Lippincott Company y LECTURE 1 ANATOMY. Chapters 2 and 3, Cooke’s “ Handbook of Obstetrics.” 10th edition, (pages 28-42). The pelvis is that portion of the skeleton which lies between the spinal column and the lower extremeties. (page 28). The component parts of the pelvis are : the SACRUM the coccyx, and the two innominate bones each of which is divided into three parts— ILIUM ischium PUBIS The ilium, which is the largest portion of the bone, is broad, thin, con- cave on its inner aspect, and lies above the narrow constricted portion of the pelvis. Joined to the sacrum behind, its upper flaring border forms the promi- nence of the hip or “ crest of the ilium.” (page 28). The ischium, which lies below the ilium, is of obstetric importance from the occasional bony projections which may at times be of sufficient size to obstruct the descent of the foetal head, (page 29). The pubis, by joining its fellow in the front median line, closes anteriorly the cavity of the pelvis. The joint is called the symphysis pubis, (page 29). The sacrum, is a triangular wedge-shaped bone, composed of five welded vertebra, lying at the back of the pelvis to which are joined the two iliac bones. The upper surface supports the spinal column, (page 29). The coccyx, is a small triangular bone attached to the apex of the sacrum, (page 29). regarded as a whole the pelvis may be compared to a basin or funnel, resting on the femurs and supporting the spinal column. As this basin or funnel has no bottom the flaring iliac bones act as a funnel or guide to the bony canal through which the child has to pass at the time of labor. The brim or inlet is the most constricted part of the pelvis and is of obstetric importance for this reason. Any child that can pass safely through the brim can usually be delivered without any further difficulty, (page 29). NURSE’S NOTES The boundaries of the brim are the promotory or upper part of the anter- ior surface of the sacrum, the lower borders of the iliac bones, and the posterior surfaces of the pubic bones, (page 29). The contour of the brim is more or less heart shaped because of the jutting forward of the promotory of the sacrum. The most important measure- ment is the line between the promotory and the symphysis. This is called the conjugate diameter of the inlet, (page 30). The articulations or joints of the pelvis which are of importance are four in number: The two sacro-iliac articulations, posteriorly, the symphysis pubis or articulation between the pubic bones, anteriorly, and the joint between the sacrum and coccyx. These joints loosen slightly during pregnancy and relax somewhat during labor. The pelvis is lined with muscles and other tissues which are called the soft parts of the pelvis, (page 30). COMPARISON OF MALE AND FEMALE PELVIS The female pelvis is shallow, lighter in structure and smoother than the male pelvis, which is deep, conical, rougher for muscular attachment, and more compact, (page 31). PELVIC MEASUREMENTS. The external pelvic measurements are taken with an instrument called a pelvimeter, (page 32). The important measurements are: 1. The intercrf.stal; the distance between the two crests at the widest point. 2. The interspinous ; the distance between the two anterior superior spines of the iliac bones. 3. The external conjugate; the distance between the depression below the last lumbar vertebra and the anterior surface of the symphysis. 4. The external oblique diameters; measured from the posterior superior iliac spines to the anterior superior spines of the opposite sides. 5. The internal conjugate diameter; the distance between the promontory of the sacrum and the posterior surface of the symphysis. 6. The true conjugate diameter is obtained by subtracting an arbitrary figure from the internal conjugate diameter. 7. The Transverse Diameter of the Outlet; the distance between the two tuberosities of the ischium. 8. The Height of the Pelvis; the distance from the tuberosity of the ischium to the crest of the iliac bone of the same side. The importance of these measurements is shown in pelves which are contracted, as a fore-knowledge of the size of the pelvis enables, the obstetrician to tell whether the child will be born normally, or whether an operation as a Cesarean section will be necessary, (page 33). NURSE’S NOTES EXTERNAL GENITALIA, (page 34) The external genital organs grouped as a whole are called the vulva. (page 34). The mons veneris is a firm cushion-like formation lying directly over the symphysis pubis, (page 34). The labia majora are two fatty folds of skin which cover the labia minora and the opening of the vagina, (page 34). The labia minora are two thin folds of mucous membrane which lie entirely within the vulva and form a hood for the clitoris, (page 35). The clitoris is a small reddish tubercle situated about a half inch behind the upper junction of the labia, (page 35). The meatus urinaris is the external opening of the urethra, (page 35). The vagina is a musculo-membranous canal, 5 to 6 inches in length, leading from the vulva to the uterus and lying within the pelvis. Its secretion acts as a natural lubricant. The collapsed mucous lined walls of the vagina take the form of the letter H. (page 35). INTERNAL ORGANS OF GENERATION, (page 35) The uterus is a hollow, pear-shaped organ about three inches long in the non-pregnant state. The walls are composed of involuntary muscle fibres arranged in whorls and it is lined with a specialized type of glandular secreting cells, called the endometrium. It is covered almost wholly by the peritoneum, (pages 35-36). The ligaments which support the uterus and maintain its position in the pelvis are two broad ligaments running from the uterus to the side walls of the pelvis, composed of folds of peritoneum, carrying blood ves- sels, and supporting at the top the Fallopian tubes; the round ligaments which run from the fundus or top of the uterus to the anterior abdominal wall; the uterosacral ligaments