RESUMEN
OBJECTIVE: N-acetyl cysteine (NAC) is a thiol compound with antioxidant and vasodilatory properties. It has multiple potential uses-including as an aid to wound healing-supported by varying levels of evidence. Pressure ulcers (PUs) are a major problem affecting older and bed-bound patients, and are associated with significant morbidity, mortality, and health-care costs. We aimed to study whether topical NAC treatment may be useful in non-healing PUs in a prospective case study in two debilitated nursing home residents suffering from a total of three treatment-resistant PUs. METHOD: PUs were staged as described by the National Pressure Ulcer Advisory Panel. The ulcers were measured at the beginning and weekly thereafter with a standard wound measuring paper ruler. RESULTS: The first patient had a category 3 pressure ulcer and the second patient had one category 3 and one category 4 ulcer. Topical NAC vial administration significantly improved healing in all three PUs without any side effects. CONCLUSION: Our data indicate that NAC may be used in treatment-resistant PUs successfully.
