Clinical Trial Summary

In plastic and reconstructive surgery, treatment strategies of second-degree burn wounds and split-skin grafted third-degree burn wounds aim at reducing infection and improving reepithelialization. Although previous studies indicate that burn patients benefit from newer wound dressings, only a few studies comparing different wound dressings can be found. Therefore, the aim of this study is to evaluate time to reepithelialization, pain, microbiology, handling and costs of different wound dressings in patients with split-skin grafted third-degree burn wounds.

Description:

In the treatment of burn wounds polyhexanide and betaisodona (PVP-Iod) are regularly used today. They act as antiseptics, but both have drawbacks. Polyhexanide evaporates fast and therefore cools patients when applied to a large wound area. Moreover, it is known to reveal a gap for pseudomonas. On the other hand, the half-life of Betaisodona (PVP-Iod) ranges between several minutes and 12 hours. Further, its application causes intense pain, and it is cytotoxic. Other wound dressings involving silver are frequently used, too. However, they color the wounds, which might therefore not be properly assessed. Silver is also thought to be cytotoxic.

New innovations are available today. In wound dressings with bound Silver ions wounds are not colored. Hydrolytic membranes keep the level of acidity low (acidic) and have therefore antiseptic effects that last until epithelialization of a second-degree burn wounds is completed. Medical honey is used in the treatment of chronic wounds and especially in pediatric surgery and oncology. Manuka honey from New Zealand is sterilized before application and is known to be less painful for the patient. Due to its acidic effect, it reduces germ numbers in the wounds. Honey can be left on the wound for more than one day, as well as hydrogel, that is also used for contaminated wounds.

These new wound dressings are just used in a couple of Burn Units for the treatment of second-degree burns or split-skin grafted burns. However, the treatment of large burn wounds with older dressing regimes (e.g. PVP-Iod) cause intensive pain in every dressing change.

Only a few studies pointing at new dressings in burn wounds can be found in the literature. None of them reveals a high quality randomized trial.

The objective of this clinical investigation is a direct comparison of established and newer wound dressings with respect to epithelialization time, pain and the number of pathogenic microbe species. Besides, handling and cost are analyzed.

This is a prospective, randomised, factorial, open clinical study. Endpoint assessment, primarily the time to epithelialization, for direct comparison of the dressings is performed in a blinded way. The aim of this study is to identify the advantages of each dressing.

Every wound dressing will be used in every patient. The order from proximal to distal is varied so that every dressing is at every position in a balanced number of cases and has the same neighbor dressing in a balanced number of cases (Williams-Design). The order is assigned by randomisation. All comparisons of two wound dressing can be made using the same number of paired observations.

Assessors of epithelialization time and germ burden are blinded to the wound dressing used.
