Physicochemical Stability of an S-Ketamine-Dexmedetomidine Anesthetic Mixture: An In Vitro 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 Although anesthetic drug admixtures are widely used in clinical practice, the physicochemical stability and photodegradation profile of the S-ketamine-dexmedetomidine (KET-DEX) admixture have not been previously characterized. This study evaluated the physicochemical stability of the KET-DEX admixture under ambient and ultraviolet (UV) light exposure. Methods The admixture (0.25 mM) was stored under ambient conditions or exposed to UV light for 24 hours. Physicochemical stability was assessed by high-performance liquid chromatography with diode-array detection (HPLC-DAD), while degradation products were characterized using mass spectrometry. Stability was evaluated based on chromatographic profile, degradation products, and physicochemical parameters. Results The KET-DEX admixture remained physicochemically stable for 24 hours under ambient conditions, with no evidence of significant degradation or drug interaction. In contrast, UV exposure induced progressive photodegradation of KET, whereas DEX remained stable. Conclusions The KET-DEX admixture demonstrated physicochemical stability under standard laboratory conditions but should be protected from UV light during storage and handling. These findings provide the first evidence of the admixture's stability profile and establish a foundation for future investigations addressing its clinical applicability, efficacy, and safety.
