My second visit was at 12 M., one hour and a half later than the first. Patient was found in a deep stupor; surface cold; extremities and face shrunken and blue; pulse barely perceptible; large liquid and offensive stools occasionally escaped from the bowels without the consciousness of the patient. Death at 3 o'clock P.M.
Miss H., living in a malarious situation, complained about noon of September 19th of great cerebral fulness and unaccountable sleepiness and debility. She retired to her room, and after a few hours' sleep resumed her household occupations. On the 20th similar symptoms manifested themselves, but earlier in the day. She again slept for some hours, but complained of great prostration after the sleep. On the 21st, about 10 A.M., she complained of a return of the stupor, and while retiring to her room requested that I should be called if she did not awake in a better condition. At 1 P.M. she was found profoundly comatose, with cold extremities and surface and bathed in perspiration. When I reached her residence at 3 P.M. she had expired.
There is a common belief among non-professional people that the third congestive chill is necessarily fatal. There is no foundation for this opinion, except in the fact that when congestive chills are waxing in their perniciousness the subject is seldom able to survive the third recurrence if the second or first should not prove fatal.
It is difficult to account for the pathological dissimilarity between the simple and congestive types of malarial fevers. If we say that congestive chills are produced by an intensification of those causes which produce and govern an ordinary chill, we make an explanation which, however unsatisfactory, represents very nearly the full extent of our knowledge on this point.
It cannot be admitted that alterations of quantity or quality of the malarial poison exercise the sole influence in determining the occurrence of congestive cases. All experienced practitioners understand that certain constitutional conditions may pervert simple chills into congestive forms by producing prolongation or aggravation of the states of congestion always present in ordinary chills. Weakened cardiac function, from whatever cause, may be reckoned among these conditions. In these cases the feeble vis a tergo yields readily to those perturbations of vaso-motor influence which occasion passive blood-accumulations in the small veins and capillaries. I may say further, in speaking of the influence of the vaso-motor nerves in governing the phenomena of a chill, that we know that in congestive chills the cerebro-spinal system is much less the seat of symptomatic phenomena than in simple attacks. On the other hand, the organic system is far more profoundly affected.
However we may account for the perversions of normal circulation underlying and producing congestive chills, the great degree of injury they are liable to inflict is so well understood as to awaken the most serious apprehensions whenever we are called upon to treat them. Congestion, however occasioned, may destroy life through abolishment of function by the sheer physical change of infarction, or, again, through those inevitable consequences which arrested circulation entails upon the blood. Blood-stasis is followed by separation of its constituents, and its disqualification as a circulatory fluid in a degree proportionate to the duration of the stoppage, and probably also to the actual extent of the passive engorgement. Thence result the formation of coagula in the congested vessels and deposits of pigmentary matter. If partial reaction should occur, portions of this blood-débris may be floated to various parts of the circulatory system, and give rise to greater or less important alterations of function.
Among the white soldiers of the United States army from May 1, 1861, to June 20, 1866, 13,673 cases were diagnosed as congestive intermittent fever. Of this number, 3370 died, being a mortality-rate of 23.91 per cent. The aggregate number of malarial cases returned was 1,255,623. It would therefore appear that 1 case in not quite 372 was congestive in its type, or 1.08 per cent. The late Dr. Cook of Washington, La., estimated 2 per cent. of his malarial cases to be of the congestive type. It can scarcely be doubted that the ratio of congestive attacks is greater in the more southern belts of latitude than in the middle or northern parts of the United States. Chronic malarial toxæmia and the enervating effects of long-continued heat upon the circulation must occasion an increased proportion of such attacks, but my own observations show slightly more than 1 per cent. of the cases treated in the Charity Hospital to have been of the congestive form.
The cure of a congestive chill is one of the most difficult problems the physician can possibly encounter. It is nothing less than the proposition to remove a perverted state of the blood-vessels which is dependent upon some influence exerted through a nervous apparatus whose therapeutics and experimental physiology are imperfectly understood. While a satisfactory solution of this problem will probably be a remote achievement in medicine, it was long ago empirically ascertained that certain agents exercised some degree of control over the cold stage of febrile attacks. For the most part, these agents are addressed to those perversions of nerve-function which constitute so important a part of the pathology of a chill. They are identically the same remedies whose aid we invoke to allay many other forms of perturbed nervous action. Opium, chloroform, belladonna, chloral hydrate, and bromide of potassium have proved more or less valuable, according to the idiosyncrasy of the patient or the circumstances under which they have been used. I consider opium the most valuable of these remedies. It should be given in moderate doses, and preferably combined with chloroform or ammonia, or, if more expedient to administer per rectum, combined with solutions of chloral hydrate or bromide of potassium. One-sixth of a grain of morphia, combined with one-fortieth or one-fiftieth of a grain of atropia, is an available and useful prescription when given hypodermically. Rubbing the extremities or the spine, or indeed the whole surface, with ice, is a mode of practice well worthy of attention. In the event of inability to procure ice, douches of cold water, followed by frictions with coarse towels, may be substituted. I have used nitrite of amyl by inhalation, but its effects are too transitory to prove serviceable.
Some practitioners speak highly of alcoholic stimulants. My own experience has not been favorable to their use. Perhaps their benefits are altogether restricted to those cases in which previously weakened heart-function existed. But it is important that alcohol be added in all those cases of pernicious malarial fever, whatever the type may be, where cardiac stimulation and improvement of nutrition are leading indications.
I am sure I have often derived benefit from enemas consisting of four ounces of well-prepared beef essence with a half ounce of whiskey or brandy and a half ounce of strong infusion of coffee.
