The experience of Xiaowu learning laryngeal mask (1) Recently, I was very fortunate to participate in the online class of the panoramic airway laryngeal mask training class and learn with all the airway management experts.
The teachers are very serious and responsible, and I have learned a lot.
The laryngeal mask is really not It is a pity tool that is tasteless and discarded.
If the laryngeal mask is used well, it can really solve many difficult clinical problems.
OK, let everyone follow my learning step by step to uncover the mystery of the laryngeal mask.
What is the status of the laryngeal mask? What? The first thing to know is that it is a supraglottic airway device
.
A supraglottic airway (SGA) device is a type of airway device that can be inserted into the pharynx for ventilation, oxygen supply, and anesthetic gas administration without the need for endotracheal intubation
.
For anesthesia, these devices can be used for initial airway management, for rescue ventilation when mask ventilation is difficult, and as a channel for endotracheal intubation

OK From this sentence we can know that the supraglottic airway serves at least three purposes 1.
As a tool for initial airway management 2.
Useful when mask ventilation is difficult For rescue ventilation 3.
The most commonly used SGA in the operating room is the laryngeal mask airway (LMA)
.
The LMA consists of a mask-like cuff and a hollow rod or catheter connected to it.
The cuff is placed in the hypopharynx, facing the glottis, and its tip is located at the entrance to the esophagus
.
Having said so much, we have a tracheal tube, the location is reliable, and the ventilation is reliable.
Is it necessary to learn the laryngeal mask? 1.
In the case of difficult airway, it may save lives when the tube cannot be inserted.
This is the reason why he is included in the difficult airway treatment process.
It is also here to remind everyone that in an emergency where neither intubation nor mask ventilation is possible Consider the laryngeal mask first! 2.
The comparison on the prepared items is clear at a glance.
I have a very deep image of the picture below.
I will not go into details about the advantages of the laryngeal mask.
First, the learning curve is very short.
Second, the stimulation of insertion is far less than that of intubation.
The hemodynamics are stable and the patient is well tolerated.
, the sore throat is also much less.
There are detailed comparisons in the fifth edition of Morgan Anesthesia.
Many big coffees have inserted a laryngeal mask for themselves.
Dr.
Joseph Brimacombe, the author of "Principle and Practice of Laryngeal Mask Anesthesia", personally tested the comfort and airtightness of ProSeal-LMA.
.
What is the history of the invention of the laryngeal mask? Many public accounts have a lot of explanations about the history of its invention.
Archie Brain Its inventor has made great contributions to the development and progress of the laryngeal mask.
The first laryngeal mask in history is still displayed in the British Medical Museum in 1981.
Dr.
Archie Brain invented the first laryngeal mask, which he used to anesthetize patients, and submitted, rejected, rejected, rejected, and finally published in BJA in 1983
.
The manual laryngeal mask is too labor-intensive, and the quality and feel are not very good, so he thought of finding a company to invest in this way
.
However, the investment road of laryngeal mask has also failed many times.
In 1986, I found Dunlop Company (that is, the famous company that produces tires) and wanted to use silicone to make laryngeal masks, but the company expressed no interest, and no one was willing to invest in mass production
.
In 1987, with Cooper's support, Bivona in India offered to manufacture laryngeal masks in bulk
.
On December 5, 1987, Dr.
Brain saw the first commercialized laryngeal mask product, the LMA Classic™
.
This silicone-cuffed laryngeal mask has also made LMA a world-renowned brand in the field of anesthesia
.
In 1988, the laryngeal mask was launched in the UK, initially by a company that made pacifiers
.
Under the promotion of Nunn, a famous British anesthesiologist, a clinical experiment was carried out, in which 18 anesthesiologists who had never used a laryngeal mask used the No.
3 laryngeal mask on 100 patients, and achieved a 98% success rate.
The results were published in Anaetheisa, highlighting the advantages of the laryngeal mask, which has been widely used since then
.
During clinical application, Dr.
Brian found that the laryngeal mask ventilation tube was twisted in individual cases, so the flexible laryngeal mask came into being (1989, Flexible LMA).
The flexible laryngeal mask is especially suitable for head and neck, oral cavity, ENT department Such as surgical cases that are prone to cause airway distortion during surgery
.
In 1990 - the laryngeal mask was introduced into China for use.
In 1991 - the FDA approved the use of the laryngeal mask in the clinic
.
Subsequently, in order to solve the tracheal intubation of patients with difficult airway 1993 - laryngeal mask was used as one of the tools for difficult airway treatment by ASA 1997 - Dr.
Using intubated laryngeal mask (LMA Fastrac), double tube laryngeal mask (supreme LMA, ProSeal-LMA) 1999 - 100 million patients worldwide have successfully received laryngeal mask anesthesia, Dr.
Brian's persistent innovations are like An industrial revolution that promoted the advancement and development of anesthesiology 2003 - Dr.
Muhammed Aslam Nasir from Pakistan invented a cuffless laryngeal mask - i-gel laryngeal mask 2004 - In order to improve the intubated laryngeal mask Due to the defects of arytenoid cartilage injury, mistaken entry into the esophagus, and the need for fiberoptic bronchoscopy guidance, the visual intubation laryngeal mask (LMA CTrach) was invented and popularized
.
2007 - Brain won the Future of Medicine Innovation Award, Lifetime Achievement Award for inventing the laryngeal mask
.
2013 - The ASA Difficult Airway Guidelines have listed the laryngeal mask as an important tool for managing difficult airways
.
This picture simply reflects the development process of the laryngeal mask.
