From all that has been said, there ought seldom to be much difficulty in recognizing a case of poisoning with spirituous liquors.
But, before quitting the subject, a form of it must be noticed which may be extremely difficult to distinguish. It was formerly remarked that the eatable mushrooms have been sometimes poisoned with substances possessing effects on the system analogous to those caused by the deleterious fungi. In the same manner spirituous liquors may be poisoned with narcotics allied to them in action. Thus, in former parts of this work, it has been stated that a young man was killed during a debauch in consequence of his companions having mingled opium with his wine; that many persons have been poisoned and some killed by fermented liquors drugged in the same manner; that murder has been accomplished by poisoning wine with nightshade; and that several fatal accidents have occurred in consequence of liqueurs having been too strongly impregnated with hydrocyanic acid, to give them a ratafia flavour. Cases of this nature may be embarrassing. In general, they may be made out by attending strictly to the symptoms, the quantity of liquor taken, and the contents of the stomach. But, it must be admitted, that if a murderer, who chooses such a method, should season his guest’s drink judiciously, and ply him well with it, a medical jurist might be puzzled to determine whether the liquor was to blame in point of quality or quantity.
Of the Treatment.—The treatment of poisoning with alcoholic fluids does not differ essentially from that of poisoning with opium. In the former, as in the latter, the chief objects must be to remove the poison from the stomach, and to rouse the patient from his state of stupor; but in poisoning with alcoholic fluids it is also frequently necessary to treat a secondary stage of reaction by local and even general antiphlogistic measures. As to the primary object, the removal of the poison from the stomach, it appears that in the present form of poisoning emetics are more seldom effectual than in the case of other narcotics, and that the stomach-pump should be promptly resorted to. It is remarkable that the operation of clearing out the stomach is likewise often a sufficient stimulus to dispel stupor immediately and even permanently. I have seen almost complete consciousness permanently restored with the discharge of the alcoholic fluid; and the same remark has been made by others. Where the senses are not thus restored, one of the most effectual stimulants, according to the practice of the police-office of this city, is the injection of water into the ears. Great advantage has been derived, as in poisoning with opium, from the cold affusion applied to the head. Dr. Ogston, who has appended to his paper formerly quoted a very useful summary of the treatment of poisoning with spirits, has found this a safe and effectual remedy where the heat of the head was unnaturally great and that of the body not too low.[[2539]] Cases have been published where it proved successful although the pulse was gone at the wrist, the breathing scarcely perceptible, and the temperature of the whole body greatly reduced.[[2540]] It is doubtless a powerful remedy: but where the general temperature of the surface is much lowered, I conceive it should be restricted to the head and neck, and conjoined with the application of warmth to the body. Dr. Ogston objects to the general use of blood-letting in cases of poisoning with spirits, as being often apt to be followed by sudden sinking. Where other remedies are judiciously used, it is probably seldom called for; and the purpose it is intended to serve, namely, the relief of cerebral congestion and determination, is better fulfilled by the local employment of cold, and local blood-letting. Ammonia and its acetate have been found useful as internal stimulants where the stupor is deep. The treatment of the secondary affections adverted to above does not require specific mention.
Of Poisoning with Sulphuric and Nitric Ether.
Sulphuric ether and nitric ether are poisons of the same nature with alcohol. But the effects produced by them when taken in considerable doses are not very well known.
Orfila found that half an ounce of sulphuric ether introduced into the stomach of a dog and secured there by a ligature on the gullet, excited efforts to vomit, in ten minutes inability to stand, and in six minutes more, insensibility. In fifteen minutes more the animal revived a little, but soon became again comatose; and it died in three hours after the commencement of the experiment. The villous coat of the stomach was reddish-black, the other coats of a lively red colour.[[2541]]
The effects of the ethers on man have not been accurately ascertained. From some observations published in the Journal of Science, sulphuric ether appears to act energetically even in small doses. In moderate quantity it produces a strong sense of irritation in the throat, a feeling of fulness in the head, and other symptoms like those excited by nitrous-oxide gas. A gentleman, in consequence of inhaling it too long, was attacked with intermitting lethargy for thirty-six hours, depression of spirits and lowness of pulse.[[2542]] When long and habitually used, as by persons afflicted with asthma, its dose must be gradually increased; and it appears that considerable quantities may then be taken for a great length of time without material injury. I have been informed of an instance of an asthmatic gentleman about sixty years of age who consumed sixteen ounces every eight or ten days, and had been in the habit of doing so for many years. Yet, with the exception of his asthma, he enjoyed tolerable health.
An interesting case has been published which proves that nitric ether in vapour is a dangerous poison when too freely and too long inhaled. A druggist’s maid-servant was found one morning dead in bed, and death had evidently arisen from the air of her apartment having been accidentally loaded with vapour of nitric ether, from the breaking of a three-gallon jar of the spiritus etheris nitrici. She was found lying on her side, with her arms folded across the chest, the countenance and posture composed, and the whole appearance like a person in deep sleep. The stomach was red internally, and the lungs were gorged.[[2543]] The editor of the journal, where this case is related, says he is acquainted with a similar instance where a young man became completely insensible from breathing air loaded with sulphuric ether, remained apoplectic for some hours, and would undoubtedly have perished had he not been discovered and removed in time.
Of Poisoning with the Oleaginous products of Combustion.
The physiological effects of these substances have not yet been extensively investigated. It has been already mentioned, that the empyreumatic oils of tobacco and other narcotic vegetables are active poisons; and that the emanations from candle snuffings and imperfectly consumed tallow probably owe their injurious properties to a peculiar oil. Many empyreumatic oils are known, and some are used in medicine, which act powerfully on the animal system as stimulants and antispasmodics. Among these may be enumerated naphtha, oil of galbanum, oil of guiaiac, oil of amber, oil of wax, and Dippel’s oil. The last in particular, which is the rectified empyreumatic oil of hartshorn, but is prepared also from blood and various animal matters,[[2544]] has been a good deal used of late on the continent for medical purposes, and has even been resorted to as a poison for the purpose of self-destruction.