which run from the cervical portion of the uterus to the posterior wall of the pelvis, (page 36). The fundus is the upper part of the uterus, which expands and enlarges during pregnancy. It comprises two-thirds of the uterus in the non-pregnant state, (page 38). The cervix is the neck of the uterus. It is the lower narrow third which projects into the vagina, like a cork into a bottle, (page 38). The fornices are the spaces between the projecting cervix and the vaginal walls. The posterior space or fornix is much deeper than the anterior on account of the position of the uterus in its relation to the axis of the vagina, (page 38). NURSE’S NOTES The cavity of the uterus is divided into two parts, the cavity of the fundus, which is triangular in shape, with the apex pointing downward, and the cavity of the cervix, which is spindle shaped, (pages 38-39). The three openings of the uterus are the two at the upper outer angles of the body or fundus where the tubes enter the uterus, and the lower end of the cervix which is called the os; the upper end of the cervical canal is spoken of as the internal os. (page 39). The fallopian tubes are two tubes running outward from the uterus for four or five inches to a trumpet-shaped ending, called the fimbriated extrem- ity, from its fringe-like terminations, (page 39). The ovaries are two almond shaped organs attached to the posterior sur- faces of the broad ligaments between the uterus and the ends of the Fallopian tubes. In them are the original germ cells, which mature about the time of each menstrual period, and if not impregnated by a male element, the usual phenomena of menstruation occur, (page 39). The perineum is the mass of fibrous and muscular tissue lying between the vagina and the anus. It is formed by the junction of the muscles of the pelvic floor and the fascia around them. When the perineum is overstretched during labor varying degrees of laceration result, (pages 39-40). The breasts are two highly developed glands on the upper anterior sur- faces of the chest. They are made up of lobes or collections of glandular and fatty tissue. The ducts from the different lobes empty in a conical projection at the centre of the breast, called the nipple. Around the nipple is an area of darker skin called the areola, which becomes much darker during preg- nancy. After labor certain stimuli reaching the breasts cause them to secrete milk. During pregnancy the congestion of the breasts is accompanied by the secretion of a clear fluid called colostrum, (pages 40-41-42).

NURSE’S NOTES LECTURE 2 PHYSIOLOGY OF REPRODUCTION. Chapters 4 and 5, Cooke’s “Handbook of Obstetrics10th edition, (pages 43-66). DEVELOPMENT OF GRAAFIAN FOLLICLE. At birth the ovary contains about 70,000 ova or germ cells, entirely un- developed. About the age of 13 and once a month one of these germ cells enlarges and approaches the surface of the ovary. This enlarged ovum lying beneath the surface of the ovary is called the Graafian follicle. It ruptures at a thin place on its wall and the ripened ovum escapes, (page 43). OVULATION. The process by which the ovum ripens and escapes is called ovulation. It is usually accompanied by menstruation except during lactation. Ovulation can take place without menstruation, (page 44). puberty in females is the time of life at which menstruation is first estab- lished. It usually occurs about 13 years of age. (page 45). adolescence is the period between puberty and maturity, when the physi- cal characters of womanhood are being established, (page 45). menstruation is the name given to the periodic discharge of a bloody fluid from the uterus. It occurs normally at regular intervals of 28 to 30 days except during pregnancy and lactation. Some women have a normal 21 day period. The flow lasts as a rule from 3 to 5 days and the amount is gauged by the number of napkins necessary. It is accompanied in most cases by a feeling of fullness in the pelvis, slight headache and some tingling in the breast, (pages 45-46). amenorrhea is a term signifying absence of menstruation. menopause or change of life occurs at about 45 years of age. It signifies the end of the active reproductive life of the individual. It is often characterized by the menses becoming scant and irregular before ceasing, (page 47). impregnation of the ovum or fertilization is the meeting and entrance of a male element into ovum; this usually takes place in the Fallopian tube, (page 48). NURSE’S NOTES segmentation of ovum. After fertilization of the ovum by the spermato- zoon, the ovum begins to develop by dividing many times so that each cell possesses half male and half female matter. This continues to the develop- ment of the fetus and its coverings. While the process is going on the ovum passes from the Fallopian tube to the uterus. (page 49). decidua. In preparation for the fertilized ovum the mucous membrane of the uterus has changed into a spongy layer which is called the decidua. If the ovum has not been fertilized this developed membrane is cast off in the menstrual flow, (pages 49-51). But if pregnancy has begun this spongy layer of tissue forms a place for the ovum to rest as it comes from the tube to the uterus. The decidua, while one membrane at first, is spoken of as three kinds. The decidua serotina upon which the ovum rests after it lodges in the uterus, and which later helps to form the placenta, (page 50). The decidua reflexa, which folds over the ovum enclosing it in a capsule, as it were, and (page 50). The decidua vera, which lines the remainder of the uterine cavity, (page 50). The chorion, which is the middle layer of the amniotic sac, has for its special purpose the burrowing into the walls of the uterus by means of small projections to furnish the food supply of the ovum, until the formation of the placenta, (pages 52-53). The placenta is formed by the decidua serotina and the chorion which covers the decidua serotina. At term the placenta is a fleshy mass