An Account of the Diseases which were most frequent in the British military hospitals in Germany

by Donald Monro

In Winter 1761, we had but very few Agues in the Hospitals; but on the Return of the Troops from the Expedition into Hesse-Cassel, and during the Spring, some (though not many) were attacked with Quotidian and Tertian Agues, and but very few with Quartans.—In July and August they were more frequent, and accompanied with more bilious Symptoms. At Bremen, during the latter End of Autumn, and throughout the Winter and Spring 1762, we had Agues of all Sorts, and many inveterate Cases; and all this Spring, and during the Summer and Autumn, the Ague was the epidemic Disorder all over Westphalia, as well as among the Troops.

In Spring 1761, what Agues we had were mostly Tertian, some Quotidian, and but two or three of the Quartan Kind. They were, for the most part, mild, and yielded to the Bark.—Some of them began in the Form of a continued Fever; but after Bleeding, and the Use of the cooling Medicines for a few Days, they began to remit, and at last ended in regular Quotidian or Tertian Agues: Others, at first, appeared in Form of Remittent Fevers, attended with a strong throbbing Pulse; but changed to regular Intermittents by pursuing the antiphlogistic Method of Cure; and some from the Beginning assumed the Type of Quotidian or Tertian Agues, but often attended with a good deal of Fever, for the first two or three Days; and some had a slight Delirium in the Time of the Paroxysms, and the Pulse was not quite settled in the Intervals. In such Cases, where the Patient was strong, nothing answered so well as to take away some Blood; and to give the saline Draughts with Nitre till the Fever was moderated, before we gave the Bark.

In general, there is a Prejudice against bleeding in Agues, after they become regular; but I have always observed, both in England and in Germany, that where Patients are strong and plethoric, and the Fever in the Paroxysms rises high, or the Pulse remains quick in the Intervals, that taking away more or less Blood, and giving the antiphlogistic Medicines in the Beginning, eased the Patient, moderated the Fever, and made it safer to give the Bark soon; and I never saw the least Inconvenience from the Practice; but, on the contrary, have seen several Intermittent Fevers change into continued ones from the Neglect of this Evacuation; and have seen Cases where the Bark, instead of stopping the Ague, rather increased the Fever, till the Patient was blooded, and had pursued the antiphlogistic Method for some Time; after which the Bark had its proper Effect, and put an End to the Disorder.

As soon as these Agues became regular, and the Patient was quite cool, and free from any Fever in the Intervals, we gave the Bark; which soon put a Stop to the Paroxysms, without the least bad Consequences; but, before giving the Bark, we always took Care to empty the first Passages by the Use of Emetics and Purgatives, where there was no Symptom to forbid their Use: In Cases where the Patient was weak, and the Fits so violent as to make it necessary to stop the Ague, before we had Time to administer Emetics or Purgatives, we added so much Rhubarb to the first Doses of the Bark as procured the Patient some loose Stools, as recommended by Dr. Mead[82]; which did not prevent its stopping the Ague, at the same Time that it answered the End proposed of carrying off any putrid Humours that might be lodged in the Intestines.

In England, Vernal, Quotidian, and Tertian Agues, frequently go off after Bleeding, and taking some Emetics and Purges, and the saline Draughts, and cooling Medicines, for some Time, without the Use of the Bark; but in Germany very few yielded to this Treatment, and we were obliged to give the Bark[83] before we could put a Stop to them.

In the End of July, and Beginning of August, the aguish Cases we had at Munster continued to be of the Quotidian or Tertian Kind. The greatest Part of them began in the Form of continued Fevers, tending more to the bilious Kind than the preceding Months, and many of the Sick had bilious Vomitings in the cold Fits; and the Agues we had in Spring, and during the Campaign 1762, were of the same Nature, and required the same Treatment.

Those Cases, which began in the Form of continued Fevers, were treated as such till they began to have regular Intermissions; they then yielded to the Bark.

Some were attended with the Dysentery; and the Purging and Gripes were most severe on the Days of the aguish Paroxysms. In such Cases, we were frequently obliged at first to neglect the Ague, and to treat the Disorder entirely as a Flux. Where there was much Fever, the Patient strong, and the Pains in the Bowels acute, we ordered Bleeding; and after it a gentle Emetic, and some Doses of the saline oily Purge, or of Rhubarb; and gentle Opiates in the Evening, and other Medicines proper in the Dysentery, till its Violence was abated, before we gave the Bark: though in some Cases, where the aguish Paroxysms were very severe, and helped to increase the Purging, and the Patient was in Danger of sinking, we gave the Bark, notwithstanding the Flux still continued; and the Method we followed was the same as that I formerly mentioned, where it was complicated with the Malignant Fever; which was to give the Bark, mixed with Diascord, and Opiates, or other Medicines proper for the Dysentery, in the Intervals between the Purges.
