Summary

During thoracic surgery, one-lung ventilation (OLV) is associated with hypoxemia, lung injury, and perioperative respiratory complications. The level of positive-end expiratory pressure (PEEP) to apply during OLV remains controversial. The open-lung approach consists in setting a level of PEEP corresponding to the best lung compliance, using an esophageal catheter to measure the transpulmonary pressure. This approach has been effective in laparoscopic surgeries or acute respiratory distress syndrome, but has never been evaluated in thoracic surgery.

Interventions

PROCEDURE

"Open-lung" protective ventilation strategy

In the "open-lung" group, the positive end-tidal pressure (PEEP) is titrated to match the best lung compliance. During a "PEEP decrement trial", PEEP is decreased from 20 cmH2O to 4 cmH2O by steps of 2 cmH2O/minute, and the driving the transpulmonary pressure (PTP) is calculated at each level of PEEP. In the "open-lung" group, the targeted PEEP corresponds to the lowest driving PTP during the "PEEP decrement trial", meaning the best lung compliance. Thereafter, the PEEP is set at this level and maintained until extubation.

PROCEDURE

"Standard" protective ventilation strategy

In the "standard" group, the positive end-tidal pressure (PEEP) is arbitrarily set at 5 cmH2O, since this is the currently recommended level of PEEP, commonly used in control groups of previous clinical trials.
