Effects of Topical Negative Pressure Treatment on Grade III and IV. Pressure Ulcers

Abstract

Objective:This study was conducted as a quasi-experimental research to determine the effect of Topical Negative Pressure Treatment on healing of Grade III and IV pressure ulcers. Method: The sample consisted of 14 pressure ulcers in seven patients at one university and two state hospitals in Ankara, Turkey. The data was collected through Patient Data Form prepared by the researcher including sociodemographic information and contributing factors for pressure ulcer development, Pressure Ulcer Healing Chart for pressure ulcer assessment, and Wong-Baker Pain Scale for procedure related pain assessment. Means, standard deviations, and percentages, Wilcoxon Signed Pair Ranks Tests, McNemar and Friedman Tests were used for analysis. Results: At the end of eight Topical Negative Pressure Treatments 2 weeks , pressure wound surface area was reduced in nine of Grade III and IV pressure ulcers compared to initial measurements. No change in tissue appearance was observed in six ulcers, reduction was detected in pressure wound depth in ten ulcers, and necrotic tissue initially present at the wound area reduced in eleven ulcers. The difference between the first and last session mean scores of surface area, exudate amount, and wound depth was statistically significant p

Topikal Negatif Basınç Terapisinin III. ve IV. Evre Basınç Yaralarının İyileşmesine Etkisi

Abstract

Amaç: Bu çalışma, basınç yaralarının bakımında kullanılan Topikal Negatif Basınç Terapisi'nin III. ve IV. evre basınç yaralarının iyileşmesi üzerine etkisini değerlendirmek amacıyla yarı deneysel olarak yapılmıştır. Yöntem: Çalışma, Ankara’daki bir üniversite ve iki devlet hastanesi olmak üzere üç hastanede toplam yedi hastadaki 14 III. ve IV. evre basınç yarası ile gerçekleştirilmiştir. Çalışmada veriler, araştırmacı tarafından hazırlanan ve hastaların sosyo-demografik bilgileri ve basınç yarası gelişimini etkileyebilecek özellikleri içeren Tanıtıcı Bilgiler Formu, basınç yaralarının değerlendirilmesi için Basınç Yarası İyileşme İzlem Çizelgesi ve hastaların işleme bağlı ağrı düzeylerini belirlemek amacıyla Wong-Baker Ağrı Skalası aracılığı ile toplanmıştır. Verilerin analizinde, ortalama, standart sapma, yüzdelik, Wilcoxon eşleştirilmiş iki örnek testi, McNemar ve Friedman testlerinden yararlanılmıştır. Bulgular: Araştırmada yara üzerine uygulanan sekiz Topikal Negatif Basınç Terapisi sonunda iki hafta III. ve IV. evre basınç yaralarının dokuzunda yara alanında başlangıç ölçümüne göre küçülme görülmüştür. Altı yarada doku tipinde bir değişme görülmemiş, 10 yarada yara derinliğinde azalma saptanmış ve 11 yarada başlangıçta yara bölgesinde var olan nekrotik dokuda azalma belirlenmiştir. Alan, eksuda ve derinlik değişkenleri, başlangıç ve bitiş puan ortalamaları arasındaki fark istatistiksel olarak anlamlı bulunmuştur p
