Balloon laryngoscopy reduces head extension and blade leverage in patients with potential cervical spine injury.
Trial report in Critical care (London, England), 2000. 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
backgroundHead extension and excessive laryngoscope blade levering motion (LBLM) are undesirable during airway management of trauma patients. We hypothesized that laryngoscopy with a modified blade facilitating glottic exposure by balloon inflation would reduce head extension and LBLM. PATIENTS AND
methodsSeventeen elective surgery patients were enrolled. Patients lay supine with their heads flat on a rigid board and had a rigid collar around their necks. Laryngoscopy was performed with the modified blade and a standard curved blade. Head extension and LBLM angles were determined upon maximal glottic exposure and compared used paired t-tests. Laryngoscopic view grade and oxygen saturation were also determined.
resultsBalloon laryngoscopy resulted in less head extension and LBLM (P <0.001). Laryngoscopic view was approximately identical with both blades, and oxygen saturation was always above 97%.
conclusionsBalloon laryngoscopy reduces head extension and LBLM under simulated cervical spine precautions.
