Today’s Technology to Keep Access Sites Dry and Intact

1. Today’s Technology to Keep Access Sites Dry and Intact

2. The Challenge A major source of catheter-related infection is soiled, wet or loose dressings caused by bleeding or oozing at insertion sites and/or diaphoresis. The Centers for Disease Control (CDC) Guidelines for Prevention of Intravascular Catheter-Related Infectionsinclude recommendations to: • Replace catheter-site dressing if the dressing becomes damp, loosened, or visibly soiled; therefore, keep catheter site dry and intact. • Replace dressings used on short-term CVC sites every 2 days for gauze dressings and at least every 7 days for transparent dressings.

3. The Solution: BioSeal CVC Powder The ingredients are a mixture of a hydrophilic polymer and a potassium ferrate. BioSeal CVC Powder is not a vasoconstrictor, or a cauterizing agent. It is non-systemic, non-toxic and it is not biologically derived. BioSeal CVC Powder, formerly PRO QR Powder, is a topical powder that forms an occlusive seal to stop the flow of blood and exudates and keep microbes from entering the site. 3

4. Proven Efficacy Results from a product trial** of BioSeal CVC (PRO QR) usage for 418 PICC lines at a large Florida hospital: **Trial results on file at Biolife. 4

5. How Does the Powder Work? The mechanism of action is a simultaneous two-step action whereby the hydrophilic polymer rapidly dehydrates the blood and absorbs exudates while the potassium ferrate binds with the blood proteins to create an occlusive seal. As the blood becomes dehydrated, the “nothing in, nothing out” seal thickens until blood and nutrient-rich exudates can no longer permeate through the seal. The seal creates a hostile barrier to microbes on the distal side, while maintaining a neutral environment on the proximal side.

6. The Difference is the Seal Seal Extra powder • The seal: • Allows “nothing in/nothing out” • Keeps sites dry and intact • Minimizes complications from bleeding/exudate leakage • Eliminates unnecessary dressing changes • Fits all sizes of lines or tubes • Increases patient satisfaction SEM photography of a 5 Fr.

7. BioSeal Creates a Sustained Hostile Environment • Above the Seal • Bacteria, full of water and salts, come in contact with the BioSeal CVC powder on the top side of the seal. (H20 & Ca++, Na+, K+) • The bacteria dries (desiccation) • The moisture pulled from the bacteria contain salts. The cations of these salts are exchanged for H+ (acidic), creating a low pH environment (~2) above the seal. • The Seal • Composed of coagulated blood components • Below the seal the pH is ~ neutral • Above the seal the pH is ~ 2 • Below the Seal • The BioSeal CVC Powder floats on the blood, therefore it doesn’t penetrate the seal. This results in a neutral pH below the seal. (The pH below the seal was measured @ 7.4 in a saline extraction of a laboratory-created seal.) 7

8. Key Applications Use BioSeal CVC Powder with the following devices to stop bleeding and oozing and protect the site: Vascular Devices: (insertions and removal) PICCs/Midlines Central Venous Catheters Dialysis Catheters Arterial Catheters (maintenance) Also effective in controlling bleeding and exudate leakage from Non-Vascular Devicessuch as: Peritoneal dialysis catheters Epidural catheters Large-bore needles used for paracentesis, thoracentesis, or biopsies PEG/Gastrostomy feeding tubes Photo by Penny Offer, CRNI 8

9. BioSeal CVC Application – Tips for Success Do’s: • To ensure success, secure the line with securement device before applying powder • Apply firm pressure for two minutes directly over wound with dry, gloved fingers or non-adherent dressing to form the protective seal and achieve hemostasis. • Roll fingers off of site to release pressure • Leave seal over wound; the “BioSeal” will fall off naturally on its own, or if needed, may be removed with sterile technique. Don’ts: • Do not hold pressure over BioSeal powder with gauze to avoid tearing the seal (use dry, gloved fingers instead). • Do not check for hemostasis before the recommended holding time complete. This could disturb the strengthening seal. Pour Powder Hold Pressure Seal is formed Photos by Penny Offer, CRNI
