It is also virtually painless for the patient. Autolytic debridement can be achieved with the use of occlusive or semi-occlusive dressings which maintain wound fluid in contact with the necrotic tissue. Autolytic debridement can be achieved with hydrocolloids, hydrogels and transparent films. It is suitable for wounds where the amount of dead ...
In other words, though autolysis resembles the active process of digestion of nutrients by live cells, the dead cells are not actively digesting themselves as is often claimed, and as the synonym self-digestion suggests. Failure of respiration and subsequent failure of oxidative phosphorylation is the trigger of the autolytic process. [1]
Hydrogel dressing is a medical dressing based on hydrogels, three-dimensional hydrophilic structure. [1] The insoluble hydrophilic structures absorb polar wound exudates and allow oxygen diffusion at the wound bed to accelerate healing. [2]
The dressing delivers absorption or hydration as needed over each independent wound area and aids in the natural process of autolytic debridement. It effectively removes liquefied slough and necrotic tissue, disintegrated bacterial biofilm as well as harmful exudate components, known to slow the healing process. [ 41 ]
It also plays an additional role in autolytic debridement (removal of dead tissue) which is less painful when compared to manual wound debridement inside the operating theater. It is highly elastic and flexible, thus is closely adhered to the skin. As the dressing is transparent, wound inspection is possible without removing the dressing.
An open wound after debridement. Debridement is an essential element of effective wound care. [7] Although this view is deeply rooted in practice it is nonetheless based on empirical observation. Bradley et al. have stated that it is "unclear whether wound debridement is a beneficial process that expedites healing". [8]
