Bronchial Blockers vs Double-Lumen Tubes in Obese Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

One-Lung ventilation with Double-Lumen Tube: 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: To achieve the required one-lung ventilation during lung resection, patients will be managed with a bronchial blocker.

Study summary

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

Primary outcome measure(s)

• Hypoxia — Intraoperative (both from anesthetic induction to one-lung ventilation, and during one-lung ventilation)
  While its definition is somewhat arbitrary, the investigators consider hypoxia as SpO₂ \< 90%, while maintaining FiO₂ = 1.0, in accordance to our hospital guidelines.
