A two-dimensional model of anatomic relationships during laryngoscopy.
BACKGROUND The view obtained during direct laryngoscopy is only seen by a single anesthesiologist. The inability of instructors to observe the view poses problems for teaching the technique. The anatomic interactions affecting laryngoscopy are largely internal, hampering efforts to understand why some patients are unexpectedly difficult to intubate. In response, we have constructed a full scale...
متن کاملPrevisional space during direct laryngoscopy
The laryngoscope should displace oral soft tissues forward out of the operator's vision. Therefore, the space in front of the view may be critical for determining the laryngoscopic view. The aim was to investigate the difference in the previsional space during difficult versus easy laryngoscopy (EL).Under general anesthesia, digital photographs of the lateral view of the head and neck were take...
متن کاملAsystole following Reintubation during Suspension Laryngoscopy
Transient increase in heart rate and mean arterial pressure commonly occur during manipulation of the airway via direct laryngoscopy. This phenomenon is understood to be due to a sympathetic nervous system reflex causing an increase in plasma catecholamines. Rarely, severe bradycardia and possible asystole can occur following laryngoscopy. One previous report described asystole during suspensio...
متن کاملQuantifying Shape Deformations by Variation of Geometric Spectrum
This paper presents a registration-free method based on geometry spectrum for mapping two shapes. Our method can quantify and visualize the surface deformation by the variation of Laplace-Beltrami spectrum of the object. In order to examine our method, we employ synthetic data that has non-isometric deformation. We have also applied our method to quantifying the shape variation between the left...
متن کاملHead-elevated laryngoscopy position: improving laryngeal exposure during laryngoscopy by increasing head elevation.
STUDY OBJECTIVE The objective of this study was to determine the effect of increasing head elevation and neck flexion on the quality of laryngeal view during laryngoscopy. METHODS Laryngoscopy with a straight blade was performed on 7 fresh human cadavers. Laryngeal views were recorded with the direct laryngoscopy video system, and the laryngoscopy angle was measured throughout the procedure w...
