What are supraglottic devices?
Supraglottic airways (SGAs) are a group of airway devices that can be inserted into the pharynx to allow ventilation, oxygenation, and administration of anesthetic gases, without the need for endotracheal intubation.
Is an LMA a supraglottic airway?
The laryngeal mask airway (LMA) is a supraglottic airway device developed by British Anesthesiologist Dr. Archi Brain. It has been in use since 1988.
How do you use a supraglottic airway device?
Classic technique for insertion of a laryngeal mask airway (LMA) device. With the neck flexed and the head extended by pushing the head from behind with one hand, the LMA is inserted into the mouth with the other hand (A).
When should you use a supraglottic airway?
Consider moving to a supraglottic airway early when an intubation attempt is unsuccessful, if the patient desaturates during an intubation attempt, or if chest compressions interfere with intubation attempts.
When are Lmas used?
Elective ventilation: The laryngeal mask airway (LMA) is often used for short surgical procedures in which endotracheal intubation is not necessary. Difficult airway: In some patients where endotracheal intubation fails, the LMA can be used as a rescue device for maintaining the airways.
What is the main disadvantage of a supraglottic airway?
Mild short-lasting adverse effects of the devices have significantly higher incidence than serious complications and involve postoperative sore throat, dysphagia, pain on swallowing, or hoarseness. Devices may have deleterious effect on cervical mucosa or vasculature depending on their cuff volume and pressure.
Is Combitube a supraglottic airway?
The esophageal tracheal combitube (ETC) is a supraglottic airway device that functions as an effective alternative to ventilation via mask and tracheal intubation and is therefore a valuable tool in difficult and emergency airway management.
What is the difference between a subglottic and a supraglottic device?
supraglottis which is situated between the base of tongue and the vocal cords, glottis composed of the vocal cords and the false vocal cords. subglottis which is a part of the larynx situated just below the vocal cords and upto the trachea.
Can nurses insert LMAs?
The LMA has been successfully used by nurses during cardiopulmonary resuscitation (Baskett, 1994). Ventilation using a bag/valve/LMA device is more efficient, and certainly easier, than the conventional bag/valve/mask device, and the incidence of regurgitation is lower (Resuscitation Council (UK), 2000).
How do I confirm my LMA placement?
After insertion, placement of the LMA was confirmed by clinical tests, ultrasound examination and fiberoptic laryngoscopy. Of the 64 women, placement was confirmed as acceptable in 89.1% by clinical tests, in 59.4% by fiberoptic laryngoscope assessment and in 67.2% by ultrasound examination.
What is an advantage of a supraglottic airway over an OPA?
This non-inflatable cuff has a number of potential advantages, including easier insertion, minimal risk of tissue compression, and stability after insertion (i.e. no position change with cuff inflation)1. It is not necessary to insert fingers into the mouth of the patient for full insertion.
