Cement is a widely used mixture in construction. A corrosive alkali, calcium hydroxide, is liberated as water is added to the lime present in the cement mixture. Skin contact for prolonged periods produces deep chemical burns with thick eschar formation. Five cases of chemical burns to the lower extremities following contact with the cement mixture are presented. When full-thickness burns were present, long periods of hospitalization were necessary for eschar separation prior to skin grafting. Early excision of full-thickness caustic burns with immediate skin grafting diminished the length of hospitalization and returned the patient to work sooner.
水泥是建筑中广泛使用的一种混合物。当向水泥混合物中存在的石灰加水时，会释放出一种腐蚀性碱——氢氧化钙。长时间的皮肤接触会产生深度化学烧伤并形成厚厚的焦痂。本文介绍了5例接触水泥混合物后下肢化学烧伤的病例。当出现全层烧伤时，在进行皮肤移植之前，需要长时间住院以等待焦痂分离。早期切除全层苛性烧伤并立即进行皮肤移植可缩短住院时间，并使患者更快恢复工作。
