About

The purpose of this study is to determine whether the double-lumen endotracheal tube or the standard single-lumen tracheal tube, with an Arndt® blocker, is superior in providing one lung ventilation during thoracic surgery.

Full description

The purpose of the study is to compare a double lumen tube versus the standard single-lumen tracheal tube, with an Arndt® blocker, in the morbidly obese patient who requires one-lung ventilation during surgery. The objects is to determine which device is best for intubation and is most effective in terms of optimal positioning of the device, of lung collapse, and quality of lung isolation.

Double Lumen Endotracheal Tube

Active Comparator group

Description:

We used a device called a double lumen tube ( DLT Broncho-Cath®). It is a bifurcated endotracheal tube designed to independently collapse the operated lung.

Treatment:

Device: Double Lumen Endotracheal Tube

Arndt Bronchial Blocker

Active Comparator group

Description:

We used a device called a bronchial blocker (9 Fr Arndt® blocker) along with a standard single-lumen tracheal tube (8.0-9.0 mm ID). The Arndt bronchial blocker is a single device, with a distal balloon that is passed thru the single lumen endotracheal once the patient is intubated. The Arndt bronchial blocker is designed to collapse the operated lung.

Treatment:

Device: Arndt Bronchial Blocker
