A System of Midwifery Part 12

_Duration of the first stage._ The duration of the first stage of labour varies exceedingly, both in primiparae and those who have had several children; nor is it at all easy to determine with precision the exact moment when labour commences. The sensation of pain to the patient is no guide whatever, for what is attended with much suffering in one patient is scarcely sufficient to excite the notice of another. The dilatation of the os uteri as marking its commencement, must also be taken with some caution: in primiparae, where it generally remains closed until the contractions are becoming painful, it would obviously be wrong to date the commencement of labour from the moment that the os uteri opens, as regular uterine contractions have been evidently present for some hours previously, although not of sufficient force to produce actual pain. On the other hand, in women who have already had several children, the os uteri is found open some days and even weeks before labour comes on. As a general rule, we may state that regular and genuine contractions of the uterus, sufficiently powerful to produce pain, seldom require more than six hours to effect the full dilatation of the os uteri; in many cases a much shorter time will be sufficient; whereas, in others, the first stage of labour may last for more than quadruple this period before it is completed: in neither can it be considered as abnormal; and we usually find that where the pains of the first stage have been slow and lingering, they become remarkably quick and active during the second stage. This agrees with the experience of Dr. Churchill, in his report of the Western Lying-in Hospital at Dublin, viz. that, "no evil consequences resulted, and they (the labours where the first stage was so protracted) were amongst those in whom the remaining stages of labour were shortest."

The first stage terminates with the full dilatation of the os uteri; the rupture of the membranes is a change which is necessarily more or less uncertain, as to the precise period of labour at which it takes place.

Thus, in primiparae, it frequently occurs before the first stage is completed; whereas in other cases the membranes sometimes do not give way until the head approaches or has even pa.s.sed through the os externum; generally speaking, however, they burst at this period of the labour, and usually effect a remarkable change in the whole process. The pains are now of longer duration and more powerful, the intervals between them are shorter, and yet, although the suffering is actually more severe, it is more tolerable to the patient than that of the first stage. During the first stage they are chiefly confined to one spot in the loins; and as they must necessarily continue for some hours without any distinct evidence of the labour being advanced by them, the patient feels discouraged and gets a little impatient at the endurance of so much apparently useless suffering: but as soon as the gush of liquor amnii takes place, she feels that a great alteration has been produced; the abdomen becomes smaller: the pains a.s.sume a very different character, and every thing combines to a.s.sure her that she has made progress, and encourages her to patience and resolution.

_Description of second stage._ The os uteri has now disappeared entirely, so that the v.a.g.i.n.a and uterus form one continuous ca.n.a.l, and is thus admirably adapted for the easy pa.s.sage of the head: the anterior lip, however, dilates much more slowly than the other parts of it, and this is especially the case in primiparae, for, being pressed between the head and pelvis it becomes oedematous, and swells to a considerable size: if the pains be strong, it is pushed down more or less before the head, and may be frequently felt beneath the symphysis pubis, and occasionally it is detruded so far as to be visible between the l.a.b.i.a. According to Wigand, the swelling of the anterior lip sometimes attains such a size as makes it liable to be mistaken for the bladder of the membranes (_op. cit._ vol.

ii. p. 308;) it seldom produces much obstacle to the advance of the head, and with a little patience gradually disappears of itself. All attempts to push it up above the head are objectionable, because, in the first place, the finger cannot reach sufficiently high to effect this object, and therefore the swelling descends again to its former situation; and, secondly, the efforts to push it up only tend to inflame it and increase the swelling. Those who imagine that they can push up the anterior lip of the os uteri above the head deceive themselves; and even if they do succeed, it merely shows that had they let it alone, it would have gone up very shortly of itself.

