Initial experience with surgical humidification to prevent tissue dehydration during pterional craniotomy for aneurysm clipping: illustrative case.

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
backgroundDuring craniotomy, brain tissues are exposed to the relatively cold and dry environment of the operating room. This, together with excess localized heat generated from the surgical microscope light, can lead to increased evaporation from the wound, tissue desiccation, and potential thermal injury to neural and vascular tissue. The authors describe their initial experience with the technique of surgical humidification during aneurysm clipping with minimal intracranial irrigation. OBSERVATIONS: The patient's intracranial tissue showed no visible signs of dehydration, even though no irrigation was used during the intradural dissection stages or aneurysm clipping. The surgical humidification device was easy to use and ergonomic, and it did not interfere with the surgeon's visualization, dissection, or clip application. The procedure was uneventful, and the patient did not experience any perioperative complications. LESSONS: While further investigation is needed to confirm the clinical impact of surgical humidification in neurosurgery, this therapy was safe and effective in this patient. Surgical humidification maintained intracranial tissue hydration and minimized the need for irrigation. https://thejns.org/doi/10.3171/CASE24685.
