PREMATURE EXPULSION OF THE FŒTUS.

Abortion.—Miscarriage.—Premature labour.—Causes.—Symptoms.—Prophylactic measures.—Effects of repeated abortion.—Treatment.

The uterus does not always carry the ovum to the full term of pregnancy, but expels it prematurely. This expulsion of its contents may occur at different periods, and is characterized accordingly: thus, among most of the Continental authors, it has been divided under three heads; those cases which occur during the first sixteen weeks coming under the head of abortion; those which occur between this period and the twenty-eighth week are called miscarriages; and when they take place at the latter period, until the full term of utero-gestation, they receive the name of premature labours.

It is perhaps useful to distinguish those cases of premature expulsion which occur before from those which occur after the fourth month, inasmuch as they seldom prove dangerous before that time, from the diminutive size of the ovum and from the slight degree of development which the uterine vessels have undergone; whereas, after this period the hÆmorrhage is more severe, and the general disturbance to the system greater. In other respects it will be more simple to divide premature expulsion of the ovum under two heads only; those cases which happen before the twenty-eighth week, or seventh month, being termed abortions, and after this period (as before) premature labours. This division is highly important in a practical point of view, since it marks the period before which the child has little chance of being born alive; whereas, after this date it may with care be reared.[61] A foetus may be expelled, at a very early stage of pregnancy, not only alive but capable of moving its limbs briskly for a short time afterwards, but it is unable to prolong its existence separate from the mother beyond a few hours. Cases do occur now and then where a child is born in the sixth month, and where it manages to struggle through, but these are rare, and must rather be looked upon as exceptions to the general rule.

Abortions usually occur from the eighth to the twelfth week, a period which is decidedly the least dangerous for such accidents. “The liability to abortion is greater in the early than in the later periods of pregnancy; for as the union between the chorion and decidua is not well confirmed, as the attachment of the latter to the internal face of the uterus is proportionably slight, and as the extent of surface which the ovum now presents is very small to that which it offers in the more advanced state of pregnancy, and as it can of course be affected by smaller causes, it will be seen that a separation will be more easily induced, and prove much more injurious to the well-being of the embryo, than a larger one at another stage.” (Dewees, Compendious System of Midwifery, § 929.) Abortions coming on at a later period, viz. from the sixteenth to the twenty-eighth week, which corresponds to the second division, or miscarriages, of the continental authors, are not only more dangerous than abortions at an early stage, for the reasons above-mentioned, but also than premature labours, as in this last division the uterus has attained such a size as to make the process rather resemble that of natural labour at the full term.

Causes. Premature expulsion may be induced by a great variety of causes, which may be brought under the two following heads: those which act indirectly, by destroying the life of the embryo, and those which act directly on the uterus itself. These various causes may be general or local; the process of nutrition for the growth and development of the embryo may be defective and scanty, from general debility or disease: hence, whatever depresses the tone of the patient’s health renders her liable to abortion by causing the death of the embryo. Thus, dyspepsia and derangement of the chylopoietic viscera; debilitating evacuations; depressing passions of the mind; bad or insufficient nourishment; intense pain, as in toothach; severe suffering from existing disease, especially where the health is much broken down by some chronic affection; syphilis, and febrile attacks, all act as indirect causes of abortion.[62] Salivation from mercury not unfrequently has a similar effect; in some instances, however, febrile affections appear to act much more directly, stimulating the uterus to powerful contractions and rapid expulsion of its contents. The symptoms which indicate the death of the child have already been detailed in the chapter upon that subject.

The period which may elapse between the death and the expulsion of the embryo varies exceedingly: in the early months the one usually follows the other pretty quickly, owing probably to the slight attachment of the ovum to the uterus; during the middle third of pregnancy the interval may be of considerable duration, and cases every now and then occur where the foetus is retained, not only several weeks, but even some months after its death; whereas, during the latter third of pregnancy, expulsion follows the death of the child after a short interval, seldom exceeding two or three days; for now the weight of the dead foetus speedily irritates the uterus to contraction, and, as has been observed by Smellie, the membranes, running gradually into putrefaction, and being now unable to bear the weight of the liquor amnii, burst, and expulsion soon follows.