_Straining pains._ As the head enters the v.a.g.i.n.a, not only do the contractions of the uterus become much more powerful, but now another set of forces are called into action, and the half involuntary efforts of the abdominal and other muscles come to aid the uterus in expelling its contents. The sole object of this stage is the expulsion of the child, and even the v.a.g.i.n.a by its contractions contributes to effect it. The head is therefore subjected to considerable pressure; hence we may now feel the cranial bones overlapping each other at the sutures, and the fontanelles diminished in size; and, from the tightness with which the head is embraced by the v.a.g.i.n.a, the circulation in the scalp is more or less impeded, and a large oedematous swelling, called _caput succedaneum_, forms on that part of the head which presents.

Each pain is attended with a violent and irresistible impulse to bear down, and every muscle which can a.s.sist in effecting this object is now brought into play. The tone of the patient's voice, the expression of her face, the hurried breathing and sudden inspiration, stopping short the moment a pain comes on, in order that she may add still greater power to the efforts which she is about to make, all betoken a very different process to that of the first stage, and one which requires a powerful struggle of muscular strength and energy for its completion. Hence it is that the sound of the patient's voice during the pain is frequently of itself sufficient to inform us how far labour is advanced, for "we never see the really powerful straining pains come on (the head may be never so low in the pelvis,) so long as the os uteri is not fully dilated."

(Wigand, _op. cit._ vol. ii. p. 310.) This is a wise provision of Nature, for by this means it prevents the danger of laceration to which the os uteri would be otherwise exposed, and shows the importance of not permitting a patient to strain and bear down until the os uteri be fully dilated. In those cases where a patient has been induced to exert herself prematurely, the efforts being voluntary are never so powerful, and soon produce much fatigue.

Several reasons have been a.s.signed why the straining pains should come on at this stage. It cannot be owing to the pressure of the head upon the parts of the pelvis, as has been supposed and especially the r.e.c.t.u.m, thus producing the sensation of a violent desire to evacuate the bowels, because, in almost every case of first labour, the head for several days before the actual commencement of labour is sufficiently deep in the pelvis to produce these effects. It evidently arises from a sympathetic connexion "between the os uteri and v.a.g.i.n.a on the one hand, and the abdominal and other muscles on the other. We see this connexion most distinctly in those difficult labours where the head is pushed down deeply in the pelvis even to the very outlet, and where the os uteri which is but little dilated is protruded before it. In such cases we never see the really powerful and continued action of the abdominal muscles excited, let the head press never so forcibly upon the r.e.c.t.u.m; but as soon as the os uteri (perhaps after much suffering) has retracted over the head, the whole auxiliary action of the abdominal muscles commences." (_Ibid._ vol.

ii. p. 467.)

There is the same relation between these muscles and the v.a.g.i.n.a, as there is between them and the r.e.c.t.u.m: the moment the v.a.g.i.n.a becomes distended, it begins to contract upon the distending body, and like the r.e.c.t.u.m excites them to strong and involuntary action. The tenesmus of dysentery is a sympathetic action of the same nature; the r.e.c.t.u.m is highly irritated by the acrid nature of its contents, and excites an irresistible disposition to bear down. The patient wishes for the next pain and yet she dreads it, from the suffering it creates, and the tremendous effort which it compels her to make; the pulse is quicker, and is not only so during the intervals, but undergoes a greater increase of rapidity during the pains themselves than in the first stage; the face becomes red, swollen, and bathed in perspiration; the breath is hurried; the lips are apart; the eyes are wild; every thing betokens a state of the highest excitement.

When a pain comes on, she catches hold of whatever she can reach, plants her feet upon any thing which is firm, and, by thus fixing her extremities, she is enabled to bear down with greater power and effect.

During the struggle the face often changes its expression surprisingly, so much so, that even her own attendants would scarcely recognise her.

