Importance of ascertaining that the uterus is contracted. As soon as the child is separated from its mother and removed, or even sooner, if this process has gone on slowly, we ascertain if the uterus has contracted: this we shall know by its feeling like a large hard ball behind the symphysis pubis: if there be one rule more important than another, it is this, for without it we cannot be certain of the patient’s safety for a single minute: so long as we feel the fundus to be hard, we know that the uterus is contracting, and that it will expel the placenta quickly, and ensure the patient against hæmorrhage; but if it be soft and relaxed, she cannot be considered safe even if their be no hæmorrhage; for the placenta may have been separated, and may be lying across the os uteri, or the os uteri itself may be contracted, or blocked up with coagula, so as to prevent the blood from escaping; it therefore collects in the cavity of the uterus in large quantities, to the imminent danger of the patient. Even where the uterus has contracted, the patient is not permanently safe, for it may again relax and grow soft, and hæmorrhage come on.
Management of the placenta. The placenta sometimes follows the child immediately, and occasionally is expelled by the same pain; usually, however, a few minutes intervene, during which time the uterus remains more or less in a state of inaction; it then begins to contract, and the dull and peculiar pains which characterize the separation of the placenta are now felt. The interval after the birth of the child varies considerably, and depends in many cases on the degree of rapidity with which the uterus has been emptied: hence in some cases we feel the fundus hard almost immediately, whereas, in others some considerable period elapses before it resumes its state of activity, a period which, if any separation of the placenta has already taken place, will be attended with the greatest danger. The occurrence of pains indicates fresh contractions, and therefore we should now examine to ascertain if the placenta has been detached. As a general rule it may be stated, that if we can reach the insertion of the cord with our finger we may presume that the placenta is ready to be expelled; if not, that it is still partially or wholly attached to the uterus. So long as this latter is the case, the less we meddle with the cord the better, for by pulling at it we only excite the os uteri to contract, and thus seriously impede its removal.
Where some time has elapsed without any symptoms of contraction coming on, we may excite the uterus by circular friction of the abdomen, fanning the face, or by sprinkling a little water upon it, &c.: if, however, the uterus is hard and yet the placenta not within reach, we may pull slightly at the cord, pressing it at the same time back with the fore-finger into the hollow of the sacrum; we thus bring it down in the direction of the pelvic axis, and generally succeed in moving it into the vagina. No violent effort should be made, as this would probably tear it off from its insertion into the placenta, but, by keeping a gentle pressure upon it, the placenta will slowly pass through the os uteri, and then come away without farther difficulty. Following the axis of the vagina, we now guide it downwards and forwards; and when it approaches the os externum, it should be seized with the finger and thumb, and rotated several times: the membranes are thus twisted into a rope, and are less liable to be torn in separating from the uterus. The uterus being now completely emptied, contracts into a hard ball of about the size of a child’s head. If, however (whether before or after the expulsion of the placenta) the uterus grows soft and swells, if the patient becomes pale and restless, and complains of faintness, sickness, load at the præcordia, darkness before the eyes, &c. we may be sure that hæmorrhage is going on. We refer to the chapter upon uterine hæmorrhage for the measures to be adopted.
Twins. Where there are twins, the above rules for ensuring the safe expulsion of the placenta require to be still more strictly observed: the uterus has been more distended, the mass of placenta is larger, and is attached to a much greater extent of surface than where there has been only one child: hence there is not only a greater liability to hæmorrhage, but if it does take place, will probably be much more dangerous. We cannot be too cautious how we extract the placentæ of twins: from the size of the mass, the uterus remains larger, and therefore less contracted: hence, if we venture to pull at the cord before being able to reach the placenta with our finger, we shall feel it yield; but this is not from the placentæ being detached and coming away, but from the fundus itself being pulled down with it—a state which would rapidly pass into inversion if the force were continued. In order to detach the mass more equally, we should twist the two cords together; by so doing there is less danger of their giving way. The same rotating movement should be used when the placentæ approach the os externum; the two bags of membranes are thus twisted together, and come away entire: if this be not attended to, the membranes are torn, portions of them are left adherent to the uterus, and come away some days afterwards in a half putrid state producing a fetid discharge, and sometimes considerable fever.