Among the causes which act locally in inducing premature expulsion by first destroying the child, may be enumerated external violence applied to the abdomen, such as blows, falls, and other violent concussions; these act indirectly by producing separation of the ovum from the uterus, and thus destroying the life of the child. Under the same head may be classed all violent exertions, as lifting heavy weights, straining to reach something high above the head, &c. The mere act of walking, when carried to such an extent as to induce exhaustion, will suffice, in weakly delicate females, to bring on expulsion; sudden and violent action of the abdominal muscles, when excited by a half-involuntary effort to save herself from falling, or receiving any other injury, may produce a similar effect: if the foetus be so young that its movements cannot be felt by the mother, she feels from this moment more or less pain in the pelvis, with a sensation of weight and bearing down; and this, in all probability, will be followed by a discharge of blood from the vagina: where pregnancy has sufficiently advanced for the motions of the foetus to be perceptible, the mother will frequently feel them in an unusually violent degree for a short time immediately after the injury, and then they cease entirely.

Premature expulsion may also be induced immediately without the previous death of the child, by causes which directly excite the uterus to action: thus, various violent mental emotions, as rage, joy, horror, may act in this manner, although they may also act more indirectly; sudden exposure to cold, as sudden immersion in cold water, will occasionally produce it instantly. Irritation in the intestinal canal will directly excite uterine contraction; hence an attack of dysentery is frequently a cause of abortion, and we not unfrequently meet with patients who are liable to this affection in every pregnancy: a similar effect may be produced by the improper use of drastic purgatives, which irritate the lower bowels, viz. aloes, scammony, savin, &c.; or the uterus may, in some cases, be excited to contract from the peculiar action of secale cornutum. On the other hand, a loaded state of the bowels equally predisposes to abortion, by impeding the free return of blood from the pelvis. A state of general plethora acts in the same manner; and this is more particularly the case if it takes place at what would, in the unimpregnated state, have been a menstrual period; for, occurring in conjunction with the increased vascular action which prevails at these periods in the uterine system, it produces, as it were, an apoplectic state of the uterine sinuses, which form the maternal portion of the placenta; blood is extravasated between the ovum and uterus; their connexion is more or less destroyed, and the death of the foetus becomes unavoidable: hence, in these cases the expulsion may result either from this latter circumstance, or from the uterus being irritated to contract by the effused blood between itself and the membranes.

In patients who have suffered from attacks of dysmenorrhoea in the unimpregnated state, the irritable uterus, when pregnant, is very apt to contract upon its contents and expel them. This usually happens at what would have been a menstrual period, and not unfrequently takes place so soon after impregnation as merely to be looked upon as an unusually severe attack, the little ovum having been imperceptibly expelled among the discharges. Under this head must be brought those cases of spasmodic affection of the uterus, which Dr. Burns has described, and where, from the diminutive size of the ovum, the case has rather resembled one of menorrhagia. Cases of abortion are also mentioned by authors where the uterus is stated to be incapable of undergoing the necessary dilatation and increase of size which pregnancy requires; but we are strongly disposed to refer them to the above head of great uterine irritability, as we neither know of any diagnostic marks which will enable us to detect this condition during life, nor are we aware of any physical condition of the uterus short of actual disease, to be detected after death, which can produce this inability.

The uterus may be also excited to expel the foetus, without its previous death by local causes, as acute leucorrhoea, or other inflammatory affections of the vagina, by inflammation and other affections of the bladder, as calculus, &c. Too frequent sexual intercourse during the early months of pregnancy is peculiarly liable to excite abortion: this is especially observed among primiparÆ of the better ranks, where, from luxurious living, &c., there is but little physical strength in proportion to the great irritability of the system: hence we find that a fifth, or even a fourth, of these females abort in their first pregnancies. In conclusion we may briefly state that the same circumstances which in the unimpregnated condition produce menstrual derangement and other disorders of the uterine system, now act as so many causes of abortion.

