The intersection of bronchoscopy and extracorporeal membrane oxygenation

Area of Science:

• Pulmonology
• Cardiothoracic Surgery
• Anesthesiology

Background:

• Central airway obstruction (CAO) presents with diverse etiologies (malignant, benign, iatrogenic) and can lead to severe respiratory distress.
• Patients with CAO often require immediate intervention due to the risk of impending respiratory failure.
• Multidisciplinary airway management is essential for optimizing patient care.

Purpose of the Study:

• To review anesthetic considerations for patients with CAO.
• To highlight the role of extracorporeal membrane oxygenation (ECMO) in managing severe CAO.
• To present cases where ECMO was successfully utilized to support patients during airway interventions.

Main Methods:

• Review of literature on CAO management and ECMO application.
• Discussion of interventional pulmonology techniques, including rigid and flexible bronchoscopy.
• Analysis of ECMO as a supportive measure in critical airway compromise scenarios.

Main Results:

• ECMO provides vital ventilation and oxygenation support during high-risk procedures for CAO.
• Venoarterial ECMO can augment cardiac output in cases of central tumors with cardiac involvement.
• ECMO serves as a salvage therapy for life-threatening hemoptysis and facilitates stent removal.

Conclusions:

• Short-term ECMO cannulation is associated with limited morbidity, with heparin-free options available.
• ECMO is a valuable tool for managing severe CAO, ensuring procedural safety and patient stability.
• Anesthetic management and ECMO utilization are critical for successful outcomes in CAO patients.
