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


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.

Medical and Biotech [MESH] Definitions

A procedure involving placement of a tube into the trachea through the mouth or nose in order to provide a patient with oxygen and anesthesia.

The insertion of a tube into the stomach, intestines, or other portion of the gastrointestinal tract to allow for the passage of food products, etc.

Introduction of a tube into a hollow organ to restore or maintain patency if obstructed. It is differentiated from CATHETERIZATION in that the insertion of a catheter is usually performed for the introducing or withdrawing of fluids from the body.

Nutritional support given via the alimentary canal or any route connected to the gastrointestinal system (i.e., the enteral route). This includes oral feeding, sip feeding, and tube feeding using nasogastric, gastrostomy, and jejunostomy tubes.

Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.