_Dilatation of the perineum._ As pain succeeds pain, gradually increasing both in force as well as duration, the head descends along the v.a.g.i.n.a, and begins to press against the perineum; the r.e.c.t.u.m becomes flattened; the sphincter ani dilated, and therefore any faecal matter which may have been lodging there is unavoidably expelled; the anterior wall of the r.e.c.t.u.m is pressed close against the a.n.u.s, and where the pressure is very great, even protrudes somewhat through it; the haemorrhoidal veins are frequently much distended, and form a roll of cus.h.i.+ony swelling around the a.n.u.s. A small quant.i.ty of liquor amnii dribbles away from time to time, but is neither during a pain, nor during the absence of a pain, for in the former case the pressure of the head acts as a plug and prevents its escape, and in the latter there is no uterine contraction present to expel it: the liquor amnii dribbles away only at the moment when a pain is coming on or going off.

_Expulsion of the child._ As the head descends farther it begins to press more powerfully on the perineum, and during each pain pushes it out like a large ball; and then, as a contraction goes off, and the resiliency of the soft parts regain their superiority, it retires again. The breadth of the perineum (viz. from the a.n.u.s to the v.u.l.v.a) increases, whilst it diminishes considerably in thickness, especially towards its anterior margin. Whilst pa.s.sing through the inferior aperture or outlet of the pelvis, the head advances more or less forwards under the pubic arch, and begins to distend the os externum; during a pain it separates the l.a.b.i.a, and protrudes between them, and again retires as the pain goes off; a larger and larger portion of the head gradually forces itself through the os externum as this dilates; the perineum becomes still thinner, so that at length it is scarcely thicker than parchment. When more of the head has pa.s.sed through, it does not now recede when the pain goes off; the os externum and perineum are at their greatest distension, for the largest diameter of the head, which is presented to the os externum is now encircled by it; the next pain brings the head into the world.

This is the moment of greatest pain, and the patient is frequently quite wild and frantic with suffering; it approaches to a species of insanity, and shows itself in the most quiet and gentle dispositions. The laws in Germany have made great allowances for any act of violence committed during these moments of phrenzy, and wisely and mercifully consider that the patient at the time was labouring under a species of temporary insanity. Even the act of child-murder, when satisfactorily proved to have taken place at this moment, is treated with considerable leniency. This state of mind is sometimes manifested in a slighter degree by actions and words so contrary to the general habit and nature of the patient, as to prove that she could not have been under the proper control of her reason at the moment. It is a question how far this state of mind may arise from intense suffering, or how far the circulation of the brain may be affected by the pressure which is exerted upon the abdominal viscera.

A short cessation of pain succeeds the birth of the head. The violent distension of the os externum has ceased for a time, and the patient feels comparatively easy; but in the course of a few minutes the pains return as before, although not quite so severe: first, the shoulder, which is turned forwards, pa.s.ses under the pubic arch, followed by the other which sweeps over the perineum. The rest of the child is expelled with comparative ease, and as soon as its pelvis has pa.s.sed through the os externum, a gush of the remaining liquor amnii, which had been retained in the upper portions of the uterus, follows; the whole abdomen instantly sinks and becomes flaccid, while the uterus contracts into a firm globe upon the placenta, which is shortly to be expelled. A most delightful and perfect calm succeeds, and the sense of freedom from suffering, and joy for the termination of her trial, are expressed in the liveliest terms of grat.i.tude.

_Third stage._--_Expulsion of the placenta._ The period between the birth of the child and expulsion of the placenta varies considerably. Sometimes it follows the child very rapidly, so that, apparently, they are both expelled by the same effort of uterine action; at others, the interval is more considerable. There is generally an interval of ten or fifteen minutes, and then pains of a totally different character make their appearance: these are supposed to denote the separation of the placenta from the uterus, and, from their being usually attended with discharge of more or less blood, have been termed _dolores cruenti_ by many of the foreign writers. The expulsion of the placenta is attended with little or no suffering; it descends into the v.a.g.i.n.a inverted, _i. e._ with its foetal or amniotic surface turned outwards: whether or not this is produced by pulling at the cord is perhaps a question.

