A study to compare the effect of topical phenytoin dressing and conventional saline dressing in chronic non-healing ulcers
Keywords:Topical phenytoin dressing, Conventional saline dressing, Chronic ulcers, Non-healing ulcers, Diabetic ulcers, Venous ulcers
Background: Chronic non-healing ulcers; particularly diabetic and venous ulcers impose a major healthcare burden and affect quality of living. Efficacy of conventional strategies used for treatment of chronic non-healing ulcers is limited due to factors like microbial infection, necrotic tissues, tissue hypoxia, and other prevailing co-morbidities. The aim of the study was to compare efficiency of topical phenytoin-based dressings to conventional saline-based dressings for treatment of chronic non-healing wound ulcers.
Methods: A prospective observational study was conducted on 60 patients who were divided in two groups. First group received conventional saline dressing-based treatment and second received topical phenytoin dressing based treatment for chronic non-healing ulcers. Efficiency of the treatment strategy was determined by statistically comparing parameters like duration of hospital stay, nature of discharge, appearance of healthy granulation tissue, and pus culture evaluation upon admission and post one and two weeks of treatment.
Results: Diabetes and trauma were observed to be two major causes of chronic non-healing ulcers. No cases of venous impairment and osteomyelitis were observed in participating patients. Topical phenytoin dressing based treatment significantly reduced the duration of hospital stay and number of patients with serous discharge and aided in rapid formation of healthy granulation tissue in comparison to conventional saline based dressings. Topical phenytoin dressings also prevented microbial infection and colonization on chronic non-healing ulcers.
Conclusions: Topical phenytoin-based dressing was concluded to efficiently and rapidly heal chronic ulcers while preventing microbial infection in comparison to conventional saline-based dressings.