Treatment after labour. As soon as the placenta is expelled, the soiled and wetted sheet should be removed and a warm napkin applied to the external parts: the patient should remain thus for half an hour or more, and enjoy a little rest, or even a short sleep: by this time the nurse will have washed and dressed the child, and be ready to attend to the mother. The external parts should be sponged with warm water, her linen changed, and a broad bandage pinned firmly round the abdomen to give it the necessary degree of support. Where there has been great abdominal distension and more than one child, it is sometimes advisable to apply the bandage immediately after the birth of the first, in order to assist the uterus in expelling the second, and in contracting afterwards. The bandage, therefore, should be gradually tightened as the abdomen diminishes in size: without this precaution the removal of so much pressure from the abdominal circulation will be sometimes attended with alarming faintings. A similar effect may be produced by the patient incautiously sitting up in bed to take any refreshment which may be offered to her at this moment; she should be warned, more especially if she be a primipara, not to raise herself from the horizontal posture for a few hours after labour; at any rate, not until the bandage has been properly applied: from inattention to this point, cases have occurred where, on the patient’s sitting up immediately after labour, she has fallen back in a faint from which she never recovered; in other cases it has been attended by profuse hæmorrhage, which has instantly proved fatal. “The influence of position,” says Dr. Meigs, “in determining the momentum of blood in the vessels is well known to the Profession, but there are few cases where it is of more consequence to pay a profound regard to this influence than in the parturient woman. A uterus may be a good deal relaxed or atonic, and yet not bleed, if the woman lie still with the head low; whereas, upon sitting up suddenly, such is the rush of blood down the column of the aorta, the hypogastric and the uterine and spermatic arteries, that the resistance afforded by a feeble contraction is instantly overthrown, and volumes of blood escape with an almost unrestrained impetuosity: the vessels of the brain under such circumstances become rapidly drained, and the patient falls back in a state of syncope, which now and then proves immediately fatal.” (Philadelphia Practice of Midwifery, by Charles D. Meigs, M. D. p. 192.) Even if all these directions have been strictly obeyed, if every thing has gone well, and the uterus is firmly contracted, we are not sure of its remaining so: after the lapse of many hours it may again relax, and flooding come on, its power of contraction being impaired either by the exhaustion of the previous labour, the warmth of the bed, &c. It will, therefore, be desirable to adopt such measures, as will ensure the patient against this occurrence: in most cases it will be sufficient to keep the room moderately cool, and ensure a due degree of ventilation; but where the uterus has shown a disposition to relax, we know of nothing which guards the patient so effectually against hæmorrhage after labour, and enables us to leave her with so much confidence, as putting the child to her breast. The sympathetic connexion between the breast and the uterus is now well known; nor are there any means so certain of producing permanent uterine contraction as this natural act: it is a duty which nature instinctively prompts the mother to perform, not only for the preservation of her child, but for the safety of herself. We, therefore, make it a rule, whenever the patient intends to suckle her child (a duty which is performed more frequently now than it was a few years ago,) to have it put to the breast before quitting the house: the first excitement of the mother’s feelings towards her offspring is a favourable moment for the performance of this act, the erectile tissue of the nipple becomes turgid, the child takes the breast with ease, and the effect upon the uterus is not less certain than complete; even if the child sucks fairly well for only five minutes we feel satisfied, for we cannot call to mind a single case of hæmorrhage after the effects of this operation.
Lactation. When the wet clothing has been removed, and fresh linen substituted, the patient should be left to enjoy perfect quiet both of body and mind, in order that she may have some sleep, for “the refreshment of sleep seems to be the most powerful natural means of inducing full contraction of the uterus.”[72] After this, the child should be placed at her side, in order that it may enjoy the warmth of her body, and make another trial of taking the breast. That new-born animals are not able to maintain a sufficient degree of warmth, is seen by the care with which a bird shelters her young beneath her wings, and by the manner in which kittens, puppies, &c. crawl close to the mother’s abdomen to enjoy that degree of heat which of themselves they are unable to produce. Dr. Edwards has shown that the animal heat of a new-born infant is several degrees below that of the adult: the mother’s breast is, therefore, the natural place for it, where it can not only enjoy the necessary warmth, but take that nourishment which has been destined for its support at this early period. A child is capable of sucking the moment it is born; indeed, we would say, better at this moment than later, for the power of instinct in it is fully as great as in other animals; whereas, if not put to the breast soon after birth, but fed instead, it quickly loses it. A vigorous healthy child immediately seeks its mother’s breast, and if it does not find it, sucks at every thing which touches its mouth, even its own little hand or finger when presented to it: so strong is this instinct, that, on more than one occasion, we have known the child suck at the finger of the medical attendant when the head had only just cleared the os externum.
