Prevena™ is a vacuum device that helps your wound heal quickly and protects it from infection. How does Prevena™ work? It makes a vacuum that helps hold the edges of a wound together and removes fluid from the area.
The device is single use and can stay in place for up to 7 days. Prevena is available in a range of sizes and can be customised to fit any incisions. Prevena uses a stabilisation layer to make sure there is full and airtight adhesion to the skin.
A therapy unit that provides negative pressure to the dressing. A dressing with a water resistant cover that is placed over your incision. A connection tube. A canister where incision fluid is collected. A battery charger (The PREVENA PLUS™ Therapy Unit has a rechargeable battery)
Leak Alert Check for leak: at tubing connectors and at connection to canister. After the 7 day lifespan of the unit is complete, the PREVENA PLUS™ 125 Therapy Unit will shut off. The therapy unit, power supply, accessories and dressing should be removed by your doctor or nurse.
A single Prevena unit cost is $495; although this is significantly greater than other dressings, the use of Provena may potentially save on in-hospital stay cost and treatment of infection. In this study, total cost of 52 Prevena units was $25,740.
PREVENA™ Therapy is a portable, disposable system, which uses negative pressure (like a vacuum) to protect your incision. You will be provided after surgery with the PREVENA™ PEEL & PLACE™ System or the PREVENA PLUS™ System.
Length of Wound Vac Treatment
For those who are wondering how long a wound vac needs to stay on, most healthcare professionals recommend changing the dressing every 48 to 72 hours or at least three times a week. If the wound is infected, it may require the dressing to be changed more often.
The machine will ‘beep/light up’ to alert you when there is a problem (see page 3). The purple dressing has a silver layer which touches the skin. This helps to decrease the risk of infection. Prevena runs on batteries for up to 8 days and then shuts itself off.
VAC therapy shouldn’t hurt, and if it does it can indicate a complication. Many people experience discomfort when VAC bandages are changed. In some cases, a medical professional might administer pain medication 30 to 60 minutes before changing the bandages.
For a non-infected wound: KCI recommends the V.A.C. ® Dressings be changed every 48 to 72 hours, but no less than 3 times per week. For infected wounds: These wounds must be monitored often and very closely. Infected wounds dressing changes may need to be changed more often than 48 to 72 hours.
Insert the canister into the PREVENA™ 125 Therapy Unit and slide inward until canister clicks. Canister is fully inserted when the side tabs are flush with the body of the therapy unit. TIP: Wall suction can be used for quicker draw down before transfer to the PREVENA™ 125 Therapy Unit.
If the lifecycle expires while therapy unit is on, a beep will sound for 15 seconds and then automatically shut off. To ensure proper application of the PREVENA™ Dressing, the PREVENA™ 125 Therapy Unit provides the VISICHECK™ Feature.
“Blockage/Canister Full” – If there is a blockage or kink in the tubing or the canister is full, the audible alarm will sound. The canister should be changed or the tubing blockage removed. “Leak or High Flow” – If there is a leak at the wound dressing site or between the wound and the device, the alarm will sound.
