Frequent question: Is an LMA a secure airway?

The laryngeal mask airway (LMA) provides a safe and effective method of securing an airway in anesthesia and critical care settings.

Can you paralyze with LMA?

It isn’t safe to paralyze a patient with a supraglottic device (SGA) Page 53 Page 54 Paralysis & SGAs The belief is that PPV under paralysis with an LMA will “force” any gastric contents which could come up INTO the trachea and result in aspiration.

When should you not use an LMA?

Contraindications include morbidly obese individuals, pregnant women > 14 weeks gestation, individuals at increased risk for aspiration, patients in which peak inspiratory pressures may exceed 20 cm H20. Remove the single use LMA from the packaging and inspect the device.

How long can you use an LMA?

D. The laryngeal mask airway (LMA) has been used successfully in numerous cases since its introduction more than 30 years ago. While some contraindications to LMA use are absolute others are less well defined. An upper time limit of three hours has been recommended for patients whose airway is managed with an LMA.

What is the difference between LMA and ETT?

The LMA has many advantages over the ETT, such as having no direct contact with the tracheal mucosa, no need for direct laryngoscopy during inserting, and less adverse events such as lower frequency of coughing and decreased oxygen saturation during emergence, and lower incidence of sore throat in adults [6].

What is LMA used for?

Laryngeal mask airways (LMA) are supraglottic airway devices. They may be used as a temporary method to maintain an open airway during the administration of anesthesia or as an immediate life-saving measure in a patient with a difficult or failed airway.

What are the types of LMA?

Laryngeal mask airways come in several types, as follows: The LMA Classic is the original reusable design. The LMA Unique is a disposable version, making it ideal for emergency and prehospital settings. The LMA Fastrach, an intubating LMA (ILMA), is designed to serve as a conduit for intubation.

Is a King airway and LMA?

As a “blind” airway device, the King Airway has largely replaced the Combitube as the civilian and military SGA of choice due to its design and ease of use. However, over the past decade, there have been many other SGAs, particularly iterations of the laryngeal mask airway (LMA), that have come to market.

Can you use a ventilator with an LMA?

Ventilation of nonparalyzed patients with LMA under anesthesia with PC-VG is advantageous over VCV in reducing PIP and increasing lung compliance. No difference was noted between PCV and PC-VG in ASA I or II under the adequate depth of anesthesia in patients with normal pulmonary function.

What is a LMA in anesthesia?

Laryngeal Mask Airway (LMA) – When possible, the anesthesiologist will use a Laryngeal Mask Airway device instead of intubation because it is quicker and causes less discomfort for the patient. An LMA is a tube with an inflatable cuff that is inserted into the pharynx (the upper part of the windpipe).
