Study Notes

Bomb Blast Patient Assessment

A patient after a bomb blast will show significant injuries.
The patient's condition will often appear worse than it is, especially to untrained eyes immediately after the incident.

Skin Injuries

Skin is the largest organ and important for protecting the body and regulating its temperature.
Skin also senses heat, cold, touch, and pain.
Its layers include the epidermis (outer layer of dead cells), dermis (deeper layer with glands), and subcutaneous layer (below the dermis).
Closed injuries have intact skin and typically include contusions (bruises) and hematomas (blood collections under the skin).
Open injuries have breaks in the skin and include abrasions, lacerations, avulsions, punctures, and amputations.

Soft-Tissue Injuries Overview

Soft tissue injuries often appear worse than they actually are.
Immediately after cleaning, an injury might look less severe.
Closed injuries include contusions and hematomas: resulting from blunt force trauma.
Hematoma is a large collection of blood beneath the skin, caused by the rupture of larger blood vessels.
Crush injuries can cause internal organ rupture and severe internal bleeding.
Open injuries include abrasions (superficial), lacerations (varying depth), avulsions (skin/tissue flaps), penetrations/punctures (caused by sharp objects), and amputations.

Emergency Medical Care for Patients with Soft Tissue Injuries

Immediately administer appropriate procedures for preventing further damage and infection.
Isolate the patient.
Administer appropriate supplemental oxygenation.
Stabilize the patient and control any bleeding.
Clean and dress the wounds correctly.

Burns

Burns can result in severe disability, disfigurement, and fluid loss.
Loss of protective barrier may result in hypothermia and infection.
Emergency care initially focuses on stabilizing vital signs, preventing further injuries, or managing life-threatening conditions.
Burns are classified by depth (superficial, partial thickness, full thickness).
The extent of the burn (in terms of percentage of body surface area [BSA]) must be assessed to determine its severity, along with other patient factors like age and pre-existing conditions.

Burns: Severity

The location of the burn, especially on face/upper airway or hands/feet/genitalia, significantly elevates the severity of the injury.
Younger patients (under 5) and older adults (over 55) are at greater risk following burn injuries.
Critical burns include full-thickness burns involving specific areas (such as hands, feet, face, or genitals), as well as burns associated with respiratory injury and full-thickness burns affecting over 10% of the body.
Moderate Burns include full-thickness burns between 2% and 10% BSA, partial-thickness over 15% to 30% of the BSA and superficial burns over 50% BSA.
Minor burns include full-thickness burns under 2% and partial thickness burns of less than 15% affected BSA.

Emergency Care for Burns

Stop the burning process with water or saline.
Remove smoldering clothing and jewelry.
Administer necessary oxygenation.
Monitor the airway for closure, and prevent contamination.
Cover the burn area.
Do not break blisters.
Transport to specialized care facility as appropriate.

Infant and Child Considerations

Children may have greater surface area to total body size and are susceptible to greater fluid loss as part of the burn injury.
Critical burns include full or partial thickness burns than 20% of the BSA.
Moderate burns in children include partial thickness burns of 10%-20% of the BSA.
Minor burns in children are partial thickness burns less than 10% of the BSA.
Children experience a higher risk for shock, airway problems, or hypothermia.
Additional considerations include the possibility of child abuse.

Chemical Burns

Brush off any chemical powders.
Flush the burn with large amounts of water.
Do not contaminate uninjured areas.

Electrical Burns

Do not attempt to remove a patient from the electrical source unless you are trained to do so.
Monitor airway and administer oxygen as necessary or refer to an expert service.
Treat any soft tissue injuries.
Be aware for entrance and exit wound.

The presentation describes different types of soft tissue injuries, their assessment, and emergency medical care.
