Brief summary

Nasotracheal intubation (NTI) is usually required in patients undergoing maxillofacial surgery. Though video-scopes have been demonstrated to well perform in oral endotracheal intubation, limited information presents in NTI. The aim of the study is to compare the efficacy of video-scopes in NTI and compared with the traditional direct laryngoscope.

Design outcomes

Primary

Measure	Time frame	Description
number of the patients with successful nasotracheal intubation and scoring difficult intubation scale	half an hour	Nasotracheal intubation assisted by a video-stylet may be performed in patients following induction of anesthesia (fentanyl 2 micro-gram/kg, thiamylal 5 mg/kg, cis-atracurium 0.2 mg/kg and propofol 1 mg/kg)

Secondary

Measure	Time frame	Description
time to intubate	10 minutes	time of Intubating the nasotracheal tube (NT) from selected nostril to trachea is continuously calculated but separately into two parts. part one: from termination of mask ventilation and mask removed from face, to the NT tip on the nasopharynx. part two: advancing NT from nasopharynx, through vocal cord into trachea, to present of 3 end tidal carbon dioxide waveforms.

Other

Measure	Time frame	Description
postoperative nasal bleeding, sore throat and hoarseness	2 days	Events of intubating related nasal bleeding are recorded on selected nostril and oral cavity at 3 minutes post-intubation and post-operatively. Incidences of sore throat and hoarseness are evaluated before patients out of recovery room and the following morning