_Twins._ If there be twins, the placenta of the first child is seldom expelled until after the birth of the second child. The membranes of the second ovum become distended with liquor amnii, project into the v.a.g.i.n.a and burst as in a common single labour; the pa.s.sages have been sufficiently dilated and prepared by the birth of the first child, so that, when the uterus begins to contract, the expulsion of the second will be readily and easily effected. The uterus may resume its efforts for this purpose in twenty minutes after the birth of the first child, or it may remain quiescent for several hours without at all disturbing the regular and natural course of the process which will be precisely the same as in the previous case.

The placentae of twins are usually expelled together, forming one large placentary ma.s.s; their vessels, however, are distinct from each other, so that with care one placenta can be peeled away from the other. In other cases, they are separated from each other by an intervening s.p.a.ce of membranes; and in one rare instance of triplet placentae the umbilical arteries of two placentae anastomosed with each other, before dividing into smaller branches.

Upon the expulsion of the placenta, the uterus, being now emptied of its contents, contracts into a firm hard ball, which may be felt behind the symphysis p.u.b.es, or sometimes a little to one side, of about the size of a full grown foetal head. This state of hard contraction gradually disappears, and a discharge of blood called lochia follows, which having continued for a few days becomes colourless, and at length ceases altogether. For a description of the changes which the uterus and pa.s.sages undergo in returning to their former condition as in the unimpregnated state, we refer to the chapter on the FEMALE ORGANS OF GENERATION.

This is a subject of great extent as well as importance, because it comprehends the whole ma.s.s of rules for the management of a woman, not only just previous to and during, but also after, her confinement. On nothing does the course of a natural labour depend so much, as upon the careful removal of every source of irritation which may tend in any way to derange or interrupt the regular progress of that series of changes or phenomena which const.i.tutes the great process of normal parturition. It will be necessary that the reader should have made himself thoroughly master of the subjects discussed in the last chapter, before commencing those of the present one. With each change there mentioned, the state of the system and its functions should be carefully watched, and every slight deviation from the natural course of things checked by appropriate dietetic or medical treatment. Hence, therefore, the more a woman can follow her usual avocations, and take that degree of exercise to which she has been accustomed at other times, the better; for by so doing the circulation is equalized, the digestion is kept in full activity, and the tone and general strength of the system maintained.

It would almost seem, by rendering a woman more capable of moving about during the last weeks of pregnancy (which has already been shown to be produced by the sinking of the fundus, enabling the respiration to act more freely,) that Nature intended she should use exercise at this period, and thus prepare her, by increased health and strength, for a process which requires so much suffering and exertion.

Her hours should be regular and early, her meals light and moderate, and by agreeable and cheerful occupation she should fit herself, both in body and mind, to meet the coming trial.

_State of the bowels._ Attention to the state of the bowels is of first importance, and must never be neglected. It is a subject nevertheless upon which women are remarkably careless, and they will frequently, when not attended to, allow labour to come on with their bowels in a very loaded and highly improper condition.

There is, perhaps, no one circ.u.mstance which is found to exert such a prejudicial influence on the course of a natural labour, in so many different ways, as deranged and constipated bowels. Where the contents are of an unhealthy character, the irritation which they produce in the intestinal ca.n.a.l is quickly transmitted to the uterus, and tends not a little to pervert and derange the due and healthy action of this organ: hence arises one of the most fertile sources of spurious pains, a subject which will shortly come under our consideration. Where the bowels are loaded, in consequence of the pressure upon the ascending cava, considerable obstruction to the free return of blood from the pelvic viscera is produced, the vessels of which become considerably engorged. No organ feels these effects more than the uterus: from the immensely dilated condition of its veins, a state of local plethora is engendered, which, from the congested state of the uterine parietes, considerably interferes with the free and regular action of its fibres, and not unfrequently predisposes to haemorrhage.

