Bronchial blocker versus double‑lumen tube for one‑lung ventilation in people with obesity
One-lung Ventilation With Double-Lumen Tubes and Bronchial Blockers in Obese Patients Undergoing Lung Resection
NA · Hospital Son Espases · NCT07031986
This study tests whether bronchial blockers or double‑lumen tubes lead to less low oxygen (hypoxia) during one‑lung ventilation for people with obesity having lung resection surgery.

What this trial studies
The trial compares two airway devices—bronchial blockers and double‑lumen tubes—in obese adults undergoing planned lung resection (lobectomy, segmentectomy, or wedge) by VATS or thoracotomy that require one‑lung ventilation. Researchers will record intraoperative oxygen levels and other safety and efficacy measures while standard anesthesia care is provided. Patients will be assigned to receive one of the two devices during their surgery and no extra tasks are required. The primary focus is whether the choice of device changes the frequency or severity of intraoperative hypoxia.
Who should consider this trial
Good fit: Adults with BMI ≥ 30 kg/m2 who have diagnostic or clinical suspicion of lung cancer and are scheduled for elective lung resection requiring one‑lung ventilation are the intended participants.
Not a fit: Patients with airway anatomic alterations that contraindicate double‑lumen tubes, emergency surgery cases, or those not undergoing lung resection would not be eligible and are unlikely to benefit from the findings.
Why it matters
Potential benefit: If successful, the results could identify which device reduces intraoperative hypoxia and complications, helping anesthesiologists choose the safer option for obese patients.
How similar studies have performed: Previous comparisons of bronchial blockers and double‑lumen tubes have produced mixed results and obese‑specific data are limited, so this trial addresses a relatively under‑studied subgroup.