The sudden cessation of the breeding symptoms, with sense of weight and coldness in the lower part of the belly, flaccid breasts, pain in the back and loins, and discharge of blood from the uterus, are pretty sure signs of abortion: they are those which are “produced by separation of the ovum and contraction of the uterus,” (Burns;) the one is attended by hÆmorrhage, the other by pain. Although these are two chief symptoms which characterize a case of threatened abortion, and although they must necessarily be present more or less in every instance where premature expulsion actually happens, still neither of them, either separately or conjointly, can be considered as a certain proof that the uterus will carry its contents no longer. Cases not unfrequently happen where patients have repeated attacks of hÆmorrhage during the early months of pregnancy, and sometimes to a considerable amount, without any apparent disturbance to the process of gestation, and are delivered of a living healthy child at the full term: on the other hand, we have known instances where the pain of the back was severe, and where, on assuming the erect posture even for a minute, the sense of weight and bearing down in the lower part of the abdomen was so great as to make the patient fear that the ovum was on the point of coming away; still even these threatening symptoms have gradually subsided, and the pregnancy has continued its natural period. Puzos considered that neither pain nor hÆmorrhage were necessarily followed by expulsion. (MÉm. de l’Acad. de Chir. vol. i. p. 203.) When, however, both occur together, and to a considerable extent, the case must be looked upon as one of at least doubtful if not unfavourable termination. Where pain comes on at regular intervals, with hardness of the uterus, and dilatation of its mouth, this is a serious symptom, for it shows that the uterus will no longer retain its contents, but is evidently preparing to expel them.

The part of the ovum at which the separation of it from the uterus has taken place, not only determines which of the above symptoms will appear first, but also the probability of expulsion. “When a considerable separation takes place, as must be the case when it commences at the upper parts of the uterus, pain will more likely occur than when it happens near the neck; hence we sometimes have pain before the blood issues externally. The uterus in this instance suffers irritation from partial distension from the blood insinuating itself behind the ovum; contraction ensues; the blood is thus forced downwards, and is made to separate the attachment between the ovum and the uterus in its course, until it finally gains an outlet at the os tincÆ. In consequence of the uterus being excited to contraction, the friendly coagula which may have formed from time to time are driven away, and the bleeding each time is renewed and accompanied most probably with increased separation of the ovum, until at last from its extent the ovum becomes almost an extraneous body, and is finally cast off. Hence a separation at or near the os uteri will not be so dangerous, and in all probability there will be hÆmorrhage without pain, which is the contrary when it takes place near the fundus.” (Dewees, Compend. System of Midwifery, § 981, 982.) The pain during the abortion is sometimes exceedingly severe, and not unlike that of dysmenorrhoea: this is probably owing to the violent contractions of the uterus, which are required to dilate the os and cervix before the ovum can pass: they are frequently attended with nausea, vomiting, and fainting, and sometimes with more or less general fever and local inflammatory action; the pain is generally attended with much irritability of the bladder, and frequent desire to pass water; the pulse is mostly quick and small, and where there is arterial excitement, it is sharp and resists the finger.

Treatment. The treatment of premature expulsion consists in, 1, that which is intended to guard the patient against its occurrence, or prophylactic; and 2, in that which is required during an attack.

A knowledge of the various causes of premature expulsion will materially assist us in the prophylactic treatment; under all circumstances, even where there is not the remotest fear of such an accident coming on, it is nevertheless highly important to pay strict attention to the state of the stomach and bowels, for these are almost always more or less influenced by the presence of pregnancy; the vomiting and sickness must be relieved in the manner already pointed out under the chapter on the Treatment of Pregnancy; the bowels, if constipated, must be moved by the mildest laxatives, such as castor oil, Confect. sennÆ, or a Seidlitz powder; and thus all sources of irritation in the primÆ viÆ prevented as far as possible. The patient must carefully avoid every thing which may excite the circulation, such as violent affections of the mind, rich indigestible and stimulating food, violent exertion, &c. The diet should be light, nourishing, and moderate; heavy meals must be forbidden, and especially suppers; she should keep early hours, take gentle and regular exercise, and in fact, endeavour by every means in her power to raise her health to a full degree of tone and regularity. In those patients who have already miscarried in their previous pregnancies, these precautions must be enforced with double vigilence; for the system becomes exceedingly irritable, and the uterus soon acquires, as it were, a habit of retaining its contents only to a certain period, and then prematurely expelling them. When this is the case, it becomes exceedingly difficult, and is often actually impossible, to make it carry the ovum to the full term of utero-gestation, and, despite of the greatest care, the symptoms of premature expulsion will come on at about the same time at which they occurred in former pregnancies, and sometimes to the very same week.

In the treatment of such cases, where there is so much liability to abortion, we must first examine the precise condition of the circulation, and ascertain whether it be above or below the natural standard of strength; for as abortion may arise from very opposite conditions of the circulation, our treatment must consequently vary. If there be signs of arterial excitement, a small bleeding may be necessary; it unloads the congested vessels, diminishes the force of the circulation, and therefore also the chance of an extravasation of blood between the uterus and ovum; the bowels must be kept open by cooling saline laxatives, and the circulation may be still farther controlled, by the use of nitre two or three times a day. The diet must be spare; she must take regular exercise in the open air, wear light clothing, dress loosely, and sleep upon a hard mattress.