It has been, and even still is, a very general practice not to apply the child to the breast until the second or third day, upon the plea that there is no milk: a more erroneous and mischievous plan of treatment could not be devised, for it is a fruitful source of much injury as well of suffering both to the mother and her child. The child should be put to the breast, “whether there be signs of milk or not.” (White, on Lying-in Women.) There is always more or less thin watery fluid called colostrum which is admirably adapted to form the first nourishment of the infant; it is slightly purgative, and, therefore, well fitted to unload the bowels of the viscid green mucus, called meconium, which fills them. The colostrum has been variously described by authors; some speak of it as a thin watery fluid, others as a thick creamy milk: this difference depends in great measure upon the interval between the birth of the child and its application to the breast: where this has taken place early, as we have just recommended, the colostrum has almost always the thin watery appearance above mentioned; whereas, if some period of time has been allowed to pass before the child is applied, the breast begins to secrete a fluid containing a larger proportion of caseous matter, or, in other words a more perfect milk, which not being drawn off, the watery part of it is absorbed, leaving the thicker portion to be removed by the process of sucking. Instead of giving the child this bland and natural fluid when in a state best fitted for its delicate digestive organs, it is but too frequently the practice to make it swallow some soft sugar, or a tea-spoonful of castor oil, and follow this up with a little gruel. The effects of such treatment upon a stomach which has never yet received food may be easily imagined; the digestive function becomes deranged, pain is excited, acid is secreted, gas is disengaged, flatulence, diarrhœa, &c. are the result, with all those manifestations of gastric irritation, such as strophulus, aphthæ, colic, &c. from which new-born children are made to suffer so severely.
Besides the above advantages in applying the child thus early to the breast, there are others of even greater importance which require to be mentioned. The breast is not yet distended; it is soft and conical, and therefore in a most favourable condition for being drawn; the child can seize the nipple and draw it out with ease, and by thus straightening the lactiferous tubes it commands a ready flow of their contents. By the gentle irritation of sucking, an earlier secretion of milk is excited, and being drawn off as fast as it is formed, the breast is never distended by an accumulation of milk. On the other hand, where some time has elapsed before putting the child to the breast, it will have in great measure lost the instinctive desire to suck; the breasts have become distended and painful; instead of being soft and conical, they are now hard and flattened, the nipple is shortened, or even sunken in; and if the child does succeed in drawing it out, it is at the expense of severe suffering to the mother. The process of sucking in this state of the breast is very difficult; a considerable effort is required to elongate the nipple, and the thin delicate skin which covers it is abraded; excoriations and deep fissures round the base of it are produced, and each application of the child is one of absolute torture. In many cases, partly from having been fed, and partly from the difficulty it meets with, the child refuses the breast altogether; in others, the suffering is so severe as to oblige the mother to discontinue the attempt. The breasts now increase in size and hardness, producing great pain from their weight and tension; hard painful knots from the distended tubes and vessels are felt in different parts, and the pain and dragging extends to the axillæ, the glands of which are also swollen and painful.
Milk fever and abscess. By this time, or even earlier, the patient will in all probability have been attacked with a smart shivering fit followed by a hot and then a sweating stage, and accompanied with headach and febrile excitement of the circulation. This is the febris lactea, or milk fever, an affection which, at one time, was very generally supposed to be necessary for establishing the secretion of milk: experience, however, has shown that it chiefly results from neglect in not putting the child to the breast sufficiently early; the secreted milk has been in part absorbed into the system, fever has been induced, and the patient has been relieved by the natural crisis of a sweating stage. The febrile excitement will be considerably moderated, and the tension of the breasts relieved, by the action of saline laxatives: the shoulders which are usually kept warm for the purpose of promoting the secretion of milk, should now be clothed more lightly; the relief, however, is but too frequently partial, the breasts still remain large and painful; the process of suckling is just as difficult as before, and the indurated spots increase in hardness, sensibility, and extent; throbbing and darting pain is felt in the part, the skin over it becomes hot and red, and at length presents that shining glazy look which but too surely indicates the formation of matter beneath, a circumstance which is still farther proved by the œdematous feel of the part, or by the presence of actual fluctuation.[73]
Where the breast is capable of being drawn, whether by the child or by artificial means, the application of a cold evaporating lotion, and the frequent exhibition of saline laxatives, will generally suffice to check the determination of blood to the breast, and diminish the secretion of milk; but where these means fail to reduce its size and hardness, it should be frequently rubbed with volatile liniment, and then enveloped in a hot linseed-meal poultice: this may be advantageously made with Goulard, and changed every two or three hours, keeping up a brisk action upon the bowels, as before-mentioned.[74]
