[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. ⋯ Bronchial blocker active suction may contribute to obtain or accelerate lung collapse, particularly in patients that do not tolerate ventilator disconnection technique or lung surgical compression. The use of bronchial blockers technology was a valuable alternative to double lumen tubes in this case of emergent thoracotomy in the context of a patient having thoracic, abdominal trauma, severe laceration of tongue and apophysis odontoid fracture associated to massive hemorrhage, despite several pitfalls that could compromise its use. The authors intend to discuss the advantages and disadvantages of bronchial blockers comparing to double-lumen tubes for lung isolation, and the risks of our approach, in this complex multitrauma case.

The EZ-blocker for one-lung ventilation in patients undergoing thoracic surgery: clinical applications and experience in 100 cases in a routine clinical setting.
In certain clinical situations the insertion of a double-lumen tube (DLT) for one-lung ventilation (OLV) is not feasible or unfavorable. In these cases, the EZ-Blocker (EZB) may serve as an alternative. The aim of our analysis was to report on the clinical applications and our experience with the EZB for one-lung ventilation in 100 patients undergoing thoracic surgery. ⋯ The EZB is an efficient, easy-to-use and safe airway device and enables OLV in several clinical situations, when conventional DLTs are not feasible or less favorable. Three major applications were depicted from the data: expected difficult airway, surgical procedures with necessity of intraoperative recurrent laryngeal nerve monitoring and already intubated or tracheostomized patients.

An initial experience with an Extraluminal EZ-Blocker® : A new alternative for 1-lung ventilation in pediatric patients.
The need for 1-lung ventilation in school age, pediatric patients is uncommon and as a result there are relatively few devices available to facilitate lung isolation in this population. Furthermore, little is known about the efficacy and techniques of placement of the currently available devices. One of the newest devices available that may be appropriate in this age group is the EZ-Blocker. ⋯ The EZ-Blocker was successful in providing lung isolation for a majority of our school age patients. Size constraints in children <6 years of age, excessive secretions, and distortions of tracheal anatomy seemed to be the greatest hindrances to successful placement and positioning of the device. Once correctly positioned, however, the EZ-Blocker may be more stable than the Arndt endobronchial blocker.

Randomized Controlled Trial Comparative StudyComparison of Univent tube and EZ blocker in one lung ventilation; airway pressures and gas exchange.
Univent tube (UT) and EZ-blocker were used for one-lung ventilation (OLV). UT is a single lumen tube with a small separate lumen containing a bronchial blocker. EZ-blocker differs with its unique y-shaped double-cuffed distal end. ⋯ ABG findings and haemodynamic variables were similar. EZ and Univent tube affected the airway pressures, oxygenation, ventilation and haemodynamic variables similarly during OLV in patients with normal respiratory function. These devices can be alternatives to each other based on clinical conditions.

Randomized Controlled Trial Comparative StudyBronchial Blocker Versus Left Double-Lumen Endotracheal Tube for One-Lung Ventilation in Right Video-Assisted Thoracoscopic Surgery.
The aim of this study was to compare the quality of lung deflation of a left-sided double-lumen endotracheal tube (DLT) with a bronchial blocker (BB) for one-lung ventilation in video-assisted thoracic surgery (VATS). ⋯ The results of this study showed that BB is an effective alternative for left one-lung ventilation in right VATS, but requires a longer time to achieve complete lung collapse. Moreover, the use of BB caused less hemodynamic perturbation and can reduce postoperative hoarseness and sore throat.
