Background:
The Airtraq optical laryngoscope allows visualization of the glottis through a non-line-of sight view. The aim of the present study was to evaluate the suitability of this device for the tracheal intubation of surgical patients.
Methods:
The Airtraq was used for the endotracheal intubation in 300 surgical patients.
Results:
The Airtraq optical laryngoscope allowed visualization of the glottis and successful intubation in 298 out of 300 patients. Endotracheal intubations were easily performed both with normal and difficult airways.
Conclusions:
The Airtraq optical laryngoscope consistently permitted a better intubation environment. With its potential advantages, the Airtraq optical laryngoscope could be an effective aid to airway management in surgical patients.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
