A Qualitative Study to Analyze the Effect of Plaster of Paris Slab on Wound Healing of Diabetic Foot Ulcers among Diabetics Attending Tertiary Hospital
Background: As diabetic foot is a very common in Indian population and the burden it exerts upon the health system is enormous
this study was undertaken. The study was carried out to evaluate the promotion in the rate of wound healing in patients with
diabetic foot ulcer undergoing saline dressing with posterior below knee plaster of paris slab (experimental arm) as against the
rate of wound healing with only saline.
Materials and Methods: The study was carried out in the Department of General Surgery in Saveetha Medical College and
Hospital for a period of 6 months with fifty patients included in the study. The patients were randomly divided into two groups,
one arm receiving saline dressing and plaster of Paris slab and other arm receiving only saline dressing. Patients were followed
every 2 weeks for a period of 6 weeks. The results were considered significant if P < 0.05.
Results: At the end of the study, patients receiving saline dressing with plaster of Paris slab demonstrated an accelerated wound
healing, with nearly 40% of patient in experimental group demonstrating wound size <30 cm2 as against control group with only
12% demonstrating wound size of <30 cm2. Each serial follow up demonstrated significant p value, favoring plaster of Paris slab
dressing over saline dressing alone.
Conclusion: Applying plaster of Paris slab to diabetic foot ulcers, apart from the fact of accelerated wound healing also offers
to be cost effective with reduced economical burden. Hence it has become a norm in my surgical unit to adopt this approach.
