Benefits of using NPWT

Wound Healing is a complex and dynamic process. It involves 3 to 4 distinctive phases in order to replace devitalised and missing cellular structures and tissue layers.

Wound healing is a normal biological process of human body.

But, healing gets delayed when wounds become infected with harmful microorganisms. If left untreated, there is also a risk of the infection spreading to other body parts.

Negative Pressure Wound Therapy (NPWT) is an effective procedure for the treatment of wounds of various aetiologies and is not less than any gold standard technique for the management of complex non-healing wounds.

It involves applying a continued sub-atmospheric pressure at wound bed site, to increase blood flow to the area and withdraw excess fluid from the wound to promote wound healing.

NPWT system consists of a dressing and a vacuum source. The various components of dressing include an open pore foam, a transparent adhesive dressing, a tubing to connect the dressing with a vacuum pump producing negative pressure and a canister to collect the exudates. The technique is used an adjunct to surgical debridement to treat tissue defects around open fractures and chronic, contaminated wounds.

Do You Know? “The advent of modern NPWT systems is attributed to Argentas and Morykwas, who developed several prototypes to facilitate wound healing by distributing suction across wounds to help draw the skin edges together- Annals of Plastic Surgery”.

Mechanism of Action:
NPWT facilitates wound healing at both macroscopic & microscopic levels. 

– The primary mechanism of action includes wound edges contraction called “tissue macro-deformation” powered by the suction, distributed through the dressing foam.

– Secondly, NPWT results in “micro-deformation” by promoting cell division and proliferation, growth factor production and angiogenesis.

-Next important step includes the removal of oedematous fluid and exudates from the extracellular space, thereby removing inflammatory chemicals and cytokines.

– A warm and moist environment wards off wound desiccation and enhances the formation of granulation tissue.

Clinical Indications:
NPWT therapy has been studied across all medical and surgical specialties and as of Jan.2014, the technique has been mentioned in over 861 peer-reviewed journals. Its potential has been demonstrated in various contaminated, difficult to treat wounds covering both acute and chronic types.

There have been increasing evidences on NPWT’s ability to aid the closure of various acute wounds such as Traumatic & Surgical Wounds and Subacute & dehisced wounds. NPWT technique is found to be valuable in management of various chronic wounds such as Pressure Ulcers, Diabetic Foot Ulcers (DFU), Arterial and Venous Leg Ulcers. Applying NPWT to a newly laid down skin graft is gaining importance with a number of studies showing an improvement in graft incorporation by using a pressure ranging between -50 to -80 mmHg. 

The benefits of using NPWT over conventional dressings have been documented. 

– The therapy offers a non-invasive treatment with one of the major advantage being reduction in number of dressing changes, which in turn improves compliance as the patient suffers less pain and inconvenience when compared with conventional dressings. 

– The negative pressure removes excess fluid allowing for enhanced circulation and disposal of cellular waste, thereby reducing the risk of bacterial contamination.

-NPWT eases the formation of a local infection-free healing tissue in a short period of time. Thereby, preventing the need for complex surgical procedures for the final coverage of important structures. 

-A faster reduction in the wound size and formation of granulation tissue with rapid wound closure has been observed as compared to conventional dressings.

-The speedy wound management with NPWT enables transfer from hospital to lower-cost health care setting. Apart from these its saving on the dressing & nursing costs too.

Specific Considerations for Different Wounds

When it comes to wound care, one size does not fit all. Each wound has its own unique characteristics and possible complications. Tailoring first aid steps to specific types of injuries can significantly impact healing outcomes and minimize complications.

In this blog post, we look at different wounds with specific considerations emphasising the need for individualised care and additional precautions to enhance better results.

Understanding Different Wounds:

1. Burns:

First-degree burns: These affect only the outer layer of skin, causing redness and mild pain. Immediate first aid involves cooling the burn with cold water or a clean, damp cloth and then applying aloe vera gel. Cover the burn area with a sterile non stick bandage, this will help protect the damaged area from contaminants and the sun. 

Second-degree burns: These penetrate deeper into the skin, going through the first and second layer of the skin, causing blistering and severe pain. First aid includes cooling the burn, covering it loosely with a sterile gauze bandage, and seeking medical attention.

Third-degree burns: These are the most severe, affecting all layers of the skin and potentially deeper tissues. Third degree burns should always be treated by a healthcare provider and never at home. First aid involves not removing any clothing stuck to the burn, covering it with a clean, dry cloth, and seeking emergency medical help immediately.

2. Deep Cuts:

2a. Apply pressure: Use a sterile gauze pad or clean cloth to apply firm pressure to stop bleeding.
2b. Clean the wound: Once the bleeding has stopped rinse the cut with clean water to remove any debris and dirt.
2c. Bandage the wound: Once it has been cleaned properly, cover the cut with a sterile bandage or gauze pad and secure it with medical tape.
2d. Seek medical attention: Deep cuts may require stitches to promote proper healing and reduce the risk of infection.

3. Abrasions:
Abrasions, also known as scrapes, occur when the skin is rubbed or scraped against a rough surface, causing superficial damage.

