Non-healing wounds -
Negative pressure wound therapy NPWT is a treatment that improves ischemic tissues and removes wound fluid used by bacteria. Recent technological advancements produced novel approaches such as self-adaptive wound dressings [39] that rely on properties of smart polymers sensitive to changes in humidity levels.
The dressing delivers absorption or hydration as needed over each independent wound area and aids in the natural process of autolytic debridement. It effectively removes liquefied slough and necrotic tissue, disintegrated bacterial biofilm as well as harmful exudate components, known to slow the healing process.
Persistent chronic pain associated with non-healing wounds is caused by tissue nociceptive or nerve neuropathic damage and is influenced by dressing changes and chronic inflammation. Chronic wounds take a long time to heal and patients can experience chronic wounds for many years.
It is important to remember that increased wound pain may be an indicator of wound complications that need treatment, and therefore practitioners must constantly reassess the wound as well as the associated pain. Optimal management of wounds requires holistic assessment.
Documentation of the patient's pain experience is critical and may range from the use of a patient diary, which should be patient driven , to recording pain entirely by the healthcare professional or caregiver.
The more frequently healthcare professionals measure pain, the greater the likelihood of introducing or changing pain management practices. At present there are few local options for the treatment of persistent pain, whilst managing the exudate levels present in many chronic wounds.
Important properties of such local options are that they provide an optimal wound healing environment, while providing a constant local low dose release of ibuprofen while worn. If local treatment does not provide adequate pain reduction, it may be necessary for patients with chronic painful wounds to be prescribed additional systemic treatment for the physical component of their pain.
Clinicians should consult with their prescribing colleagues referring to the WHO pain relief ladder of systemic treatment options for guidance. For every pharmacological intervention there are possible benefits and adverse events that the prescribing clinician will need to consider in conjunction with the wound care treatment team.
Blood vessels constrict in tissue that becomes cold and dilate in warm tissue, altering blood flow to the area. Thus keeping the tissues warm is probably necessary to fight both infection and ischemia. Underlying ischemia may also be treated surgically by arterial revascularization , for example in diabetic ulcers, and patients with venous ulcers may undergo surgery to correct vein dysfunction.
Diabetics that are not candidates for surgery and others may also have their tissue oxygenation increased by Hyperbaric Oxygen Therapy , or HBOT, which may provide a short-term improvement in healing by improving the oxygenated blood supply to the wound.
Low level laser therapy has been repeatedly shown to significantly reduce the size and severity of diabetic ulcers as well as other pressure ulcers.
Pressure wounds are often the result of local ischemia from the increased pressure. Increased pressure also plays a roles in many diabetic foot ulcerations as changes due to the disease causes the foot to have limited joint mobility and creates pressure points on the bottom of the foot.
Effective measures to treat this includes a surgical procedure called the gastrocnemius recession in which the calf muscle is lengthened to decrease the fulcrum created by this muscle and resulting in a decrease in plantar forefoot pressure.
Since chronic wounds underexpress growth factors necessary for healing tissue, chronic wound healing may be speeded by replacing or stimulating those factors and by preventing the excessive formation of proteases like elastase that break them down. One way to increase growth factor concentrations in wounds is to apply the growth factors directly.
This generally takes many repetitions and requires large amounts of the factors, although biomaterials are being developed that control the delivery of growth factors over time. In other cases, skin from cadavers is grafted onto wounds, providing a cover to keep out bacteria and preventing the buildup of too much granulation tissue , which can lead to excessive scarring.
Though the allograft skin transplanted from a member of the same species is replaced by granulation tissue and is not actually incorporated into the healing wound, it encourages cellular proliferation and provides a structure for epithelial cells to crawl across.
Collagen dressings are another way to provide the matrix for cellular proliferation and migration, while also keeping the wound moist and absorbing exudate.
Since levels of protease inhibitors are lowered in chronic wounds, some researchers are seeking ways to heal tissues by replacing these inhibitors in them.
Research into hormones and wound healing has shown estrogen to speed wound healing in elderly humans and in animals that have had their ovaries removed, possibly by preventing excess neutrophils from entering the wound and releasing elastase.