Moreover, the r.e.c.t.u.m being distended with faeces, diminishes proportionally the capacity of the pelvis, and prevents the ready descent of the head into it; occasionally it forms, at the beginning of labour, a solid cylinder of indurated faeces, so hard, as, at the first touch, almost to induce the suspicion of a projecting sacrum. As a measure of common cleanliness, the bowels ought always to be attended to before labour, for, besides the more serious effects now enumerated, the labour may be rendered exceedingly filthy for the patient, and not less disgusting for the pract.i.tioner; for, as the sphincter ani loses all power of contraction when the head advances deeper into the pelvis, it follows that whatever faecal matter may have been lodging in the r.e.c.t.u.m will now be unconsciously pressed out.

Hence, therefore, for the last few days of pregnancy, the bowels should be regularly opened (unless they are so spontaneously, which is seldom the case) by castor oil or other mild laxatives: and if labour has already commenced before this measure has been taken, and if, therefore, there is not sufficient time for the operation of the medicine, an enema should be given.[66] In Germany it is a rule to throw up some chamomile infusion at the commencement of every labour, by which means the process is rendered more cleanly than is frequently the case in this country; and also, for the reasons already given, the early stage is less apt to be tedious from spurious and ineffective pains.

_Form and size of the uterus._ The more regular the first precursory pains are, the more symmetrical and uniform will be the shape of the uterus; and again, on the other hand, the more uniform its shape, the more regularly and effectively will it act.

It is these slight but early contractions, which, although they produce little or no effect upon the os uteri, exert a very important influence over the first half of labour; for it is by their action, in great measure, that the form of the uterus is determined, as also the correct position of the child. Hence, therefore, some pract.i.tioners lay considerable stress on ascertaining the precise form of the abdomen as a means of determining what sort of labour the patient will have.

In a woman pregnant for the first time, and in a state of perfect health, the uterus is of an oval or rather elliptical form at the beginning of labour: when seen in profile, the abdomen presents nearly a uniform degree of convexity. In this state the child lies with its long axis parallel to that of the uterus, that is, with its head or inferior extremity turned towards the brim of the pelvis; and if the fundus has already sunk in the manner above-mentioned, the pract.i.tioner may very confidently prognosticate that the head presents, even before making an examination per v.a.g.i.n.am.

In a perfectly healthy primipara there is scarcely any inclination of the uterus either to one side or forwards, its median line corresponding with that of the abdomen: whereas, in the multipara, the axis of the uterus is seldom straight, inclining more or less to one side, or, from the greater relaxation of the abdominal parietes, being somewhat pendulous. The size of the uterus should also be taken into consideration, especially in first pregnancies; a large uterus shows that either its parietes are gorged with too much blood, or that its cavity is distended with an unusual quant.i.ty of liquor amnii, or that the child is very large, or that there are twins.

Whatever may be the cause of the distension, it interferes with the regular and effective contractions of the uterus, and tends to make the labour (at least the first part of it) tedious. A moderate sized uterus is much more capable of active exertion, for its fibres not being put so much upon the stretch are enabled to contract better.

_True and false pains._ If the patient is already beginning to suffer pains, it is of great importance to ascertain whether they be genuine or spurious; upon the correct diagnosis of which, the favourable or unfavourable course of the labour not unfrequently in great measure depends.

A genuine labour pain comes on at tolerably regular intervals, rises gradually to a certain degree of intensity, remains at that point for a few seconds, and then subsides as gradually; the body and the fundus of the uterus increase in hardness, and the os uteri in tenseness, in proportion as the pain rises, and vice versa; the pain is seated in the back and loins, and is of a dull aching character: but with the spurious pains it is quite the reverse; they come on and go off suddenly and irregularly, the pain is in the abdomen, and produces a sharp twinging sensation, and the hardness of the uterus and tenseness of its mouth bear no proportion to the pain.

