Objective: To compare the effectiveness of polyvinylidene (PVL) food wrap as a dressing material versus conventional ointments and gauze dressings for pressure ulcers in patients aged 60 years or over.
Methods: A prospective open controlled trial was conducted. The severity of pressure ulcers in both groups was evaluated using the DESIGN system. Scores were compared at baseline, four, eight and 12 weeks.
Results: Twenty-five patients were treated with the PVL film (test) dressings and 24 with the conventional treatment (control). The test group showed greater improvement in DESIGN scores than the control group throughout the observation period, and the difference reached statistical significance at 12 weeks (p < 0.05). The incidences of local wound infection in the two groups were not statistically different (p > 0.999).
Conclusion: The PVL film dressing was more effective than conventional treatment in the management of severe pressure ulcers.
