Pressure Ulcer Care Products: Foam, Silicone and Hydrofiber Selection Guide

The Importance of Material for Pressure Ulcer Care Products

Pressure ulcers are considered chronic and result from repeated stress upon an area of the skin. They often form in areas subjected to repetitive mechanical stress, i.e., the sacral area, heel, hip, and other bony prominences.

Healthcare professionals should not base their choice of Pressure Ulcer Care Products on the least absorbent dressing. The structural integrity of the dressing is essential in helping to manage the wound by:

•Restricting exudate

•Maintaining an optimum moisture environment

•Preserving trauma free skin barrier

•Lessening the trauma to the patient during prolonged treatment

Modern day Wound Care incorporates three main materials, i.e., silicone, foam and hydrofiber. The specific materials rely on the wound pathology, the exudate type and the skin of the patient to determine the optimum materials for the job.

Why Materials Define the Effectiveness of Pressure Ulcer Care Products

A pressure ulcer wound exudate has specific components such as water, proteins, electrolytes, and inflammatory molecules. The presence of excess fluids around the open wound site has negative consequences such as:

•Infection risk

•Maintaining periwound integrity

•Slow healing

•More intervention

Too rapid removal of fluids negatively impacts healing as well. Hence, the advanced Pressure Ulcer Care Products should be able to balance the levels of fluids present instead of just desiccating the surface.

A high-performance dressing uses a unique combination of:

•Absorption capacity

•Fluid retention under pressure

•Moisture vapor transmission

•Mechanical protection

•Skin-friendly adhesion

Research into foam dressings has indicated that all of these elements impact the dressing's ability to control leakage. Absorption is not the only factor that influences how long a dressing will remain in place.

Foam-Based Pressure Ulcer Care Products: Absorption and Cushioning Protection

How Polyurethane Foam Adjusts to Wound Exudate

Foams are an excellent choice for protection in Pressure Ulcer Care Products due to their capability of absorbing quickly while providing cushioning to vulnerable areas of the wound.

Foam has structures designed to:

•Absorb fluids from an open wound surface utilizing capillary action

•Provide internal volume to store fluids

•Cushion and absorb impact from external forces

Foam dressings are unlike other absorbent materials. Unlike simple absorbent materials, medical foam dressings are manufactured as multi-layer systems designed with different functions.

Foam Layer	Function in Pressure Ulcer Care Products
Contact layer	Removal of dressing causes least trauma to patient
Absorbent foam core	Captures and distributes wound fluid
Retention layer	Reduces fluid leakage under compression
Protective film	Controls moisture vapor exchange

Technical Parameter	Greetmed Foam Dressing Specification Clinical Value
Material Structure	Medical polyurethane foam Supported cushioning and flexibility
Thickness Range	2–6 mm Balanced cushioning and flexibility
Foam Density	Approx. 735 g/m² (5 mm thickness) Provided stable foam structure
Absorbent Performance	6.49 g/10 cm²/24h at 37°C Manages continuous wound exudate
Total Absorbent Capacity	8.78 g/10 cm²/24h at 37°C Ideal for moderate to heavy exudate wounds

Greetmed's Pressure Ulcer Care Products are based on medical polyurethane foam structures designed to control exudate. This type of foam dressing technology is designed to manage exudate with a combination of controlled thickness, density, and absorbent performance.

These specific components provide foam dressings with the ability to control fluids and simultaneously provide a cushioning protective layer, which is needed for sensitive pressure areas in the anatomy.

A Review of the Use of Silicone Technology in Pressure Ulcer Treatment Products: Protection of Fragile Skin During Long Term Treatment

Pressure ulcer patients repeatedly need their dressing changed. Aggressive adhesive-based dressings cause stripping of the skin in the elderly and fragile-skin patients.

The use of silicone technology in dressing adhesives results in non-adhesive contact and minimizes the amount of dressing adhesives in contact with the skin.

Use of Silicone Technology in Pressure Ulcer Treatment Products

Key Benefits of Silicone-Based Structures

Silicone components in Pressure Ulcer Care Products are designed to provide:

•Lower-trauma removal

•Reduced skin irritation risk

•Better patient comfort

•Improved dressing repositioning ability

Silicone is not primarily an absorption material. Instead, it improves the interaction between the dressing and the patient's skin, making it especially suitable for long-term wound management where skin preservation is critical.

Hydrofiber Pressure Ulcer Care Products: A Different Approach to Heavy Exudate Control

Hydrofiber materials manage wound fluid through a different mechanism compared with foam.

Exposure to exudate gives hydrophilic fibers the capacity to absorb liquids and form a soft gel framework. This process helps:

•Lock Fluid Inside the Dressing

•Reduce Horizontal Spreading

•Create Close Contact with the Wound Surface

•Maintain Moisture Balance

For wounds that exude excessive quantities of liquid, gel formation from hydrophilic fibers prevents uncontrolled loss of excess liquid.

Hydrofiber, unlike foam, offers very little cushioning. Thus, if the challenge is primarily control of excessive liquid, hydrofiber should be selected over foam.

However, if the challenge is primarily control of liquid and mechanisms for cushioning, then foam should be selected over hydrofiber.

The selection of best Pressure Ulcer Care Products is predominantly based on the characteristics of the wound, regardless of what is most highly valued from the perspective of materials.

Technical Comparison of Pressure Ulcer Care Products Materials

Foam Dressing vs Hydrofiber Dressing

Material Property	Foam Dressing	Hydrofiber Dressing
Liquid management	Absorbs and retains liquid in foam structure	Absorbs and transforms liquid into gel
Cushioning	Excellent	Limited
Pressure protection	Stronger	Moderate

Standard Adhesive vs Silicone Adhesive

Material Property	Standard Adhesive	Silicone Adhesive
Fixation strength	Initial strong adhesion	Gradual low adhesion
Skin protection	Prevails over	Suitable for damaged skin
Adhesive removal	Injury risk	Low stress

Important Criteria for Assessing Pressure Ulcer Care Devices

Total performance evaluation is necessary as against assessing individual elements.

Absorption Capacity

The amount of fluid a dressing can accommodate.

Fluid Retention

The ability of a dressing to retain absorbed fluid when pressure is applied from the exterior.

Moisture Vapor Transmission Rate (MVTR)

The ability a dressing contains to control the evaporation of moisture through its outermost layer. An ideal MVTR prevents the dressing from retaining excessive moisture while maintaining proper levels of moisture to prevent wound dehydration.

Thickness and Density

The ability of a dressing to absorb moisture, achieve the required level of thickness, and maintain a balance between comfort and flexibility for the patient.

Greetmed's foam dressing utilizes foam structure and moisture management design to allow the dressing the ability to achieve a tested moisture permeability of 1.84 g/10 cm²/24h at 37°C to allow control of moisture during the healing process of wound dressings.
