Introduction: Diabetic foot has become the common indication for hospital admissions
among diabetics. The diabetic foot commonly begins as an ulcer. So rapid and extensive
is the underlying damage that approximately 20% of these patients end up with
amputation. The present study has been performed to compare the efficacy of collagen
dressing with that of conventional dressing materials like silver sulfadiazine,
nadifloxacin, povidone iodine.
Materials and Methods: Fifty patients (40 males and 10 females) were procured to be
included to experimental group who were treated using collagen dressing and they form
the study group. Control treatment was performed on 25 patients (21 males and 4
females) at the same period. All the quantitative values were noted as mean± standard
Results: 1. The final ulcer sizes (by the 3-week measurement) ranged between 0.2 and
4.2 cm2 (mean, 1.11 ± 1.19 cm2) in the experimental group, and ranged between 0.1 and
12.8 cm2 (mean, 2.52 ± 2.61 cm2) in the control group. It was found that all of 25
patients of the experimental group were reported with shrinkage of wound area and
depth over 30% at the third week regardless of wound location, duration, and grade. In
contrast, the improvement of only 5 ulcers in area over 30% at the third week was
observed, and 6 in depth.
Conclusion: Collagen dressing also might also provide supplementary advantages of
patients’ comfort and compliance as well as maintenance of ideal healing environment.
In order to confirm the usefulness and wound healing potential of collagen dressing in
the management of diabetic foot ulcers, future research with longer follow-up periods
should be conducted.
