1 · What the graph read from it

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.

2 · The registry

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

purposeOne-lung ventilation (OLV) frequently induces hypoxemia. This study investigated whether intraoperative esketamine is non-inferior to dexmedetomidine in maintaining oxygenation during OLV and evaluated its impact on postoperative recovery.

methodsIn this prospective, double-blind, non-inferiority trial, 126 adults undergoing thoracoscopic surgery were randomized to saline (Control), dexmedetomidine, or esketamine. The primary outcome was PaO₂/FiO₂ (P/F) ratio at 60 min after OLV initiation. The key secondary outcome was Quality of Recovery-15 (QoR-15) at 24 h. Linear mixed effects models were used.

resultsA total of 120 patients were included in the modified intention-to-treat analysis. At T3, esketamine was noninferior to dexmedetomidine for P/F ratio (adjusted mean difference [MD] - 1.92 mmHg; 95% CI: - 41.06 to 37.20). Compared with the control group, esketamine showed more favorable intraoperative respiratory mechanics and lower opioid requirements. Furthermore, esketamine was associated with higher global QoR-15 scores at 24 h postoperatively compared with the Control group (adjusted MD 8.10; 95% CI 2.99 to 13.21) and the Dexmed group (adjusted MD 6.47; 95% CI 1.36 to 11.59). However, the incidence of postoperative pulmonary complications did not differ significantly among the groups (P = 0.86).

conclusionIntraoperative esketamine is non-inferior to dexmedetomidine for maintaining oxygenation during OLV. Furthermore, it was associated with lower perioperative opioid/anesthetic requirements and higher early postoperative recovery scores, although it did not significantly reduce clinical pulmonary complications.
