Dr. J. J. Ridge says in Addresses on the Physiological Action of Alcohol:—
“It has been found by experiment that, when alcohol is taken, less carbonic acid comes away in the breath than when it is not. This is partly because the blood-corpuscles cannot carry so much, and partly because so much is not produced, because there is less oxygen to join with the food and produce it. Just as burning paper smokes when it does not get enough oxygen, so other things are formed and get into the blood when there is not enough oxygen to make carbonic acid. These things make the blood impure, and cause extra work and trouble to get rid of them. This is why persons who drink alcohol are more liable to have gout and other diseases, than total abstainers.”
Dr. Alfred Carpenter, formerly president of the Council of the British Medical Association, says in Alcoholic Drinks:—
“A blood corpuscle cannot come into direct contact with an atom of alcohol, without the function of the former being spoiled, and not only is it spoiled, but the effete matter which it has within its capsule cannot be exchanged for the necessary oxygen. The breath of the drunken man does not give out the quantity of carbonic acid which that of the healthy man does, and the ammoniacal compounds are in a great measure absent. Some of the carbon and effete nitrogenous matter is kept back. The retention of these poisonous matters within the body is highly injurious. Let the drinker suffer from any wound or injury and this effete matter in his blood is ready at a moment’s notice to prepare and set up actions called inflammatory or erysipelatous, or some other kind; by means of which too often the drinker is hurried into eternity, although, perhaps, he may have been regarded as a perfectly sober man, and have never been drunk in his life.”
In the light of these scientific facts, what can appear more utterly foolish than the swallowing of alcoholic patent medicines which are widely advertised as “Blood Purifiers”? That they will render the blood impure is only too evident in the light of scientific truth.
Dr. Nathan S. Davis has written much in disapproval of the use of alcohol in fevers, pneumonia and diphtheria, putting stress upon the fact that these diseases, of themselves, interfere with the reception of oxygen into the blood, and hence the use of all remedies that notably diminish the internal distribution of oxygen, or impair the corpuscles of the blood, should be avoided. Not only is alcohol of such a nature, but all the coal-tar series of antipyretics also. Since the internal distribution of oxygen, and the processes of tissue change are essential to the repair of the body, and alcohol hinders the blood in the full performance of its duties in these respects, it certainly seems clear that those physicians, who are extremely cautious in the use of this drug, or who do not use it at all, are more likely to be successful in saving their patients than are those who use it freely. Death-rates, with and without alcohol, show conclusively the superiority of the latter treatment.
ALCOHOL AND THE HEART.The organs of circulation are the heart and the blood-vessels. The blood-vessels are of three kinds, arteries, capillaries and veins. The arteries carry blood from the heart to the capillaries; the veins collect it from the capillaries and return it to the heart. There are two distinct sets of blood-vessels in the body, both connected with the heart; one set carries blood to, through and from the lungs, the other guides its flow through all the remaining organs; the former are known as the pulmonary, the latter as the systemic blood-vessels.
The smallest arteries pass into the capillaries, which have very thin walls, and form very close networks in nearly all parts of the body; their immense number compensating for their small size. It is while flowing in these delicate tubes that the blood does its nutritive work, the arteries being merely supply-tubes for the capillaries, through whose delicate walls liquid containing nourishment exudes from the blood to bathe the various tissues.
The quantity of blood in any part of the body at any given time is dependent upon certain relations which exist between the blood-vessels and the nervous system. The walls of the arteries are abundantly supplied with involuntary muscular fibres, which have the power of contraction and relaxation. This power of contraction and relaxation is controlled by certain nerves called vasomotor nerves, because they cause or control motion in the vessels to which they are attached. When arteries supplying blood to any particular part of the body contract, the supply of blood to that part will be diminished in proportion to the amount of contraction. If the nervous control be altogether withdrawn, the arterial walls will completely relax, and the amount of blood in the part affected will be increased correspondingly.
Alcohol, even in moderate doses, paralyzes the vasomotor nerves which control the minute blood-vessels, thus allowing these vessels to become dilated with the flowing blood.
“With the disturbance of power in the extreme vessels, more disturbance is set up in other organs, and the first organ that shares in it is the heart. With each beat of the heart a certain degree of resistance is offered by the vessels when their nervous supply is perfect, and the stroke of the heart is moderate in respect both to tension and to time. But when the vessels are rendered relaxed, the resistance is removed, the heart begins to run quicker like a clock from which the pendulum has been removed, and the heart-stroke is greatly increased in frequency. It is easy to account in this manner for the quickened heart and pulse which accompany the first stage of deranged action from alcohol.”—Richardson.
