Wound care techniques for diabetics, the elderly, and those with low immunity PTP

Each type of wound has specific characteristics and complexities that require different care. For example, diabetic wounds are at risk of infection and heal slowly. Chronic infected wounds require special care or continuous medication. Wounds in the elderly need health management as a contributing factor. For wounds in immunocompromised patients, such as cancer patients undergoing chemotherapy, close care is necessary to prevent complications. The details are as follows:
<h2>How to Care for Diabetic Wounds</h2>
Diabetic wounds are often chronic and slow to heal. Regular wound cleaning, along with blood sugar control and foot care to prevent new wounds, is important. The care should be as follows:
<ul>
<li>Self-care for diabetic wounds: Start by gently cleaning the wound using medical saline or mild soap, avoiding substances harmful to tissue such as hydrogen peroxide or alcohol. Cover the wound with a clean or sterilized dressing that helps maintain moisture or absorbs fluids well, such as hydrogel. Avoid using adhesive plasters directly to reduce irritation and excessive moisture accumulation. Also, regularly observe for abnormal symptoms such as swelling, redness, heat, serous fluid, or pus. If these symptoms occur, see a doctor immediately.</li>
<li>Treatment by a specialist doctor: The doctor will examine the wound, which may involve debridement to remove dead tissue and stimulate healing. Antibiotics may be prescribed orally or by injection depending on severity. In some cases, special shoes or walking aids may be needed to reduce pressure on the wound and prevent further friction, helping the wound heal faster and reducing the risk of complications.</li>
<li>Prevention of diabetic wounds: Maintain blood sugar levels within a good range, which is a key factor in preventing diabetic wounds. Take care of foot hygiene by washing feet regularly, drying thoroughly, and checking for abrasions or abnormal skin color changes for timely care. Wear properly fitting shoes that support and prevent severe friction, and avoid walking barefoot, which increases the risk of wounds.</li>
</ul>
&nbsp;
<h2>How to Care for Chronic Infected Wounds (Chronic Infected Wound)</h2>
Chronic infected wounds have a high risk of complications such as recurrent infections, requiring meticulous and consistent care as follows:
<ul>
<li>Wound cleaning: Use medical saline (Normal Saline Solution, NSS), appropriate antiseptics such as 0.05% Chlorhexidine, or wound cleansers recommended by a doctor to avoid tissue damage from harsh chemicals like alcohol. Gently dry the wound with a clean cloth. The use of antibacterial ointments like Mupirocin should be considered and followed according to medical advice.</li>
<li>Cover the wound with gauze: or dressings that absorb fluids such as hydrocolloid, foam dressing, or alginate dressing, which help maintain appropriate moisture and reduce infection risk. However, be cautious when using these on severely infected wounds with pus or heavy exudate, as they may not be suitable. Change dressings every 24-48 hours or more frequently if fluid leaks, and observe the wound for abnormalities. If swelling, redness, or pus occurs, see a doctor immediately.</li>
<li>Overall health care: Monitor and treat underlying diseases that delay healing or increase infection risk to keep them well-controlled. Consume high-protein foods to promote new tissue growth and accelerate wound recovery. Avoid stress and smoking, which impair blood circulation to the wound, causing slow or difficult healing and increasing the risk of infection or complications.</li>
</ul>
&nbsp;
<h2>How to Care for Wounds in the Elderly (Geriatric Wounds)</h2>
Wound care in the elderly requires special caution and attention because their skin is fragile and immunity is reduced, leading to slower healing.
<ul>
<li>Wound cleaning: Wash the wound gently with mild soap or saline. Avoid harsh substances like alcohol that can dry and irritate the wound. Dry the wound and apply antiseptic ointments recommended by a doctor, such as Mupirocin, then cover with a clean or sterile gauze dressing.</li>
<li>Prevention of pressure ulcers: Change the lying position frequently every 2 hours or as advised by a doctor to reduce pressure that may cause pressure ulcers. If difficult, use mattresses or materials that help prevent pressure ulcers along with frequent position changes.</li>
<li>Physical therapy: Helps improve blood circulation and reduce the risk of new wounds.</li>
<li>High-protein diet: Such as fish and eggs, helps build new tissue and speeds up healing.</li>
<li>Wound inspection: If swelling, redness, or pus is found, see a doctor.</li>
</ul>
&nbsp;
<h2>How to Care for Wounds in Immunocompromised Patients (Expanded)</h2>
Wound care in immunocompromised patients, such as those undergoing chemotherapy, HIV-infected patients, or those on immunosuppressive drugs, requires close cooperation between patients, caregivers, and medical teams because these patients have a high risk of infection and slower healing.
<ul>
<li>Wound cleaning: Use sterilized saline or boiled clean water, not tap water directly, which risks infection. Soak cotton or gauze and gently dab instead of rubbing to reduce irritation and preserve new tissue. Avoid harsh substances like alcohol or hydrogen peroxide, which can damage tissue and slow healing.</li>
<li>Infection prevention: Consult a doctor to select appropriate antibiotics based on wound type and severity. Choose suitable dressings such as hydrocolloid or transparent film dressings to maintain wound moisture and prevent contamination. Change dressings frequently or when the wound becomes wet.</li>
<li>Regular wound observation: If swelling, increased redness, pus, abnormal fluid color, or foul odor occurs, which may indicate infection, consult a doctor immediately.</li>
</ul>
Nutrition and immune-boosting medication: Help speed up wound healing. Consume high-protein foods, vitamins, and essential minerals such as vitamin C, zinc, and iron to promote new cell growth and repair damaged tissue.

Wound care is a process that requires caution and deep understanding of wound characteristics, appropriate selection of equipment and materials, and adherence to precautions to prevent infection. This helps wounds heal faster and reduces the risk of complications. If you have questions or problems caring for wounds by yourself, you can consult a specialist doctor at Phyathai Phaholyothin Hospital, who is experienced in treating all types of wounds to receive proper treatment, helping wounds heal quickly without worry and allowing you to return to a quality and happy life.

Diabetic wounds are at risk of infection and often heal slowly. Chronic infected wounds should be cared for by a doctor. Wounds in the elderly often result from fragile skin, so other aspects of health must also be managed. Wounds in patients with low immunity require caution and prevention of complications.
