Ultrasound-guided unilateral thoracic paravertebral block for postoperative analgesia in pediatric patients undergoing thoracoscopic mediastinal tumor resection: a single-center randomized controlled trial.
Trial report in World journal of surgical oncology, 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
backgroundThoracic paravertebral block (TPVB) has rarely been reported for pediatric mediastinal tumor surgery. This study aimed to evaluate the efficacy of unilateral TPVB for postoperative analgesia in children undergoing thoracoscopic mediastinal tumor resection, providing a potential option for multimodal analgesia in pediatric thoracic oncology surgery.
methodsChildren aged 4 to 12 years scheduled for thoracoscopic mediastinal tumor resection were enrolled and randomly assigned to either the general anesthesia group (GA group) or the general anesthesia combined with paravertebral block group (TPVB group). Postoperative pain was assessed using the FLACC (Face, Legs, Activity, Cry, Consolability) scale at 2, 4, 8, 12, and 24 h after surgery. The primary outcome was the pain intensity, and secondary outcomes included pain scores at rest and during activity, postoperative opioid consumption, adverse events, and recovery quality.
resultsOf the 120 patients enrolled and randomized, 110 completed the study (GA group, n = 54; TPVB group, n = 56).Results showed that the TPVB group had significantly lower pain intensity compared to the general anesthesia group (1.8 ± 0.3 vs. 2.2 ± 0.3, p < 0.001). Pain scores at rest and during activity were significantly reduced at 2, 4, and 8 h, and pain scores at rest remained significantly lower at 12 h. Compared with the GA group, the TPVB group had lower postoperative opioid consumption (0.2 [0.1–0.3] µg/kg vs. 0.3 [0.2–0.4] µg/kg, p = 0.024), a lower incidence of desaturation in the post‑anesthesia care unit (PACU) (2 [3.6%] vs. 12 [22.2%], p = 0.003), shorter PACU stay (21 [15–27] min vs. 31 [25–35] min, p < 0.001), earlier chest tube removal (3 [3–4] days vs. 4 [3–4] days, p = 0.013), and a shorter hospital stay (5 [4–6] days vs. 6 [5–7] days, p < 0.001). There were no significant differences in adverse events between the two groups.
conclusionUnilateral TPVB for pediatric mediastinal tumor resection significantly reduces overall pain intensity within 24 h and pain scores within the first 8 h postoperatively, decreases opioid consumption during the first 24 h, and improves postoperative recovery.