In these cases we are often warned that congestion of the uterine vessels is present, by pain and throbbing, and sense of fulness in the groins; leeches applied to these parts give much relief, and frequently render venesection unnecessary. Tight lacing ought to be strictly prohibited in all cases of pregnancy, particularly where there is a disposition to plethora: among other bad effects, it prevents the proper development of the breasts, the nipples are pressed so flat as to be nearly useless, the child being unable to get sufficient hold of them: this may in some degree be avoided, by putting thick ivory rings upon the breasts, and thus shielding the nipples from injurious pressure. It will, however, be much better to have the dress made loosely, to allow for the development of the breasts, which takes place during pregnancy; for there can be little doubt, that irritation of these glands is very liable to be followed by a corresponding state in the uterus.

The common but erroneous notion that it is necessary to take an extra quantity of nourishment for the support of the child as well as of the mother must be strenuously opposed. Nature contradicts it in the most striking manner; for, by the nausea and sickness which most women experience during the first half of their pregnancy, she raises an effectual obstacle to any error of this kind. “It certainly cannot be intended for any other purpose, since it is not only almost universal, but highly important when it occurs, as it would seem to add much to the security of the foetus; for it is a remark as familiar as it is well grounded, that very sick women rarely miscarry; while on the contrary, women of very full habits are disposed to abortion, if exempt from this severe, but as it would seem, important process.” (Dewees, on Children, § 45.)

Where the case has become one of habitual abortion, the patient’s only chance will be by living separate from her husband for twelve or more months: the uterus, not being exposed to any sexual excitement during this period, becomes less irritable, and it gradually loses the disposition which it has acquired of expelling its contents prematurely. In such a case, when pregnancy has again commenced, it requires to be watched most narrowly; every possible source of irritation must be removed by the strictest attention to diet and regimen, and the patient must make up her mind to be entirely subservient to the rules laid down by her medical attendant. Although the chances are against her escaping without premature expulsion, still we are not to despair, experience showing that cases every now and then occur where the patient has gone the full term of pregnancy in safety, in spite of repeated previous abortions. Dr. Young of Edinburgh, in his lectures on midwifery, describes a case where the patient actually miscarried thirteen times, and yet bore a living child the fourteenth time.

On the other hand, where the condition of the patient evinces a state of strength considerably below the natural standard, we find a very different set of symptoms to those which have been just described, requiring opposite treatment: the face is pale and even sallow; the pulse is soft, small, and irritable; the tongue pale and flabby; the digestion impaired; the bowels torpid; and the extremities cold: fatigue, or rather a sense of exhaustion, is induced by the slightest exertion, and this is attended with dull, heavy, dragging pain about the pelvis and loins, and a feeling as if the contents of the abdomen required more support, and were disposed to prolapse either by the rectum or vagina, on her maintaining an upright posture for any length of time.

Even at a very early period of pregnancy, there is the sensation of a weight in the lower part of the abdomen, falling over to that side which is lowest, as we described among the signs of the death of the foetus at a later period, resulting in all probability from a loss of tone and firmness in the uterus. In this state, if nothing be done to restore the mother’s strength, the embryo will inevitably perish, and expulsion follow, sooner or later, as a necessary result.

In all cases where pregnancy occurs, in a weakly delicate woman, measures should be taken to increase the general tone of health, in order to fit her for going through this process safely, by removing her to the country, or to the sea-side, or to some watering place, where she will have the opportunity of drinking a mild chalybeate, and enjoying a purer air. Where it is even hazardous to move her, she should be put upon a course of mild chalybeates. The food should be light and nourishing, and a glass or two of wine or mild ale, may generally be taken with advantage. Where she can bear it, tepid salt-water bathing, or sponging, will have the best effects.

