Abstract:
Twenty-nine patients undergoing left thoracotomy consecutively were intubated with right-sided double-lumen endotracheal tubes in the conventional "blind" fashion. The first 20 received Leyland red-rubber double-lumen tubes, and the subsequent nine received Mallinckrodt polyvinylchloride double-lumen tubes. The patency of the right upper lobe bronchial orifice was then assessed by flexible fiberoptic bronchoscopy. Right upper lobe obstruction occurred in 89% of the polyvinylchloride tube intubations and in 10% of the red-rubber tube intubations.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

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...