about seven inches in diameter, an inch or so thick, round in shape and weighing about a pound. It is smooth on the foetal side, being covered with amnion and rough on the maternal side, the rough projections in clumps being called cotyledons; to it is attached the umbilical cord, (page 53). The amnion is formed by the blending of the decidua and the chorion around the ovum, it is soon a clear membrane which secretes the fluid in which the fetus lives. The amniotic sac protects the fetus from injury, allows it freedom of motion, and at the time of labor acts as a hydrostatic dilator for the cervix, (page 52). The liquor am nii which fills the sac is a clear straw colored fluid in which the fetus floats, (page 51). The umbilical cord attaches the fetus to the placenta, and carries the blood which gives the fetus its oxygen and nourishment. The placenta and umbilical cord form at about the fourth month. The cord at term is about NURSE’S NOTES 20 inches long. It is composed of two arteries and a vein, twisted upon each other and protected by a soft gelatinous substance called the Jelly of Wharton, (pages 53-54)- ovum at 4 weeks. At the end of four weeks the ovum is merely a small spongy looking sphere containing a small curved gelatinous mass, with no evidence of head or extremities, and if abortion occurs at this time is is usually lost in the discharge of blood, (page 55). ovum at third month. At the end of the third month the ovum is about four inches in length and weighs about three and a half ounces. The now developed head occupies a third of the entire fetus. The neck and extremities are formed and sex can be told. The skin is a pale rose color, very delicate. The placenta is just formed, (page 55). ovum at sixth month. The fetus is now about 12 inches long and weighs about a pound. Faint evidences of the eyelashes and eye brows have appeared and the skin is darker and firmer, (pages 55-58). ovum at seventh month. Development is very rapid during the seventh month. The fetus is 15 inches long and weighs 3 to 4 pounds. The eyelids can be opened and the skin is much firmer, lighter, and is covered with a cheesy, greesy material called vernix caseosa. This is the earliest time at which a child can be born with any prospects of living. The term viability refers to the possibility of the child living, (page 58). ovum at term. The fetus at term is from 18 to 22 inches long, weighs 6 to 7 pounds, and is ready to assume the functions of respiration, digestion and excretion, (page 58). The head of the fetus is still the largest part of its body, although it has not increased in size proportionately with the other parts during the latter part of the pregnancy. It is divided into two parts, cranium and face, (page 58). The sutures are the membranous intervals separating the different bones of the cranium, and permit overlapping of the bones during delivery, (page 58). The fontanelles are the intersections of the sutures and from the posi- tion of the various fontanelles the position of the head during labor is deter- mined. The moulding of the baby’s head is due to the squeezing of the bones and their overlapping during labor, (page 60). foetal circulation. The fetus receives its food and oxygen from the mother by means of the placenta and cord and by them returns its waste products for excretion. The cord has two arteries and one vein. The fresh blood comes to the child through the vein and the returning blood is carried by the arteries. The difference in the foetal circulation and that after birth may be understood NURSE’S NOTES when we realize that the lungs and digestive tract of the fetus do not function and there is no need for the pulmonary circulation nor for so great a blood supply to the intestinal canal. So there are certain structures in the foetal cir- culation which act as switches to keep the blood from certain parts of the body and which immediately after birth are of no further service and are at once abandoned. The most important of these is the foramen ovale, which permits the blood to pass from the right auricle to the left auricle, thus keeping it from the lungs, but immediately after birth, as the infant must oxygenate its own blood, this valve must be kept closed by nature and by keeping the infant on its right side to favor the closure of the valve. The others are the ductus arteriosus, connecting the aorta and the pulmonary artery; the ductus venosus, connecting the umbilical vein, and the ascending vena cava; and the two hypo- gastric arteries; springing from the internal iliacs and passing out of the abdo- men through the navel, into the cord where they become the umbilical arteries, (pages 60-64). This course of the foetal blood and of the infant immediately after birth, in contrast to the foetal circulation, can be best seen in the charts, pages 62 and 63, Cooke’s “ Handbook of Obstetrics.” multiple gestation. When as occasionally happens, two or more em- bryos develop in the uterus at the same time the condition is known as multiple gestation. Twins are encountered once in 90 cases, triplets once in 8,000. (page 65). twins are due to the fertilization of two separate ova, either from the same or from different Graafian follicles but they may result from the double inpreg- nation of a single ovum by two spermatozoa or from the complete fusion of a single germ, (page 65). The most frequent combination of sex is a boy and a girl, next is two boys, and least common is two girls. triplets, etc. Triplets come from the double inpregnation or com- plete fusion of one ovum and the simultaneous fertilization of another single ovum, while quadruplets may be regarded as double twins, (page 66). In the case of multiple births the umbilical cord must always be cut between ligatures to prevent the second child from bleeding to death. Children born of multiple pregnancies are usually more frail than in single births and more care must be exercised in their early infancy, (page 66).

