Laryngeal Mask Airway

Laryngeal Mask Airway (LMA)

1-The LMA-Classic™:



-It is a reusable LMA™ airway for general anesthesia.
-The LMA-Classic™ is available in eight sizes: (1, 1½, 2, 2½, 3, 4, 5, and 6).

Advantages:

-A safe and effective alternative to the endotracheal tube and the facemask.

-Over 100 million uses worldwide.

-Leaves the anesthetist's hands free to attend, to monitoring and record keeping.

-Latex-free and exceptionally well tolerated.

-A reusable device that can be cleaned and steam sterilized up to 40 times before being discarded.

2-LMA-Unique™ (Single-use):



-The LMA-Unique™ is a convenient, single-use LMA™ airway suitable for general anesthesia procedures.

-The LMA-Unique™ is available in sizes: (1, 1½, 2, 2½, 3, 4, and 5).

-The LMA-Unique™ is a disposable, single-use device, made to the same design specifications as the LMA-Classic™.

Advantages:

-Packaged sterile - ready for use.

-Suitable for use on emergency vehicles.

-Suitable where access to sterilization facilities is limited.

-Made of medical-grade PVC.

3-LMA-Flexible™:



-The LMA-Flexible™ is a reinforced LMA™ airway with a flexible airway tube.

-The LMA-Flexible™ is available in sizes: (2, 2½, 3, 4, 5, and 6).

-The LMA-Flexible™ is a re-usable device that can be cleaned and steam sterilized up to 40 times before being discarded.

Advantages:

-Designed for ENT, dental, and head surgery.

-Allows extreme flexion.

-Guaranteed kink and crush-proof.

-Latex-free.

4-LMA Flexible (Single-use):



-The LMA Flexible™ Single Use is ideal for use in ENT, ophthalmic, dental, and other head and neck cases and extends the LMA™ Airway benefits of hemodynamic stability and smoother emergence to more procedures.

5-LMA-ProSeal™:



-The LMA-ProSeal™ is an advanced LMA™ airway suitable for general anesthesia.

-It has a unique double cuff arrangement that provides an exceptionally effective, 'hands-free' airway seal, at low intracuff pressures.

-The LMA-Proseal™ is available in sizes: (1½, 2, 2½, 3, 4, and 5).

-The LMA-Proseal™ is a re-usable device that can be cleaned and steam sterilized up to 40 times before being discarded.

Advantages:

-A new double tube design separates the respiratory and alimentary tracts, providing a safe escape channel for regurgitated fluids in the event of unexpected regurgitation.

-The mask is designed to be a minimally stimulating airway device, whose cuff tip presses against the upper oesophageal sphincter when it is correctly positioned. The sides of the mask face the pyriform fossae and the upper border rests against the base of the tongue.

-Latex-free.

6-LMA Supreme™ (Single-use):



-The first and only single-use laryngeal mask with a built-in drain tube.
-The integrated drain tube is designed to channel fluid and gas safely away from the airway. Several simple and quick tests help verify accurate positioning.
-An improved curve for easy insertion. Subtle refinements in the mask make correct placement easier.

7-LMA Fastrach™ & LMA Fastrach™ ETT:



-The design of the LMA-Fastrach™ facilitates rapid insertion from any position, even if space is limited, and moving the patient is a possible hazard.

-The device is self-positioning with the rigid tube designed to fit the curvature of the palatopharyngeal arch, enabling a firm seal to be achieved.

-The LMA-Fastrach™ is available in sizes: (3, 4, and 5).

-The LMA-Fastrach™ is a reusable device that can be cleaned and steam sterilized up to 40 times before being discarded.

Advantages:

The LMA-Fastrach™ has additional features to those of the LMA-Classic™:

-Designed specifically for the anatomically difficult airway.

-Ideal in emergency situations.

-Can be used as an intubating tool, with no interruption of patient oxygenation.

-Allows insertion in the neutral position, in limited space.

-No need to move the patient.

-No need to insert fingers into the patient's mouth.

8-LMA Fastrach™ & LMA Fastrach™ ETT (Single-use):

9-LMA CTrach™:



-The only difficult airway device that allows ventilation, visualization, and intubation.

-The LMA CTrach™ is designed to increase intubation success rates in difficult airways. The LMA CTrach™ mask enables ventilation during intubation attempts while built-in fiber optics provide a direct view of the larynx and real-time visualization of the ET tube passing through the vocal cords.

-The LMA CTrach™ can be inserted exactly the same as the LMA Fastrach™, however, unlike the LMA Fastrach™, once the airway is secured and the patient is being ventilated, the viewer is switched on, placed in the magnetic connector, and a clear image of the larynx is displayed in real-time. The ET tube can be viewed as it enters the trachea. Once the patient is intubated, the viewer is removed and the mask is removed leaving the ET tube in place.

10-i-gel™:



-The i-gel supraglottic airway device accurately and naturally positions itself over the laryngeal framework to provide a reliable peri-laryngeal seal without the need for an inflatable cuff.

-i-gel is made from a medical-grade thermoplastic elastomer, i-gel has been designed to create a non-inflatable, anatomical seal of the pharyngeal, laryngeal, and peri-laryngeal structures whilst avoiding compression trauma.

-i-gel is currently available in sizes: (1, 1½, 2, 2½, 3, 4, and 5), and is supplied in an innovative, color-coded polypropylene ‘cage pack’.

Advantages:

-No inflatable cuff offers easy, rapid insertion.

-An integral bite block reduces the possibility of airway occlusion.

-A buccal cavity stabilizer aids rapid insertion and eliminates potential rotation.

-Made from a unique, soft, gel-like material to allow ease of insertion and reduced trauma.

-Gastric channel designed to improve and enhance patient safety.

-Reduces the possibility of epiglottis downfolding and obstructing the airway.

-Unique packaging protects the i-gel in transit and ensures that it maintains its anatomical shape.
