OF THE Autumnal Remitting Fever.
Reading edition
The Remitting Autumnal Fever, called by the Antients συνεχης, was also one of the most frequent Disorders during the Campaign.
This Fever is observed in most Countries, after the Juices have been highly exalted by the Heat of Summer; and People are exposed to the Heats of Mid-Day, and to the cold Damps of the Night. We observe it every Year in the Neighbourhood of London, especially among the labouring People, who work in the Fields, towards the End of Summer, and in Autumn; but it is generally in a milder Degree than in Armies, where Men are more exposed to the Vicissitudes of the Weather.
As we go further towards the South, this, as well as other bilious Disorders, becomes more frequent.
This Fever is reckoned the endemic Distemper of the West Indies, of the Coast of Guinea, and other Places in the Torrid Zone; but in those warm Countries it appears in a more violent Degree; makes a much more rapid Progress; and proves far more fatal than in our cooler and more temperate Climate. And it is observed to be always most frequent and most fatal where a Country is covered with Wood, or is marshy; and where there are frequent Fogs, and much stagnating Water, which corrupts by the Heat of Summer.
In January, February, and March 1761, we had none of those Remitting Fevers at Paderborn. In April, some few of the Soldiers, on their Return from the Winter-Expedition into Hesse-Cassel, had Fevers attended with bilious Symptoms; but they were rather of the continued, inflammatory Kind, and tending to malignant, than such as could be called remitting.
The first Time that I saw much of this Fever, was among the Sick sent to Bilifield in the End of June 1761; soon after the Army took the Field. The Remissions were short, and it partook much of the Nature of the common Inflammatory Fever; and most of them were cured by the antiphlogistic Method. A Day or two before we left this Place, it began to change into the Malignant Hospital Fever, from the Sick being too much crowded.
In the Middle of July, about Twelve Hundred Sick were sent to the Hospital at Munster; and about one-third Part were ill of this Remitting Fever. It did not partake near so much of the inflammatory Nature as at Bilifield; the Remissions became much more evident; and it was attended much oftener in the Beginning with bilious Vomiting and Purging; and in some few the Disorder turned to a Dysentery. About eight or nine had it changed into the Hospital Fever, from the Wards in one of the Hospitals being too much crowded; and in some few the Disorder terminated in regular Agues. In November severals were taken ill of it in the Garrison of Bremen, which mostly ended in a regular Intermittent, the endemic Distemper of the Place. Towards the End of December we had none of these Remitting Fevers, the Disorders turning more to the inflammatory Kind.
In June 1762, this Fever began to appear again among the Sick, sent from the Army, to the Hospital at Natzungen; and it continued to be frequent through the Summer and Autumn; and the greatest Part of these Fevers this Year terminated in regular Agues, mostly in Tertians, and were cured by the Bark; whereas the Year before very few terminated this Way.
This Disorder in the Beginning had commonly the Appearance of a continued Fever; and many had a Sickness and Vomiting, and threw up a Quantity of yellow Bile, mixed with the Contents of the Stomach. In a few Days, especially after Bleeding, the Remissions became clear; tho’ on its first Appearance in June 1761 they were short, and rather obscure; and it seemed still to partake a good deal of the Nature of the common Inflammatory Fever, the Blood being very sizy; but as the Season advanced, the Remissions became more evident, and the Paroxysms more like those of an Ague; and the Blood less sizy, tho’ at all Seasons of the Year it had some Appearance of an inflammatory Buff in this Disorder. The Sick were restless and uneasy at Night; but commonly felt themselves cooler and lighter in the Day-Time: and although they had no cold Fit, as the Fever came on at Nights, and many of them no Breathing Sweat, as they became cooler and freer from the Fever in the Morning; yet the Fits were so remarkable, that many of the Patients used to say they had a regular Fit of an Ague every Night, or towards the Morning; and some few, that they had the Fit every second Night. As the Season advanced, the Remissions appeared more distinct. However, there was always a good Number in whom the Fever went on in a continued Form, through its whole Course, without any Signs of Remission; tho’ they had all the other Symptoms of this Fever. In a few Instances the Fever, after it came to remit, changed again into a continued Form.