Chapter 6, Cooke’s “Handbook of Obstetrics.” 10th edition. (pages 67-74). LOCAL CHANGES. The uterus increases in size to make room for the growing fetus. It becomes more vascular and thickened, later thinning out, the mucous membrane becomes the decidua of pregnancy. The uterus rises out of the pelvis at four months, (page 67). The abdomen distends to accomodate the enlarging uterus. The stretch- ing of the skin causes red or blue streaks which are called the “ linea albicantes or stria gravidarum,” and are due to the stretching rupture and atrophy of the deeper layers of the skin, (page 67). The pelvis does not change except for a slight increase in the mobility of the various joints. The vagina becomes thickened, as to its wall, the secretion is greatly in- creased, and due to the increased vascularity the walls are of a dark blue color which in contrast to the usual pink color of the non pregnant state is a diagnos- tic sign of pregnancy, (page 69). The breasts change to prepare for the work of secreting milk. They become larger and firmer, and the nipples become more prominent and sensitive. The pinkish areola about the nipple becomes darker in color to a brownish or almost black. The small sebaceous glads about the nipple become enlarged to little elevations called the “tubercles of Montgomery.” (page 69). The distension of the breasts cause similar stria on the skin as are seen on the abdominal wall. After the third month the breasts contain a thin white fluid called the colostrum. Milk is not secreted until after the baby has been born. The blood increases in amount and in its fluid constituents but the red cells are not proportionately increased. This causes extra work on the heart and may also cause a slight swelling of the ankles, not to be confused with the swelling of the kidney disorders, (page 70). The lungs are subject to pressure in the later months of pregnancy from the growing uterus and the patient may suffer from cough and dyspnea, (page 70). NURSE’S NOTES The digestive tract is subject to increased demands to provide for the mother and child, and nausea and vomiting are a sign of early pregnancy while gastric symptoms and constipation are the rule in the later months from the pressure of the growing uterus, (page 70). The nervous system of a pregnant woman is easily subjected to any dis- turbing influence. The urine of a pregnant woman is increased in amount and is usually of a low specific gravity. Irritability of the bladder is frequent in early and late pregnancy from pressure. Traces of albumin are often found which are of no moment, but it may be progressive and due to serious kidney changes and this necessitates a careful examination of the urine at stated intervals through the whole pregnancy, (page 73). SIGNS AND SYMPTOMS OF PREGNANCY. Chapter 10, Cooke's “Handbook of Obstetrics.” 10th edition, (pages 84-90). PRESUMPTIVE SIGNS. menstrural suppression—amenorrhea. Amenorrhea or cessation of menstruation due to impregnation is usually the first symptom noticed by the patient, (page 85). irritability of the blauder, occurs after three or four weeks and con- tinues for about six weeks and is due to the sinking and pressure of the recently impregnated uterus, (page 85). nausea and vomiting, occurs after about six weeks and usually con- tinues for about six or eight weeks and is supposed' to be due to the effect of the reaction of the woman to the pregnancy, (page 86). mental symptoms. Mental symptoms may be various and range from altered appetite to marked changes in the mental condition of the patient, (page 86). PROBABLE SIGNS. mammary changes include enlargement, slight pains, sense of fullness, darkening of the areola and erectile nipples, later on the secretion of colostrum. Breast changes are not so marked in repeated pregnancies, (page 87). PHYSICAL SIGNS ON EXAMINATION. abdominal changes. No abdominal changes are seen during the first three months. Pigmentation of the median line “ linea Nigra ” occurs about five months. The uterus may be felt in the abdomen as early as the fourth month, (page 88). NURSE’S NOTES The vaginal mucosa becomes thicker, blue in color. The secretion may be noticed to be increased, (page 89). The uterine murmur due to the increased vascularity may at times be found. intermittent uterus contractions of a rhythmical nature may often be noticed on prolonged inspection of the abdomen during pregnancy. POSITIVE SIGNS. passive foetal movements may be elicited by the physician on examina- tion, as the head when pushed up quickly by a finger in the vagina will quickly drop back; this is called “ ballottement.” (page 89). active foetal movements may be seen and felt after the fifth month by placing a hand on the abdomen. The first sensation of the mother of these movements is called “ feeling life,” and is usually first noticed about the 22nd week of pregnancy, (page 90). the foetal heart sounds may be heard about the fifth month, and are compared to the ticking of a watch under a pillow; the rate is about 150 per minute, but varies, (page 90). MANAGEMENT OF PREGNANCY Chapter 11, Cooke’s “ Handbook of Obstetrics(pages 99-117). The clothing of a pregnant woman should be governed by common sense. It should not in any way interfere with the free development of the fetus, (page 99). supports are a great help to many pregnant women. Various types of maternity corsets and belts are sold. A comfortable front lacing corset will