoregulation
Physiological changes burn injury
▪ Burns less than 25% TBSA produce primarily a local response
▪ Burns more than 25% may produce a local and systemic
response, and are considered major burns
▪ Systemic response includes release of cytokines and other
mediators into systemic circulation
▪ Fluid shifts and shock result in tissue hypoperfusion and organ
hypofunction
Goals related to burns
▪ Prevention
▪ Institution of lifesaving measures for the
severely burned person
▪ Prevention of disability and disfigurement
through early specialised and individualised
care
▪ Rehabilitation through reconstructive surgery
and rehabilitation programs
First Aid burns
▪ Primary survey
▪ Stop the burning process - Charred clothing or
clothing soaked in scalding liquid retains heat \
remove all clothing and all jewellery.
▪ Cool the burn wound- ideally under clean, cool
running water for 20-minutes. Be mindful of
hypothermia, particularly in children.
▪ Proceed to secondary survey