Dr. Parkes of England, assisted by Count Wollowicz, conducted inquiries upon the effects of alcohol upon the heart, with a young and healthy man. At first they made accurate count of the heart beats during periods when the young man drank water only; then of the beats during successive periods in which alcohol was taken in increasing quantities. Thus step by step they measured the precise action of alcohol on the heart, and thereby the precise primary influence induced by alcohol. Their results are stated by themselves as follows:—
“The average number of beats of the heart in 24 hours (as calculated from eight observations made in 14 hours), during the first, or water period, was 106,000; in the earlier alcoholic period it was 127,000, or about 21,000 more; and in the later period it was 131,000, or 25,000 more.
“The highest of the daily means of the pulse observed during the first, or water period, was 77.5; but on this day two observations are deficient. The next highest daily mean was 77 beats.
“If, instead of the mean of the eight days, or 73.57, we compare the mean of this one day; viz. 77 beats per minute, with the alcoholic days, so as to be sure not to over-estimate the action of the alcohol, we find:—
“On the 9th day, with one fluid ounce of alcohol, the heart beat 4,300 times more.
On the 10th day, with two fluid ounces, 8,172 times more.
On the 11th day, with four fluid ounces, 12,960 times more.
On the 12th day, with six fluid ounces, 20,672 times more.
On the 13th day, with eight fluid ounces, 23,904 times more.
On the 14th day, with eight fluid ounces, 25,488 times more.
But as there was ephemeral fever on the 12th day, it is right to make a deduction, and to estimate the number of beats in that day as midway between the 11th and 13th days, or 18,432. Adopting this, the mean daily excess of beats during the alcoholic days was 14,492, or an increase of rather more than 13 per cent.
The first day of alcohol gave an excess of 4 per cent., and the last of 23 per cent.; and the mean of these two gives almost the same percentage of excess as the mean of the six days.
Admitting that each beat of the heart was as strong during the alcoholic period as in the water period (and it was really more powerful), the heart on the last two days of alcohol was doing one-fifth more work.
“Adopting the lowest estimate which has been given of the daily work of the heart; viz. as equal to 12.2 tons lifted one foot, the heart during the alcoholic period, did daily work excess equal to lifting 15.8 tons one foot, and in the last two days did extra work to the amount of 24 tons lifted as far.
“The period of rest for the heart was shortened, though, perhaps, not to such an extent as would be inferred from the number of beats, for each contraction was sooner over. The heart, on the fifth and sixth days after alcohol was left off, and, apparently at the time when the last traces of alcohol were eliminated, showed in the sphygmographic tracing signs of unusual feebleness; and, perhaps, in consequence of this, when the brandy quickened the heart again, the tracings showed a more rapid contraction of the ventricles, but less power than in the alcoholic period. The brandy acted, in fact, on a heart whose nutrition had not been perfectly restored.”
Richardson quotes these experiments of Parkes and Wollowicz as if he agrees with them that increased heart-beat must of necessity mean increased work done by the heart. Dr. Nathan S. Davis, Dr. Newell Martin, Dr. A. B. Palmer, and some other investigators, show conclusively that mere increased frequency of beat above the natural standard is no evidence of increased force or efficiency in the circulation.
“The more frequent beats under the influence of alcohol constitute no exception to the general rule, for while the heart beats more frequently, its influence on the vasomotor nerves causes dilatation of the peripheral and systemic blood-vessels, as proved by the pulse-line written by the sphygmograph, which more than counterbalances the supposed increased action of the heart. The truth is, that under the influence of alcohol in the blood the systolic action of the heart loses in sustained force in direct proportion to its increase in frequency, until, by simply increasing the proportion of alcohol, the heart stops in diastole, as perfectly paralyzed as are the coats of the smaller vessels throughout the system. This was clearly demonstrated by the experiments of Professor Martin of Johns Hopkins University, to determine the effects of different proportions of alcohol on the action of the heart of the dog; and those of Drs. Sidney Ringer and H. Sainsbury, to determine the relative strength of different alcohols as indicated by their influence on the heart of the frog. Professor Martin states that blood containing ¼ per cent. by volume of absolute alcohol, almost invariably diminishes, within a minute, the work done by the heart.”
(This estimate would equal in an adult man an amount equal to the absolute alcohol in two or three ounces of whisky or brandy.)
“These investigations of Professor Martin, being directly corroborated by those of Drs. Ringer and Sainsbury, complete the series of demonstrations needed to show the actual effects of alcohol on the cardiac, as well as on the vasomotor, and also on the direct contractability of the muscular structure, when supplied with blood containing all gradations in the relative proportion of alcohol, leaving no longer any basis for the idea, popular both in and out of the profession, that alcohol in any of its forms is capable of increasing, even temporarily the force or efficiency of the heart’s action.”—Dr. N. S. Davis in Influence of Alcohol On the Human System.
