Leg venous ulcer healing process after application of membranous dressing with silver ions

Summary

Aim: To assess the efficiency of application of new membranous dressing with silver ions in patients with chronic venous ulceration.

Methods: 58 patients were divided randomly into two groups. In group A (n=30) mean ulcer surface area was 8.52 cm², in group B (n=28) mean wound surface area was 8.29 cm². In group A membranous dressings with silver ions (Textus Bioactiv^® by Biocell GmbH, Germany) were used. In group B hydrocolloid dressing Unna’s boot was applied. All dressings were changed every 7 days until the wound was completely healed. Changes in wound area were calculated and the speed of healing process was measured every week with healing per day index (cm²/day).

Results: After 7 weeks ulcers healed in all patients of group A. Ulcers in group B healed after 16 weeks of treatment.

Conclusion: On the basis of this outcome the authors concluded that application of membranous dressing with silver ions speeds up the process of treating chronic lower leg ulceration.

Zusammenfassung

Ziel der Studie: Die Effektivität der Applikation einer neuen Wundauflage mit Silberionen wurde an Patienten mit chronischer Beinulze-ration getestet.

Methode: 58 Patienten wurden zufällig in zwei Gruppen geteilt. Bei Gruppe A (n=30) betrug die durchschnittliche Ulkusfläche 8,52 cm², in Gruppe B (n=28) durchschnittlich 8,29 cm². Die Patienten der Gruppe A wurden mit einer Silberionen-haltigen Wundauflage versorgt (Textus Bioactiv^® Biocell GmbH, Deutschland). Gruppe B wurde mit einer Hydrokolloid-Auflage (Unna’s boot) versorgt. Alle Auflagen wurden 1-mal pro Woche gewechselt bis die Wunde verheilt war. Die Veränderungen der Wundfläche wurden wöchentlich berechnet, ebenso die Geschwindigkeit des Heilungsprozesses (cm²/Tag).

Ergebnisse: Ulzera in Gruppe A waren nach 7 Wochen Behandlung geheilt, in Gruppe B nach 16 Wochen.

Schlussfolgerung: Auf der Basis dieser Ergebnisse schlussfolgern die Autoren, dass die Auflagen mit Silberionen den Heilungsprozess chronischer Beinulzera beschleunigen.
