The effect of intravenous lidocaine infusion on subarachnoid anesthesia in patients undergoing total knee replacement: a randomised controlled trial.
Trial report in Journal of anesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeIntravenous lidocaine is a non-opioid analgesic adjunct for perioperative pain relief. The aim of our study was to explore whether concurrent administration of intravenous lidocaine prolongs the duration of sensory block during total knee replacement (TKR) under spinal anaesthesia.
methodsThis prospective randomized double blind controlled trial was conducted on 28 patients (14 in lidocaine group and 14 in the control group) undergoing unilateral TKR under spinal anesthesia. In the lidocaine group, intravenous lidocaine 1.5 mg·kg
resultsThe duration of sensory and motor block was longer in the lidocaine group (Mean ± SD; 112.50 ± 5.80 min versus 78.21 ± 9.12 min; p < 0.001 and 237.14 ± 9.14 min versus 215.00 ± 10.12 min; p < 0.001, respectively). Time to requirement of first rescue analgesia was 184.29 ± 9.38 min in the lidocaine group and 127.14 ± 23.35 min in the control group (p < 0.001). VAS scores were lower in the lidocaine group at 4, 8, 12 and 24 h after surgery (p < 0.00001, p < 0.00001, p < 0.00006, p = 0.032, respectively). Requirement of additional analgesia in the first 24 h was higher in the control group. There were no clinical signs to suggest lidocaine toxicity in any patient.
conclusionDuring unilateral TKR under spinal anaesthesia, concurrent use of intravenous lidocaine prolonged sensory block and reduced postoperative analgesic requirements.