Spurious labour pains are the early contractions of the uterus perverted and rendered irregular, spasmodic, and painful by irritation, congestion, or inflammatory action; they sometimes come on several days before actual labour commences, and if not recognised and removed, may expose the patient to considerable suffering and exhaustion. Derangement of the stomach and bowels is one of the most frequent causes of spurious pains, for by the irritation which is thus produced, the uterus is almost sure to sympathize, and to have its action more or less disordered. This may arise from unhealthy irritating contents of the bowels producing spasmodic, griping, and colicky pains, or from diarrhoea with tenesmus arising from exposure to cold, or from irritation caused by the pressure of the gravid womb. Spurious labour pains of this character also frequently occur in patients who are accustomed to indulge in the luxuries of the table, or in the lower cla.s.ses, who are addicted to the use of spirituous liquors.

Constipation has been already mentioned as a cause of this condition. The state of plethora, congestion, or inflammation, acting as a cause of spurious pains, may arise from various sources: it is frequently observed in strong healthy young women, especially those pregnant for the first time; the pains do not a.s.sume the proper character of genuine labour pains, and exhaust the patient by continued but useless suffering. The os uteri probably dilates somewhat, but its edge remains thin and tense, and the pains appear to have no effect in dilating it any farther. The mucous secretion of the v.a.g.i.n.a is not of the character described at the beginning of labour in the preceding chapter. The pulse is strong and more or less excited, and the flushed face, and generally increased heat of skin indicate the condition upon which those symptoms depend. The inflammatory form of spurious labour pains is not unfrequently of the rheumatic character, a condition which has not been much noticed in this country, but which is capable of exerting a very considerable influence upon the course and progress of the labour. It is usually produced by exposure to cold and the other common causes of rheumatism in other parts of the body, and is generally accompanied with more or less derangement of the stomach and bowels. In this state each contraction of the uterine fibres is attended with much suffering, although the contraction itself may be so slight as to produce little or no effect upon the os uteri. Most of these conditions, in a severe degree, form that species of dystocia which arises from a faulty state of the expelling powers, for the farther consideration of which we must refer to our chapter upon that subject. In a minor degree they produce these slight derangements of uterine action, which we are now considering under the name of _spurious pains_.

_Treatment of spurious pains._ The indications of treatment depend in great measure upon the cause; and we cannot impress it too strongly on the young pract.i.tioner, as a rule never to be lost sight of, that, whatever is wrong in the state of the circulation or of the bowels must be first rectified before having recourse to opiates. Where the stomach is much deranged at the beginning of labour, nature frequently induces spontaneous vomiting, with considerable relief to the patient, and mitigation of the pains; if not a gentle emetic may be administered. Where the bowels are loaded, the treatment already mentioned must be put into practice, after which [Symbol: minim] xx of Liquor Opii Sedativus and of antimonial wine in peppermint water, or gr x of Dover's powder may be given. When there is diarrhoea with a good deal of griping and tenesmus, a dose of castor oil with Liquor Opii Sedativus in any aromatic water may be administered; and if the labour be not yet commenced, gr v of Pil. Hydr. and Dover's powder may be also given at night. If there be a plethoric or even inflammatory condition, the lancet will be of the greatest service; it reduces the temperature of the body, relaxes the soft parts, brings on copious secretion of mucus, and by relieving the congested state of the uterine parietes, enables the fibres to contract with more regularity and effect.

In the rheumatic form, laxatives followed by diaph.o.r.etics, the warm bath, and even venesection will be necessary.

By thus treating the spurious pains according to their cause, they will usually subside readily enough, and be either followed immediately by pains of a more genuine and effective character, or leave the patient perfectly free for several hours, or perhaps even days. It is by inattention to, or ignorance of, these conditions, that patients have been allowed to remain for several days in suffering, during which they have been treated as if they had been in natural labour, until at length they have become so exhausted that, when labour really made its appearance, they were incapable of undergoing the exertions which this process demands.

