The Best Solution for Wound Therapy

Among the different forms of illnesses and conditions that make life difficult for us, wounds that are in a chronic state can be one of the worst as the painful affects that are caused by it can be quite severe. Generally caused by neuropathy and low circulation due totrauma that has occurred repeatedly/old age,the main reason why these wounds can be problematic is that they tend to be very slow, when it comes to healing. Diabetic, pressure and venous ulcers are generally the main types of wounds and one of the most important factors to remember when treating these is to prevent them from getting infected. The best way to protect these wounds is by covering them with dressings/bandages and dead tissue removal, moist wound therapy, antibiotics, etc. are some of the more common forms of treatmentused on them.


Although in some instances the more conventional treatment methods that are mentioned above might not be enough and that is where the therapy known as ‘Negative Pressure Wound Therapy’ or ‘NPWT’, comes into play. This therapy providesnegative pressure generally around (-80)-(-125) mmHgto the bed of the wound which can remove the exudate from the wound and aid in establishing the balance of fluids within it.NPWT is also known to aid in interstitial oedema reducing and improving of blood flow in the small blood vessels as well. Commonly used for acute/chronic wounds,this form therapy can be even used for second/third degree burns as well. Wounds that are dehisced or that have bones in anexposed state, muscle flaps, orthopaedic injuries, skin grafts, etc. can also be treated via NPWT too.

How it Works

When using this mode of therapy on awound, a tube which is connected to the vacuum device is what applies the negative pressure which can be on continuous or intermittent level, according to the type of the wound. The vacuum will usually be threaded with a foam dressing/gauze. There are many devices that are used for NPWT and the device known as ‘Pico’ is one of the most efficient ones among them due to its size and portability.However, you should refrain from using NPWT in conditions where wounds are necrotic, dry or have blood vessels that are exposed.

Benefits of the Therapy

Through NPWT, you will be able to provide a good, moist, healing environment for the wound and will help in reducing the bacteria contamination of the wound. The therapycan also assist in the contraction of the wound while reducing the death of cells due to dehydration too. The time that the therapy needs to be continued will usually depend on the patient’s wound type/size and his/her overall health. In some situations a significant improvement can be seen after the firs dressing change itself, while other times, it might take several weeks of treatment for to see an improvement.NPWT can also be a more cost effective option when comparing with the normal wound care methods, if it is being used more than a couple of days as well.

How often the dressings used on the wound need to be changed,will usually depend according to the fluid amount from the wound and you can get advice from a nurse/doctor if you are having difficulties in determining this.