“For a number of years, (says Mr. White of Manchester,) I have been convinced of the good effects of cold bathing, not only in preventing miscarriages when every other method has been likely to fail, but other disorders which are incident to pregnant women, and generally attendant upon a weak lax fibre. I don’t mean the cold bath in the greatest extreme, but such as that of Buxton or Matlock, or sea-bathing, or bathing in a tub in the patient’s house, with the water a little warmed. I have frequently advised my patients to bathe every other day, at a time when the stomach is not overloaded, and not to stay at all in the water; to begin this process as early as possible, even before they have conceived, as there will be then no danger from the surprise, and continue it during the whole term of pregnancy; and several have bathed till within a few days of their delivery.” (White, on Lying-in Women, p. 70.) Where exercise can be taken without fear, it should be done regularly but cautiously, so as not to induce fatigue or exhaustion, which is the very effect we must be so careful to avoid; in fact, every means and opportunity should be used of recruiting the powers and the vigour of the system. In proportion as the strength increases, so does the irritability diminish; the uterus becomes less sensitive to external impressions, and can, therefore, bear its gradual development without being excited to contraction; the foetus receives its due supply of nourishment; the feeling of relaxation and deficient support of weight, and bearing down, go off as health returns; and by thus keeping up the powers of the system to the proper standard, it will be enabled to continue the process of pregnancy to the full term.

Although some women recover very quickly after an abortion, and appear for the time to suffer but little from its effects, they seldom escape with impunity, more especially if it has been repeated more than once: anÆmia, with its varied train of anomalous symptoms and concomitant gastric and cerebral disturbance, profuse leucorrhoea, menorrhagia, and dismenorrhoea, are some of the more direct results of repeated abortion; we may also enumerate prolapsus uteri, inflammation of the cervix, with induration and scirrhus, as the more remote effects.

In the treatment of a case where expulsion is threatened, our object will be either to stop that process in time to save the life of the foetus, or if this cannot be attained, to carry it through, in such a manner, as to expose the mother to as little danger and injury as possible.[63] In the first instance, we must be guided nearly by the same rules as in the prophylactic treatment: if there be considerable arterial excitement, and evidence of general plethora, a small bleeding will be useful in restoring a calm to the circulation; the most perfect quiet of body and mind must be insisted upon; the patient should lie upon a hard mattress, and be covered with as little clothing as is consistent with safety; she must refrain from all exertion, and strictly maintaining the horizontal posture for a considerable time. The indications for our treatment will be, 1. to remove every thing which may, in any degree excite the circulation, and, 2. to prevent the contraction of the uterus. Stimulants of every description, and animal food must be forbidden; the bowels must be opened by gentle saline laxatives; and if the pulse still betrays any sharp or resisting feel to the finger, small doses of nitre may be taken as already recommended. When the circulation has become perfectly calm, and every trace of excitement allayed, opiates will prove of inestimable value: they stop any disposition to uterine contraction, and remove the pain in the back and loins which this will cause. The form which we prefer is the Liquor Opii Sedativus, as being more sure in producing a sedative effect than common laudanum, while at the same time, it produces less irritation and derangement in the stomach and bowels.

A moderate discharge of blood from the vagina, although showing that a separation has taken place between the ovum and the uterus, cannot be looked upon as an unfavourable sign, for it relieves the pelvic vessels, diminishes the pain in the back, and makes the patient feel more light and comfortable; but if it be at all brisk, and continues so after the employment of the above remedies, if also there be heat and throbbing in the region of the uterus, it will be necessary to apply cloths wrung out of cold water to the lower part of the abdomen and vulva, and to the groins and sacrum; and this treatment must be continued in full force until the symptoms of congestion have abated, and the discharge lessened or stopped.