usually supply the necessary support, (pages 99-100). shoes with low heels will relieve much of the leg strain and backache felt by many women during pregnancy, (page 102). exercise is necessary during pregnancy, it should be limited and never be carried to the point of fatigue. Walking is the best form of exercise, (pages 102-103). bathing assists in the elimination of the waste products, mild tepid baths just before retiring are preferable. Shower baths are preferable to tub baths in preventing any entrance of water into the vagina, (pages 104-105). sleep in greater amount than usual is required and in addition a daily sleep of an hour or two will be found beneficial, (page 105). NURSE’S NOTES The teeth of a pregnant woman have a tendency to softening due to the increase of saliva and to the abstraction of calicum salts by the growing fetus. During pregnancy rigid mouth hygiene is necessary. Dental work should be limited, but performed when necessary, (page 105). The diet of a pregnant woman should be a simple ordinary mixed diet. No extra strain should be thrown on the organs of elimination. Meat should be allowed but once a day. An increased amount of water is necessary, (pages 106-107). bowels. Constipation is the rule in pregnancy. It may be overcome by fruit, etc., in the diet, or by the use of mild laxatives. Drastic purgatives should be avoided, (pages 108-109). blood pressure. Estimations are as necessary as urine examinations in the prevention of toxemias and should be made at regular and frequent intervals. kidneys. No organ requires more watching than the kidney. The amount of urine passed should be measured at regular intervals, it should never be allowed to drop below two pints a day. The examinations of the urine will detect any changes in the functional ability of the kidney to excrete the waste products of the mother and fetus. The patient should be instructed to report promptly any symptom of kidney insufficiency, (pages 109-110). breasts. The breasts need no especial care beyond careful bathing unless there is a lack of development of the nipples, when a little massage late in pregnancy will assist in developing them, (pages iio-m). nervous condition. Any anxieties of a pregnant woman should be avoided. She should be protected from irritating or worrying conditions and circumstances, (pages 111-113).

NURSE’S NOTES LECTURE 4 PATHOLOGY OF PREGNANCY. Chapter 16, Cooke’s “Handbook of Obstetrics.” 10th edition, (pages 183-213) nausea and vomiting, are present in almost all pregnancies to a greater or less degree, and may be considered if mild as a physiological process. The mild form is termed the (page 183). reflex type and is, as a rule, amenable to treatment. This should con- sist of breakfast in bed, coffee or tea and toast as examples of the proper diet for this meal, and the milder sedatives as sodium bromid. The condition appears after the first month and usually disappears in a few weeks. But at times the vomiting becomes more pronounced, occurs during the entire day and causes marked prostration and weakness, resisting all forms of treatment and this degree of vomiting is termed the (page 183). pernicious type. Under such circumstances the patient is kept in bed, and feeding may at times be administered by the rectal tube. Various enemas may be used. A solution of glucose will more easily supply the necessary heat units needed. Many remedies have been used in this condition, among them the various ovarian substances, reasoning that a deficiency of the internal secre- tion of the corpus luteum is responsible for the condition. Should all treat- ment fail and the patient’s condition becomes serious the induction of abortion may be rendered advisable, (pages 184-185-186-187). constipation, which is common during pregnancy is due largely to the impaired peristaltic motion of the intestine caused by pressure from the gravid uterus. The dangers of persistent constipation during pregnancy are evident. The condition should be overcome by altering the diet, exercise and by such drugs as cascara, mineral oil, or mild aperient waters, (page 187). diarrhea occurs occasionally during pregnancy and if allowed to persist may result in miscarriage. Castor oil should not be given to a pregnant woman, but the bowel should be cleared by saline enemas and bismuth given to check the diarrhea, (page 188). varicose veins in pregnancy are seen in the legs and on the vulva and may even extend into the pelvis itself. The swelling and enlargement is due to the weakness of the walls of the veins and is accentuated by the pressure from the gravid uterus. The condition gives rise to a dull aching pain and is recognized on examination. Elastic bandages or stockings and resting in NURSE’S NOTES the recumbent posture will give some relief. Thromboses should be guarded against during the puerperium. (pages 189-190-191). edema, if not from kidney or heart disease is due to pressure on the blood vessels and may be relieved by rest and proper corseting. Edema developing in a pregnant woman should occasion an immediate urine examina- tion. (page 191). cardiac conditions are often greatly aggravated by pregnancy and labor. Rest and careful attention to all the rules of the hygiene of pregnancy will often carry a woman to term when either an early forceps delivery or a Cesar- ean section will relieve the weakened heart muscle. Severe cases of heart dis- ease with poor compensation may