Silver Alginate Dressing 4" x 4.75" - Antimicrobial Calcium Alginate, Sterile Rectangle

Advanced Silver Alginate Wound Dressing with Antimicrobial Protection

This professional-grade calcium alginate dressing with integrated antimicrobial silver delivers superior wound management for moderate to heavily exudating wounds while providing broad-spectrum antimicrobial protection. Each sterile dressing contains 5% Silver Sodium Hydrogen Zirconium Phosphate by weight, offering sustained silver ion release that helps reduce bacterial colonization and supports optimal wound healing environments. The highly absorptive alginate fibers transform into a conformable gel upon contact with wound exudate, maintaining a moist wound environment while effectively managing drainage and helping control minor bleeding.

Dual-Action Wound Management: Absorption and Antimicrobial Protection

This advanced dressing combines the exceptional fluid-handling capabilities of calcium alginate with the proven antimicrobial properties of ionic silver technology. The alginate component rapidly absorbs moderate to heavy amounts of wound exudate—up to 20 times its weight in fluid—transforming from a dry fiber sheet into a soft, conformable gel that maintains intimate contact with the wound bed. This gel formation creates an optimal moist healing environment that supports autolytic debridement, promotes granulation tissue formation, and facilitates epithelialization. Simultaneously, the silver component provides continuous antimicrobial activity against a broad spectrum of wound pathogens including antibiotic-resistant organisms, helping reduce bioburden and minimize infection risk in compromised wounds.

Optimal Gelling Profile for Atraumatic Removal

Engineered with a precisely calibrated gelling profile, this alginate dressing achieves the ideal balance between fluid absorption and structural integrity. Upon absorbing wound exudate, the dressing forms a cohesive gel that conforms to wound contours and fills irregular wound spaces, yet maintains sufficient physical integrity to allow removal from the wound in one piece. This optimal gelling characteristic prevents the dressing from adhering to the wound bed or fragmenting during removal, minimizing trauma to newly formed granulation tissue and reducing patient discomfort during dressing changes. The non-adherent gel interface protects delicate healing tissue while simplifying the removal process for caregivers.

Versatile Application for Complex Wound Geometries

The flexible 4-inch by 4.75-inch (10.2 cm x 12.1 cm) rectangular sheet format accommodates a wide range of wound sizes and configurations. The dressing can be applied flat to cover shallow wounds, layered for deeper cavities, or cut and shaped to fit irregular wound dimensions. For wounds with depth or undermining, the alginate can be loosely packed into the wound space to fill dead space, absorb exudate from the wound base, and support healing from the inside out. The ability to trim the dressing to precise wound dimensions minimizes waste, reduces maceration of periwound skin, and ensures optimal coverage without excessive overlap onto healthy tissue.

Clinical and Practical Benefits

• 5% Antimicrobial Silver: Silver Sodium Hydrogen Zirconium Phosphate provides sustained silver ion release for broad-spectrum antimicrobial activity against bacteria, fungi, and antibiotic-resistant organisms
• High Absorbency: Calcium alginate fibers absorb moderate to heavy wound exudate, managing drainage effectively and reducing dressing change frequency
• Hemostatic Properties: May help control minor bleeding through calcium-sodium ion exchange that supports clot formation
• Optimal Gel Formation: Transforms into conformable gel that maintains contact with wound bed while preserving structural integrity for one-piece removal
• Non-Adherent: Gel interface prevents sticking to wound bed, minimizing trauma during dressing changes and protecting fragile granulation tissue
• Cavity Filling: Can be packed into wound cavities, tunnels, and undermined areas to fill dead space and absorb exudate from wound base
• Trimmable Design: May be cut to fit exact wound dimensions, reducing waste and preventing maceration of surrounding healthy skin
• Moist Wound Environment: Maintains optimal moisture balance that supports autolytic debridement and accelerates healing
• Sterile Packaging: Individually wrapped sterile dressing ensures aseptic application and reduces infection risk
• Latex-Free: Not made with natural rubber latex, safe for latex-sensitive patients and healthcare workers

Optimal for Multiple Wound Types and Clinical Settings

This versatile silver alginate dressing supports healing across diverse wound etiologies and care environments. Acute wounds including surgical incisions, traumatic lacerations, donor sites, and post-debridement wounds benefit from the combined absorption and antimicrobial protection. Chronic wounds such as diabetic foot ulcers, venous leg ulcers, pressure injuries, and arterial ulcers receive sustained silver antimicrobial activity to address bioburden concerns common in non-healing wounds. Partial and full-thickness wounds with moderate to heavy drainage achieve effective exudate management without frequent dressing changes. Wounds at risk for infection or with existing bacterial colonization benefit from the broad-spectrum antimicrobial coverage. The dressing is suitable for use in hospitals, wound care clinics, long-term care facilities, home health settings, and outpatient treatment centers.

Application and Use Guidelines

Before application, cleanse the wound according to facility protocol and assess wound dimensions, depth, and exudate level. Select appropriate dressing size or trim to fit wound dimensions, allowing minimal overlap onto periwound skin. For shallow wounds, apply the alginate sheet directly to the wound bed. For cavity wounds, loosely pack the alginate into the wound space without overpacking, which could impede drainage. Apply an appropriate secondary dressing such as foam, transparent film, or gauze to secure the alginate and protect the wound from external contamination. The secondary dressing also manages any strike-through and maintains the moist environment. Change the dressing when the secondary dressing becomes saturated, when strike-through occurs, or according to clinical assessment and facility protocols—typically every 1-7 days depending on exudate levels.

Hemostatic and Antimicrobial Mechanisms

The calcium alginate fibers facilitate hemostasis through ion exchange: calcium ions from the dressing are released in exchange for sodium ions from blood and wound fluid, supporting platelet aggregation and clot formation to help control minor bleeding. This property is particularly valuable for post-surgical wounds, traumatic injuries, and wounds following sharp debridement. The silver component provides antimicrobial protection through multiple mechanisms: silver ions disrupt bacterial cell walls, interfere with cellular respiration, and inhibit DNA replication. This multi-targeted approach reduces the likelihood of bacterial resistance development while providing effective activity against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE), and other problematic wound pathogens.

Quality and Safety

Manufactured to rigorous medical device standards, each dressing undergoes sterility validation and quality inspection to ensure consistent silver content, appropriate fiber structure, and freedom from defects. The controlled silver release profile provides sustained antimicrobial activity throughout the wear time without cytotoxicity to healing tissue. Single-use disposable design eliminates cross-contamination risks and ensures fresh antimicrobial protection for every application. Latex-free construction accommodates patients and healthcare workers with latex sensitivities. The non-occlusive design allows oxygen and moisture vapor transmission while the secondary dressing provides the barrier function, balancing wound protection with physiologic gas exchange.
