- Healing a wound is a rather difficult and frequently prolonged procedure. It serves as evidence of the body’s capacity for regeneration. Various wounds heal at different rates for a variety of reasons.
- First of all, whether a wound is the result of surgery or a disease depends on the type of wound. Additionally, it contains information about the patient’s distinctive features, such as age, diet, and medications used. The health of the human body, immunity, the existence of diseases, etc. all play a significant role in how quickly wounds heal.
Patient's age
- Age-related alterations in healing ability are numerous and widespread. According to studies, physical changes that come with advancing age, such as delayed wound healing, may affect persons over the age of 60.
- Along with the numerous diseases already present, there is a decrease in the body’s inflammatory response, a delay in angiogenesis, and a delayed epithelialization process.
- Age spots and drier skin as a result of decreased sebaceous gland activity are two apparent changes to the skin that are linked to the alteration in melanocytes. Slower scar development during the healing of wounds is also due to decreased collagen synthesis.
Chronic Diseases
- Patients with diabetes or circulatory system disorders may experience slowed wound healing. Effective wound healing requires healthy blood flow, therefore treating chronic diseases that impair blood flow to the wound site may be necessary.
- People with chronic wounds are encouraged to see a doctor for a full examination to determine the most effective treatment options.
Infection
- Every skin break has the potential for the entry of bacteria, viruses, or fungi. Normally, white blood cells and other immune system elements capture and destroy these infections.
- When an infection is present, it can break through the skin and cause sores or lesions that need to be treated with excellent wound care and possibly with medications.
Poor blood circulation
- People with low blood pressure or vascular illness may experience problems with delayed healing because blood transports the components needed for tissue to mend from wounds.
- Issues with the body’s ability to deliver essential wound healing components, such as white blood cells and sufficient oxygen, to injured tissues can also be caused on by blocked or restricted blood vessels or disorders of the heart, kidneys, or lungs.
Poor nutrition
- Poor nutrition can remain in the body with insufficient resources to heal the wound in a chronically unwell or elderly patient. Because infections increase a patient’s need for protein and calories, inadequate nutrition might happen.
- Additionally, wounds can regularly release significant amounts of protein, particularly in the case of leg ulcers or massive pressure ulcers (injuries). The body may break down protein for energy when calories are inefficient, thus reducing the body’s capacity to repair.
Lack of water intake
- Lack of moisture at the wound’s surface can prevent cells from migrating, reduce blood oxygenation, and significantly slow wound healing. Dehydration brought on by a lack of water or sodium can hinder many facets of the healing process.
- Even though the average person needs 64 ounces of fluid per day, those who are trying to heal from a wound will need to consume more in order to facilitate the process of white blood cells travelling to the wound in order to deliver essential oxygen and nutrients.
- Urine from a patient who is adequately hydrated will typically be clear and odourless.
Prolonged Trauma
The healing process for wounds that are repeatedly harmed by shear force or pressure against a surface can be slowed down or even interrupted. Patients who are paralyzed frequently experience repetitive trauma, which can be managed by careful repositioning on a regular basis or by using unloading or protective devices while being closely supervised by a healthcare professional
Type of wound
The features of a wound can influence how quickly it heals. Larger wounds obviously take longer to heal, but the shape of the wound can also influence how long it takes to heal. Circular wounds heal the least quickly, while linear wounds usually mend more quickly than rectangular ones. Additionally, wounds with necrotic tissue, desiccation, and foreign bodies heal more slowly
Edema
- Although the majority of traumatic injuries result in some tissue swelling, severe swelling can put more pressure on blood vessels and worsen blood circulation in the area around the cut.
- Heart disorders and blood vascular issues can also contribute to tissue swelling. In order to minimise swelling and facilitate normal recovery, compression therapy is frequently efficient at transferring fluids back into the circulatory system.