be indication for therapeutic abortion or premature labor, (page 192). leucorrhea occurs frequently during pregancy and is due at times to an increase in the vaginal secretion; at other times to increase from congestion of an old cervical disease. Local treatment, preferably mild douches, should be used with care to prevent abortion or miscarriage, (page 194). eclampsia is a disease of pregnancy characterized by the occurence of convulsions resembling somewhat those of epilepsy, and appearing, usually, late in pregnancy just at the onset of labor, (pages 196-197). The cause of eclampsia is unknown, but is believed to depend upon the deficient elimination of waste products. Its threatened onset is indicated by the appearance of albumin in the urine and a rising blood pressure, (page 197). The premonitory symptoms are albumin in the urine, headache, nausea, pain in the epigastric region, dizziness, constipation, edema, and failure of vis- ion. (page 198). The prophylatic treatment of eclampsia consists in the application of the rules for the proper management of pregnancy, (page 198). The preventive treatment of the convulsions after the premonitory symptoms have appeared are to put the patient to bed and favor elimination. And the cardinal principles of this treatment are mild diet, forcing the fluid intake, free opening of the bowels with saline laxatives, favoring perspiration with hot baths or hot packs, and increasing the elimination of urine with the various diuretics, (pages 201-202). symptoms. The attacks are very much alike. The patient after com- plaining of dizziness or headache has a sudden convulsive stiffening and rigidity of certain muscles which twist the body and face, causing a horrifying appear- ance and cyanosis; this is soon followed, in a few seconds, by a violent muscular twitching, after which the patient may remain in a state of coma or partial coma for some time. The patient may die during an attack. Injury to the tongue is frequent in these attacks, (page 199). NURSE’S NOTES diagnosis. The convulsions of epilepsy and hysteria may be confused with those of eclampsia, (page 200). treatment. Upon the appearance of eclamptic convulsions, after send- ing for a physician, the nurse should put the patient to bed. A mouth gag should be at hand to protect the tongue from injury. The clothing should be removed, an enema given, and a hot pack started. Further procedures will be ordered by the physician and will consist in washing out the stomach, with the introduction of castor oil and croton oil, or magnesium sulphate to promote free purgation. The lowering of the blood pressure by venesection, and such obstetric measures as are considered necessary may then be performed. As a rule, unless the patient is well advanced in labor most physicians continue the eliminative measures for a time. In emergency cases with no means at hand with which to work, restraint of the patient and the prevention of injury to the tongue during convulsions should be remembered, (pages 201-202- 203-204). When eclampsia occurs during labor, early delivery, by forceps, is often indicated, or such simple means as rupturing the membranes may be done to hasten labor. An eclamptic should not nurse her baby until after the first secretion of milk in the breasts has been thoroughly removed with the breast pump. after care. After an attack of eclampsia the patient should be treated for such a period of time as is necessary for the relief of the injury to the kidneys and liver. An attack of eclampsia is often the starting point of a mild persistent kidney disease, (page 244). Chapter 18, Cooke’s “ Handbook of Obstetrics(page 244) abortion, signifies the expulsion of the fetus or ovum before the third month. Various terms are used to describe various kinds of abortion: threatened : When there are symptoms of abortion present. inevitable: When there is no chance of saving the pregnancy. incomplete : When part of the ovum has been expelled. complete : When the entire ovum has been expelled. therapeutic : When the abortion is done to save the mother’s life. criminal or illegal: When it is unlawfully performed to destroy the pregnancy. septic : When the abortion is complicated by fever. abortion may be caused by disease of the mother as typhoid fever, or of the uterus, locally, as endometritis, inflammation of the lining membrane of the uterus, or of the ovum, when it is unable to properly imbed itself in the uterus, (page 244). NURSE’S NOTES The symptoms are bleeding and pain, of varying degree. Discharge of part or the whole of the ovum is determined by the nature of the discharged particles, and all blood clots should be saved for examination by the physician, (page 245). treatment. Treatment of threatened abortion is rest and sedatives. Of most other varieties the treatment is currettage. (page 246). miscarriage (page 246) is technically the expulsion of the ovum or fetus from the third to the seventh month. The uterus usually expels the fetus but there is often a retention of the whole or a part of the placenta necessitating operative removal. While after abortion and miscarriage the treatment is the same as after labor, as regards cleanliness and stay in bed, yet after miscarriage attention should be paid to the breasts which will often functionate for a few days. premature labor (page 252) signifies the expulsion of the fetus from the seventh month to term. It is simply labor in miniature. Again