About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

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.

Disqualifiers

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

Emergency surgeries.

Trial design

Design model

Parallel

Treatments tested in this trial

  • One-Lung ventilation with Double-Lumen Tube

    Device

    To achieve the required one-lung ventilation during lung resection, patients will be managed with a double-lumen tube.

  • One-Lung Ventilation with Bronchial Blocker

    Device

    To achieve the required one-lung ventilation during lung resection, patients will be managed with a bronchial blocker.

Treatment groups

46 Participants
are divided into 2 treatment groups
Group A: Bronchial BlockerExperimental treatment 1 intervention
Group B: Double-Lumen TubeExperimental treatment 1 intervention

Trial outcomes

Primary outcomes

1

Hypoxia

While its definition is somewhat arbitrary, the investigators consider hypoxia as SpO₂ \< 90%, while maintaining FiO₂ = 1.0, in accordance to our hospital guidelines.

Time frame
Intraoperative (both from anesthetic induction to one-lung ventilation, and during one-lung ventilation)

Secondary outcomes

1

Lung collapse

Assessed by the anaesthesiologist as: Excellent: complete lung collapse, perfect surgical visualization; Good: complete collapse, residual air; Poor: non-achieved collapse or partial collapse that interfered with surgical visualization.

Time frame
Intraoperative
2

Surgical visualization

Assessed by the thoracic surgeon as excellent, good or poor.

Time frame
Intraoperative
3

Insertion time of the ventilation device

Time in minutes from the beginning of ventilation device insertion until correct placement is confirmed.

Time frame
Intraoperative
4

Repositioning of the ventilation device

Number of repositioning attempts of the ventilation device.

Time frame
Intraoperative

Other outcomes

1

Sex

Male or female.

Time frame
Preoperative
2

Age

Age at the time of the procedure (years).

Time frame
Preoperative
3

Obesity

Categorized as: Grade I (BMI: 30-34.9); Grade II (BMI: 35-35.9); Grade III (BMI≥ 40).

Time frame
Preoperative
4

Charlson Comorbidity Index

The Charlson Comorbidity Index (CCI) is a validated scoring system used to predict 10-year mortality by assigning weighted scores to 19 comorbid conditions, based on their severity. The total score reflects both the number and seriousness of comorbid diseases, with higher scores indicating a greater comorbidity burden. Values range from 0 to 33.

Time frame
