About

either uses a bougie or nasogastric tube to assist the nasotracheal tube passing the nasal cavity, nasopharynx, oropharynx and advanced into the trachea

Full 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.

90 participants in 3 patient groups

bougie group

Experimental group

Description:

The bougie group: The end of the endotracheal tube was guided to the glottis using the endotracheal tube in the bougie mode under the direct view of the electronic imaging laryngoscope. The Magill Forceps is used to assist the tip of the endotracheal tube in guiding the glottis.

Treatment:

Device: bougie

Nasogastric(NG) tube group

Experimental group

Description:

NG tube group: The end of the endotracheal tube is guided to the glottis by using the endotracheal tube in the nasogastric tube under the direct view of the electronic imaging laryngoscope. The Magill Forceps is used to assist the tip of the endotracheal tube in guiding the glottis.

Treatment:

Device: Nasogastric(NG) tube

control group

No Intervention group

Description:

Control group: The general anesthesia method of placing the endotracheal tube through the nasal cavity is used to guide the tip of the endotracheal tube to the glottis under the direct view of the electronic imaging laryngoscope.
