Hemostatic Dressing 4" x 4"

Key Specifications

Product Overview

The Dynarex Hemostatic Dressing is a chitosan-impregnated gauze pad in the standard 4 in. × 4 in. format familiar to any first aid or medical provider. It provides accessible, cost-effective hemostatic capability for civilian and public-access contexts — schools, workplaces, gyms, vehicles, and community first aid kits — where the price point of clinical hemostatic agents like QuikClot Combat Gauze, Celox RAPID, or ChitoGAUZE XR PRO may be prohibitive for broad distribution. At roughly a fraction of the cost of military-grade hemostatic dressings, the Dynarex 4 in. × 4 in. allows organizations to equip more locations and more individuals with hemostatic capability than would be possible with premium products alone.

The chitosan mechanism provides surface wound hemostasis through the same muco-adhesive interaction used by Celox, ChitoGAUZE, and ChitoSAM products — positively charged chitosan binds to negatively charged red blood cell membranes, promoting local aggregation and clot formation. The 4 in. × 4 in. pad format is designed for surface coverage applications, not deep wound packing. It is appropriate for lacerations, minor to moderate bleeding wounds, and surface hemorrhage management in first aid contexts. It is not designed for, and should not be used in lieu of, wound packing with a full-length hemostatic gauze for arterial or severe penetrating trauma.

For organizations building layered bleeding control programs — placing initial responder-accessible kits throughout a facility while reserving higher-capability products for trained personnel — the Dynarex 4 in. × 4 in. provides a practical entry-level hemostatic for bystander and first responder use. It serves as a lower-cost alternative to QuikClot dressings (as noted in the product's own description) for situations where premium hemostatic gauze is not required or not justified by budget constraints. For critical or severe traumatic hemorrhage, users should be escalated to CoTCCC-recommended hemostatic agents and trained responders.

How to Apply

1. Expose the wound and apply the 4 in. × 4 in. pad directly over the bleeding site.
2. Apply firm, direct manual pressure through the pad for 3–5 minutes without lifting to check.
3. Secure with a bandage or tape to maintain pressure and keep the pad in contact with the wound.
4. If bleeding soaks through, apply additional pads on top — do not remove the first pad, as this can disturb the forming clot.
5. For serious injuries, call 911 immediately and continue pressure until professional care arrives.
6. Remove at definitive care or when wound is cleaned and closed.

When to Choose a Clinical-Grade Hemostatic Instead

For serious, life-threatening hemorrhage — arterial bleeding, gunshot wounds, deep penetrating trauma, junctional wounds — the Dynarex 4 in. × 4 in. pad should be replaced with a full-length hemostatic gauze from MED-TAC's clinical product line. The CoTCCC-recommended QuikClot Combat Gauze (3 in. × 4 yd., Z-fold), Celox RAPID, or ChitoGAUZE XR2 PRO provide the wound packing length and hemostatic concentration required to pack and control arterial hemorrhage. The Dynarex 4 in. × 4 in. is not a substitute for these products in life-threatening trauma.

For complete hemorrhage control systems, explore MED-TAC's full hemostatic agents collection, massive hemorrhage control kits, and public access bleeding control kits.
