Comparison of Different Tools Inserted Nasal Endotracheal Tube

A Comparson Among the Use of Direct Laryngoscope.AirwayScope and GlideScope in General Anesthetized Patients Who Require Nasal Endotracheal Tube Intubation

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.
