What does this research mean for the field?

The failure of electrical impedance tomography-guided individualised PEEP to reduce composite postoperative pulmonary complications in lung cancer surgery reflects the limitations of the specific protocol and composite endpoint tested, rather than definitive evidence against individualised PEEP. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the clinical interpretation, methodological limits, and endpoint selection of a randomized trial assessing electrical impedance tomography-guided individualized PEEP during thoracic surgery.

Overview

Randomized trial commentary examines individualized positive end-expiratory pressure in thoracic surgery, suggesting composite endpoints may obscure benefits for ventilation-sensitive complications.

Key Points

To evaluate the clinical interpretation, methodological limits, and endpoint selection of a randomized trial assessing electrical impedance tomography-guided individualized PEEP during thoracic surgery.
Analyzed findings from an assessor-blind randomized trial evaluating a two-point electrical impedance tomography-guided PEEP titration strategy during one-lung and two-lung ventilation in older patients undergoing lung cancer surgery.
Evaluated the trial design limitations, including single-center execution, exclusion of patients with chronic airway disease or BMI > 35 kg/m², and the nature of the composite pulmonary complication endpoint.
Individualized PEEP titration improved intra-operative oxygenation and lowered driving pressure but did not reduce the overall composite postoperative pulmonary complication rate.
Prolonged air leak represented the most frequent pulmonary complication, occurring in 13% of patients in each trial group, reflecting a surgical endpoint largely unmodifiable by brief ventilatory adjustments.
Isolated intra-operative PEEP optimization alone may be insufficient to impact broad thoracic complication composites without broader peri-operative open-lung care bundles or patient-phenotype selection.
