AB  - Aim: 
Hydroactive dressings mainly consist of alginate or carboxymethylcellulose fibers that can be processed to compresses or tamponade strips and exhibit high fluid uptake. Highly exuding wounds may lead to macerated wound edges and during gel formation, loss of shape might occur, which results in reduced wound coverage. Hence, fluid management of hydroactive dressings was analyzed using a special maceration model.

Methods: 
Two dressings with carboxymethylcellulose (A-B), one consisting of cellulose/ ethylsulfonatecellulose (C), and an alginate tamponade (D) were investigated. They were applied to an artificial wound in a tissue substitute for maceration-tests. Evaluation of fluid uptake and distribution in dressings was performed by video recording. Shape loss of dressings, maximal fluid uptake and time to maceration was determined.

Results: 
A and B exhibited a distinct shrinkage during fluid uptake with 29 and 36%.
C showed significantly higher form stability (18%shrinkage). For D, no loss of surface coverage was observed. D demonstrated the lowest fluid holding capacity (20mL fluid uptake). A similar fluid uptake till maceration break point was found for A. B and C exhibited significantly higher values with 25 and 30mL. Moreover, with A and B maceration already occurred before the dressings were completely soaked. Leakage with dressings C and D was only observed after they were gelled.

Conclusions: 
An in vitro maceration model was successfully used to quantify and evaluate the differences between hydroactive wound dressings. This model is hence suitable to analyse fluid management in an in vivo like situation.