If you are in Maryland, and are curious to understand the options available for treating non-healing wounds, consider visiting the vascular specialists at Center for Vascular Medicine for testing and evaluation.
Each patient is unique, and because of this, there is no one-size-fits-all treatment method. But before we discuss treatment options, let's understand what a non-healing wound is. A non-healing wound, also known as a chronic wound, begins as a skin ulceration and can eventually affect various body parts, including skin, bones, tendons, muscles, and joints.
A chronic wound is one that does not show any signs of healing within four weeks of onset and persists beyond eight weeks. As mentioned earlier, these wounds take time to heal. Patients with chronic wounds often notice certain symptoms in the early development stage, including chronic pain, oozing, feeling a warm sensation around the wound, discoloration on the edges of the wound, itchiness, an odor, or any combination of the above.
Awareness about the options available for treatment for your particular type of wound will be crucial. Identifying the cause of your wound is a significant first step. This is because different types of non-healing wounds require specific treatments. If you, or someone you love, has been suffering with non-healing wounds for years, it is essential you seek the advice of your PCP or vascular specialist.
Oftentimes, an attempt to self-diagnose a wound can lead to negative outcomes. The causes of non-healing wounds are very diverse and require the help of a medical practitioner to identify the exact cause and provide a comprehensive treatment plan for your specific wound.
Treatment and care of a chronic wound depend on the cause. Some of these factors include the type, location, size, and stage of your wound. It is important to understand that chronic wounds have unique characteristics and symptoms requiring specific treatment methods.
Because of this, it is essential to seek the help of a medical professional who understands the various treatment methods available for your particular non-healing wound. Sometimes, your physician may need to incorporate multiple treatment methods to heal your wound.
Additionally, when a specific treatment method is deemed ineffective, a specialist will be able to offer the next phase of your treatment plan.
Moisture is one of the most vital factors in wound healing. Hydration helps increase blood circulation and the formation of new skin cells. When you have a chronic wound, it is essential to keep it clean and moist. By keeping your wound covered with a clean and moist dressing, typically applied using sterile gauze and saline, you will be able to keep the wound protected and allow your skin to heal.
As the dressing dries, the unhealthy tissue is removed and the wound is given the best chance of healing by promoting healthy blood flow to facilitate new skin growth. This approach should be closely monitored by a physician, as some individuals will need to be placed on prophylactic antibiotics to prevent infection.
If you are suffering from a chronic cavity wound, the best option would be to fill it. Packing a chronic wound helps remove debris and fill the dead space to support healing from the wound's base to the surface.
Providing the appropriate pressure to the wound stimulates circulation to the area and facilitates the body's ability to grow healthy tissue. Several wound packing options, such as calcium alginate dressings, saline and betadine dressings, and Hydrofiber dressing, can help you heal your wound and treat it properly.
What your specialist chooses will depend on the severity and location of the wound; as well as the root cause of your non-healing wound. Sometimes, a doctor may recommend using a stimulating agent, such as vac therapy, to help your wound heal. These agents encourage the regrowth of normal tissues and healing, while simultaneously packing the wound.
These therapies can dramatically decrease the healing time of a wound for the right candidate. Your specialist can discuss it in more detail. Enzymatic treatment incorporates the use of naturally occurring proteinases or proteolytic enzymes, which assist in the breakdown of the dead tissue, which helps the wound heal.
These agents are often used in conjunction with other treatment options. In case of a chronic wound that has bled for several days, hemostatic agents may be used to stop the bleeding. These medications help stop the bleeding by promoting blood clotting and will only be used when necessary.
Using antimicrobial agents such as silver nitrate, honey, or other natural substances are sometimes used for preventing infection in your wound. It is important to remember that these treatments will not cure an infected wound but only prevent new infections.
Be sure to consult with your medical provider before applying anything to your on-healing wound. It is imperative to treat not only the existing wound, but also the root cause behind the wound to prevent new wounds from forming. You can treat a non-healing wound in various doctor's offices.
