ABSTRACT
BACKGROUND:
Venous leg ulcers generally take manyweeks to heal. Novel therapies that shorten healingtime and require less complex care are needed.PURPOSE:
The purpose of this report is to presenta pilot study for a new method that can result ina faster healing time for venous leg ulcers usinginexpensive materials.METHODS:
A central-gauzeprotocol was developed as described here. A three-ply gauze sponge was placed in the center of theulcer, allowing a peripheral 3-5 mm rim of ulcer toremain exposed. Saline solution was applied to thegauze sponge. A 3-layer Unna boot was applied overthe ulcer with short-stretch compression. This noveltechnique exposed only a peripheral rim of the ulcerto the zinc oxide paste, allowing the central portionof the ulcer to drain through the saline-soaked gauze.The ulcer was photographed at each clinic visit andthe wound area was estimated by finding the bestfitellipse for the ulcer area and computing the areaof the ellipse by a standard formula.RESULTS:
Threepatients with small venous leg ulcers treated with thezinc rim technique showed an average healing rate of46.1% per week (range 27.8% - 50.7%). All ulcers werenearly healed by three weeks. After the ulcer size wasreduced sufficiently, patients were discharged withinstructions to apply pieces of Unna dressing to theulcer, under a conventional self-adhesive bandage,maintaining compression, without any saline-gauzein the center.CONCLUSIONS:
The three patients in thispilot study showed rapid healing for venous leg ulcerswith the central gauze modification of Unna boottherapy.
