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.
