Anatomical parts seen during laryngoscopy. Direct laryngoscopy is carried out (usually) with the patient lying on their back; the laryngoscope is inserted into the mouth on the right side and flipped to the left to trap and move the tongue out of the line of sight, and, depending on the type of blade used, inserted either anterior or posterior to the epiglottis and then lifted with an upwards ...
For example, in out-of-hospital cardiac arrest (OHCA), vomiting and regurgitation have a reported incidence of 20–30%. [ 2 ] [ 3 ] The traditional approach to the contaminated airway involves suctioning the airway and repositioning the patient, which can effectively manage airway soiling in many, but not all, cases.
Flexible Endoscopic Evaluation of Swallowing with Sensory Testing (FEESST), or laryngopharyngeal sensory testing, is a technique used to directly examine motor and sensory functions of swallowing so that proper treatment can be given to patients with swallowing difficulties to decrease their risk of aspiration (food and liquids going into the lungs instead of the stomach) and choking.
Laryngotracheal stenosis (Laryngo-: Glottic Stenosis; Subglottic Stenosis; Tracheal: narrowings at different levels of the windpipe) is a more accurate description for this condition when compared, for example to subglottic stenosis which technically only refers to narrowing just below vocal folds or tracheal stenosis.
For example, this procedure cannot be used when there is complete separation of the tracheo-esophageal wall where the puncture would otherwise be placed (for example, in case a portion of the esophagus is removed requiring an anastomosis, or “reconnection” of structures in the region).
Laryngoscope handles with an assortment of Miller blades (large adult, small adult, child, infant and newborn) Laryngoscope handle with an assortment of Macintosh blades (large adult, small adult, child, infant and newborn) Laryngoscopy. The vast majority of tracheal intubations involve the use of a viewing instrument of one type or another.
He invented a laryngoscope in 1854 and the next year published observations of his own larynx and vocal cords made with a small dental mirror introduced into the throat and using sunlight reflected by another mirror. [3] [4] He has been credited with saving the career of Jenny Lind, who had suffered vocal damage from overwork in her early ...
He also found that the lamina propria monolayer at birth and shortly thereafter was hypercellular, thus confirming Hirano's observations. By 2 months of age, the vocal fold started differentiating into a bilaminar structure of distinct cellular concentration, with the superficial layer being less densely populated than the deeper layer.
