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

Purpose: Non-intubated video-assisted thoracic surgery (NIVATS) reduces airway trauma but may lead to postoperative hyperalgesia and opioid dependence, contradicting enhanced recovery after surgery (ERAS) principles. We hypothesized that combining low-dose esketamine with a paravertebral block (PVB) may mitigate hyperalgesia, decrease opioid requirements, and improve recovery quality in NIVATS. Patients and Methods: This prospective single-center, double-blind randomized controlled trial (RCT) enrolled 82 patients undergoing uniportal NIVATS. Patients were randomized into two groups: esketamine (0.25 mg/kg pre-induction + 0.15 mg/kg/h intraoperatively) and control. Both groups received ultrasound-guided T4 and T6 PVB (with 0.375% ropivacaine). The primary outcome was mechanical pain threshold (MPT; central/peripheral), quantified preoperatively and at 0.5-48 h postoperatively using pressure algometry after laryngeal mask airway (LMA) removal. Secondary outcomes included quality of recovery-40 (QoR-40) scores, intraoperative sufentanil/norepinephrine use, postoperative rescue analgesia use, and other related complications. Results: Compared to controls, the esketamine group exhibited significantly higher MPT at 6 h postoperatively (central: 2.77 ± 0.80 vs 2.17 ± 0.59 kgf/cm², Conclusion: Low-dose esketamine combined with PVB attenuates postoperative hyperalgesia, reduces intraoperative opioid use by 71.4%, and enhances recovery in NIVATS, offering a clinically effective opioid-sparing strategy for ERAS protocols.
