Improvement in postoperative pain control by combined use of intravenous dexamethasone with dexmedetomidine after erector spinae plane block and serratus anterior plane block for thoracoscopic surgery: a randomized controlled trial.
Trial report in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundAcute pain after thoracoscopic surgery is very noticeable and often requires additional techniques or adjunctive medications to reduce it. We investigated whether intravenous dexamethasone with dexmedetomidine after erector spinae plane block and serratus anterior plane block could further decrease the incidence of moderate-to-severe pain.
methodsA total of 81 patients were randomly assigned to group C (20 mL normal saline), group S (10 mg dexamethasone + normal saline to 20 mL), or group SM (10 mg dexamethasone + 1 µg/kg dexmedetomidine + normal saline to 20 mL). All patients underwent erector spinae plane block and serratus anterior plane block 30 min before anesthesia induction and all drugs were infused intravenously 30 min after general anesthesia induction. The primary outcome was incidence of moderate-to-severe pain at 24 h on movement postoperatively. Secondary outcomes included incidence of moderate-to-severe pain on movement and at rest throughout the first two postoperative days, pain score, opioid consumption, quality of recovery and adverse effects.
resultsGroup SM lowered the incidence of moderate-to-severe pain on movement at 24 h postoperatively than group C (11.1% vs. 48.0%; RR 0.231; 95% CI, 0.074 to 0.725) and group S (11.1% vs. 38.5%; RR 0.289; 95% CI, 0.089 to 0.933). Group SM reduced NRS score on movement (3.0 [3.0] vs. 3.0 [2.0] vs. 3.0[1.0]; P < 0.001) and total opioid consumption (26.0 [6.0] vs. 32.0 [9.0] vs. 28.0 [2.5]; P = 0.004) within 24 h after surgery, fewer patients required rescue analgesia (11.1% vs. 48.0% vs. 38.5%; P = 0.009). Group SM also lowered incidence of nausea and vomiting (7.4% vs. 32.0% vs. 30.8%; P = 0.047) and had a higher QoR-15 score at postoperative 24 h (132.0 [10.0] vs. 123.0 [8.0] vs. 127.5 [10.8]; P < 0.001).
conclusionsIntravenous administration of dexamethasone with dexmedetomidine after erector spinae plane block and serratus anterior plane block further decreased the incidence of moderate-to-severe pain. It also reduced NRS scores and opioid consumption, making the postoperative pain control better for thoracoscopic surgery.
