Dexmedetomidine leads to the amelioration of stress response to surgery.
Article in Pakistan journal of medical sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Objectives: To determine the impact of intravenous Dexmedetomidine (Dex) administered perioperatively on stress response markers in patients undergoing ENT surgeries. Methods: This randomized interventional study was conducted at POFs Hospital and NUMS affiliated WMC, Wah Cantt, in collaboration with IIMC Rawalpindi, Pakistan, from October 2021 to April 2022. One hundred patients aged between 15-60 years, after satisfying the inclusion standards were randomly divided into two groups C and D. Group-C (n=50) received normal saline in addition to the standard anesthesia protocol. The intervention Group-D (n=50) was administered 1µg/kg dexmedetomidine hydrochloride intravenously over 10 minutes just before the induction followed 0.5μg/kg/hr as maintenance dose till the end of surgery. Serum inflammatory biomarkers (interleukins-6, TNF-α and cortisol) were measured in blood samples in both groups, taken at 0 (T0), 30 minutes(T1), and two hours (T2) time intervals and analyzed by using Enzyme-linked immunosorbent assay (ELISA). Data was statistically analyzed using SPSS 23. Results: The patients receiving Dex showed marked decrease in serum levels of cortisol, TNF- α and interleukins-6, from 139.73 to10.18, 99.51 to 0.96 and 85.09 to 0.96 respectively. Comparison between C and D groups revealed significant differences (p≤0.05) in these serum biomarkers. Conclusions: In the present study, intravenous Dex suppressed the intraoperative rise in levels of cytokine secretion and enhanced smooth recovery with no incidence of nausea and vomiting. These effects could be attributed to the anti-inflammatory effects of dexmedetomidine.
