Bronchial Blockers vs Double-Lumen Tubes in Obese Patients

One-lung Ventilation With Double-Lumen Tubes and Bronchial Blockers in Obese Patients Undergoing Lung Resection

The goal of this clinical trial is to evaluate the efficacy of bronchial blockers and double-lumen tubes in achieving one-lung ventilation in obese patients undergoing lung resections. The primary question it aims to answer is:

• Is intraoperative hypoxia significantly different depending on the device used?

Researchers will compare the use of bronchial blockers and double-lumen tubes to assess differences in efficacy and safety.

Participants will not be required to perform any tasks.

Inclusion Criteria:

• BMI ≥ 30 kg/m2
• Diagnostic or clinical suspicion of lung cancer
• Lung resection surgery (lobectomy, segmentectomy or wedge resection) by VATS or thoracotomy, requiring one-lung ventilation.
• Use of bronchial blocker or double-lumen tube for one-lung ventilation.

Exclusion Criteria:

• Patients with evident anatomic alterations, in which double-lumen tubes may be contraindicated.
• Emergency surgeries.
