Abstract: Ammonia is commonly used in industry and agriculture. It is also one of the most frequently accidentally spilled chemicals. Exposure to ammonia can cause severe cutaneous burn or freezing injury, ocular injury, and inhalation injury, among them inhalation injury is the most lethal one. Although the diagnosis and treatment of ammonia burns have been improved, the long–term prognosis is not satisfactory. In this article, we reviewed the literature concerning ammonia burns, in order to summarize the clinical features and treatment of such injury.
