Overview
Brief Summary
either uses a bougie or nasogastric tube to assist the nasotracheal tube passing the nasal cavity, nasopharynx, oropharynx and advanced into the trachea
Detailed Description
In oro-maxillo-facial surgery, it is a common practice for patients receiving general anesthesia with nasotracheal intubation to widen the surgical field and to ease undergoing surgery. However, a nasotracheal tube blindly passing through the nasal cavity may easily result in nasal cavity and oropharynx damages. In addition, the advancement of the tube from oropharynx into trachea may assist by either using magic forceps or cuff inflation technique. The aim of the study is to investigate either use a bougie or nasogastric tube to assist the nasotracheal tube passing the nasal cavity, nasopharynx, oropharynx, and advanced into the trachea. Patients were randomized into three groups by using either bougie or nasogastric tube to facilitate nasotracheal tube sliding through into trachea from assigned nostril and compared with the control group with a conventional technique. Hemodynamic changes in each time interval, each time taken of tube going through the nasal cavity, tube advanced from oropharynx into trachea were recorded. The incidence of using Magill Forceps to accurately place tube tip into trachea, intubation related side effects and complications were recorded at postoperative time stages.
