Abstract:

Summary：Establishment and maintenance of fluent respiratory tract is important in management of general anesthesia in surgery for oral and maxillofacial injuries. Patients with oral and maxillofacial injuries are likely to have obstruction of respiratory tract，especially patients with coma，massive hemorrhage，foreign bodies in respiratory tract and wallowing tongue base. Studies showed that the mortality caused by respiratory problems is higher than that caused by injury itself in patients with oral and maxillofacial injuries. Along with the innovation of anesthesia，in-depth understanding of difficult respiratory tract and development of new anesthetic or instrument，more and more methods can be attained for management of the respiratory tract in surgery for oral and maxillofacial injuries. The pivot of maintenance of fluent respiratory tract is taking effective steps to avoid lack of oxygen in pre-operation period. It is also important to use all kinds of intubation methods and technologies skillfully.
