褥瘡に対するラップ療法の試み : ポリ塩化ビニリデン製食品包装用フィルムを用いた褥瘡治療

A food wrap film was used as a part of therapeutic materials for 34 decubitus ulcers in 29 patients, 15 males and 14 females, who were hospitalized in our departments from June 2000 to May 2001. Basic diseases of the patients consisted of 10 cerebrovascular diseases, 4 cephalic injury sequelae, 3 spinal diseases, 3 femur fractures, and 9 other diseases. Treatment of the decubitus ulcers was done everyday mostly according to Toriyabe’s method. Firstly, the bedsore was rinsed with physiological saline without applying pressure. Then, the ulcer including surrounding skin was covered with plastic food wrap (polyvinylidene chloride food wrapping film). Edge of the film was fixed to the skin with non-woven fabric tape. The results were evaluated by measuring two-dimensional sizes of the ulcers every two to four weeks. Reduction rate of the ulcer was calculated following formula : ((1-present size (maximal diameter×perpendicular size)/original size (maximal diameter×perpendicular size)×100)) (%) in 19 lesions followed more than one month. An average reduction rate was 43.7% at 3 months and 87.9% at 7 months after starting the food wrap film therapy. Moreover, 3 lesions got complete healing during the observation period. We strongly recommend the food wrap film therapy for the treatment of decubitus ulcers because it is simple to handle and extremely inexpensive, as well as effective.