The Heat in the Time of the Paroxysms rose high, and several were delirious during its Continuance[70]; but were quite sensible in the Intervals, though never wholly without the Fever.
At the End of July 1761, four or five were attacked with a Bleeding at the Nose, in the Time of the Paroxysms, and became cooler afterwards; but it did not prove a Crisis in any of them.
The Urine in the Beginning was commonly of a high Colour, though sometimes it was pale and limpid: At first it deposited no Sediment; but when the Fever came to remit, there was often a small Sediment after each Paroxysm; and as the Fever was going off, it let fall a Sediment in all[71].
Some at first were inclined to be costive; others had a Sickness and Purging; and several of those who were costive in the Beginning, were in the Course of the Disorder attacked with a Purging; and others, after some previous Complaint of the Stomach, were seized with both Vomiting and Purging. In general, after the Sick continued some Days in the Hospital, they were inclined to be loose; which was a favourable Circumstance, when this Evacuation was not so great as to be in Danger of sinking the Patient. Some were attacked with a Dysentery.
In this, as well as in most other Fevers, the Sick frequently passed by Stool Worms of the round Kind; and sometimes they vomited them up, or the Worms came up into their Mouth or Nostrils while they lay asleep in Bed; and some towards the Height were afflicted with Deafness, which was commonly a favourable Symptom.
Most of those ill of this Disorder had a yellowish Colour of the Countenance, which went off with the Fever. It was more observable in some than in others; in general, it was slight; some few became yellow all over[72]; particularly one Man, in the Hospital at Munster, who, after being seized with violent Vomiting and Purging, Convulsions, and Twitchings of the Tendons, and Hiccup, became yellow, as in the deepest Jaundice. This Symptom of Yellowness arises from a Redundancy and Absorption of Bile; and is sometimes observed in other Fevers as well as this[73]; for while we were at Paderborn in February 1761, two Men were brought to the Hospital in Fevers, attended with this Symptom. They were both delirious, with parched dry Tongues, slight Twitchings of the Tendons, and other bad Symptoms; and one of them had a continual Vomiting and Purging. They both died, and the Body of him who had the Purging was opened. All the Bowels, especially the Colon, were tinged with a yellow Bile, and had a slight Degree of Inflammation all over their Surface; the Gall-Bladder was distended with a very dark-coloured Bile; but no Concretions were found in its Cavity, or in the bilious Ducts; nor Mucus, or any other Thing obstructing these Passages. The Surface of the Lungs seemed slightly inflamed; and there was a small Quantity of greenish Serum in the Cavities of the Thorax. I could not learn the Histories of these two Mens Disorders, before they were brought to the Hospital; but, from the Symptoms, was inclined to believe, that the Fevers had been of the malignant or petechial Kind; and that the yellow Colour was only an accidental Symptom of it; for on one of the Men we could perceive obscure Traces of dun petechial Spots on his Breast and Arms; and the malignant Fever was frequent at this Time among the Troops, and the bilious autumnal Fevers had ceased long before.
I could not observe any certain critical Days, or Periods, when this Disorder terminated.—Some, who had it slightly, got well in a few Days; with others, it continued longer: Some continued long feverish, and would seem cooler and freer from Fever for a Day or two, and then grow worse again; and many had repeated Relapses.
Neither could I observe any regular Crisis in this Fever. Sweat was the Discharge which oftenest proved critical. Many seemed to be relieved by a Purging; but as the greater Part had a Looseness after some Days, which continued often through the Disorder, without producing any very sudden Change in the Symptoms, it seemed to be a favourable Circumstance; though it seldom carried off the Fever so suddenly as to be manifestly critical. The Urine broke, and dropt a Sediment, for the most part, as the Fever took a favourable Turn.
