The effect of Negative Pressure Wound Therapy versus Hydrocolloid Dressing on the Healing Rate of Stage III and IV Pressure Ulcers


Pressure ulcer is a change or break in the skin caused by constant pressure. Appropriate care and treatment method selection play a key role in promoting and maintaining a wound environment that is conducive to healing. The aim of this study is to compare the effect of negative pressure wound therapy (NPWT) versus hydrocolloid dressing on the rate of healing of stage III and IV pressure ulcers. This study is of a Quasi experimental research design. It was conducted on 60 patients with pressure ulcers; 30 treated with NPWT and 30 with hydrocolloid dressing in the medical surgical units at Monla Hospital, Tripoli, Lebanon. The Pressure Ulcer Scale for Healing (PUSH) was adopted. The tool included “Patient‟s Profile”, “Pressure Ulcer Assessment, and “Pressure Ulcer Healing Graph”. METHODS: an official permission to conduct this study was obtained. Application of the treatment and assessment was done every 3 days per week for 1 month over a period of 9 months. RESULTS: revealed that in all PUSH parameters, the surface area, exudates amount, tissue type, and the total PUSH score, the mean variation was better in the NPWT with statistical significance. CONCLUSION: NPWT had better outcome than HC in reducing pressure ulcer surface area, managing exudates, initiating the formation of granulation tissue, and enhancing overall wound healing. RECOMMENDATIONS: Replicate the present study on a larger group, time, and in different locations. Conduct a study on the predictive value with the same pressure ulcer healing scale.
