A Prospective, Open-Label Study to Assess the Clinical Performance of a Foam Dressing in the Management of Chronic Wounds

Petra Zoellner, PhD; Holger Kapp, MS; and Hans Smola, MD


This study had a number of limitations. The number of patients was small and the descriptions of the wound surface and depth were based on approximations of the examining physicians and/or patients without additional confirmation from other professionals. Exudate amount also was estimated by the physicians; their subjective observations often are presented in percents as opposed to raw data. The observed reduction in the proportion of highly exudating wounds may have been attributed to the absorptive properties of the dressing, observed advancement of wounds along the healing continuum, or the effects of additional (secondary) dressings and concomitant therapies. In the absence of a control group or a larger sample size, the effects of each variable on the outcomes observed cannot be ascertained.


This non-randomized, non-comparative trial involving 57 outpatients with (mostly) nonhealing wounds provides interesting initial evidence about the clinical performance of a foam dressing. Wound state as well as periwound skin improved in the course of the study. These results suggest that the foam dressing is an appropriate choice for treating heavily to moderately exuding chronic wounds.

This study was sponsored by a grant from Paul Hartmann AG, Heidenheim, Germany.
