How to care for cavity wounds?

Cavity wounds are a common clinical problem, and their management requires precise packing techniques and appropriate dressing selection. The following will discuss the packing techniques and dressing selection of cavity wounds and how these factors affect the wound-healing process.

The management of cavity wounds is a complex process involving multiple factors, including patient-related factors, wound-related factors, and the knowledge and skills of the healthcare provider. Historically, cavity wounds were packed with gauze strips, but the modern concept has shifted to loose packing to reduce trauma to the wound and promote healing.

when filling cavity wound pressure?

The packing material should be loosely spread over the entire wound bed, including the undertow, and avoid packing too tightly to prevent wound growth. The packing should be gentle to avoid damaging the newly formed granulation tissue and ensure that all "dead space" is eliminated to promote healing from the wound base.

What kind of dressing is suitable for this type of wound?

Accurate assessment of the wound and the patient helps determine the appropriate dressing for managing exudate. For wounds with moderate to severe exudation, gelling fiber dressings such as CMC hydrophilic fiber or polyvinyl alcohol fiber dressings are ideal packing dressings because of their good absorption and water holding capacity, ability to lock water and transfer liquids, which can effectively eliminate dead space and prevent surrounding skin from being soaked, maintain a moist environment and promote wound healing. Although alginate dressings have good liquid absorption capacity, they are relatively loose in structure and prone to residual fibers, making them unsuitable for packing small and deep wounds or sinuses.

Dressing Synergy :

Primary and secondary dressings should work together to create an ideal moist wound environment. For cavity wounds, gelling fiber dressings can be used to loosely pack the wound cavity to promote granulation tissue growth from the base and effectively manage undermining. In addition, an appropriate secondary dressing is needed to further help manage exudate.

What should we pay attention to when changing the dressing of this type of wound?

When changing the dressing, it should be ensured that the wound is not damaged, and the choice of packing material and the frequency of dressing changes should be determined by the nature of the wound, the cause, and the available dressing materials. The wound should be fully assessed and recorded in detail every time the dressing is changed, including the size, shape, and depth of the wound; the type of cavity such as sinus or channel; the tissue of the wound bed; the characteristics of the exudate; signs of infection, etc.

The management of cavity wounds requires comprehensive consideration of packing techniques and dressing selection. Loose packing and appropriate dressing selection are essential to promote wound healing, reduce infection risk, and improve patient comfort. Medical staff should choose the appropriate packing materials and dressings based on the specific conditions of the wound and individual differences of the patient to achieve the treatment effect.
