Lung cancer is the leading cause of cancer death worldwide. It may present as airway obstruction in a patient with endobronchial masses. Endobronchial brachytherapy (EBBT) has been shown to provide palliative therapy. It is the insertion of a radioactive material near the mass to reduce tumor size, thereby improving airway obstruction. This is the first case of EBBT done in our institution during the COVID-19 pandemic. A 53-year-old male, 60 kg, ASA Physical Status 2 for hypertension, smoker, malignancy, and previous pulmonary tuberculosis patient, presented with a cough and dyspnea. An endobronchial mass almost obstructing the right mainstem bronchus was seen on a computed tomography (CT) scan. He was diagnosed with squamous cell carcinoma of the lung and underwent radiotherapy and erlotinib chemotherapy. On repeat CT scan, there was no noted decrease in the size of the mass. EBBT was suggested, and a multi-disciplinary team was formed for the planned procedure. Pulmonology, radiation oncology, and anesthesiology teams were identified, and thorough planning was done prior to the actual procedure. Three fractions of EBBT were done under sedation using midazolam, fentanyl, and dexmedetomidine infusion. Lidocaine spray and transtracheal block were also performed as adjuncts prior to sedation. The procedure went as planned, and points for improvement were discussed for subsequent fractions. Due to persistent cough and discomfort from the catheter, additional ipratropium nebulization for minimization of secretions, and oral dextromethorphan for cough suppression were incorporated. After each fraction, the patient was monitored post-procedure for any side effects both from the radiotherapy and anesthetic technique. Qualitative reduction in mass size was noted in subsequent fractions. The patient was able to complete 3 fractions and was advised to follow-up after a month. EBBT is an emerging palliative and treatment modality for lung cancer, especially for intraluminal masses. Anesthetic considerations will depend on each case’s characteristics such as airway anatomy, patient comfort and capacity, and procedural requirements. Conscious sedation with topical anesthesia is an adequate and appropriate anesthetic option, especially in cases where severe airway obstruction may compromise ventilation if airway reflexes are blunted. A multidisciplinary approach with different services and stakeholders is important for the proper planning, execution, and management of such patients.
