Esketamine modulates postoperative biochemical markers of oxidative stress, inflammation, and immune dysregulation in laparoscopic colorectal cancer surgery.

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.

Abstract
Background: Laparoscopic colorectal cancer surgery, while minimally invasive, induces systemic oxidative stress, inflammation, and immune dysfunction through surgical trauma and anesthesia-related stress. Esketamine, an NMDA receptor antagonist with antioxidant and anti-inflammatory properties, may mitigate these biochemical perturbations. This study evaluated esketamine's effects on serum biomarkers of oxidative stress (glutathione, catalase, malondialdehyde, superoxide dismutase), inflammatory mediators (TNF-a, CRP IL-6), and T lymphocyte subsets in patients undergoing laparoscopic colorectal cancer resection. Methods: In this randomized controlled trial, 150 stage I-II colorectal cancer patients were allocated to esketamine (0.25 mg/kg bolus + 0.12 mg/kg/h infusion) or control (saline) groups during standardized anesthesia. Preand postoperative serum levels of oxidative stress markers (GSH, CAT, MDA, SOD), inflammatory cytokines (TNF-a, CRP IL-6), and immune cell subsets (CD3+, CD4+, CD8+, CD4+/CD8+ ratio) were quantified via ELISA and flow cytometry. Statistical analysis compared intergroup differences using t-tests and chi-square tests. Results: Postoperatively, the esketamine group exhibited significantly attenuated oxidative stress, with higher GSH (72.43± 6.63 vs. 60 .1 6± 5.57 mg/mL, P < 0.05), CAT (92.56± 8.31 vs. 82.81 ± 7.75 U/mL), and SOD (84.53± 8.02 vs. 69 .93± 7.05 nU/mL), alongside lower MDA (6.41± 0.52 vs. 9.52± 0.63 mmol/L). Pro-inflammatory cytokines were reduced (TNF-a: 4 0 .32 ± 4.84 vs. 54.37± 5.80 pg/mL; IL-6: 50.83± 5.05 vs. 82 .38± 8.46 pg/mL, P < 0.05). Immune function preservation was evident through elevated CD3+ (4 5 .1 8 ± 5 .0 1 % vs. 37 .05 ± 4.92% ) and CD4+ T cells (26.51 ±2.76% vs. 19.78± 2.09%), with a balanced CD4+/CD8+ ratio (1.12± 0.12 vs. 0.72± 0.09). Conclusions: Esketamine-based anesthesia significantly ameliorates postoperative oxidative damage, suppresses inflammatory cytokine release, and preserves cellular immune homeostasis, as evidenced by targeted biochemical and immunological analyses. These findings highlight esketamine's role in modulating perioperative biochemical pathways, potentially enhancing recovery in colorectal cancer surgery.
