Effects of esketamine-based opioid-sparing anesthesia protocol in Bama miniature pigs undergoing robot-assisted nephrectomy.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The safety and efficacy of the esketamine-based opioid-sparing anesthesia protocol, though validated, are understudied in robotic surgeries. This study used robot-assisted nephrectomy in Bama miniature pigs to explore its application. Six healthy Bama miniature pigs were randomly assigned to esketamine group (K) and control group (C). In Group K, based on the anesthetics of Group C, 0.5 mg/kg esketamine was used for anesthesia induction, and anesthesia was maintained with 0.5 mg/kg·h esketamine. Results showed Group K exhibited more stable hemodynamics intraoperatively, particularly at 5 min after the start of surgery and at the time of extubation (p < 0.05). Dosages of propofol (250 ± 8.7 mg vs. 347 ± 6.1 mg), sufentanil (12.3 ± 0.6 µg vs. 25 ± 1.0 µg) and remifentanil (498.3 ± 27.5 µg vs. 828.3 ± 20.2 µg) in group K were significantly reduced(p < 0.001). Recovery times for eyelid reflex (22.0 ± 2.0 min vs. 28.0 ± 2.6 min), extubation (24.7 ± 2.5 min vs. 32.3 ± 2.5 min), and righting reflex (37.7 ± 2.5 min vs. 48.7 ± 5.5 min) were significantly shorter in group K (p < 0.05). In conclusion, the esketamine-based opioid-sparing anesthesia protocol can be safely and effectively used in Bama miniature pigs undergoing robot-assisted nephrectomy.