3a. First aid involves cleaning the abrasion with soap and water to remove debris and applying an antibiotic ointment to prevent infection.
3b. Cover the abrasion with a sterile bandage or gauze pad to protect it from further irritation and promote healing.
3c. Change the dressing on a regular basis and check the area daily
3d. If there are any signs of an infection such as, fever, swelling, an increase in redness or fluid seek medical help from a healthcare provider.

4. Puncture Wounds: 
Puncture wounds are caused by sharp objects piercing the skin, such as nails, needles, or animal bites. Such types of wounds have a greater risk of infection as bacteria are being pushed into the skin.

4a. First aid involves cleaning the wound thoroughly with soap and water to remove any dirt or debris.
4b. Do not attempt to remove any object embedded in the skin. Instead, stabilize the object and seek medical attention immediately.
4c. Cover the puncture wound with a clean cloth or sterile bandage to reduce the risk of infection until medical help arrives.

Therefore, understanding the characteristics and appropriate first aid measures for different types of wounds is essential for providing effective care and promoting optimal healing outcomes.

Tailored First Aid:

Children:
a. Children’s skin is more delicate and prone to infection. Use extra caution when cleaning and bandaging wounds.
b. Consider using adhesive bandages with fun designs to make the first aid process less intimidating for children.

Elderly:
a. Elderly individuals may have thinner skin and reduced circulation, making them more susceptible to skin tears and slow wound healing.
b. Be gentle when cleaning and bandaging wounds to avoid causing further damage.

Individuals with Diabetes:
a. Diabetes can impair blood flow and reduce sensation in the extremities, increasing the risk of foot ulcers and slow-healing wounds.
b. Inspect feet daily for any signs of injury and seek prompt medical attention for any cuts or sores.

Precautions and Practices – 
In addition to first aid measures designed for specific wound types, there are several precautions and practices to keep in mind:

1. Always wash your hands thoroughly before and after your first treatment to prevent the spread of infection.
2. Use disposable gloves when treating the wound to reduce the risk of contamination.
3. Avoid using alcohol or hydrogen peroxide directly on the wound, as it can damage healthy tissue.
4. Keep first aid kits safe and easily accessible in an emergency.

Tailoring first aid measures to specific types of wounds is crucial for effective treatment and optimal healing. Whether it’s a minor burn or a deep cut, understanding the unique needs of each injury and taking appropriate action can make a significant difference in recovery outcomes and help in reducing the risk of complications.

In moments of crisis, such as accidents or emergencies, being equipped with the knowledge and skills to administer proper wound care can make a critical difference in saving lives and preventing further complications.

Whether you’re a bystander or the injured person themselves, understanding the essential steps of wound care in emergency situations is paramount. 

Here are some quick response tips to guide you through assessing and managing wounds effectively:

Assessment and Safety First:
The foremost priority in any emergency situation is safety. Before rushing to aid the injured person, take a moment to assess the surroundings for potential hazards. Ensure both your safety and that of the injured individual by identifying and eliminating any immediate dangers.

Control Bleeding:
One of the most crucial steps in wound care is controlling bleeding. Apply direct pressure to the wound using a clean cloth or dressing. Elevating the injured area, if feasible, can help reduce blood flow and minimize bleeding. Prompt action in staunching the blood flow can prevent further loss and stabilize the individual’s condition.

Clean the Wound Quickly:
After addressing the bleeding, it’s essential to clean the wound promptly. Rinse the wound gently with clean water to remove any debris or foreign objects. In emergency situations, it’s advisable to avoid using strong antiseptics or solutions unless absolutely necessary, as they can cause further irritation or delay in treatment.

Apply Dressing and Bandage:
Once the wound is cleaned, cover it with a sterile dressing or a clean cloth to protect it from contamination. Secure the dressing in place using a bandage or cloth, ensuring it is snug but not too tight to impede circulation. Proper dressings help create an optimal environment for wound healing while preventing infection.

Seek Medical Assistance:
While initial wound care is essential, it’s crucial to recognize the severity of the injury and seek professional medical assistance promptly. Call emergency services or transport the individual to the nearest medical facility if the wound is severe, deep, or if bleeding persists despite initial measures. Timely medical intervention can prevent complications and facilitate proper wound management.

Prevent Shock and Comfort the Injured:
In addition to physical care, it’s vital to address the emotional and psychological needs of the injured person. Keep them calm and reassured to prevent shock, covering them with a blanket to maintain body warmth and comfort. Offering words of encouragement and support can go a long way in alleviating distress.

Continued Monitoring and Updates:
Even after administering initial first aid, it’s essential to continue monitoring the injured person’s condition until professional help arrives. Stay vigilant for any signs of deterioration or changes in vital signs, providing updates and relevant information to emergency responders upon their arrival. Your ongoing support and assistance can contribute significantly to the individual’s overall well-being and recovery.

Therefore, effective wound care in emergency situations requires a combination of swift action, sound judgment, and compassion. By prioritizing safety, controlling bleeding, cleaning the wound, seeking medical assistance, providing comfort, and monitoring the individual’s condition, you can help ensure the best possible outcome for the injured person. Remember, every second counts in an emergency, and your actions can make a lifesaving difference.
