Effect of intravenous lidocaine on nociception level-directed management in robot-assisted laparoscopic radical prostatectomy: protocol for a single-centre, factorial-randomised controlled trial (VALINOR study).

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
Study Objective: To evaluate the efficacy of intra-operative lidocaine administration combined with nociception level-guided opioid management and to compare two minimum remifentanil infusion rate limits (0.11 vs. 0.05 μg.kg Design: Single-centre, double-blinded, two-by-two factorial randomised controlled trial. Setting: Operating theatres at Nara Medical University Hospital, Nara, Japan. Participants: Eighty-four adult patients scheduled for elective robot-assisted radical prostatectomy were participated in the study. Interventions: Participants will be randomised into four groups (lidocaine/0.11, lidocaine/0.05, placebo/0.11 and placebo/0.05). All groups will receive nociception level-guided intra-operative opioid management. Measurements: The primary outcome is the numerical rating scale score during movement 2 hours after surgery. Secondary outcomes include plasma concentrations of peri-operative inflammatory biomarkers (interleukin-6, cortisol and C-reactive protein), intra-operative remifentanil consumption, Quality of Recovery-15 scores (pre-operative and postoperative days 1 and 2), postoperative numerical rating scale scores up to postoperative day 7, peri-operative fentanyl consumption and the presence of prolonged postoperative pain at 3 months. Hypothesis: Lidocaine will decrease intra-operative remifentanil requirements and early postoperative pain without increasing the inflammatory biomarker levels and the minimum remifentanil infusion rate limit will not significantly impact clinical outcomes. Conclusion: This trial will evaluate the effects of intra-operative lidocaine administration and minimum remifentanil infusion rate limit based on nociception level-guided opioid management in patients undergoing robot-assisted radical prostatectomy. Trial Registration: Japan Registry of Clinical Trials, jRCTs052240226 (registered on 26 December 2024, https://jrct.mhlw.go.jp/latest-detail/jRCTs052240226). Ethics Approval: This protocol was approved by the Certified Review Board of Nara Medical University on 11 December 2024 (nara0063). Study Period: Recruitment is planned from January 2025 to December 2026, with final follow-up completed in March 2027.
