Mouth Disorders

Overview 

A burn is tissue damage produced by heat, chemicals, electricity, sunlight, or radiation. The most common causes of burns include scalds from hot liquids and steam, building fires, and flammable liquids and gases. Burns are classified into three types: - First-degree burns only affect the outside layer of skin; second-degree burns affect both the outer layer and the layer underneath, and third-degree burns affect or destroy the deepest layer of skin and the tissues beneath. Swelling, blistering, scarring, and, in severe cases, shock and even death can result from burns. They can also cause infections because they harm your skin's protective barrier. Antibiotic creams can be used to either prevent or cure infections. 

After a third-degree burn, skin or synthetic grafts are required to cover exposed tissue and induce new skin growth. Burns of the first and second degrees normally heal without the need for grafts. 

Introduction

Every year, millions of burn victims require medical treatment. Burns might be moderate or severe, necessitating hospitalization and even many surgeries. This health information describes burns and how to treat them.

 

The Skin

The skin is the body's outermost layer. It shields us from heat, light, harm, and illness. It also keeps the body temperature stable. The skin is the body's biggest organ, weighing around 6 pounds. It is divided into two layers: the outer epidermis and the inner dermis. The epidermis, or outer layer of skin, is largely made up of squamous cells, which are flat, scale-like cells. Basal cells are spherical cells that sit underneath the squamous cells. Melanocytes are the cells that make up the deepest layer of the epidermis. Melanocytes create melanin, which is responsible for the color of the skin. The inner layer of the skin, the dermis, contains: 

1. Blood.
2. Nerves.
3. lymph vessels.
4. hair follicles.
5. glands.

Sweating is produced by the skin's glands and aids in the regulation of body temperature. They also secrete sebum, an oily material that keeps the skin from drying out. Sweat and sebum enter the skin through microscopic holes known as pores. The skin has a dense network of nerves. This network allows humans to perceive feelings and discomfort. 

Burns

A burn is a piece of tissue that has been destroyed by heat, chemicals, electricity, sunlight, or radioactive radiation. The most frequent types of burns are those produced by scalds, building fires, flammable liquids, and gases. Burns are classified into three levels based on the severity of the damage to the skin and its underlying tissues. First-degree burns only harm the skin's surface layer, known as the epidermis. Second-degree burns cause damage to the epidermis and the dermis, the layer beneath the skin. Third-degree burns cause damage or total destruction of the skin and underlying structures. Third-degree burn victims sometimes require skin transplants. 

Symptoms and Treatment

First and second-degree burns are excruciatingly painful. Because the nerves that produce the pain feeling are damaged in 3rd-degree burns, they are typically not unpleasant. Blood vessels are severely damaged by burns. This form of injury causes fluid to leak from blood vessels, causing swelling and blistering. In extreme situations with substantial burns, fluid loss can result in blood volume depletion, shock, and dangerously low blood pressure. If the fluid is not supplied, death is very likely. To restore fluid and maintain blood pressure, an immediate transfusion of blood or a salt solution may be necessary. 

Burns frequently result in infection owing to damage to the skin's protective barrier. Antibiotic creams or ointments are frequently administered to the skin to prevent and cure the infection. Because there is enough underlying skin tissue to repair the skin, first and second-degree burns can heal without skin transplants over time. Third-degree burns need skin grafts or the use of artificial materials to cover and protect the exposed regions, as well as to stimulate the growth of new skin. Bandages must be changed on a regular basis for all degrees of burns in order to expedite healing and avoid infection. Infections induced by burns can arise everywhere in the body. Septicemia, a blood infection, and pneumonia, a lung infection, may both aggravate serious burns. 

In the United States, such illnesses kill 10,000 individuals each year. Because significant burns frequently increase metabolism, nutritional supplementation is critical for patients to survive the burn. Approximately 50,000 burn cases require hospitalization, with approximately half admitted to a specialist Burn Unit or Intensive Care Unit (ICU).  Adult respiratory distress syndrome, or ARDS, is a condition in which the lungs fail. Patients with severe burns are more likely to develop ARDS, which can be fatal. The burns may cause scarring. Some of these scars can be improved by recent breakthroughs in plastic surgery. 

Summary

Twenty years ago, burns that covered half of the body were almost always deadly. Patients with burns that cover 90% of their body can now live. Burn sufferers' quality of life is continually increasing as wound healing and tissue repair therapies advance.
