One of the most common challenges in hemodialysis and PICC line maintenance is managing 

Standard sterile gauze is the traditional solution, but it comes with a major flaw: it adheres to the clotting wound. When the gauze is removed, it often rips the newly formed clot, causing "secondary bleeding" and pain.

 is the superior standard. Here is the science behind why our 

 works and the step-by-step guide on how to use it effectively.

Why does alginate stop bleeding faster than cotton gauze? It’s not just absorption; it’s chemistry.

 comes into contact with blood (which contains Sodium ions), a rapid ion exchange occurs:

 from the blood enter the dressing fibers.

 from the dressing are released into the wound.

 Calcium is a "Factor IV" in the body’s natural coagulation cascade. By flooding the wound site with calcium, the dressing actively accelerates the formation of a fibrin clot, reducing hemostasis time by up to 

Unlike gauze, which remains fibrous and dry, our Alginate Wound Dressing fibers absorb fluid and transform into a 

This gel creates a moist seal over the puncture point. Most importantly, 

. When it’s time to remove the dressing, it slides off painlessly, leaving the clot perfectly intact.

Follow this protocol for Dialysis Fistulas, PICC lines, or IV cannulation sites.

Clean the puncture site with iodine or chlorhexidine according to your facility’s standard protocol. Ensure the surrounding skin is dry to allow the adhesive to stick.

For small puncture points, you do not need a large sheet.

. You can use our standard flat pad size. Fold it once if needed to increase density.

Apply manual pressure (or use a tourniquet/strap) over the dressing.

 Hold for 2–5 minutes (depending on the patient's coagulation status).

 Because the alginate actively aids clotting, you will often find that less compression time is needed compared to gauze.

Once bleeding has slowed to a seep, cover the alginate pad with a secondary fixation layer if necessary, or simply inspect the site. The gel formation will indicate absorption is working.

Clinical Pearl: The Non-Adherent Interface

The primary failure point in puncture care is

 transforms into a gel that creates a "non-adherent interface." This allows nurses to remove the dressing without disturbing the newly formed clot.