the chief danger is retention of the placenta, and also improper involution of the uterus. The nervous shock associated with many cases of premature labor should be born in mind. The chief nursing care in premature labor is the baby. This subject will be discussed in a subsequent lecture. placenta previa (page 204) is the name given to the condition when the placenta is situated in an abnormal position, chiefly at or near the internal os, the inner opening of the cervical canal. The cause is a low implantation of the ovum due to an old endometritis. The symptom is painless bleeding at any time during pregnancy, but most often seen at the onset of labor when the dilating cervix pulls loose a part of the placenta. The placenta previa is termed lateral, partial or central, depending on its relation to the internal os. The treatment is absolute quiet until seen and examined by a physician. The operative treatment depends upon the situation of the placenta and may range from simple rupture of the membranes to forceps delivery, packing with gauze, insertion of bags, version, or Cesarean section. premature separating of placenta (page 209) is usually the result of some form of trauma, fall or blow, but some cases may result from very simple jars, and others are believed to be due to pathological conditions of the uterine wall or placenta itself. The symptoms are painful hemorrhage or intense abdominal pain when the blood does not escape from the uterus and symptoms of hemorrhage. The treatment is absolute quiet until seen by a physician. The operative treatment depends upon the severity of the case. When the condition develops during labor it must be distinguished from rupture of the uterus. NURSE’S NOTES ECTOPIC GESTATION Or EXTRAUTERINE PREGNANCY (page 206) is the development of the fertilized ovum before it reaches the uterus, most often in the tube. Here it develops until the tube is so stretched that the ovum can no longer be contained and it is either extruded from the end of the tube, tubal abortion, or the wall of the tube ruptures, tubal rupture. The symptoms of either of these conditions would be amenorrhea, with other symptoms of early pregnancy, then an attack of sudden abdominal pain and symptoms of internal hemorrhage. The treatment is operative and consists in the removal of the tube and ovum. Quiz questions for this lecture will be found in Foote’s “ State Board Questions and Answers for Nurses.” J. B.

Chapter 7, Cooke’s ‘‘ Handbook of Obstetrics.” 10th edition, (pages 75-80) labor, is the expulsion of the full term ovum from the uterus. It is also known by the various names of “ delivery,” “ confinement,” “ lying-in ” and “parturition.” (page 75). The usual term for labor to take place is 280 days after conception, (page 75). variations occur in or under certain circumstances, and prolonged preg- nancy may have a legal significance. Thus in France a child is considered legitimate if it is born as late as 300 days after the death of the father. Prema- ture labors may occur from a few days to a few weeks ahead of the date calcu- lated. (pages 75-76). the cause of labor is probably the reaction of the over-stretched muscu- lar fibres of the uterus at term. This is very likely as is shown when in twins or in case of excessive amount of amniotic fluid labor often begins when the uterus reaches the size of a full term normal pregnancy, (page 76). the premonitory symptoms of labor are well marked in the first pregnan- cies. They are usually due to the sinking down of the uterus into the pelvis preparatory to the engagement of the head. Thus the embarrassment of heart action and lung expansion will be relieved. The abdomen appears more pro- tuberant, and pressure symptoms are more marked. There is bladder irritability, cramps in the legs, more marked constipation, but on the whole, the woman feels more comfortable, (page 76). stages of labor. Labor may be divided into three stages, (pages 76-77). first stage from the onset of labor to the full dilatation or opening of the cervix. second stage from the full opening of the cervix to the expulsion of the child. third stage from the end of the second stage to the expulsion of the placenta and the contraction and retraction of the uterus. labor pains are merely muscular contractions of the uterus, and are called “ pains ” because of the suffering which accompanies them, (page 77). NURSE’S NOTES phenomena of the first stage. During the first stage the contractions are weak and infrequent. The patient is able to be up and about. As time goes on the contractions become more frequent. The bowels and bladder are emptied frequently. The pains gradually become more frequent and severe. The patient complains of the slow progress. Nausea and vomiting may be present. As the pains increase the cervix opens and the end of the first stage is often marked by the rupture of the bag of waters, the amniotic sac. (pages 77-78). phenomena of the second stage. The contractions are now so pain- ful that the patient of her own accord goes to bed. The pains are frequent, coming every 2 or 3 minutes, and are marked by a desire on the part of the patient to bear down; there is a red suffusion of the face and neck during the pains. The patient mumbles and cries out at the acme of the contractions. As the head presses down in the pelvis small particles of fecal material are expressed from the anus, and urine is often expressed. Finally, as