Objective: There is a lack of literature on the characteristics and properties of fibre dressings available on the market. This study analysed the structure and absorption properties of different fibrous dressings used in wound treatment.
Method: This in vitro experiment was performed using scanning electron microscopy (SEM) and absorption test. Dressings were compared before and after the gelling process which was then compared with the results of the absorption test.
Results: A total of five samples were analysed. The SEM analysis demonstrated that there are differences in the gelling processes for each. In some cases, a formation of dead spaces was noticed. Despite a similar structure and mode of action, the dressings have different properties. Results were correlated with absorption measurements. There was a considerable difference in absorption capacity of individual dressings, which may further affect the capacity of the dressing to manage exudate.
Conclusion: Absorption of excess exudate and maintaining moisture balance in the wound environment are among the most important conditions of successful healing. Various fibrous dressings have different properties and clinicians should use this information to select the most appropriate dressing for the type of wound.
