Some studies suggest that involving burn experts in treatment can improve outcomes. It is important to treat road rash as soon as possible after sustaining the injury.
Cleaning out the wound is essential to prevent infection and remove any foreign bodies that may be in the wound. Doing so will help prevent a form of scarring known as tattooing.
It is vital to clean and dress the wound every day. To do so, a person can follow these steps:. As road rash heals, the skin can feel itchy or as though it is being stretched. A person may wish to apply moisturizer frequently to keep the skin soft. For healthcare professionals, two of the key steps in diagnosing road rash are performing a thorough physical examination and learning when the incident happened, how it took place, and what injured the skin.
Abrasions can be linear such as when they are due to a scratch or appear in groups as a result of dragging the skin over an uneven surface. In some cases, the road rash wound can even take on the pattern of whatever it was that damaged the skin.
Road rash usually heals with a few days of home care, but some injuries may be deep enough to require medical attention. Learn more about recognizing and treating an infected wound here. If the person has diabetes or cardiovascular problems, or if they have not had a tetanus shot in over 10 years , it is important to seek medical help right after the injury that caused the road rash.

Keeping the wound clean and preventing infection are the main objectives when it comes to treating these types of injury. Without treatment and effective cleaning, foreign bodies — such as dirt or pebbles — can get trapped in the skin.
This can cause a type of scarring called traumatic tattooing. An open wound leaves internal tissue exposed. They require special care depending on the type of wound. Is itching something to worry about? When you injure yourself and cut, scrape, or burn your skin, blood begins to clot in order to stop the blood from excessively leaving your body.
Blood clotting happens thanks to cells called platelets. Eventually, when the wound stops bleeding, a scab forms. The scab helps protect the freshly injured skin from contaminants like bacteria and allows the skin to heal. Underneath a scab, your body is working hard to repair damage to the skin and blood vessels. The body also enlists white blood cells to help clean up any foreign matter and bacteria in the wound. After some time, a scab will fall off to reveal brand-new skin. Deep wounds and severe burns require emergency medical treatment.
But most small nicks, cuts, scrapes, and surface burns heal well on their own in a healthy person. Itching occurs as a normal part of healing. However, the reason the itch develops isn't completely understood. One study from suggests that the same mechanisms at work with eczema itchiness are involved in itching during wound healing. Additionally, itching that occurs during wound healing might be the result of poorly translated nerve signals.
Your brain might receive a signal that your skin is regenerating via collagen synthesis, but that information is translated as an itching sensation. And so, what you feel is that itching sensation. While some experts believe histamines, which are released by the body to help with wound healing, may contribute to itching, research suggests that their effect may be minimal.
Signs that a wound may be infected include:. Scratching an itch feels great. Scratching an itchy wound that is in the process of healing, however, can cause scarring and prolong healing if you open the wound back up again.
You might even introduce bacteria, causing an infection to develop. Proper care ensures the wound heals without complications and lessens your chances of getting a scar. For a minor wound:. Some wounds require stitches. By alleviating the itch, you can avoid a prolonged healing process and potential infection from scratching too much. Here are a few ways to stop the itching:.
It may also help to find effective distractions from the itching. If itching is very severe and there is a high risk of infection, your healthcare provider may recommend a sleep medication or a neuropathic drug called Neurontin gabapentin to help you rest and decrease the urge to itch.
Some people are at a higher risk of experiencing slow wound healing, which can lead to infection. The following people have a higher risk of complications from a wound:. If you tend to scratch in your sleep, you may want to wear hand coverings. Once the blood clot is formed, an increase in blood flow to the area stimulates cells to travel to the area of injury to destroy bacteria and release substances that support the formation of new skin cells to repair the injury.
Approximately five days after injury to the skin occurs, fibroblasts and skin cells migrate into the wound to form granulation tissue, specific connective tissue that forms in the area of a wound to promote healing. Dead cells are broken down and removed, and tissue healing begins in this stage. Two days after injury to the skin, cells begin to form blood vessels near the edges of the wound.
These blood vessels begin to proliferate, or increase in number, to promote a network for delivering oxygen and nutrients to support the healing skin tissue. The process of forming new blood vessels is called angiogenesis.
As the number of inflammatory cells decreases at the area of injury, new cells migrate to the wound to repair the skin. These cells form collagen and elastin, structural proteins that cross together to form a scar. In the final stage of wound healing, the scar tissue that forms is remodeled to a smoother appearance that is reduced in thickness and redness as the concentration of blood vessels in the area decreases.
The remodeling phase of wound healing can take years to fully lighten a scar to more closely resemble regular skin tissue. Even under ideal conditions, the repaired tissue that forms when an injury to the skin heals never regains its full strength and stability. Many of the cells involved in the stages of wound healing release cytokines , inflammatory proteins that, in addition to increasing the inflammatory response, can cause itching.
Changes in the level of pH and nerve signaling stimulated by tissue tension as an open wound begins to close and heal may lead to itching as well. Specialized sensory nerve cells in the skin—called pruriceptive neurons—respond to these changes and send signals to the brain, where the sensation of itch is recognized. Wound dryness that develops as a scab forms and hardens can also cause itching, potentially by blocking sweat ducts and activating enzymes that increase itching.
As a wound heals, the itching sensation decreases as nerve stimulation and blood flow to the area slow down. Complications can occur that cause wounds to become chronic, taking a very long time to heal or not heal at all.
Three main factors that impair the ability of wounds to heal include:. All tissues of the body require a good blood supply to get oxygen. When blood flow is disrupted through damage to blood vessels, tissues become deprived of oxygen, which leads to cell damage, and in severe cases, cell death. Cells that are involved in the wound healing process have high demands for oxygen. Prolonged lack of oxygen, called hypoxia, can significantly delay wound healing. Factors that contribute to poor circulation and reduced blood flow and supply of oxygen include:.
Proteases, also called proteolytic enzymes, are found in the fluid that leaks from wounds. While they are essential for wound healing by breaking down proteins and restructuring the skin, they can become harmful to wound healing when there is excess activity as a result of chronic inflammation. Proteolytic enzymes are released by cells involved in tissue repair that are stimulated by the inflammatory response.
During the normal phases of wound healing, proteases reach peak levels three days after injury and decrease after day five. With non-healing wounds, levels of proteases peak significantly higher at day three and persist for much longer, causing a destructive environment that does not promote wound healing. A class of medication called protease inhibitors can be helpful for promoting healing of chronic wounds to lower the activity of these destructive enzymes.
When the skin becomes damaged, bacteria naturally found on the skin surface can enter the wound and cause infection. Bacteria can also stick together in a wound, forming a protective biofilm that decreases the ability of white blood cells to fight off the infection and reduces the effectiveness of antibiotic medication.
You should contact your doctor if you think your wound is infected. In addition to a slowly healing or non-healing wound, signs of an infection include:. You should avoid scratching at a scab so that you do not cause further breaks in the skin, which can disrupt the healing process and increase the risk of infection and scarring.
