Pressure Ulcers
An example of a hard-to-heal wound is a pressure ulcer, otherwise known as bedsore. These form on bony prominences, usually in cases where people are immobilized for extended periods of time such as people who are injured or the elderly.
Non-healing wounds, also called chronic wounds, are those that fail to heal within the usual period of four weeks to three months. These wounds heal at a slow pace and tend to recur. Some common non-healing wounds are diabetic foot ulcers, ischemic wounds, venous leg ulcers, and pressure wounds.
Avulsion. A severe type of wound in which multiple or all layers of the skin and tissue are ripped off is known as an avulsion. These are very serious and cause the injured to lose a great deal of blood if the bleeding is not stopped right away.
The type, size, and severity of a wound can affect how quickly it heals — shallow cuts heal more quickly than deep lacerations, clean wounds heal faster than infected ones, and linear wounds tend to improve more quickly than round ones.
Cartilage is avascular, meaning that it has no blood supply. The lack of blood circulation in cartilage means that it is a very slow-healing type of tissue. Nutrition to cartilage is maintained by fluid in the joints, which lubricates the tissue.
Chronic wounds are defined as wounds that fail to proceed through the normal phases of wound healing in an orderly and timely manner. Often, chronic wounds stall in the inflammation phase of healing.
Wounds that are sutured in an unsterile environment, or are not cleansed, irrigated, and debrided appropriately, are at high risk for infection due to contamination.
Open wounds are more likely than closed wounds to develop infections because broken skin allows easy access for germs. An abrasion is when your skin scrapes against a rough surface, for example if you fall off a bicycle.
Traumatic wounds are typically defined as cuts, lacerations or puncture wounds which have caused damage to both the skin and underlying tissues. Acute wounds, cut wounds and penetrating wounds are the three categories that make up traumatic wounds.
Chronic non-healing wounds are the wounds that do not heal even after a few months or years, secondary to an underlying disease which may interfere with the normal healing process. Chronic wounds can be painful and can adversely affect the quality of life of the patient.
Acute wounds are those that heal without any complications in a predicted amount of time. While chronic wounds, on the other hand, are those that take a relatively long time to heal with some complications.
The factors discussed include oxygenation, infection, age and sex hormones, stress, diabetes, obesity, medications, alcoholism, smoking, and nutrition. A better understanding of the influence of these factors on repair may lead to therapeutics that improve wound healing and resolve impaired wounds.
A burn injury is one of the most painful injuries a person can endure, and the subsequent wound care required to treat it is often more painful than the initial trauma [1]. Severe burn injuries are almost always treated in surgical units and preferably in multidisciplinary burn centers.
When cared for properly, most wounds heal well, leaving only a small scar or none at all. With larger wounds, you are more likely to have a scar. Certain factors can prevent wounds from healing or slow the process, such as: Infection can make a wound larger and take longer to heal.
The most common types of chronic wounds include ulcers, infectious wounds, ischemic wounds, surgical wounds, and wounds from radiation poisoning. Ulcers are the most common type of chronic wounds.
Deeper lacerations may take several weeks and even months to completely heal, and they may require stitches and other treatment from medical professionals to prevent complications and scarring.
Healthy granulation tissue is pink in colour and is an indicator of healing. Unhealthy granulation is dark red in colour, often bleeds on contact, and may indicate the presence of wound infection. Such wounds should be cultured and treated in the light of microbiological results.
Any wound that isn't properly cleaned and covered can allow bacteria, viruses or fungi to enter through the opening in the skin, leading to infection. Sepsis occurs when the body overreacts to infection, releasing chemicals into the bloodstream that ultimately cause organ failure and death.
High risk wounds are those that have an increased incidence of infection due to the type of wound, location, or the patient's underlying medical condition.
If a person does not receive treatment for a wound infection, the infection can spread to other parts of the body, which may lead to serious complications, including: Cellulitis is an infection of the deeper layers and tissues of the skin, and it can cause swelling, redness, and pain in the affected area.
A wound that has not healed within four weeks is chronic and needs medical attention by a professional wound care specialist. Without treatment, these types of wounds can increase your risk of serious health complications, such as infection, tissue loss, and even limb amputation.
Individuals living with a chronic wound can experience chronic pain, loss of function and mobility, increased stress, social isolation, depression and anxiety, prolonged hospitalization, and even a higher risk of death.
If you think any of your wounds are healing too slowly, or could be infected, see your doctor for treatment, as well as to rule out any more serious health issues that may need to be checked. And you should always speak with your physician before altering your medication regimen.
