To investigate the effective principles of early management in extensively burned patients,162 patients (from 1990 to 1999) with extensive burn were treated according to the following principles: ① prompt and rapid fluid resuscitation during shock stage for delayed resuscitation patients; ② early tracheostomy,air way humidification and lavage for moderate and severe inhalation injury;③ escharectomy and grafting performed during early stage, presenting the experiences of escharectomy during shock stage in grassroot hospitals ; ④ undergoing enteral nutritional support in early stage; ⑤ emphasizing the importance of functional excise in early stage to stress that rehabilitation therapy should be implemented throughout that whole course of treatment. The results showed that the successful rate of treatment was raised and the incidence of complications and disability decreased after implementing the aforementioned treatment principles in extensively burned patients. It is suggested that the application of “Five early Principle” on extensively burned patients is effective and feasible
