[Thoracoscopic surgery using a new bronchial blocker]

Area of Science:

• Thoracic Surgery
• Anesthesiology
• Pulmonology

Context:

• Performing thoracoscopic operations requires precise lung isolation for one-lung ventilation.
• Traditional double-lumen endotracheal tubes (DLTs) are standard but can be challenging to place in certain patients.
• Difficult intubation or anatomical variations can preclude DLT use, necessitating alternative strategies.

Purpose:

• To evaluate the safety and efficacy of a novel bronchial blocker delivered through a single-lumen endotracheal tube (SLT).
• To assess its utility in patients where DLT placement is predicted to be difficult or has previously failed.
• To facilitate one-lung ventilation for thoracoscopic procedures in challenging cases.

Summary:

• A new bronchial blocker was successfully used with an SLT to achieve one-lung ventilation in four patients undergoing thoracoscopic surgery.
• Bronchoscopic guidance ensured safe, rapid, and accurate placement of the bronchial blocker.
• The procedure was completed without any complications, demonstrating the device's feasibility.

Impact:

• This novel bronchial blocker provides a viable alternative for one-lung ventilation when DLTs are not feasible.
• It expands anesthetic options for thoracoscopic surgery in patients with difficult airways or anatomy.
• Further investigation in larger patient cohorts is warranted to confirm these preliminary findings.
