The EZ- Blocker®- A Safer Alternative in Complex Airway Scenarios: A Case Series

One-lung ventilation (OLV) is crucial in thoracic surgery as it ensures optimal visibility and effective isolation of the lung. Various devices, such as double-lumen tubes and bronchial blockers, help achieve effective OLV. While double-lumen tubes (DLTs) are considered the gold standard for lung isolation certain clinical scenarios may make their use challenging or contraindicated. In these cases, the EZ-Blocker® (Teleflex Medical, Morrisville, NC, USA) presents distinct advantages. This paper discusses a series of six cases where DLTs were not feasible, highlighting our experience with the EZ-Blocker® as a viable alternative.

We analyzed patients aged 18 years and older who underwent various thoracic surgeries in the department of Anaesthesiology at Christian Medical College, Vellore, from January 2024 to September 2024. This study specifically focused on cases involving the intraoperative use of the EZ-Blocker® for one-lung ventilation.

The EZ-Blocker® was used in challenging situations such as difficult airway management, and lung isolation in intubated patients, and in those with tracheostomies. The placement of nearly all EZ bronchial blockers was accomplished without complications, resulting in a success rate of 99%. Adequate lung collapse was achieved in all patients, with no serious airway injuries or immediate complications reported.

The EZ-Blocker® is an effective and safe airway device designed for one-lung ventilation, particularly in scenarios where DLTs are unsuitable. Its advantages include easy placement, adaptability to abnormal airway anatomy, reduced airway trauma, and enhanced visualization during bronchoscopy. These features make it a superior alternative to traditional double-lumen tubes for managing complex airway scenarios.
