Negative pressure wound therapy in patients with diabetic foot

View through CrossRef
Abstract Objective: In this study our aim was to compare the results of standard dressing treatment to negative pressure wound therapy (NPWT) performed with a vacuum-assisted closure (VAC) device in patients with diabetic foot ulcers. \r\nMethods: We assessed the results of 35 patients treated for diabetic foot ulcer between 2006 and 2008. Of these cases, 20 (4 women and 16 men; mean age: 66 years; range: 52-90 years) were treated with standard wet dressings and 16 feet in 15 patients (10 men, 5 women; mean age: 58.9 years; range: 42-83 years) with VAC therapy. The success of treatment was evaluated in terms of hospitalization length and rate of limb salvation. \r\nResults: The average hospitalization period with VAC treatment was 32 days compared to 59 days with standard dressing treatment. All patients treated with standard dressings eventually had to undergo amputation. However, the amputation rate was 37% in the VAC treated group and 88% of patients had a functional extremity at the end of treatment. \r\nConclusion: VAC therapy, together with debridement and appropriate antibiotic therapy, enables a higher rate of limb salvage, especially in Wagner Grade 3 and Grade 4 ulcers. Özet Amaç: Çalışmamızda diyabetik ayak olgularında görülen yaraların tedavisinde vakum destekli kapama (vacuum-assisted closure; VAC) cihazı kullanılarak gerçekleştirilen negatif basınçlı yara kapama ile standart pansuman tedavisinin sonuçlarını karşılaştırmayı amaçladık. \r\nÇalışma planı: 2006 ila 2008 yılları arasında diyabetik ayak yaraları tedavi edilen 35 hastanın sonuçlarını değerlendirdik. Olguların 20’sine (4 kadın, 1 erkek; ortalama yaş: 66; dağılım: 52-90) standart pansuman, 15 olgunun (10 erkek, 5 kadın; ortalama yaş: 58.9; dağılım: 42-83) 16 ayağına ise VAC tedavisi uygulanmıştı. Hastaların hastanede yatma süreleri ve uzuv kaybı oranları üzerinden tedavideki başarı değerlendirildi. \r\nBulgular: Hastanede yatış süresi VAC tedavisi gerçekleştirilen hastalarda 32 gün iken, standart pansuman tedavisi gören hastalarda 59 gün idi. Standart pansuman tedavisi gören olguların tamamında ampütasyon yapılmış iken, VAC ile tedavi edilen olgularda bu oran %37’ye düşmüştü. Yine, VAC tedavisi uygulanan hastaların %88’inde ekstremitenin korunması mümkün oldu. \r\nÇıkarımlar: Negatif basınçlı yara kapama Wagner sınıflamasına göre özellikle 3. derece ile 4. derece olgularda debridman ve uygun antibiyotik tedavisi ile birlikte ekstremitenin korunmasında daha yüksek başarı sağlamaktadır.
