The temporary difficulty of breathing which is felt in the early months, from nervous sympathy, needs scarcely any kind of treatment, as it passes off naturally in a short time. In severe attacks the same remedies may be used as for difficulty of swallowing before referred to. That which arises in the latter months, from pressure of the womb, can frequently be relieved only by the patient remaining as long as possible in certain favorable positions. I have known many who could never sleep except when propped nearly upright, by means of pillows and cushions, as immediately they assumed the recumbent position the upward pressure became so great they were nearly suffocated. In such cases the patient should be careful never to eat or drink to excess, nor take anything likely to produce wind, because the least increase in the size of the abdomen adds to the difficulty. The bowels should also be kept free, and nothing tight or heavy in the way of clothing should be worn. This difficulty is most frequently seen in those who have contracted chests, and in those who have been accustomed to wear corsets and tight dresses. A deformed pelvis may also give rise to it by forcing the womb above its usual position. Many females both create and increase this difficulty by binding themselves tighter than usual during pregnancy, under the mistaken idea that it enables them to support their burden so much easier. When the dyspnœa arises from a full habit the patient must live low, keep the body regularly bathed and rubbed, and the bowels freely open by an occasional seidlitz powder, or dose of Epsom Salts. If the difficulty becomes at any time suddenly great and alarming, the feet should be placed immediately in hot water, while the patient is upright; a mustard plaster should also be put upon the chest, and an opening injection of starch and Castor Oil administered as soon as possible. The usual practice in such cases is to bleed from the arm, to the extent of eight or ten ounces, and in case no other means give relief, this may be tried. COUGH.
