Ultrasound-Guided Superior Laryngeal Nerve Block Combined with Cricothyroid Membrane Puncture for Awake Tracheal Intubation in a Patient with a Laryngeal Tumor: A Case Report and Literature Review.
Article in International medical case reports journal, 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: Airway management for laryngeal tumor surgery is challenging because conventional induction of general anesthesia may worsen dynamic obstruction, whereas prophylactic tracheostomy is more invasive. We describe a minimally invasive awake airway strategy using ultrasound-guided superior laryngeal nerve block (SLNB) combined with cricothyroid membrane puncture. Case Presentation: A 59-year-old man with a laryngeal tumor, hypertension, diabetes mellitus, and coronary artery stenosis underwent successful awake flexible bronchoscopy-guided tracheal intubation after ultrasound-guided bilateral SLNB combined with cricothyroid membrane puncture, with a front-of-neck surgical airway prepared as backup. At predefined peri-intubation time points, systolic/diastolic blood pressure ranged from 131-183/68-102 mmHg, heart rate from 44 to 78 beats/min, respiratory rate from 14 to 22 breaths/min, and SpO Conclusion: In selected patients with high-risk laryngeal tumors, ultrasound-guided SLNB combined with cricothyroid membrane puncture may facilitate awake tracheal intubation while avoiding unnecessary surgical airway creation. This technique may serve as a useful alternative when conventional induction is considered hazardous.
