Effect of Salbutamol on Oxygen Levels in COPD Patients During Lung Surgery

Assessment of Salbutamol Effect on Arterial Oxygenation in COPD Patients During One-lung Ventilation

NA · Yonsei University · NCT05914285

This study is testing if inhaling salbutamol can help improve oxygen levels in COPD patients during lung surgery when only one lung is being used for breathing.

What this trial studies

This study investigates the impact of inhaled salbutamol on arterial oxygenation in patients with chronic obstructive pulmonary disease (COPD) undergoing one-lung ventilation during thoracic surgery. One-lung ventilation can lead to significant hypoxemia due to ventilation-perfusion mismatch, particularly in COPD patients. The study hypothesizes that salbutamol, a beta2-agonist, will improve oxygenation by reducing pulmonary vascular resistance in the ventilated lung. Participants will receive either inhaled salbutamol or normal saline to assess its effectiveness.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40 to 80 with moderate to severe COPD scheduled for pulmonary lobectomy.

Not a fit: Patients with severe heart conditions, recent myocardial infarction, or significant renal impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance oxygenation and reduce complications during lung surgeries for COPD patients.

How similar studies have performed: While the specific use of salbutamol in this context may be novel, similar studies have shown that beta2-agonists can improve pulmonary function in COPD patients.
