If the child's surroundings cannot be changed and lie is subjected to the same conditions of possible reinfection, it may be a wise precaution, much like the prophylactic administration of quinin in malarial regions. If a child has developed a cardiac inflammation during any disease, the treatment is that previously outlined.
Enough should be given; too much should not be given. Strychnin will sometimes whip up a tired heart and tide it over periods of depression, but it is a whip and not a cardiac tonic.
When Mr. Worthington had finished it, and had addressed both the envelopes, his shame and vexation had, curious to relate, very considerably abated. Not to go too deeply into the somewhat contradictory mental and cardiac processes of Mr.
Also, atropin sometimes quiets cardiac pain, but it will not steady the heart, may irritate it, and will increase vasomotor tension, although peripheral nerve irritation may be diminished. Hence a fair dose of morphin hypodermicaly with a small dose of atropin, if respiratory depression is feared, is a physiologic method of bettering the condition.
It is not proposed here to describe the condition of sudden cardiac failure, or acute dilatation during disease, or after a severe heart strain, but to describe the terrible cardiac agony which occurs, sometimes repeatedly, with many patients who have valvular lesions. These patients may not have the symptoms of loss of compensation.
Now the Patsys that come to free wards of city hospitals are very rare; and the superintendent and staff and nurses were interested beyond the usual limits set by their time and work and the professional hardening of their cardiac region.
If it is in excess, measures directed to bring it to the pathological norm should be instituted, but if the pressure found proves to be the pathological norm it is a bitter mistake to lower it, be the pressure what it may. If it is lowered below the pathological norm, all manner of disturbed cardiac action, etc., may result.
That nearest the orifice of the oesophagus is the broadest, and appears to act occasionally as a valve, so that the part beyond may be considered as an appendage similar to that of the peccary and the hog. The membrane of the cardiac portion is uniformly smooth; that of the pyloric is thicker and more vascular." Lectures on Comparative Anatomy, by Sir EVERARD HOME, Bart. 4to. Lond. vol. i. p. 155.
If, after one has been driving a motor car or even sitting at rest in one which has been going at speed or has come unpleasantly near to hitting something or to being run into, it is noticed that the little period of cardiac disturbance and chest tension is greater than it should be, the heart needs resting.
The decision can be made only at the bedside, and then mistakes, many times unavoidable, are often made. In all conditions of shock with cardiac failure, the blood vessels of the abdomen and splauclinic system are dilated, and more or less of the blood of the body is lost in these large veins, and the peripheral and cerebral blood pressure fails.
