Bioresorbable Nasal Dressings for Improved Wound Healing

Table of Contents

What Makes Nasal Dressings Essential for Clinical Surgery?

Nasal dressings are essential in post-surgical care to manage bleeding, support wound healing, and prevent adhesions. They provide a stable environment for the surgical site, facilitating quicker recovery and reducing the risk of complications.

Traditional nasal dressings often cause discomfort during removal, may not effectively manage exudates, and can increase the risk of infection if not properly designed.

How to Choose the Right Dressings for Nasal Surgery?

Unlike non-absorbable nasal dressings, absorbable options do not require manual removal, minimizing patient discomfort and reducing the risk of rebleeding. Additionally, the soft and comfortable material of absorbable dressings ensures better post-packing comfort, making them a superior choice for post-surgical care.

☛ Bioresorbable Nasal Dressings for Improved Wound Healing

What Are the Key Factors in Selecting Absorbable Nasal Dressings?

1. Wound Healing Effectiveness

Absorbability: The ability of the dressing to absorb wound exudate is crucial for effective management of discharge and prevention of infection. Absorbable nasal dressings, such as those made with bioresorbable materials, eliminate the need for manual removal, thereby simplifying the clinical procedure and reducing the risk of disrupting the healing tissue.
Structural Stability: The dressing should maintain its structural integrity throughout the healing process, typically for 7-10 days. This stability ensures effective support and management of the wound, avoiding premature disintegration that could compromise the healing process.

2. Immediate Hemostasis Effectiveness

Rapid hemostasis: Materials like collagen in absorbable nasal dressings induce platelet aggregation and fibrin release, promoting quick blood clotting and minimizing bleeding. This immediate hemostasis effect ensures better control of post-surgical bleeding and faster stabilization of the surgical site.

3. Patient Comfort

Biocompatibility: High biocompatibility is essential for minimizing irritation and promoting natural healing. Materials like collagen and carboxymethyl cellulose (CMC) are well-tolerated by the body, ensuring that the dressing integrates smoothly with the nasal tissues without causing significant inflammatory responses.
Self-Disintegration: Dressings that self-disintegrate, such as those made from bioresorbable materials, reduce the discomfort associated with removal. This feature is particularly beneficial for patient comfort, as it minimizes the need for manual intervention and the associated pain. Self-disintegrating dressings provide a more comfortable healing process and reduce the psychological burden on patients.

NasoAid – A Superior Nasal Dressing Solution

To overcome the clinical challenges of nasal operations, MBI has developed an exclusive Collagen+CMC composite technology for nasal dressing. This innovative technology makes NasoAid stand out from traditional non-degradable or single-component disintegrating materials by offering excellent self-disintegration and dual hemostasis. It is suitable for use in nasal/sinus operations and can be placed inside the nasal cavity as an intranasal splint to reduce bleeding and oedema, and to prevent adhesion of the nasal cavity to the septum.

1. Dual Hemostasis Mechanism

70% Collagen-Based Material: High porosity structure that promotes hemostasis by inducing platelets to release fibrin, crucial for rapid blood clotting and effective wound healing.
30% Carboxymethyl Cellulose (CMC): Attracts platelet aggregation and enhances hemostasis while providing additional benefits like moisturization and structural disintegration.

2. High Absorption Capacity& Support Strength

0.5mm Giant Hole Structure: Allows NasoAid to absorb up to 35 times its weight in liquid. This high absorption rate helps stabilize blood absorption and reduces the risk of rebleeding after surgery.
Full Recovery in 30 Seconds: NasoAid can be fully rehydrated back to its original volume within 30 seconds, providing immediate support and stability.
Long-lasting Structure: The structure of NasoAid Nasal Dressing can be maintained for 7-14 days after implantation, gradually disintegrating to minimize discomfort during removal.

3. Patient Comfort and Safety

Self-Fragmentation: Within 24 hours of implantation, NasoAid begins to form fragments on its own, minimizing discomfort and pain during removal. This feature is particularly beneficial for patient comfort and ease of care.
Excellent Biocompatibility: NasoAid Nasal Dressing complies with ISO 10993, ensuring excellent biocompatibility, which is crucial for patient safety and effective healing.
