Unna boot central gauze technique for chronic venous leg ulcers. Gao, Anne L; Cole, Justin G; Stoecker, William V

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 v...
