CLINICIAN GUIDE PREVENA™ INCISION MANAGEMENT SYSTEM
KCI CONTACT INfORMATION IS LOCATED IN ThE bACK Of ThIS GUIDE IMPORTANT As with any prescription medical device, failure to carefully read and follow all instructions and safety information prior to use may lead to improper product performance. INDICATION fOR USE The Prevena™ Incision Management System is intended to manage the environment of surgical incisions that continue to drain following sutured or stapled closure by maintaining a closed environment and removing exudate via the application of negative pressure wound therapy. OPTIMUM USE CONDITIONS For maximum benefit the Prevena™ Incision Management System should be applied immediately post surgery to clean surgically closed wounds. It is to be continuously applied for a minimum of 2 days up to a maximum of 7 days. It can transition home with the patient; however, all Prevena™ Incision Dressing changes should be performed under direct medical supervision. The Prevena™ Incision Management System will not be effective in addressing complications associated with the following: • Ischemia to the incision or incision area • Untreated or inadequately treated infection • Inadequate hemostasis of the incision • Cellulitis of the incision area The Prevena™ Incision Management System should not be used to treat open or dehisced surgical wounds or on patients who have excessive amounts of exudate from the incision area which may exceed the Prevena™ 45mL Canister. The V.A.C.® Therapy System should be considered for treatment of these wounds. The Prevena™ Incision Management System should be used with caution in the following patients: • Patients with fragile skin surrounding the incision as they may experience skin or tissue damage upon removal of the Prevena™ Incision Dressing • Patients who are at an increased risk of bleeding from the incision associated with the use of anticoagulants and/or platelet aggregation inhibitors CONTRAINDICATION: • Sensitivity to silver. WARNINGS • Bleeding: Before applying the Prevena™ Incision Management System to patients who are at risk of bleeding complications due to the operative procedure or concomitant therapies and / or co-morbidities, ensure that hemostasis has been achieved and all tissue planes have been approximated. If active bleeding develops suddenly or in large amounts during therapy, or if frank blood is seen in the tubing or in the canister, the patient should leave the Prevena™ Incision Dressing in place, turn off Prevena™ 125 Therapy Unit and seek immediate emergency medical assistance. • Infected Wounds: As with any wound treatment, clinicians and patients / caregivers should frequently monitor the patient’s wound, periwound tissue and exudate for signs of infection, or other complications. Some signs of infection are fever, tenderness, redness, swelling, itching, rash, increased warmth in the wound or periwound area, prulent discharge, or strong odor. Infection can be serious, and can lead to complications such as pain, discomfort, fever, gangrene, toxic shock, septic shock and/or fatal injury. Some signs or complications of systemic infection are nausea, vomiting, diarrhea, headache, dizziness, fainting, sore throat with swelling of the mucus membranes, disorientation, high fever, refractory and / or orthostatic hypotension, or erythroderma (a sunburn-like rash). Silver in the interface layer of the Prevena™ Incision Dressing is not intended to treat infection, but to reduce bacterial colonization in the fabric. If infection develops, Prevena™ Therapy should be discontinued until the infection is treated. • Allergic Response: The Prevena™ Incision Dressing has an acrylic adhesive coating and a skin interface layer with silver, which may present a risk of an adverse reaction in patients who are allergic or hypersensitive to acrylic adhesives or silver. If a patient has a known allergy or hypersensitivity to these materials, do not use the Prevena™ Incision Management System. If any signs of allergic reaction, irritation or hypersensitivity develop, such as redness, swelling, rash, urticaria, or significant pruritus, patient should consult a physician immediately. If bronchospasm or more serious signs of allergic reaction appear, the patient should turn off the therapy unit and seek immediate emergency medical assistance. • Defibrillation: Remove the Prevena™ Incision Dressing if defibrillation is required in the area of dressing placement. Failure to remove the dressing may inhibit transmission of electrical energy and / or patient resuscitation. • Magnetic Resonance Imaging (MRI): The Prevena™ 125 Therapy Unit is MR Unsafe. Do not take the Prevena™ 125 Therapy Unit into the MR environment. The Prevena™ Incision Dressing can typically remain on the patient with minimal risk in an MR environment. Interruption of Prevena™ Therapy during MRI may reduce the effectiveness of Prevena™ Therapy. The Prevena™ Incision Dressing should pose no known hazards in an MR environment with the following conditions of use: static magnetic field of 3 Tesla or less, spatial gradient field of 720 Gauss/cm or less, and maximum whole-body-averaged specific absorption rate (SAR) of 3W/kg for 15 minutes of scanning. • Diagnostic Imaging: The Prevena™ Incision Dressing contains metallic silver that may impair visualization with certain imaging modalities. • Hyperbaric Oxygen Therapy (HBO): Do not take the Prevena™ 125 Therapy Unit or Prevena™ Incision Dressing into a hyperbaric oxygen chamber; it is not designed for this environment, and should be considered a fire hazard. If Prevena™ Therapy is reinitiated after HBO treatment, do not readhere the same dressing, a new dressing must be applied. • Canister Full: If at any time while using the Prevena™ Incision Management System, the canister becomes full of fluid other than blood, indicated by a Maximum Capacity Alert or visual inspection, the patient should turn therapy unit off and contact the treating physician. PRECAUTIONS • Standard Precautions: To reduce the risk of transmission of bloodborne pathogens, apply standard precautions for infection control with all patients, per institutional protocol, regardless of their diagnosis or presumed infection status. In addition to gloves, use gown and goggles if exposure to body fluid is likely.

