Pre-emptive Dexmedetomidine Versus Magnesium Sulfate for Postoperative Analgesia in Nasal Surgery: A Prospective Comparative Study.
Article in Cureus, 2026. 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
BACKGROUND AND
objectiveDexmedetomidine and magnesium sulfate are commonly used during nasal surgery to provide controlled hypotension. This study compared their effects on postoperative analgesia. The primary outcome was postoperative pain assessed using the Visual Analogue Scale (VAS). Secondary outcomes included hemodynamic parameters, time to first rescue analgesic and total rescue analgesic consumption, and patient satisfaction. MATERIALS AND
methodsThis prospective, non-randomized comparative study included 75 patients with American Society of Anesthesiologists (ASA) physical status I-II undergoing nasal surgery under general anesthesia. Eligible patients were enrolled consecutively and observed across three exposure groups of 25 each, categorized according to the adjuvant selected by the treating anesthesiologist as part of routine clinical practice. Group D received a dexmedetomidine 0.5 µg/kg IV bolus administered over 10 minutes, 15 minutes before induction, followed by an infusion at 0.25 µg/kg/hour from induction until 15 minutes before the end of surgery. Group M patients received magnesium sulfate 40 mg/kg diluted in 100 mL normal saline administered IV over 15 minutes before induction, while group C received no anesthetic adjuvants and served as controls. We recorded VAS scores, hemodynamic variables, and rescue analgesics at predefined intervals up to 24 hours postoperatively. RESULTS AND
conclusionPostoperative VAS scores were significantly lower with dexmedetomidine than with magnesium sulfate at one to two hours (0.64±0.76 vs 2.04±0.84; 1.24±0.78 vs 2.60±1.47; p <0.001), and both groups were lower than controls in the first six hours (p <0.05). Time to first rescue analgesia was longer with dexmedetomidine (285±46.63 min) than with magnesium sulfate (147.27±49.21 min; p <0.001), with lower analgesic consumption and higher patient satisfaction (p <0.001). Pre-emptive dexmedetomidine was associated with improved postoperative analgesia and reduced rescue analgesic requirement after nasal surgery.
