Observations on the Diseases of Seamen

by Sir Gilbert Blane

But though the fatality of this disease is discouraging, let us not despond, but rather redouble our diligence in observing what assistance and relief nature may admit of.

It is proper in this as in every other fever of this climate, to begin the cure by cleansing the first passages. This does not produce the same relief as in the common bilious fever, probably because there is a less free secretion of bile, and therefore less oppression from the collection of it.

With regard to blood-letting, the most that can be said in its favour is, that if there should be a hard throbbing pulse, with violent pain in the head and back, it is safe in the first twelve hours. This limitation is necessary, at least with regard to common seamen, who do not bear evacuations so well as officers and others, who are used to a better diet, and to whom the loss of blood has, in some cases, been found useful in the early stage of this fever. It is, however, in all cases extremely dangerous, except in the circumstances mentioned above. The blood is said to shew a buff in the beginning of the disease, but in the second stage, it is mentioned by a French author[106], that it hardly coagulates or separates. But even the appearance of a buff, without considering other circumstances, does not always argue the propriety of blood-letting[107].

The great object in the cure of this fever is, to bring the stomach to bear the bark. There are here wanting most of the circumstances that in the other cases forbid the use of it; for there is no preternatural quantity of bile in the stomach and intestines, nor is there a hot and dry skin, nor violent delirium. The only obstacle to its administration is the great irritability of the stomach, which is the most fatal symptom of the disease; and the principal part of the management of the patient consists in the prevention or removal of this. The stomach is to be treated with the utmost tenderness and attention. One gentle emetic at the beginning is all that is allowable; and as fresh collections of bile are less apt to occur, the repetition of it is less necessary.

It is best to abstain altogether from antimonial medicines, and to render every thing, whether food, drink, or medicine, as grateful as possible. The liquid most apt to stay upon the stomach is the juice of the acid fruits of the climate, such as[108] oranges and lemons. It happens frequently, however, that acids come to be loathed extremely, so as to nauseate the stomach and to encourage retching. In this case I have found a composition of wine and water with lemon juice and nutmeg, sweetened with sugar, and given warm, to be a very grateful and salutary drink. The patient sometimes prefers the decoction of farinaceous substances to every other liquid; and in one case in particular, which did well, the patient was led by taste to prefer warm water gruel to every thing else, and the great quantity he drank seemed to have a considerable share in his recovery, by keeping up a warm moist skin and producing a great flow of urine.

In order to check vomiting, the saline draught, in the act of effervescence, has been employed with evident advantage; but in most cases this symptom is so obstinate as to discourage all attempts to remove it. I have known magnesia in mint water have a visible effect in soothing the stomach, particularly when given immediately after some acid beverage.

I was informed by Dr. Young, physician to the army, that he found an infusion of chamæmile flowers one of the best medicines in this vomiting; and a surgeon of one of the line-of-battle ships informed me, that he also found advantage from it in alleviating this symptom. The French author above mentioned affirms, that milk, boiled with some flour or bread, given in the quantity of a spoonful at a time, and frequently repeated, had more effect than any thing he tried in stopping the vomiting in this fever. I have seen this symptom relieved by fomenting the stomach with stupes wrung from the decoction of bark, and sprinkled with camphorated spirits and tincture of bark[109].

But nothing I have ever seen tried had so great an effect in removing this irritability of stomach as a blister applied to it externally; and it is a remedy which, so far as I know, has not been hitherto recommended. In other fevers, when the head was not particularly affected, I preferred this part for the application of a blister, for it is in some respects more convenient than between the shoulders, and the stomach is the part more affected perhaps than any other in all fevers. But in this fever I was led to apply it to this part, both from its being affected in an uncommon degree, and from observing, upon inspecting the bodies of those who died, that the only morbid appearance that could be discovered was an inflammatory suffusion on the inner membranes of the stomach.

I have employed opiates both externally and internally to allay this symptom, but without the effect that might have been expected from so powerful a sedative.

As the stomach will seldom, even in the most favourable cases, bear such a quantity of bark as to subdue the disease, it must be exhibited in every other way that can be thought of, such as by clyster and by external fomentation, both of which I have employed with good effect. I used to order a pint of decoction of bark to be injected every three or four hours, and the fomentation to be employed nearly as often. I have heard of the decoction of bark being used as a warm bath with success; but I cannot decide concerning this practice from my own experience.
