Combination of different local anesthetic adjunct for supraclavicular brachial plexus block after arthroscopic shoulder surgery: a prospective randomized controlled trial.
Trial report in BMC musculoskeletal disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 is a major concern after arthroscopic shoulder surgery, supraclavicular brachial plexus blockade has shown favorable postoperative analgesic effects. However, its duration of analgesia does not meet clinical needs. We aimed to explore whether the combination of different local anesthetic adjunct can prolong the analgesic duration of supraclavicular brachial plexus block for arthroscopic shoulder surgery.
methodsIn this prospective randomized controlled trial, we allocated 80 patients into four groups: Group DMD (dexamethasone 10 mg + ropivacaine 100 mg + dexmedetomidine 50 µg + magnesium sulfate 250 mg), Group DM (ropivacaine 100 mg + dexmedetomidine 50 µg + magnesium sulfate 250 mg), Group M (ropivacaine 100 mg + magnesium sulfate 250 mg) and Group D (ropivacaine 100 mg + dexmedetomidine 50 µg). The primary outcome was the time to first request for analgesia. Secondary outcome measures included cumulative opioid consumption at 6, 12, 18, 24, and 48 h postoperatively, VAS scores at 6, 12, 18, 24, and 48 h postoperatively and so on.
resultsThe time to first request for analgesia in Group DMD was significantly longer than Group DM (P = 0.011) and Group M (P = 0.003). The cumulative opioid consumption at 18 h postoperatively in Group DMD was significantly lower than in Group DM (P = 0.002) and Group M (P = 0.007). The cumulative opioid consumption at 24 h postoperatively in Group DMD was significantly lower than in Group DM (P = 0.016). The VAS score at 6 h postoperatively in Group DMD was significantly lower than in Group DM and Group M. The VAS score at 12 h postoperatively in Group DMD was significantly lower than in Group M. For American Shoulder and Elbow Surgeons Score, Group DMD had a better score than Group DM and Group D.
conclusionsThe analgesic efficacy of supraclavicular brachial plexus blockade combined with dexamethasone, magnesium sulfate, and dexmedetomidine is significantly superior to the combination of magnesium sulfate and dexmedetomidine, and significantly superior to the use of magnesium sulfate alone.
