Nasotracheal intubation with general anesthesia is performed for dental treatment and oral surgery. However, nasotracheal intubation causes nasal bleeding and injury to the mucous membrane of the nasopharynx. This report describes the introduction of Nasogastric tubes with the guide intubation (NTGI) method and discusses its usefulness, and further reports a comparison of the clinical usefulness of the NTGI method (our novel method) and the bougie inferior nasal meatus (BINI) method. The NTGI was performed clinically and the results of 30cases were confirmed by fiberscopy, showing no cases of injury. The proportion of cases with bleeding from the inferior nasal meatus was similar in the NTGI and bougie inferior nasal meatus as nasotracheal intubation (BINI) methods. The NTGI method prevented injury to the pharyngeal mucous membrane at the time of nasotracheal intubation. Therefore, the results indicated that the NTGI method is safe for nasotracheal intubation. In the present study, the intubation tube was changed to prevent pharyngeal injury. The tube tip was made of a soft material (soft PVC ; polyvinyl chloride) and with an obtuse angle, and the tube shape was changed. Although the intubation procedures were safe because the intubation tube material was soft, there is the possibility of obstruction of the nasal cavity during general anesthesia. Further studies are required to develop tubes for safer tracheal intubation during general anesthesia and when regaining consciousness as well as during intubation.
