The treatment of bronchial asthma by dorsal sympathectomy; direct and indirect (use of alcohol) levin, g. l. l. ann. surg. 102 161, 1935 – que es la anoxia


Dyspnea and represents an equilibrium that functions to a degree 111

Dependently of the respiratory gaseous exc:hange.

Graphic records of the pulmonary ventilation in a patienx wita eon

Tinuous asthma receiving helium-oxygen mixttrres showed : (1) (lc-

Crease in pulmonary ventilation ; (2) decrease ill p~dmonaq~ jtmmire ;

(3) relative and absolute diminution in the length of the expiratiolr;

And (4) increased rest period between respiratory cycles.

Other types of cases of severe obstnrcti~~e dyspnea are mentioned

In which the helium was of benefit. Because of the marked anoxemia

In these eases a higher percentage of oxygen was needed.

An interesting experiment, is cited in t.!Ie case of a sixty-year-olti

que es la anoxia

Man with emphysema, chronic nephritis, myocardial fibrosis, paroxys-

Mal cardiac dyspnea, and cheyne-stokes breathing. Reliun-oxygeli

Mixture improved the condition somewhat, because of the lesser dif-

Ficulty in breathing and greater diffusion of the oxygen. TvhCll 1m

Per cent oxygen was inhaled, the breathing became entirely regular,

Demonstrating the chemical factor in the causation of this type of

Cardiac dyspnea.

In the technic of administration of helium-oxygen mixtures a nuns-

Ber of points are of importance. Helium is noninflammable and noit-

Toxic. It is very costly, however, and because of its very great dif-

Fusibility special precautions are taken against leaks a.Nd losses. The

Gas is usually administered with the oxygen through a special closed

Apparatus or by means of a tent. The concentration of helium rn~tst

Be watched. The concentration of oxygen must, be constantly watched,

Since there is real danger from asphyxia. IRally devices are suggested

To safeguard the deprivation of oxygen-a,ir ailalysis: emergency auto.

Matic tanks, and alarm signals.

Reatment of bronchial asthma by dorsal ym~at~ect~rny ;

And indirect (use of alcohol). Levin, 0. I,. IJ. : ann. Snrg. 102:

161, 1935.

There is sufficient pathologic and clinical evidence to shorn that I i!I:

Dorsal sympathetic nerves, especially the second to the sixth rami.

Contain both contractor and sensory fibers to the bronchial muscda-

Ture. The rami are accessible for neumtomy or for neurolysis by

Absolute alcohol, immediately below the points of junction with the

Intercostal nerves; the trunk can be reached above tae level of the

Ueek of the fourth rib. IIe reviews the other, methods of mgus ~IIIC!

Sympathetic operations and concludes that from the clinical a11ci wiâ-

Gical evidence the vagus is not the constrictor bro~;c:illal uer’ve.

The methods recommended are either the destruction of the rami by

Several injections of alcohol, 2.5 C.C. At a dose, or by a similar destruc-

Tion of the upper portion of the thoracic ganglionated trunk. Of 2:i


Patients with severe asthma treated by these methods complete relief

Was obtained in 75 per cent with varying degrees of improvement in

The remainder.Que es la anoxia perforation of the pleura took place in three patients

With no serious consequences.

Bronchial asthma due to paper sensitivity; case. Bennett, T. : new

England J. Ned. 213: 121, 1935.

In a ten-year-old girl who had asthma of six yearsâ duration it be-

Came apparent that the attacks followed shortly the ea.Ting of paper,

A habit which had persisted since infancy. The author obtained a

Marked reaction from a skin test with paper. Psychoanalytic treat-

Ment broke the child of the ha.Bit, and she has not had any asthma

For severa. Months.

Concurrence of diabetes mellitus and bronchial asthma. Kiinig, F. :

Ned. Klin. 31: 545, 1935.

Among 1,240 diabetic patients the author encountered only three

Instances of asthma.Que es la anoxia he cites other reports which indicate that among

Asthmatic persons there are few diabetics (6 in 4,000). The explana-

Tion offered for the rarity of association between these two diseases

Is that there is an antagonism existing between insulin and adrenalin.

The diagnostic and therapeutic use of iodized oil in cases of in-

Tractable asthma. Balyeat, A., seyler, L. E., and shoemaker, H. A. :

Radiology 24: 303, 1935.

The authors believe that most cases of asthma have a dual eanse, a

Specific factor and a mechanical factor-the latter produced by tena-

Cious or purulent mucus. They say that attention should also be given

To the mechanical causes. Iodized oil intratracheally is described as

An ideal means of treating the latter.Que es la anoxia from 5 C.C. To 10 C.C. Of the oil

Is instilled at weekly, biweekly, or monthly intervals. Of 50 patients

With asthma in whom poor results were obtained by allergic manage-

Ment, good results were finally obtained in 35 by the addition of the

Iodized oil treatment.

Ionized air in bronchial asthma. ~iandsman, I. E. : sovet. Vrach. Gaz.,

Pp. 227-232 (feb. 15), 1935.

The author calls attention to the literature dealing with effects of

Weather on the 1luma.N and animal organism. He thinks that the dc-

Gree and polarity of ionization is the determining factor in this effect.

He believes also that that constitutes the probable reason why asth-

Matic patients are often relieved by a change of climate.
