Use of the flexible fiberoptic laryngoscope to change endotracheal tube / 대한마취과학회지

The fiberscope is no longer an experimental instrument, and it is a state-of-the-art technique for airway management in the operating room, recovery room, and intensive care unit. Changing the oral tube to a nasal one is often necessary if the trachea is to be intubated for a long period. A nasal tube is better tolerated by the patient, is easier to secure when the patient is moved, and is easier to attach to the respiratory care equipment. We describe three cases report changing the oral tube to a nasal one in neurosurgical pa- tient post operatively under flexible fiberoptic laryngoscope, while the interruption of venti- lation is minimized.

Clinical experience of blind nasotracheal intubation for conscious patient / 대한마취과학회지

Blind nasotrscheal intubation with preformed tube has been attempted in 20 conscious young male scheduled for surgical reduction of mandibular fracture. The patient was premedicated in the usual fashion with glycopyrrolate -midszolam- fentanyl. Airway anesthesia was performed with topical lidocaine ; Nasopharyngeal and translaryngeal. Of the 20 patients in whom intubation was performed, 12 (60%) required one to three attempts, 6 (30%) required four to six, and only two failures occurred. Contrary to our expectation, this procedure met with almost positive acceptance by the patients in the series, and the surgical staff had no adverse criticism. In addition to the effectiveness and ease of learning, this technique is simple and free from major morbidity.