When this Fever proved mortal, it commonly assumed a continued Form; the Tongue became parched and dry, the Patient delirious, with Twitchings of the Tendons, Hiccup, and other fatal Presages; while others were seized with a violent Diarrhœa, or Dysentery, which sunk them irrecoverably.
In the Beginning, it was absolutely necessary to bleed the Patients freely; and frequently to repeat the Evacuation, where the Symptoms required it. The Blood was of a florid Colour, and commonly threw up more or less of an inflammatory Buff.
In these Fevers, we were obliged to have particular Regard to the first Passages, especially in the Beginning of the Disorder; for they were generally loaded with bilious Humours[74]; which, if suffered to remain in the Bowels; were either absorbed, and increased the Heat and Fever, or brought on a violent Diarrhœa; and therefore, after Bleeding, we gave a Vomit in the Evening, and next Day a Dose of some gentle Purge, as Rhubarb or Salts; to carry off these putrid, bilious Humours: And afterwards, in the Course of the Disorder, if the Patient was costive, and grew hot, restless, and uneasy, we either repeated the Purge, or gave laxative Clysters, which generally removed these Symptoms.—Frequently after the Operation of the Emetic, the Patient had some loose Stools, from the Gall Bladder’s being emptied in the Strainings to vomit. Such Stools were always bilious, as were commonly those procured by purgative Medicines.
After emptying the Bowels, we gave the cooling, and mild Diaphoretics, such as the saline and mindereri Draughts, joined occasionally with Nitre, or the Contrayerva Powders; while we made the Patient drink plentifully of warm diluting Liquors; which we found to answer in general better than any other Remedies: They brought the Remissions to be more evident, and the Paroxysms to be milder, at the same Time that they kept up a free Perspiration, as a Means to carry off the Distemper.
In some Cases we gave the Antimonial Powder, made of one Part of Tartar Emetic, and ten of the pulvis e chelis, in small Doses, from two to four Grains every four or six Hours. The first Doses of this Powder sometimes made the Patient sick, and acted as a Purgative, and kept up a free Perspiration; at other Times, it produced no visible Effect. In some Cases, where it was given early, it operated both by Stool, and as a Diaphoretic, and removed the Fever[75]; and it was of Use in others, towards the Decline of the Fever; but we were often obliged to lay it aside; for it either acted too roughly, or produced no visible Effect or Alteration in the Disorder.
When the Fever came to remit, we were obliged, for the most part, to continue the Use of the mild Diaphoretics, as before; for, although the Disorder put on a remitting Form, the Bark had very little Effect in stopping it[76], unless where the Fever changed into a regular Quotidian or Tertian Ague.—In the Year 1761, very few of these Fevers turned to regular Intermittents; but, in the Year 1762, the greater Part of them terminated in regular Agues, and were cured by the Bark[77].
In the Year 1761, we tried the Bark in various Forms in many Cases, where the Patient had been blooded and purged in the Beginning, and used the cooling Medicines; and where the Remissions were very clear: Yet it had no Effect in removing the Disorder, except in two or three Cases at Munster, where the Paroxysms assumed a tertian Form; for the most part, it made the Patients more hot and feverish, and we were obliged to leave off using it, as it was in Danger of changing the remittent into a continued Fever. However, it was of Service after the Fever came to a Crisis, and was going off; and Dr. Pringle has very justly observed, that it hastened the Recovery, and that those who used it were less subject to Relapses than such as did not; and therefore we commonly gave it in a convalescent State.—Before giving the Bark, I always found it of Advantage to give a Dose of Rhubarb, or of some other Purgative, or to mix some Rhubarb with the first Doses, so as to procure the Patient some loose Stools.
When either the Fever went on without Intermission, or changed into a continued Form, or the Patient continued hot and feverish through the Day, with a Head-Ach, and other feverish Symptoms, nothing answered better, after free Evacuations had been made, than to apply a large Blister to the Back; and to make the Patient drink freely of cooling diluting Liquors; which generally relieved the Head, and abated the Violence of the other Symptoms.
