We\n\t\t\t\thypothesized that laryngoscopy with a modified blade facilitating glottic\n\t\t\t\texposure by balloon inflation would reduce head extension and LBLM.\n        \n        \n          Patients and methods:\n          Seventeen elective surgery patients were enrolled. Patients lay\n\t\t\t\tsupine with their heads flat on a rigid board and had a rigid collar around\n\t\t\t\ttheir necks. Laryngoscopy was performed with the modified blade and a standard\n\t\t\t\tcurved blade. Head extension and LBLM angles were determined upon maximal\n\t\t\t\tglottic exposure and compared used paired t-tests. Laryngoscopic view\n\t\t\t\tgrade and oxygen saturation were also determined.\n        \n        \n          Results:\n          Balloon laryngoscopy resulted in less head extension and LBLM\n\t\t\t\t(P <0.001). Laryngoscopic view was approximately identical with\n\t\t\t\tboth blades, and oxygen saturation was always above 97%.\n        \n        \n          Conclusions:\n          Balloon laryngoscopy reduces head extension and LBLM under\n\t\t\t\tsimulated cervical spine precautions.", "distribution": [{"@type": "dcat:Distribution", "description": "Visit the original government dataset for complete information, documentation, and data access.", "downloadURL": "https://www.ncbi.nlm.nih.gov/pmc/articles/PMC29034/", "mediaType": "text/html", "title": "Official Government Data Source"}], "identifier": "https://healthdata.gov/api/views/a44t-rhyf", "issued": "2025-07-13", "keyword": ["airway-management", "cervical-spine-injury", "glottic-exposure", "laryngoscopy", "nih"], "landingPage": "https://healthdata.gov/d/a44t-rhyf", "modified": "2025-09-06", "programCode": ["009:048"], "publisher": {"@type": "org:Organization", "name": "National Institutes of Health"}, "theme": ["NIH"], "title": "Balloon laryngoscopy reduces head extension and blade leverage in\n\t\t  patients with potential cervical spine injury"}