If the hÆmorrhage be really profuse, it shows that the separation of the ovum from the uterus must be of considerable extent; and as there will be no chance of preserving the life of the foetus under such circumstances, the expulsion of the ovum is no longer to be avoided, but rather to be promoted; our attention therefore must now be directed to assist the uterus in the evacuation of its contents, with as little injury and danger to the mother as possible. It is, however, no easy matter to decide with certainty when we must give up all hope of preserving the ovum, for a large quantity of blood may be lost without expulsion being a necessary consequence. Uterine contractions may have even taken place, and yet by careful management the mischief may be sometimes averted, and the patient be enabled to go her full time. Even where they have been of sufficient force and duration to dilate the os uteri, we are not justified in discontinuing remedial measures unless the flooding has seriously affected the patient’s strength, and the ovum be actually projecting through the os uteri. “We might often prevent abortion (says Baudelocque) if we were perfectly acquainted with its cause, even when the labour is already begun. A very plethoric woman felt the pains of childbirth towards the seventh month of her pregnancy, and the labour was very far advanced when I was called to her assistance, since the os uteri was then larger than half a crown; two little bleedings restored a calm, so much that the next day the orifice in question was closed again, and the woman went the usual time. Food of easy digestion prudently administered quieted a labour not less advanced in another woman, where it was suspected to be the consequence of a total privation of every species of nourishment for several successive days. Delivery did not take place till two months and a half afterwards, and at the full time. Emollient glysters and a very gentle cathartic procured the same advantage to a third woman, in whom labour pains came on between the sixth and seventh months of pregnancy, after a colic of several days’ continuance, accompanied with diarrhoea and tenesmus.” (Baudelocque,) § 2232. Nor is it always easy to decide whether it be the ovum or not which we feel protruding through the os uteri. “When the abortion is in the second or third month, the practitioner must bear in mind that it may have been retention of the menses, and, therefore, what he feels in the os uteri may either be an ovum or a coagulum of blood. To decide this point he must keep his finger in contact with the substance lying in the os uteri, and wait for the accession of a pain (for where clots come away, pains like those of labour are present,) and ascertain whether the presenting mass becomes tense, advances lower, and increases somewhat in size; this will be the case where it is the ovum pressing through the os uteri. On the other hand, if it be a coagulum, which it is well known assumes a fibrous structure, it will neither become tense nor descend lower, but be rather compressed. Generally speaking, the ovum feels like a soft bladder, and at its lower end is rather round than pointed, whereas, a plug of coagulum feels harder, more solid, and less compressible, and is more or less pointed at its lower end, becoming broader higher up, so that we generally find that the coagulum has taken a complete cast of the uterine cavity. If we try to move the uterus by pressing against this part, it will instantly yield to the pressure of the finger, if it be the ovum; whereas, the extremity of a coagulum under these circumstances is so firmly fixed, that when pressed against by the finger the uterus will move also. When abortion happens at a later period of pregnancy, we shall be able to feel the different parts of the child as the os uteri generally dilates, viz. the feet, or perhaps the sharp edges of bones, although we cannot distinguish the form of the head from the cranial bones being so compressed and strongly overlapping each other.” (Hohl, on Obstetric Exploration.)

Although expulsion must be looked upon as the only means of placing the patient in a state of safety, where the symptoms have advanced so far as to preclude all hopes of preserving the life of the foetus, there are so many steps of this process to be gone through before it can be entirely completed, that more or less time must necessarily be required for that purpose. The ovum must be completely separated from its attachments to the uterus, and the contractions of that organ must have been of sufficient strength and duration to produce such a degree of dilatation of its mouth and neck as to allow the ovum to pass; but before this can be effected, such a quantity of blood may have been lost as greatly to endanger the life of the patient. Hence we must use such means as shall enable us to control the hÆmorrhage, whilst we give the os uteri time to dilate sufficiently: this object will be gained most effectually by plugging the vagina. The best mode of performing this operation is that recommended by Dr. Dewees of Philadelphia: a piece of soft sponge, of sufficient size to fill the vagina without producing uneasiness, must be wrung out of pretty sharp vinegar, and introduced into the passage up to the os uteri; the blood, in filling the cells of the sponge, coagulates rapidly, and forms a firm clot, which completely seals up the vagina without producing any of those unpleasant effects which are produced by the insertion of a napkin rolled up for the purpose. A hard unyielding mass of this nature frequently produces so much tension, pain of back, and irresistible efforts to bear down, as to render it incapable of being borne for any length of time. The sponge plug may be borne for hours without inconvenience; we may either leave it to be expelled with the ovum, or after awhile remove it for the purpose of ascertaining what progress has been made. If the os uteri be still undilated, and the hÆmorrhage going on, the plug must be returned. It is however by no means a remedy to be used in every case of hÆmorrhage, for in most instances the treatment already mentioned will be sufficient to keep it within safe bounds. Where, however, the flooding has become very alarming, and the os uteri still remains firm and but little dilated, the plug will prove an invaluable remedy; and so long as the os uteri remains in this condition, and the uterus itself shows no disposition to contract, we may safely trust to perfect rest, cold applications, and the plug. Opium, which in the early stages of the attack is so useful in keeping off contractions of the uterus, will now for this very reason be contra-indicated; it will diminish the power of the uterus, and interfere with the process of expulsion.

