纤维支气管镜引导气管插管在口腔颌面部手术中的应用

Objective To describe the application of fiberoptic bronchoscope（FOB） facilitated intubation in patients undergoing oral and maxillofacial surgery. Methods 122 patients with suspected difficult airway scheduled for oral and maxillofacial surgery were included in the study. All the patients were intubated under FOB facilitation with endotracheal tube after topical anesthesia or general anesthesia. The lubricated scope was inserted down the airway and the epiglottis and vocal cords were visualized by rotation and angulation of the scope. When the glottis was opening, the scope was gently introduced into trachea until about 5 cm over carina. Then the ensleeved endotracheal tube was advanced into trachea under direct vision and the scope was drawn back and out. After confirming the tip position of endotracheal tube, it was properly secured with sticking plaster. Results 122 patients were successfully intubated with facilitation of the FOB. Conclusion FOB guidance for endotracheal intubation markedly decreased the incidence of difficult intubation in patients undergoing oral and maxillofacial surgery. The application of this technique should be promoted as a standard procedure.
