Staines detailed Dick's case in a remarkable paper, entitled "Oedema of the Glottis," and showed how the patient had been brought back from the grave by tracheotomy and artificial respiration. He received a high price for this article. To tell the truth, he was careful not to admit that it was he who had opened the windpipe; so the credit of the whole operation was given to Mr.
For instance, if it is necessary that the glottis be contracted to a point which we will call "half-open" for the production of a certain sound, the brain must first send a message to that organ before the necessary movement can take place. In saying the word "you," for instance, it would be necessary for the tongue to press tip against the base of the lower row of front teeth.
The mechanism of this rare and fatal form of injury has been very aptly described by Gosselin as due to a sudden pressure exerted on the thoracic wall at the moment of full inspiration, there being a spasm of the glottis or obstruction of the larynx, in consequence of which the lung bursts. An extravasation of air occurs, resulting in the development of emphysema, pneumothorax, etc.
The vibration is small in amount, but very rapid. Other muscles are connected with the arytenoid cartilages which serve to seperate the vocal cords and to widely open the glottis. The force of the outgoing current of air determines the extent of the movement of the cords, and thus the loudness of the sound will increase with greater force of expiration.
In these children every burst of crying, however produced, whether by a fall, by a fright, by the entrance of a stranger, or by a visit to a doctor, is apt to be ushered in by a long period of apnoea, due to spasm of the glottis and of the diaphragm. The first few expirations are not followed by any inspiration.
Not only is the voice-emission pure, but there is no needless fatigue of voice, because all superfluous movement of the glottis is avoided. The "check glottid" or glottic shock, on the other hand, involves an undue effort of the vocal muscles, and the compression of the vocal cords causes irritation.
She suffered she told me it was a Moultrie castemark from some obscure form of chronic bronchitis, complicated with spasm of the glottis; and, in a dead, flat voice, with a sunken eye that looked and saw not, told me what washes, gargles, pastilles, and inhalations she had proved most beneficial.
For all changes and variations of state in organic substances are such that once they are habitual they become permanent. So the lungs are habituated to produce certain sounds in the trachea, to vary them in the glottis, articulate them by the tongue, and modify them by the mouth; once these organic activities have become habitual, they are settled in the organs and can be reproduced.
We can thus, as I infer from Professor Owen's interesting description of these parts, understand the strange fact that every particle of food and drink which we swallow has to pass over the orifice of the trachea, with some risk of falling into the lungs, notwithstanding the beautiful contrivance by which the glottis is closed.
This thoroughly empties and cleanses the stomach. From a pint to a quart is usually sufficient, although two quarts will do no harm. If the stomach does not reject it readily, thrust the forefinger down the throat to the end of the glottis. The third method is by the stomach tube.