• Circumferential Dressing Application: Avoid applying the Prevena™ Incision Dressing circumferentially. In cases where the clinician determines that the benefits of applying the Prevena™ Incision Dressing circumferentially outweighs the risk of circulatory compromise, extreme care should be taken not to stretch or pull the dressing when securing it. Attach the dressing loosely and stabilize edges with an elastic wrap if necessary. It is crucial to systematically and recurrently palpate distal pulses and assess distal circulatory status. If circulatory compromise is suspected, discontinue therapy and remove dressing. • Electrodes or Conductive Gel: Do not allow the Prevena™ Incision Dressing to come in contact with EKG or other electrodes or conductive gels during electronic monitoring or when taking electronic measurements. • Dressing Components: The Prevena™ Incision Dressing contains ionic silver (0.019%). Application of products containing silver may cause temporary tissue discoloration. • Always use Prevena™ dressings and canisters from sterile packages that have not been opened or damaged. • All components of the Prevena™ Incision Management System are for single use only. Do not re-use any component of this system. • To avoid trauma to the skin, do not pull or stretch the adhesive border of the dressing during application. PREVENA™ INCISION MANAGEMENT SYSTEM DESCRIPTION The Prevena™ Incision Management System contains the following single use, disposable components (Fig. 1). All patient contact materials are free of latex and DEHP [Di(2-ethylhexyl)phthalate]. Fig. 1 Prevena™ Incision Management System

• Prevena™ Patch Strips - Used to help seal leaks around dressing. • Prevena™ 45mL Canister - A sterile reservoir for collection of wound fluids. • Prevena™ 125 Therapy Unit - Delivers negative pressure to the surgical area. The unit is battery powered. The Prevena™ Carrying Case is provided to facilitate patient mobility. DRESSING APPLICATION Site Preparation: 1. Prior to surgery, shave the surgical area where the dressing will be applied to improve dressing adhesion and seal integrity. 2. Gather all items needed for application: • Sterile wound cleaning solution, e.g. water, saline or alcohol. • Sterile gauze or other material to clean application site. • Prevena™ Incision Management System (Check expiration date on box). 3. Immediately post surgery, cleanse the application site with sterile gauze and sterile wound cleaning solution using a circular motion beginning at the center of the surgical area and extending outward to ensure that the site is free of foreign material. 4. Pat the application site dry with sterile gauze. To ensure proper adhesion, the application site must be completely dry before dressing is applied. Drain Tubes and Pain Management Control Devices: The Prevena™ Incision Management System can be used with both drain tubes and pain devices, provided the dressing is not placed over tubing where it exits the skin. Surgical drains must be routed under the skin beyond the boundary of the dressing and function independently of the Prevena™ Incision Management System. NOTE: While the concomitant use of surgical drains is allowable with the Prevena™ Incision Management System, the system must not be used as an outlet or reservoir for the drain. 2
Prevena™ Incision Management System Application: 1. Open the sterile dressing package and remove dressing and patch strips using aseptic technique. Do not use if package has been torn or the sterile seal has been compromised. Fig. 2 Top View of Dressing
2. Gently peel back the center strip on the back of the dressing exposing the pull tabs and adhesive (Fig. 3). Fig. 3 Bottom View of Dressing
3. Center and apply the dressing over the closed wound or incision ensuring that the adhesive will not contact or cover the surgical closure. Orient the dressing on the patient to eliminate sharp bends / kinks in the tubing. Remove the remaining bottom adhesive covers by grasping the bottom tabs and gently pulling (Fig. 4A). Firmly press around the dressing to ensure a good seal where the adhesive contacts the skin (Fig. 4B). Remove top stabilization layers (Fig. 4C). Fig. 4 Dressing Application
