Purpose Of Review: This review is a clinical comparison between double-lumen endotracheal tubes and bronchial blockers to determine which device is considered the best for lung isolation.
Recent Findings: Double-lumen endotracheal tubes and bronchial blockers have been found to be clinically equivalent in terms of performance in providing lung collapse for patients with normal airways. In the last five years, however, numerous reports have indicated a preference for the use of bronchial blockers in patients with airway abnormalities. For nonthoracic anesthesiologists who have limited experience in thoracic anesthesia cases, none of the devices (double-lumen tubes or bronchial blockers) have been shown to provide any advantage while in use due to a high incidence of unrecognized malpositions. Overall, each device provides advantages depending upon the case, such as absolute lung separation with a double-lumen endotracheal tube or the use of a bronchial blocker in a difficult airway for a patient requiring lung isolation.
Summary: Double-lumen endotracheal tubes and bronchial blockers should be part of the armamentarium of every anesthesiologist involved in lung isolation techniques and every device should be tailored to specific case needs.

Background: Several methods for blindly positioning bronchial blockers (BBs) for one-lung ventilation (OLV) have been proposed. However, these methods do not reliably ensure accurate positioning and proper direction. Here, we developed a clinically applicable two-stage maneuver by modifying a previously reported one-stage maneuver for successful insertion of a BB at the appropriate depth and direction in patients requiring lung isolation where a flexible bronchoscope (FOB) is not applicable.

Innovations and challenges for lung separation or isolation have evolved during the last few years. In this chapter, we present the up-to-date, robust evidence available during the previous five years supporting the positions of the different devices, techniques, and tricks for their use in adult and pediatric patients undergoing various thoracic surgical interventions. Additionally, we presented an update on lung isolation in patients with airway difficulty and the suggested training level to master these techniques.

Background: Acquired bronchobiliary fistula (BBF) is a rare but life-threatening complication that can occur as a result of oncological processes, inflammatory reactions, parasite infections, thoracoabdominal trauma, or invasive procedures associated with iatrogenic injury. However, the potential etiology of BBF caused by instrumental issues when using ultrasonic scalpels resulting in diathermy burn and its post-burn effects has never been reported.
Case Presentation: Herein, we present a case of a 65-year-old woman who developed BBF one month after hepatectomy and presented with refractory irritating cough accompanied by yellow bitter sputum.

Article Synopsis
- The study investigates two methods of bronchial blocker (BB) placement for lung isolation during thoracic surgery: electromagnetic navigation bronchoscopy (ENB) and fiberoptic bronchoscopy (FOB).
- It found that ENB-guided technique resulted in better subjective lung collapse scores and required significantly less time for correct BB placement compared to the FOB method.
- Despite these advantages, other factors like the incidence of malposition and patient vitals showed no significant differences between the two techniques.
