EasyThru Medical  PVC Laryngeal Masks/LMA Airway

Laryngeal mask airway (LMA), also known as laryngeal mask airway (LMA), is an artificial airway placed in the throat cavity, sealed with airbags between the esophagus and throat cavity, and ventilated through the throat cavity. It avoids tracheal intubation, but is more effective than using a mask.
According to its own characteristics and uses, laryngeal masks can be divided into four categories: ordinary laryngeal masks (used to maintain autonomous breathing during anesthesia), reinforced laryngeal masks (used to control breathing), intubation type laryngeal masks (auxiliary endotracheal intubation), and dual chamber laryngeal masks

Feature:

1. According to the human anatomy and physiology of the pharynx curved plastic design, easier to place and fixed.

2, Independent gastric drainage pathway, can reduce the risk of reflux aspiration, better protection of airway safety.

3, Smooth backplane design, inflatable balloon airway pressure up to 30cm and H2O, enhanced airway tightness.

4, The use of transparent silicone material, delicate, soft, good biocompatibility.

5, High-capacity inflatable balloon, can reduce the pressure on the hypopharyngeal mucosa, improve patient comfort and safety.

Advantages of laryngeal mask
1. The laryngeal mask can be disinfected with high-pressure steam and can be reused.

2. The operation is simple and easy, as long as the patient does not have difficulty opening their mouth, they can place the laryngeal mask, and it is easy to fix and not easy to detach.

3. Without mechanical stimulation such as insertion of a laryngoscope, exposure of the glottis, or insertion of a catheter through the glottis, complications such as laryngeal edema, vocal cord injury, and recurrent laryngeal nerve paralysis are less likely to occur.

4. Implantation has mild stimulation, minimal secretion, does not affect tracheal cilia activity, is conducive to sputum excretion, and can maintain the self-cleaning effect of the airway; Postoperative pulmonary complications such as cough, atelectasis, and pneumonia are rare.

5. The airway resistance is small, the patient's respiratory work is small, and the respiratory muscles are not easily fatigued.

6. The required depth of anesthesia is shallower than for tracheal intubation, and the amount of anesthesia used is reduced.

Typical Problems of Difficulty in Ventilation with Laryngeal Mask
1. During mechanical ventilation with laryngeal mask, the airway resistance exceeds 30 mmH2O, and the patient has no chest undulation and decreased blood oxygen.

Is the depth of anesthesia sufficient—— When the swallowing reflex is not suppressed, the epiglottis will block gas from the laryngeal mask from entering the trachea.

Is the degree of muscle relaxation sufficient—— After the metabolism of muscle relaxants is complete, the glottis is tightly closed, and the gas from the laryngeal mask cannot enter the trachea.

2. After inserting a laryngeal mask, mechanical ventilation was performed and a noticeable sound of air leakage was heard.
Is the laryngeal mask model chosen correctly? Have you adjusted the gas inside the laryngeal mask cuff? Has the patient's position changed?

Did you lift your head and chin when inserting the laryngeal mask-- When the patient is inserted, if there is no head pushing step or if the head is not pushed in place, it is easy to push the tongue back, partially or completely blocking the air outlet of the laryngeal mask, resulting in increased ventilation resistance and leakage of the laryngeal mask.
