There are some wounds that take a long time to heal no matter what you do, right? Especially for someone with a condition like diabetes, a wound from a major accident, or a wound after surgery... It's very annoying to wait for these to heal. Today, we're talking about a special treatment method that is used to quickly heal such slow-to-heal, complex wounds.
Simply put, what is Negative Pressure Wound Therapy?
While the name may sound a bit scientific, the process is actually quite simple. It's like a small vacuum cleaner that's placed over a wound. Doctors sometimes call it ``vacuum-assisted therapy.'' In this method, a special bandage is placed over the wound and a small machine attached to it sucks out any debris from the wound.
Imagine, all the unnecessary fluid, pus, and bacteria in a wound are sucked out by this machine. What happens then?
- Swelling (edema) around the wound decreases.
- A clean, moist environment is created inside the wound, allowing new, healthy cells to begin to grow.
- The wound gradually heals and begins to shrink in size.
This way, the wound heals much faster. Usually, after a doctor has performed an operation and cleaned the wound, this treatment can be started in the operating room. Then, a nurse or doctor will come to your ward and change the bandage and check if the machine is working properly. Sometimes, this treatment can be done at home. In that case, you will have to come to the clinic on the scheduled days to change the bandage.
How to do this treatment? Step by step...
The way this is done is very systematic. Your doctor or nursing staff will follow these steps.
1. Cleaning the wound: First, your wound will be thoroughly cleaned and dried. If in an operating room, any dead or infected tissue will be removed from the wound.
2. Placing a special foam: Next, a special foam is cut to fit over or inside the wound.
3. Airtight sealing: The foam is covered with a transparent film that can leak liquid, and a special tape is wrapped around it to seal it so that not even the slightest bit of air can get in .
4. Attaching the suction tube: Now, a suction tube is attached over this sealed bandage.
5. Connecting to the machine: The other end of the tube is connected to a canister that collects fluid from the wound and to a small pump that creates suction.
6. Turning on the machine: Finally, the machine is set to the pressure level prescribed by the doctor and turned on. The contents of the wound will then begin to be sucked out and collected in the canister.
Sometimes, this method can also be used to inject saline or antibiotics into the wound, which can be very helpful in controlling infection.
What types of injuries is this treatment best suited for?
This is not used for every minor scratch. This treatment is especially used for more complex cases. Let's see what it is.
| Opportunity | Description |
|---|---|
| Complex injuries | Large, deep wounds that are difficult to heal. For example , foot ulcers in diabetics. |
| Burns | This is used to speed up the healing process of some severe burns. |
| Traumatic injuries | Injuries that occur after a major accident and have extensive tissue damage. |
| Injuries after surgery | This method can be used if there is a risk of infection or fluid accumulation in a wound that has been stitched after surgery. |
| Chronic injuries | This helps stimulate the healing process of wounds that have not healed for months or years. |
Are there any cases where this treatment should not be done?
Yes, definitely. In some cases, this treatment is not appropriate.
- If the wound exposes internal organs or large blood vessels.
- If there are cancer cells in the area where the wound is located.
- If there is a lot of dead tissue in the wound (which must be surgically removed first).
- If there are abnormal connections (fistulas) between body parts.
What are the advantages and disadvantages of this method?
As with any treatment, there are benefits as well as potential risks or disadvantages. Let's be aware of both.
| Main Benefits | Possible Side Effects |
|---|---|
| ✅ Faster healing. | ❌ Bleeding may occur. |
| ✅ Reduction of swelling and inflammation. | ❌ You may feel some pain. |
| ✅ Increased blood supply to the wound. | ❌ There is a small chance of infection. |
| ✅ No need to change bandages frequently (usually every 48-72 hours). | ❌ The foam may stick to the wound. |
| ✅ Reduction in hospital stay. | ❌ Machine malfunctions such as low battery or clogged hose. |
Things to keep in mind if you are taking this treatment at home:
If your doctor advises you to continue this treatment at home, you need to be very careful about these things.
- Protect from water: Do not bathe while wearing this machine and bandage. Instead, wipe your body with a damp cloth (sponge bath).
- Pain medication: If you are feeling pain, only use painkillers prescribed by your doctor.
- Take the prescribed medications: Take the antibiotics prescribed to prevent infections exactly at the right time and for the right length of time.
| If these things happen, inform your doctor immediately! | |
|---|---|
| 🚨 | If the wound starts to bleed. |
| 🚨 | If you are showing signs of infection, such as fever and chills. |
| 🚨 | If the seal around the wound comes off or becomes loose. |
| 🚨 | If the machine is making a different sound than usual. |
| 🚨 | If the machine's battery is low or the machine turns off automatically. |
Living with a wound, whether after surgery or for any other reason, is not easy. Although this treatment called `Negative Pressure Wound Therapy` may seem a little uncomfortable, it can significantly reduce the healing time of your wound. So, if you feel any discomfort or pain during this treatment, never be afraid to tell your doctor or nursing staff about it.
