Effect of dexmedetomidine on the development of mechanical allodynia and central sensitization in chronic post-ischemia pain rats.
Article in Journal of pain research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeComplex regional pain syndrome type 1 (CRPS I) is an intractable neuropathic pain syndrome. Chronic post-ischemia pain (CPIP) model is an animal model of CRPS I which is produced by ischemia-reperfusion (IR) injury of the hind limb. Dexmedetomidine (DEX) is a selective and potent α2 adrenergic receptor agonist with analgesic and protective effects following an IR injury. We hypothesized that DEX protects the development of mechanical allodynia and central sensitization in CRPS I. Therefore, we evaluated the dose-related protective effect of DEX in a CPIP model.
methodsWe divided 45 rats into five groups: sham, CPIP, CPIP + DEX 10 µg/kg, CPIP + DEX 50 µg/kg, and CPIP + DEX 100 µg/kg. Rats in the sham group underwent sham surgery, and the other rats received CPIP injury. One hour before reperfusion or end of sham surgery, normal saline was injected into the rats in the sham and CPIP groups, and DEX (designated dose) was injected into the rats in the other groups. All rats were evaluated for the withdrawal threshold of both hind paws before surgery and 1, 3, and 7 days after surgery. Phosphorylation of
resultsAdministration of DEX before reperfusion showed a significant increase in the withdrawal threshold in both hind paws and a significant decrease of the expressions of pGluN1 and pERK in CPIP rats dose dependently (
conclusionDEX may inhibit the development of mechanical allodynia and central sensitization in CPIP rats.
