Asystole during suspension laryngoscopy associated with vagal reflex or carotid sinus hypersensitivity: a case report.
Article in Journal of medical case reports, 2025. 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
backgroundAsystole during suspension laryngoscopy is a rare but potentially life-threatening complication if not promptly identified and treated. CASE PRESENTATION: A 62-year-old Vietnamese man developed sudden asystole during the insertion of a suspension laryngoscope for microlaryngeal surgery. The event was immediately recognized and rapidly reversed through prompt removal of the instrument, initiation of external chest compressions, and administration of intravenous atropine. Vagal reflex triggered by laryngeal stimulation was identified as the likely cause. However, carotid sinus hypersensitivity may have either contributed in conjunction with the vagal reflex or constituted an independent etiology.
conclusionThis case highlights that gentle surgical manipulation and avoidance of excessive cervical extension may help prevent severe bradycardia or asystole during suspension laryngoscopy. Vigilant monitoring and readiness for resuscitation remain essential for patient safety during suspension laryngoscopy.