_Management of the first stage._ The preparatory pains of labour, which form the first stage, do not require that the patient should take to her bed at this early period; and this is especially the case in primiparae, where the first stage is usually somewhat tedious. Until nearly the end of the first stage, she ought rather to be induced to suppose that actual labour has scarcely yet commenced, and that she may still sit up or walk about the room as best suits her feelings, taking care at the same time that every thing is in readiness against the moment when it shall become necessary for her to lie down. A nurse who understands her business will of course duly arrange all these matters, but it behoves the accoucheur, nevertheless, to pay attention to these little details, and to see that every thing is properly prepared: that the bed is ready, and guarded either by several folds of sheeting, or by a leather for the purpose, to prevent the blood and other discharges during labour from soaking into the bedding beneath; this must be done either on the right side or at the foot of the bed, in order that the patient may be better within the reach of the accoucheur: that the patient should be partially undressed, and covered with her dressing-gown: that all the linen should be well aired: that there should be towels, napkins, hot and cold water in readiness, and also a bottle of vinegar, and one of spirit in the room, in case of hemorrhage, suspended animation in the child, &c. &c. These and many other arrangements of less importance are by no means beneath his attention, and require but a moment's glance to a.s.sure him that every thing is properly prepared.

By encouraging the patient to sit up as long as she can, or even to move about occasionally, the pains are rendered more tolerable as well as more effective; the time pa.s.ses more agreeably and quickly; and by the time that it has become necessary for her to lie down, the labour has made so much progress that the rest of its course seems to be much quicker than was at first expected. On the contrary, where the pract.i.tioner at an early period of the first stage, informs her that she must stay up no longer, that she must go to bed and remain lying on her left side, her mind is solely occupied with her pains, which become wearying and irksome; the time pa.s.ses heavily away; she becomes impatient and therefore dispirited; and is much disappointed, that, after remaining in this state for some time, the termination of the labour appears to be as far off as ever.

Nothing eases the pains of the first stage, or increases their effect, so much as frequent change of position and moving about; when, however, they are severe or of long continuance, and the patient becomes fatigued, she will require rest, and this opportunity, afforded by her lying down, should be seized for the purpose of making an examination.

_Examination._ The manner in which this operation should be proposed to the patient cannot be too delicate: it should, as Dr. Dewees has justly observed, always if possible be done by means of a third person, such as the nurse or any elderly female friend who happens to be present. If the accoucheur has proposed it with that degree of gentleness and good feeling which it ought to behove every one to show under such circ.u.mstances, he will rarely, if ever, experience the slightest unwillingness to accede to his request: the better the patient's rank in life is, the more docile will she prove at these times, and the more resolute to undergo whatever she is told it is necessary to submit to. The object of an examination is to determine whether the child presents rightly, whether the labour is far advanced, and to form some degree of prognosis as to its course and duration, &c.: these are points which are of such importance as well as interest to ascertain, that the dread which a patient feels at undergoing an operation so repugnant to her feelings is generally merged more or less in the intense anxiety to know if all is right.

An examination at an early period of labour is important in many respects.

We ascertain the condition of the v.a.g.i.n.a, whether it be soft, cool, relaxed, and well lubricated with mucus, as described at the beginning of the last chapter; whether the os uteri be dilated; whether its edge be thin and tense, or already becoming soft, cus.h.i.+ony, and yielding; whether the membranes are ruptured; whether the presentation be a natural one, and whether the pelvis be rightly formed. In cases where the umbilical cord is prolapsed, it is particularly desirable to ascertain the existence of this displacement as early in labour as possible.

It is usually directed to examine during a pain, because at this moment we feel the os uteri tense, and therefore more distinct to the finger; but it is far better to examine during the interval between the pain: the os uteri being now relaxed, admits the finger more easily; the membranes being loose are not so liable to be ruptured; and, from their not being distended, we shall feel the presenting part more distinctly.

Wherever the os uteri is nearly or fully dilated, or from its condition and the effect which the pains have upon it shows a disposition to dilate with rapidity, the patient should go to bed, as we cannot be sure when the membranes may rupture, more especially in primiparae, in whom this usually takes place early. It is equally desirable, also, in those who have already had children, that the patient should be upon her bed at this moment; because, if the pains be strong, and the os uteri yielding, the head is apt to follow the discharge of the liquor amnii, and sudden expulsion of the child might result at a moment when the patient is unprepared for such an occurrence.