When a Purging came on in the Course of this Disorder, if there was much Fever, with a strong throbbing Pulse, Gripes and Pain of the Bowels, some Blood was taken away; and immediately after the Patient took a Dose of Salts and Manna, or of Rhubarb; and an Opiate in the Evening after its Operation: But if there was little or no Fever, or sharp Pain, Bleeding was omitted; and if the Patient complained of Sickness, a few Grains of Ipecacuana were given previous to the Purge.
After this, if the Purging was moderate, and did not sink the Patient, we did nothing to stop it; but if it was violent, we gave the mindereri Draughts with Mithridate, and the Chalk Julep in the Day, and an Opiate at going to Rest; and occasionally used the emollient and anodyne Clyster; and, if necessary, repeated the Emetic and Purge.
The Hiccup seldom appeared in this Fever till the Patient was reduced very low, and was commonly the Forerunner of Death. Some few, who had a Purging and Vomiting, were taken with a Hiccup, attended with Sickness, and Load at the Stomach, which seemed to depend on bilious Humours lodged in the Stomach and Bowels. This induced me to give a few Grains of the Ipecacuana; and to make the Patients drink an Infusion of Camomile Flowers till they vomited freely, and afterwards to take some mild Purge, or use laxative Clysters; after which they found themselves easier, and an anodyne Draught, with twenty or twenty-five Drops of the tinctura thebaica, put an End to the Hiccup. Others required the Use of Cordial Draughts, mixed with Opiates; and repeated Clysters and Fomentations, before they found Relief.—The Application of a Blister removed the Hiccup in one, after the above Remedies had proved ineffectual; as did the Musk Julep with Opium, and the Application of an aromatic Plaister to the Stomach, in another Patient.
Several of them complained of a burning Heat and Pain in making Water; which commonly went off by drinking freely of the Gum Arabic Decoction, with the dulcified Spirit of Nitre, and the Use of oily Draughts; though in some it required the Assistance of Opiates, and of Fomentations and Clysters, before it was got the better of.
The Symptom of Worms we were often obliged to neglect till the Fever was over, and then we treated it as formerly mentioned.
The Deafness, though not near so frequent in this as the Malignant Fever, was rather a favourable Symptom, and mostly went away of itself; though in a few Cases, where it continued long, we applied Blisters behind the Ears, or to the Neck, with Advantage.
Many, especially those who were brought low, complained, after the Crisis of the Fever, of Restlessness, and Want of Sleep; which, however, went off as their Strength returned: Where it fatigued them much, and kept them low, we gave a Cordial anodyne Draught at Night; and if that did not answer, commonly the Addition of a few Glasses of Wine in the Afternoon had the desired Effect.
Others, in their convalescent State, complained of such a Giddiness, and Lightness of the Head, that they could neither walk nor stand; others, of a Dimness of the Eyes. These Symptoms, for the most part, went off as the Patients gathered Strength: The Use of the Bark, with now and then a Glass of Wine, hastened the Cure; and in two or three Cases we were obliged to give a Dose or two of some gentle Physic, and to apply a Blister, before the Patient got the better of them.
As the Sick were recovering, it was common for them to complain of Pains of the Shoulders, Arms, and Legs, which also left them as they recovered their Strength; where they did not, the saline Draughts, and a low Diet, generally had a good Effect; and where it had not, we treated them as rheumatic Complaints.
When the yellowish Colour of the Countenance remained after the Fever, we kept the Patient on a low Diet; and his Body open by Means of the saline Draughts, with a few Grains of Rhubarb, or by giving Half a Drachm, or two Scruples of the Soap Pills with Rhubarb daily; which, for the most part, removed the Yellowness soon. Two only had a Jaundice remain after the Fever, and both were cured in a short Time.
In other Respects, the Treatment of this Fever, when it degenerated into a continued Form, had nothing particular in it; nor differed from the common Practice of giving cooling Medicines when the Fever was high, and supporting Nature by the Use of Cordials and Wine, and the Application of Blisters, &c. when low; and promoting such Evacuations as Nature pointed out for a Crisis.
