The preventive effects of dexmedetomidine on endotoxin-induced exacerbated post-incisional pain in rats.

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
purposeLow-grade endotoxin (lipopolysaccharide; LPS) exposure may contribute to the development of exaggerated acute postoperative pain. In the present study, we investigated the possible impact of intraoperative administration of dexmedetomidine (DEX) on LPS-induced postoperative hyperalgesia in a rat incisional pain model.
methodsThe surgical and sham-surgical animals were randomly divided into saline-treated control, 5.0 mg/kg LPS-treated, 10 µg/kg DEX-treated, and 5.0 mg/kg LPS + 10 µg/kg DEX-treated groups. In the surgical animals, a 1-cm-long plantar incision was made through the skin and fascia under isoflurane anesthesia. The sham-surgical rats were only anesthetized. All treatments were administered by a single intraperitoneal (i.p.) injection 60 min before surgery. Acute postoperative pain was assessed using the Rat Grimace Scale (RGS) one day before surgery (baseline) and at 2 h post incision. In another experiment, the involvement of the α
resultsIn the sham-surgical animals, the RGS did not increase at 2 h after sham surgery compared with the corresponding baseline values in all groups. In the surgical rats, however, the postoperative RGS value of the LPS group was significantly higher than the control group, indicating LPS-induced postoperative hyperalgesia. Administration of intraoperative DEX could prevent the development of such LPS-induced exacerbated post-incisional pain. In addition, the preventive effects of intraoperative DEX were inhibited by pretreatment with atipamezole.
conclusionOur findings indicate that intraoperative DEX treatment can prevent LPS-induced exacerbated post-incisional pain via the α
