Double-lumen endotracheal tubes and bronchial blockers exhibit similar lung collapse physiology during lung isolation

Double-Lumen Endotracheal Tubes

A comparison of a left-sided Broncho-Cath with the torque control blocker univent and the wire-guided blocker.

UNLABELLED Lung isolation can be accomplished in two ways: the first, a double-lumen endotracheal tube (DLT) and the second, a bronchial blocker (Univent or Arndt blocker). Previous studies have found that the DLT and the Univent are comparable when providing lung isolation. A new bronchial blocker, the wire-guided endobronchial blocker (Arndt blocker), has been introduced. However, there is no...

[Use of bronchial blocker in emergent thoracotomy in presence of upper airway hemorrhage, and cervical spine fracture: a difficult decision].

Female, 85 y.o., weighting 60kg, multiple trauma patient. After an initial laparotomy, an emergent thoracotomy was performed using a bronchial blocker for lung isolation (initial active suction was applied). During surgery, bronchial cuff was deflated, causing a self-limited tracheal blood flooding. A second lung isolation was attempted but it was not as effective as initially. Probably, a lung...

Double-lumen endotracheal tube for one-lung ventilation through a fresh tracheostomy stoma: a case report.

For one-lung ventilation in many surgical cases, double-lumen endotracheal tubes are the first-line choice for airway management. For most cases, double-lumen endotracheal tubes are faster, easier to place, cheaper, and less prone to malposition than today's bronchial blocker devices. This report describes an elective tracheostomy and the use of a double-lumen endotracheal tube directly through...

Delayed lumen obstruction in endotracheal tubes.

Delayed onset of obstruction in the Oxford endotracheal tube during anaesthesia is described in five patients. The effects of intra-cuff voluem and pressure on the wall of the tube were investigated and discussed with special refernce to the ffects of body heat and repeated use on the consistency of the tube. It is concluded that inward collapse of the tube wall is caused by a combination of fa...
