supraglottic การใช้
- Other signs and symptoms include fever and facial and supraglottic edema.
- It is a type of supraglottic airway.
- In roughly increasing order of invasiveness are the use of supraglottic devices such as surgical methods.
- The Supraglottic area including epiglottis, arytenoids and false cords are usually involved due to their rich lymphatic supply.
- Supraglottic devices ensure patency of the upper respiratory tract without entry into the trachea by bridging the oral and pharyngeal spaces.
- Supraglottic techniques use devices that are designed to have the distal tip resting above the level of the glottis when in its final seated position.
- Examples in increasing order of invasiveness include the use of supraglottic devices such as oropharyngeal or nasopharyngeal airways, infraglottic techniques such as tracheal intubation and finally surgical methods.
- "Extraglottic devices " are another family of supraglottic devices that are inserted through the mouth to sit on top of the larynx " ."
- Advanced techniques require specialized medical training and equipment, and are further categorized anatomically into supraglottic devices ( such as surgical methods ( such as cricothyrotomy, and tracheotomy ).
- American and Canadian guidelines strongly recommend the use of supraglottic secretion drainage ( SSD ) Special tracheal tubes with an incorporated suction lumen as the EVAC tracheal tube form Covidien / Mallinckrodt can be used for that reason.
- Laryngeal cancer begins in the larynx or " voice box . " Cancer may occur on the vocal folds themselves ( " glottic " cancer ), or on tissues above and below the true cords ( " supraglottic " and " subglottic " cancers respectively ).
- "The supraglottic resonators being in the main muscular and moveable structures must be voluntarily controlled to produce conditions of optimal resonance either by varying degrees of tension in their walls, or by alterations in the size of their orifices and cavities during the articulatory movements ."
- In general, features of an ideal supraglottic airway include the ability to bypass the upper airway, produce low airway resistance, allow both positive pressure as well as spontaneous ventilation, protect the respiratory tract from gastric and nasal secretions, be easily inserted by even a nonspecialist, produce high first-time insertion rate, remain in place once in seated position, minimize risk of aspiration, and produce minimal side effects.
- Current evidence suggests that for out-of-hospital cardiac arrest, basic airway interventions ( head-tilt chin-lift maneuvers, bag-valve-masking or mouth-to-mouth ventilations, oropharyngeal airways ) resulted in greater short-term and long-term survival, as well as improved neurological outcomes in comparison to advanced airway interventions ( endotracheal intubation, laryngeal mask airway, all types of supraglottic airways ( SGA ), and trans-tracheal or trans-cricothyroid membrane airways ).
