Inflatable Laryngeal Mask

Inflatable Laryngeal Mask is an artificial airway that is placed in the laryngeal cavity and ventilated through the laryngeal cavity with air sacs. This avoids intubation, but is more effective than a mask.

Indications for Inflatable Laryngeal Mask

1.Surgery without the risk of vomiting and reflux, especially for patients with difficulty in tracheal intubation.

2.Laryngeal mask (LMA) can be used as a guide for endotracheal intubation after difficult intubation.

3.The laryngeal mask can be used to perform the operation of laser cauterization of vocal cords, trachea or small tumors in the bronchus by fiber optic bronchoscope.

4.Laryngeal mask can be used for patients with unstable cervical spine who need to move their head for intubation but have great concerns.

5.Laryngeal mask is suitable for ophthalmic surgery, which is less likely to cause intraocular pressure increase and less likely to cause coughing and vomiting after operation. The reaction of laryngeal mask pulling out is less and the fluctuation of intraocular pressure is less.

6.emergency resuscitation can use laryngeal mask, such as skilled operation can quickly establish effective ventilation, the effect is exact.

7.It is suitable for general anesthesia of body surface and limbs without muscle relaxation.

Inflatable Laryngeal Mask contraindications

(1) Absolute taboo

1.Patients with no fasting and delayed gastric emptying.

2.Risk of reflux and aspiration: such as hiatal hernia, pregnancy, intestinal obstruction, acute abdomen, thoracic injury, severe trauma, and a history of gastric contents reflux.

3.Airway obstruction that may occur after anesthesia in patients with tracheal compression and tracheal malacia.

4.Obesity, oropharyngeal disease and COPD, pregnancy over 14 weeks.

5.Small mouth opening, laryngeal mask can not pass.

(2) Relative taboo

1. Patients with low lung compliance or high lung resistance: Such patients usually have positive pressure ventilation (25 ~ 30cmH2O), and often suffer from air leakage around the ventilation hood and anesthesia gas entering the stomach.

2.Throat lesions: patients with throat abscess, hematoma, edema, tissue injury and tumor. Laryngeal lesions may lead to upper respiratory tract obstruction when present.

3.The respiratory tract is not easily accessible or some special positions: such as prone lying, side lying and requiring the anesthesiologist to stay away from the operating table. Physicians may not immediately intubate or perform other procedures due to displacement or prolapse of the LMA and vomiting and reflux.

The structure of Inflatable Laryngeal Mask

Inflatable Laryngeal Mask includes an inflatable cyst, a connecting catheter, a connector, and a catheter to inflate the cyst. It can be divided into straight type and pre-bent type. Choose the right size laryngeal mask according to the patient's weight. Before placement, a 20-40ml syringe (for inflating the sac), lubricant and tape are also required.

Types of Inflatable Laryngeal masks

According to its own characteristics and uses, laryngeal mask can be divided into four categories: general laryngeal mask (used to maintain spontaneous breathing during anesthesia), enhanced laryngeal mask (used to control breathing), intubated laryngeal mask (auxiliary endotracheal intubation) and double cavity laryngeal mask.

Common Inflatable Laryngeal Mask: It can be classified into eight models according to size (1, 1.5, 2, 2.5, 3, 4, 5, and 6). It is not recommended for prolonged use due to the risk of gas leakage during positive pressure ventilation, including flatulence, reflux, and aspiration.

Inflatable Laryngeal Mask: The inflatable laryngeal mask is flexible and less angulated than the conventional laryngeal mask, thus reducing the risk of airway blockage. It is mainly used for mechanical ventilation in eye, nose, throat, cranial, and oral surgery. There are currently six models: No. 2, No. 2.5, No. 3, No. 4, No.5 and No. 6 are suitable for the same crowd as the ordinary laryngeal mask.

Inflatable Laryngeal Mask: with fixed curvature and large internal diameter, inflatable laryngeal mask can pass through the tracheal catheter, and the number of laryngeal mask determines the thickness of the tracheal catheter that can be inserted. Available in 3 models, No. 3 and No. 4 laryngeal masks can pass through a tracheal tube with ID 6.0 mm, and No. 5 laryngeal masks can pass through a tracheal tube with ID 7.0 mm, mainly for patients with unexpected or anticipated difficulties in intubation.

The dual-cavity Inflatable Laryngeal Mask is characterized by the improvement of ventilator and the increase of drainage tube. After placement, two sealing cavities were formed, one connecting the laryngeal seal with the ventilation tube, and the other connecting the upper esophageal sphincter opening with the drainage tube by the front end of the ventilator. Compared with the common laryngeal mask, the insertion difficulty is similar, but positive pressure ventilation is safer and more effective, and the incidence of aspiration is lower. At the same time, the suction tube can be placed through the drainage channel, which is easy to detect when the location is incorrect. Therefore, its clinical application range is wider, in addition to the limbs and surface surgery, but also suitable for laparoscopic abdominal surgery.

Inflatable Laryngeal Mask model selection

Neonatal laryngeal mask size 1.0 (<4 kg)

Baby (5 ~ 10 kg) Laryngeal mask size 1.5

Laryngeal mask size 2.0 for children (10 ~ 20 kg)

Laryngeal mask Size 2.5 for children (20 ~ 30 kg)

Laryngeal mask 3.0 size for adult (30 ~ 50 kg)

Laryngeal mask size 4.0 for adults (50 ~ 70 kg)

Laryngeal mask size 5.0 for adults (70 to 100 kg)

Laryngeal mask size 6.0 for adult (>100 kg)

Inflatable Laryngeal Mask operation method

1.The recommended method is the supine position with the doctor standing on the patient's head. Tilt the patient's head back, fully deflate and shape the air bag, then insert the mask forward down the hard palate, and the right hand indicator can help push the tongue. A water-based lubricant is applied to the distal surface to reduce the resistance to insertion. Patients suspected of neck injury should not tilt their heads back

2.After inflating a small part of the laryngeal mask filling air bag, the mask can be inserted downward along the hard palate towards the head end. Once it reaches the throat, it can rotate 180°, push down and inflate when encountering resistance.

3.disposable laryngeal mask can be inserted without pumping air. After the laryngeal mask was placed, positive pressure ventilation was applied to observe the degree of chest fluctuation, whether the respiratory sounds on both sides of auscultation were symmetrical and clear, and whether there were air leakage noises in the anterior neck area.

4.The time to exit the laryngeal mask can be divided into deep anesthesia extubation and shallow anesthesia extubation. Deep anesthesia can avoid airway reflex and laryngeal spasm caused by irritation, but there may be aspiration and airway obstruction. Shallow anaesthetic extubation ensures recovery of protective reflex, but there is a risk of airway overreaction.

The advantages of Inflatable Laryngeal Mask

1.Easy to use, quickly establish artificial airway (autonomous, control).

2.High success rate of intubation, the first success rate of untrained 87%, two total success of 99.81%.

3.Reliable ventilation, replacing the mask effect is better.

4.Can avoid throat, vocal cords and trachea damage.

5.Little stimulation and little cardiovascular response.

6.First aid (emergency ventilation).

The disadvantages of Inflatable Laryngeal masks

1.The sealing effect is not good, can cause flatulence (especially IPPV), should not be too high positive pressure ventilation.

2.Laryngeal mask is more prone to esophageal reflux than mask, and should not be used in patients with full stomach.

3.Increased oral secretions.

4.Some types of laryngeal mask cannot use ordinary sputum suction tube to attract tracheal secretions through laryngeal mask.
