Official title
Comparison of 3 Direct Laryngoscopes: Inscope DL Blade Size 3.5 and DL Blade 3.5 Sun-Med GreenLine®/D™ to DL Blade 3 Sun-Med GreenLine®/D™ for Tracheal Intubation in Patients Undergoing Lumbar Spine Surgery, a Prospective Randomized Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Hypothesis The use of Macintosh blade sized #3.5 (vs Macintosh size #3) would reduce the time required to achieve successful tracheal intubation and improve the glottic view. Study objective The purpose of this research study is to compare 3 different laryngoscope blades (sizes: 3.5, 3.5 and 3) and see if the blades size 3.5 will reduce the time required to achieve successful tracheal intubation and improve the physician's view of the glottis compared to the standard direct laryngoscope using the blade size 3, in patients undergoing lumbar surgery. Primary end point: time to achieve successful tracheal intubation. Secondary end points: glottic view at intubation, number of intubation attempts and effectiveness of the integrated suction in the Inscope Direct Laryngoscope.