The acetate of lead has been extolled as a powerful remedy for stopping hÆmorrhage, more especially by Dr. Dewees, who states that “in many cases it seems to exert a control over the bleeding vessels as prompt as the ergot of rye does upon the uterine fibre.” (System of Midwifery, § 1045.) We have never tried this remedy in premature expulsion, having found the means of treatment above mentioned sufficient; the authority however of such an author demands respect, the more so as it is known to be a valuable remedy in certain forms of menorrhagia.

Where a considerable quantity of blood has been lost, and the patient is much reduced, we must endeavour not only to excite the contractile power of the uterus, but also to assist this organ in the expulsion of its contents: syncope in these cases is a dangerous symptom, because, as the patient is in the horizontal posture, it will seldom be induced except by a serious loss of blood; although we must not therefore allow her to flood until she faints, still, however, when the pulse has become considerably affected, the os uteri dilates more readily, and in this way facilitates the expulsion; we must no longer trust to the plug, for the whole system is beginning to sympathize and grow irritable, the pulse grows quicker and smaller, and the stomach rejects its contents. Although vomiting as well as syncope are symptoms which we cannot safely wait for, they are nevertheless means which nature adopts to relieve herself from the impending danger: by syncope she not only produces greater dilatability of the os uteri, but also, by causing a temporary cessation of the heart’s action, she favours the coagulation of blood, and thus checks the discharge; whereas, by the involuntary effort of muscles which she excites by the action of vomiting, the ovum is more speedily separated and expelled.

Where it becomes evident that expulsion cannot be prevented, it is our duty to promote this process before nature has had recourse to the means just mentioned. The ergot of rye is here a valuable remedy, for by inducing or increasing the contractions of the uterus we shorten the process and diminish the danger: the powder given in cold water is decidedly the best form in which it can be given; in infusion its powers seem to be injured by the heat of the water, and in tincture by the action of the spirit: the addition of about half its quantity of borax renders its action more powerful and certain. Borax has been long considered in Germany to possess a specific power in exciting uterine contraction, but it was first recommended for that purpose in this country by Dr. Copland. (Dict. Pract. Med. art Abortion.) A scruple or half a drachm of ergot powder with ten grains of borax may be given in cinnamon water, and this repeated every hour for several times.

In all cases threatening premature expulsion, wherever there has been much pain and discharge, the napkins which come from the patient should be carefully examined by her medical attendant, for otherwise the ovum may escape among the coagula and not be perceived. Where the separation is nearly complete, a portion of it protrudes at the os uteri; and this we can sometimes hook down with one or two fingers, and bring away: a still better mode is recommended by Levret, viz. of throwing up a pretty powerful stream of warm water by means of a syringe. Dr. Dewees has recommended a wire crotchet, which he has used with very good effect. (Op. cit. § 1011.)[64] We ought not, however, to be in a hurry to bring away the ovum, for when the uterine contractions have been of sufficient strength to dilate the os uteri, it will generally come away of itself. One objection to the wire crotchet is, that it tears the membranes, and lets out the liquor amnii, and perhaps the embryo.[65] This is by all means to be avoided; the larger the body which is to be expelled, the more powerfully and effectually does the uterus contract upon it: hence, therefore, if the membranes of a three or four months’ ovum be imprudently pierced with a view of hastening the expulsion, the liquor amnii and embryo escape, but the secundines remain and require protracted efforts of the uterus to expel them, during which time the sufferings of the patient are prolonged, and the hÆmorrhage kept up; whereas, if the ovum had remained whole, it would have been expelled more easily and quickly. On the other hand, where the foetus has already attained a considerable size (fifth month,) the plan recommended by Puzos of rupturing the membranes is very desirable; by this means the size of the uterus is reduced by the escape of liquor amnii, and thus the hÆmorrhage checked; and the foetus remaining in the uterus is of sufficient weight and bulk to excite contractions to expel itself and the membranes.

The treatment after abortion varies considerably: in many cases it will be merely necessary for the patient to remain in bed for a few days afterwards; but where she has been much reduced, a mild course of tonics will be necessary, in order to prevent that disposition to leucorrhoea and menstrual derangement which is so common a result: this, where it is possible, should be combined with removal into the country, or to the sea-side, or, what is still better to a watering place, where there are mineral springs of chalybeate character. For the treatment of anÆmia we must refer our readers to the chapter on HÆmorrhage.
