Abstract: The change and fixation of dressing are difficult in patients with burn in special sites of perineum, buttocks, and bilateral thighs. Therefore, we designed and made stretch pants by ourselves for dressing fixation after dressing change in patients with burns in abdomen, buttocks, and bilateral thighs. The stretch pants are made by cutting and splicing elastic fabric according to perimeters of abdomen and legs. The stretch pants are used after wound dressing change, which can fix the dressing stably, accelerate wound healing, and reduce the medical workers′ labor intensity of dressing change and economic burden of patients. And patients can walk out of bed early. It′s especially suitable for dressing fixation of infants and other patients who are unwilling to cooperate. Besides, it′s easy to make with low cost and suitable for clinical promotion.
