I have in cases of extreme weakness in premature children succeeded in preserving them by giving them every two hours for two or three days ten measured drops of raw beef juice, five of brandy, and two teaspoonfuls of breast milk. Medicine has no place in the management of these cases; the question is one entirely of warmth, food, and for a time the judicious use of stimulants.
Imperfect Expansion of the Lungs.—Children not premature and perfectly well nourished are yet sometimes feeble, breathe imperfectly, cry weakly, suck difficultly or not at all, and die at the end of a few days. Their lamp of life flickered and went out. Such cases are met with for the most part in conditions similar to those in which children are actually still-born; or now and then they take place when labour has been of unusually short duration, the child hurried into the world too rapidly; while in other instances it is not possible to account for their occurrence.
For a long time the nature of these cases was not understood; but rather more than sixty years ago a German physician discovered that air had entered the lungs but imperfectly; that perhaps a third, perhaps even as much as half, of the lungs had never been dilated, but had remained solid and useless; that in consequence the blood was but half-purified, and vitality therefore but half-sustained. The lungs, however, were found to have undergone no real change; they were not diseased, but if air was blown into them the dark solid patches sunk below the level of the surrounding substance, expanded, grew bright in colour and like a sponge from which the water has been squeezed, and crackled, or crepitated as the technical term is, from the air contained within them.
We breathe in health so without conscious effort that we never realise the fact that, according to the calculation of most competent observers, the mere elasticity of the lungs, independent even of the elasticity of the chest walls, opposes a resistance to each inspiration equal to 150 pounds avoirdupois in the grown man and 120 in the grown woman. The want of breath puts the respiratory muscles into play: the man takes a deep inspiration, and by this unconscious effort, he overcomes the resistance of the chest and the elasticity of the lungs. The new-born infant feels the same want and makes the same effort; but its muscular power is small, and its inspirations are often so feeble as to draw the air in some parts only into the larger tubes, while many of the smaller remain undilated, and much of the lung continues in the state in which it was before birth. The blood being thus but imperfectly purified, all the processes of nutrition go on imperfectly, the vital powers languish, the inspiratory efforts become more and more feeble, while the elasticity of the lung is constantly tending to empty the small cells of air and to oppose its entrance, and next the temperature sinks and the infant dies.
Cases in which this condition of the lungs exists usually present the history of the child from the very first having failed to utter a strong and loud cry like that of other children. Even after breathing has gone on for some time, such children usually appear feeble, and they suck with difficulty, although they often make the effort. An infant thus affected sleeps even more than new-born infants usually do; its voice is very feeble, and rather a whimper than a cry. In the cry of the healthy infant you at once detect two parts—the loud cry, suffering or passionate as the case may be, and the less loud back draught of inspiration. The French have two words for these two sounds—the cri and the reprise. The cri is feeble, the reprise is altogether wanting wherever expansion of the lung has to any considerable extent failed to take place, and you would hail this second sound as the best proof of an improvement in the child's condition.
If you watch the child with a little attention you will see that while the chest moves up and down, it is very little, if at all, dilated by the respiratory movements. The temperature falls, the skin becomes pale, and the lips grow livid, and often slight twitching is observed about the muscles of the face. The difficulty in sucking increases, the cry grows weaker and more whimpering, or even altogether inaudible, while breathing is attended with a slight rattle or a feeble cough, and the convulsive movements return more frequently, and are no longer confined to the face, but affect also the muscles of the extremities. Any sudden movement suffices to bring on these convulsive seizures, but even while perfectly still the child's condition is not uniform, but it will suddenly become convulsed, and during this seizure the respiration will be extremely difficult, and death will seem momentarily impending. In a few minutes, however, all this disturbance ceases, and the extreme weakness of the child, its inability to suck, its feeble cry, and its frequent and imperfect inspirations, are the only abiding indications of the serious disorder from which it suffers. But the other symptoms return again and again, until after the lapse of a few days or a few weeks the infant dies.
I have dwelt at some length on this condition because it is important to know that during the first few weeks of life real inflammation of the lungs or air-tubes is of extremely rare occurrence, and that the symptoms which are not infrequently supposed to depend on it are really due to a portion of the lung more or less extensive never having been called into proper activity. I may add that we shall hereafter have to notice a similar condition of the lung—its collapse after having once been inflated—as occurring sometimes in the course of real inflammation of the organs of respiration in early life, and forming a very serious complication of the original disease.
If the collapse of the lung is not so considerable as to destroy life within the first few hours or days after birth, the babe wastes as well as grows weaker and weaker, and this wasting coupled with the difficult breathing not seldom causes the fear that the child has been born consumptive and that its death is inevitable.
No such gloomy view need be taken. Collapse, or at least non-expansion of the lung to some extent, is by no means unusual: consumptive disease to such an extent in the new-born infant as to interfere with the establishment of breathing is extremely rare. The consumptive babe can suck, it is not so weak as the one whose lungs are imperfectly expanded; it has no convulsive twitchings, nor any of the strange head-symptoms which we notice in the former. It wastes less rapidly, it is feverish instead of having a lower temperature than natural, it seems less ill, and yet its death within a few weeks or months is absolutely certain; while the child whose lungs are not diseased but simply unexpanded may, if that accidental condition is removed, grow up to vigorous manhood.
The treatment of these cases is abundantly simple. The child who breathes imperfectly but ill maintains its heat. It must be kept warm at a temperature never less than 70°; it may, like the premature child, need stimulants, and all the precautions already mentioned as to feeding. Twice in the day it should be put for five minutes in a hot bath at 100°, rendered even more stimulating by the addition of a little mustard. The back and chest may be rubbed from time to time with a stimulating liniment, and an emetic of ipecacuanha wine may be given twice a day. The act of vomiting not only removes any of the mucus which is apt to accumulate in the larger air tubes, but the powerful inspirations which follow the effort tend to introduce air into the smallest vesicles of the lungs, and to do away with their collapse.
Let these directions be carried out sensibly, patiently, perseveringly, and three times out of four, or oftener still, the mother's ear will before many days be greeted by the loud cry, with its cri and reprise of which I have already spoken, and which assures her that her little one will live.
There are no other affections of the lungs so peculiar to the first month of life as to call for notice here. I shall have a few observations to make about malformations of the heart, and the precautions for which they call in the after-life of children; but they will find their fittest place in the chapter on Affections of the Chest.
