Initiаl pоst оn Types оf Burn Injuries Pаthophysiology Februаry 10, 2026 Types of Burn Injury  Burn trauma may be obtained by various mechanisms of injury and are characterized by the means of which they are acquired. The main four ways in which burns are manifested are thermal, chemical, electrical, and radiation. The etiology of each type of burn is how healthcare providers are able to define a prognosis along with the classification of the burn. The extent of the burn is determined by the percent of body surface area (BSA), skin thickness, heat level, and contact duration (Capriotti, 2024). Thermal Burns Burns acquired from high heat sources, like fire, scalding liquids or steams, or contact burns are classified as thermal burns. These burns vary depending on the type of duration and depth of exposure and can range from epidermal to subdermal to subcutaneous and deeper. Scald burns are the most prevalent burn in children and are caused by contact with hot, scalding fluids or steam. When these substances are at 158 degrees or higher tissue necrosis occurs within mere seconds. Once exposed to this type of burn, the damage has already occurred and must be treated. In order to treat thermal burns, several steps must ensue. The heat source must be removed, the patient should be stabilized, the individual’s body temperature should be maintained, injury classification should be identified, and the patient should be prepared to be transported. The airway must be assessed and if the airway is not exhibiting eupnea, intubation may be required. If the patient is showing normal respiration, oxygen should be given via face mask and the head should be elevated. The patient should not be given fluids via mouth because of the possibility of aspiration or emesis. Fluids should be given to the patient through an intravenous line in a non-burned area. In cases of highly burned TBSA, the patient may need to undergo fluid resuscitation, preventing hypovolemic shock. Vital signs should be monitored to actively monitor fluid resuscitation and assess circulation.  Chemical Burns Unlike thermal burns, chemical burns are much more infrequent. Industrial workers are the most likely victims of these burns, often ingesting pernicious chemicals. Chemical burns may cause proteolysis, or protein breakdown, and creates the skin of a burn victim to be gray. These types of burns will remain causing damage to the patient until the causative agent of the burn is removed. The chemical agent is removed by firstly removing any clothing that may be harboring the chemical, then if the agent is dry, brushing it off, and flooding the wound with water for 20 minutes. If a patient has been burned with a chemical that requires specialized treatment, calling the Poison Control Center may be necessary for proper treatment.  Electrical Burns Similar to chemical burns, electrical burns account for less than 10% of all burns acquired (Capriotti, 2024). Risk factors for this type of burn include young adult men employed in electrical job positions, often low-income (Chen and Wang, 2024). Electric currents typically create an entry and exit wound on the victim, often damaging internal organs as the current moves through the body. Because of this, it is important that the patient is assessed for internal damage, the current often takes the path of least obstruction in the body. The entry and exit injuries may give important information on the path of the current and provide answers to which of the organs may be harmed. If the patient’s vital organs were damaged, the extent of trauma will be more severe and mortality is more likely. The extent of the trauma is dependent upon the duration of injury, pathway of the electrical current, and amount of voltage. The treatment of electrical burns begins with ensuring that the current no longer remains. Assessing the patient for consciousness sets the provider up to then ensure that the patient is immobilized with a cervical collar to prevent further spinal injuries.  Radiation Burns Radiation burns are distinct because they are acquired by ionizing radiation material. These burns are harmful from thermal burns and also internal and external contamination. External burns from radiation typically affect skin and tissue, and damage may be visibly delayed and appear weeks after the initial exposure. Asking the patient for their remembrance of the event is helpful in understanding the extent of exposure to radioactive materials. Radiation burns are measured in “rads,” or the radiation amount absorbed by tissues. However, the risk of the exposure is measured in “rems.” A patient’s cutaneous radiation injury (CRI) is diagnosed by the amount of radiation, depth of the current, and visible harm obtained. Internal radiation exposure may cause acute radiation syndrome (ARS) if the patient is exposed to extreme amounts of radiation in a short time frame. Damage to the central nervous system and gastrointestinal issues are common in those exposed to extreme levels of radiation. Irrigation of external wounds helps to decrease internal damage. If more information must be received by the providers, the Radiation Emergency Assistive Center may be contacted.  Burn Classifications All burns may be classified under three categories: superficial, partial-thickness, and full-thickness. Superficial burns, previously known as first-degree burns, harm only the epidermis. Sunburns and brief exposure to hot substances are common to this type of burn. With superficial burns skin remains intact, typically are painful, and blistering does not occur. Defining the burned BSA percentage is not necessary since the skin is typically healed within a week. The next degree of burns is partial thickness, formerly named second-degree burns. Depending on the measure of tissue necrosis, partial-thickness burns may be superficial or deep. Superficial partial-thickness wounds burn the epidermis and show epidermal blisters, edema, and wet, raw, pink or red skin. These burns may heal within 3-6 weeks, sometimes with skin discoloration. Deep partial-thickness burns affect the epidermis, and reticular layers of the dermis. The skin color is often similar to that of superficial partial-thickness burns, but can appear blotchier. The patient’s pain may vary from much to little depending on the amount of nerve tissue affected. Blisters are common to this burn, and should remain intact in order to prevent infection. The final classification of burns are full-thickness burns. These burns damage the epidermis, dermis, follicles, and all underlying tissue. Most patients experience no pain because of extensive nerve damage obtained. The skin appears red, black, white, or brown and has considerable edema. These burns are often caused by prolonged exposure and are the most severe burn obtained.  Conclusion In summary, burns are categorized by thermal, chemical, electrical, and radiation. Each type of burn is acquired differently and must be treated likewise. Thermal burns can be recalled as burns acquired from hot liquids or steam. Chemical burns are often from strong acid materials, like household cleaning products. Electrical burns vary from low-voltage household currents to high-voltage from a lightning strike. Radiation burns are acquired from ionizing radioactive material. Finally, each type of burn may range from superficial to partial-thickness to full-thickness and treatment for each burn is extremely varied and should be determined using this classification system.         References: Capriotti, T.
