Touch sensation is impaired. Show Lack of blanching with pressure is observed. Wounds appear waxy white, dark brown, or charred Touch sensation is impaired due to impaired nerve endings in full-thickness burns. Lack of blanching with pressure is observed, because all skin elements are destroyed. Wounds appear waxy white, dark brown, or charred in full-thickness burns, because all skin elements and local nerve endings are destroyed, and coagulation necrosis is present. Blanching with pressure is observed in partial-thickness burns, because varying degrees of both the epidermis and dermis are involved, and skin elements of regeneration are viable. Wounds appear mottled white, pink to cherry-red in a partial-thickness burn. p. 434 Recommended textbook solutions

Care of superficial burn Stop burning process with water or saline. Remove smoldering clothing or jewelry. BSI. Continually monitor airway. Prevent further contamination. Cover burned area with a dry sterile dressing. Do not use lotion or antiseptic. Transport. Partial thickness burns Involves epidermis and dermis: does not involve underlying tissue. Intense pain. White to red skin that is moist and mottled. Blisters. Full thickness burns Extends through all dermal layers; may involve subcutaneous layers, muscles, bone, or organs.

Per existing medical conditions. Patients will experience burn shock A form of non hemorrhagic hypovolemic shock resulting from there burn injury. Fourth degree burns
Commonly associated with electrical burns The tough and leathery dead soft tissue formed in the full thickness burn injury is called an eschar. ... A fourth degree burn is a very deep burn that extends through all layers of skin and into the tendons, ligaments, muscles, bone and blood vessels. ... Burns are classified as critical, moderate, or minor. ... Inhalation injuries or burn involving the airway are always critical. ... The most important factors to consider in determining burn severity Depth of burn- Critical burns Full thickness burns to hands, feet, face, or genitalia. Critical burns continued Burns complicated by painful,
swollen, deformed extremity. Moderate burns Full thickness burns of 2-10% body surface area, excluding hands, feet, face, genitalia, & upper airway. Partial thickness burns of 15-30% BSA. Pediatric considerations Relative size... Greater surface are in relationship to total body size. Full thickness / partial thickness burns greater than 20% or involving hands, feet, face, airway, genitalia are considered a critical burn in a child. Pediatric burns Partial thickness burn of 10-20% is a moderate burn in a child.
ALS upgrades are required for Partial to full thickness or chemical burns to face or suspicion of airway involvement. ALS upgrades Partial-full thickness or chemical burns if patient is 5
years or younger. Chemical burns Protect yourself! Electrical burns care Administer oxygen. Monitor patient closely for respiratory and cardiac arrest. Often more severe then external indications. Treat soft tissue injuries associated with burn. Look for entrance and exit wound. Minor burns Full thickness burns involving less than 2% BSA. The rule of nines Is a method for estimating how much body surface area is burned in an adult or infant patient. The rule of nines or other BSA calculations are not applied to superficial burns ... Adult rule of nines The head and neck together, each upper extremity, the chest, the abdomen, the upper back, the lower back, the front and back of each lower extremity each represents a BSA of 9% Infants 1 year or less. The head and neck are 18% the chest and abdomen 18% the entire back as 18% each upper extremity 9% and each lower extremity as 14% Remember that critical burns are not immediately life threatening. Immediate causes of death are airway swelling and inhalation injuries ...

This method divides the body's surface area into percentages. The front and back of the head and neck equal 9% of the body's surface area. The front and back of each arm and hand equal 9% of the body's surface area.
How do you determine the extent of a burn?The extent of the burn injury is expressed as a percentage of the patient's total body surface area (TBSA). Superficial (first-degree) burns are not included in percentage TBSA burn assessment. This estimation can be facilitated using a Lund-Browder chart, the Rule of Nines, or the palm method.
How much do you estimate the extent of burn damage to your patients body surface is?Extent of the Burn
Several methods are available to estimate the percentage of total body surface area burned. Rule of Nines - The head represents 9%, each arm is 9%, the anterior chest and abdomen are 18%, the posterior chest and back are 18%, each leg is 18%, and the perineum is 1%.
