“Artificial respiration, as well as percussion and compression of the
different parts of the body, were immediately employed with energy; and,
after continuing the means for a short time, the circulation was
observed to be returning, and the act of respiration was several times
performed. The state of inanimation, however, speedily returned; but, by
the employment of the same means as before, with the use also of
galvanism, the circulation and respiration were again restored. Quickly,
however, the patient fell into the same state as at first, but was again
restored by the same means.
“In a few minutes the state of inanimation again returned, when the
external jugular vein, which on the right side was very turgid, was
opened, and tracheotomy was performed, and the lungs inflated. The
patient was also placed in a warm bath, at the temperature of 104°,
artificial respiration being kept up all the time. All, however, was of
no avail.”[92]
At the examination of the body, the following are amongst the
appearances noted. “The venæ innominatæ and vena cava superior were full
of blood, and probably would have been distended, but that two or three
ounces of blood had flowed into the coffin from the opening made into
the external jugular vein. The right auricle and ventricle were
distended with blood, and would probably have been more so but for the
escape of blood mentioned above. The left auricle and ventricle
contained very little blood; the left ventricle was perfectly contracted
in the rigor mortis. The heart was of full size. It appeared in every
part natural in its texture, and as if it had possessed full power. Its
valves also were all healthy; neither could any disease be found in any
of the chief bloodvessels within the chest. All the blood, however, was
fluid, and it remained without coagulation after its escape from the
heart and vessels. It had also a brownish purple hue, much like that
which is commonly observed in the spleen: none of it, when thinly spread
out, presented the ordinary dark, black, or crimson hue of venous blood.
Both lungs were attached by old adhesions about their apices and
posterior surfaces, but these were of small extent. Their texture was
healthy, but they appeared more than usually collapsed and dry. Their
bloodvessels were not over filled.”[93]
In this case, every precaution seems to have been taken, except that one
which is most essential of all, of regulating the proportion of vapour
in the inspired air. It had always been made a great point in St.
Bartholomew’s Hospital to attend to the pulse very carefully,[94] and on
this occasion it was closely examined, but only, as in some other cases,
with the result of being able to note the moment when it suddenly
ceased.
