Postoperative pulmonary complications and response to recruitment maneuvers during hypoxemia in one lung ventilation.
Observational study in BMC anesthesiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPulmonary atelectasis during one-lung ventilation (OLV) can cause intraoperative hypoxemia and is a risk factor for postoperative pulmonary complications (PPCs).
objectivesWe hypothesized that patients whose hypoxemia improves with recruitment maneuvers (RMs) have atelectasis-related hypoxemia and a higher risk of PPCs compared to those with hypoxemia unresponsive to RMs.
designRetrospective and observational study. SETTINGS: Single-entry study conducted in a University Hospital. PATIENTS: Adults patients (n = 195) with elective pulmonary lobectomy.
main outcome measuresBetween April 2022 and March 2023, all thoracic surgergy patients were classified into three groups: no intraoperative hypoxemia, hypoxemia responsive to RMs, and hypoxemia non-responsive to RMs. Postoperative outcomes were compared among groups, including incidence of respiratory distress, pneumonia, and RALE scores.
resultsPatients responsive to RMs had significantly higher rates of early (Day 0–4) respiratory distress (21.4% vs. 0% vs. 8.7%; p = 0.04) and late (Day 5–7) pneumonia (28.6% vs. 9% vs. 7%; p < 0.001). Non-responders showed higher intraoperative airway pressures and higher RALE scores on Day 1, which normalized by Day 3. No significant differences in mechanical ventilation duration or ICU stay were observed.
conclusionPatients with hypoxemia responsive to RMs during OLV are at increased risk of PPCs, particularly respiratory distress and pneumonia, suggesting that intraoperative atelectasis is a major contributor. Identifying the hypoxemia profile could guide tailored perioperative strategies to minimize PPCs in these high-risk patients.