The accoucheur should always examine when the membranes give way, because not only will he be able to feel the presenting part now more distinctly, but if the cord has prolapsed, a coil of it will come down into the v.a.g.i.n.a and cannot escape his notice; in fact, if there is any thing unusual about the presentation, he will be now able to distinguish it with greater certainty. In women who have had large families, the head remains very high in the pelvis until this moment, so that it is frequently extremely difficult to reach it and to ascertain its position: the same is observed with presentations of the nates and of the shoulder, which seldom descend into the pelvis until the liquor amnii escapes.

_Position of the patient during labour._ The position which the patient should take during the actual process of labour has been a subject of considerable discussion, and even at the present day varies exceedingly in different countries. In the earliest periods of history, women appear to have been delivered in a sitting posture, as is described in the first chapter of _Exodus_: this mode was revived in comparatively modern times; thus Ambrose Pare, in 1573, speaks of a labour chair with an inclined back, which he preferred to a common bed. Labour chairs were brought into very general use upon the Continent in the beginning of the last century by Hendrick van Deventer of Dort in Holland, and although they have been in great measure discontinued in modern times, there are still some districts of Germany where they continue to be used. It is a species of chaise percee furnished with straps, cus.h.i.+ons, &c. by which the patient can fix her extremities, and thus enable the abdominal muscles to act with the greatest power. This is the very reason which renders labour chairs objectionable. The presenting part of the child is forced through the soft pa.s.sage with great violence, before they have had time to yield and to dilate sufficiently; hence it has been noticed that lacerations of the perineum are of very frequent occurrence in those countries where labour chairs have been in general use. In some remote parts of Ireland, and also of Germany, the patient sits upon the knees of another person, and this office of subst.i.tute for a labour chair is usually performed by her husband. Labour chairs, as far as we are acquainted with their history, were never used in this country, nor have they been used for the last century in France, where the patients are usually delivered in the supine posture, on a small bed upon the floor, which has not inaptly been termed _lit de misere_. A modification of the labour chair is the labour cus.h.i.+on first used by Nuger, and afterwards by the late Professor von Siebold of Berlin and Professor Carus of Dresden; it is a species of mattress, with a hollow beneath the nates of the patient for receiving the discharges which take place during the labour. The patient is compelled to lie upon her back during the greater part of labour, and thus maintain the same posture for some time, which must necessarily become irksome and even painful to her. In this country and in Germany the patient is delivered upon a common bed, prepared for the purpose as above mentioned: in England she is placed upon her left side, the nates projecting to the edge of the bed, for the greater convenience of the accoucheur: in Germany, except in Vienna and Heidelberg, where the English midwifery has in great measure been introduced by Boer and Naegele, the patient is delivered upon her back.[67] In former times the supine posture was also used in this country, but for about a century the position on the left side has been preferred; the patient lies more comfortably to her own feelings; her face is turned from the pract.i.tioner who sits behind her, and who, from this posture, is able to examine or to perform any other necessary manipulation without her feelings being annoyed by seeing what is going forward. It is decidedly the easiest position during the last moments of tremendous suffering and exertion; when the presenting part is pa.s.sing she is not able to exert an undue degree of violence, and from the knees being kept together, there is less danger of the perineum being torn. The left side seems moreover to be the natural position for a woman at the moment of parturition, for if accidental circ.u.mstances have occurred, such as sudden labour, &c. by which she is deprived of all a.s.sistance at this moment, she will almost invariably be found upon the ground lying on her side supporting herself with one hand. In some cases she will remain during these moments upon her knees, into which posture she has gradually dropped from that of standing: in by far the majority of cases she will take the position upon her side, as above mentioned.