the pains increase in severity, the head appears and is born at the acme of a contraction ; following the birth of the child the mother gasps for breath and rests, (page 78). phenomena of the third stage. After expulsion of the child the uterus shortly again begins its rhythmical contractions, these serve to loosen the placenta and expell it from the cavity of the uterus into the lower uterine segment or vagina, and thence through the vulva with the membranes trailing behind it. (page 79). total duration of labor. The total duration of labor in normal cases averages 10 hours, the greater part of which time is taken up in the first stage; but the time may vary from 2 to 24 hours without being in any way abnormal or injurious to the patient, (page 79). THE MECHANISM OF LABOR. Chapter 10, Cooke’s “Handbook of Obstetrics.” (pages 91-99). the three important factors to be considered in the expulsion of the full term fetus are, (ist) the passenger, the fetus, (2nd) the passages, the uterus, vagina and vulva, and (3rd) the forces of labor which expell the fetus along the birth canal, (page 91). the forces of labor may be considered as 2 classes, the expulsive forces, the uterine and abdominal muscles, and the resistant forces, the muscles of the pelvic floor, the tissues of the cervix and the vagina. For labor to terminate naturally the expulsive efforts must be greater than the resistant elements. This slight overbalance prevents prolonged labors on the one hand and too quick a labor on the other hand, (page 91). NURSE’S NOTES presentation refers to the part of the fetus which “ presents ” in the brim of the pelvis at the beginning of labor. Thus if the head lies in the brim ready to come into the vagina it is called a “ vertex ” presentation, while if the buttocks present it is called a “ breech.” (page 91). position has to do with the relation of the presenting part to the pelvis. Thus in a vertex the position is named from the way the back of the head, the occiput, lies in relation to the mother’s pelvis. If in front and on the left it is said to be in the left occiput anterior position, and so on. (pages 91-92). l. o. a. Occiput to front and left. r. o. p. Occiput to right and back. vertex presentations occur in about 97 per cent, of all cases, probably because the head is the heaviest part of the fetus and so has a natural tendency to sink to the bottom of the uterus. The position of the vertex presentations is L. O. A. in over 70 per cent, of all cases, (page 92). flexion. In order that the vertex, or top of the head may present, the head must be tipped over on the chest or flexed, and this flexion increases as labor progresses until the head has passed through the brim of the pelvis and is in the vagina, (page 92). rotation. While the head is thus flexing in descending it meets with the resistance of the inclined walls of the pelvis and this resistance causes the present- ing part to rotate forward until the occiput or back of the head lies just behind the symphysis or pubic joint. extension. As soon as the completely flexed head has passed through the pelvic brim and lies with the occiput under the symphysis the process of extension begins. The chin is now raised by the expulsive forces from the baby’s chest and is raised over the pelvic floor and perineum until the chin is born, when the occiput which has been acting as a pivot for this movement is also born and then the head rotates back to its original position to regain its original relation to the unborn shoulders. This is called— external rotation or restitution. After this movement the body of the child is usually born by further expulsive effort on the part of the mother, (pages 92-93). face presentation, occurs when the head is extended or tipped back on the body of the child. It usually demands operative interference, (page 94). brow presentations are those midway between face and vertex, and occur when the head is neither fully flexed or extended. They usually become con- verted into vertex presentations by further flexion as labor proceeds, (page 9s). NURSE’S NOTES breech presentations are those in which the breech instead of the vertex presents at the pelvic brim. They are fairly common, the chief danger being that as labor advances the arms are liable to become extended above the head of the fetus and interfere with its passage through the pelvis. The discharge of meconium is a sign of a breech presentation, as during labor the child’s body is squeezed so firmly that the meconium is pressed out and passes down the birth canal, (pages 95-96). l. sc. a., or left sacrum anterior, signifies that the breech is presenting and the position of the sacrum is on the left side and anterior; this corresponds to the naming of the vertex positions, (page 96). transverse position, or cross positions are usually found in women who have born many children, or where some deformity or tumor complicates preg- nancy, or one of twins may be in the transverse position. The child may be in a tranverse presentation with arm, hand, shoulder or back as the part lying directly over the cervix. Such cases are treated by version as a rule, (page 97). OBSTETRICAL DIAGNOSIS. inspection of the abdomen gives little information other than perceiving foetal movements and uterine contractions and the general size of the pregnancy. palpation reveals the position of the fetus; the palpation should be gentle, and carried out by placing the flat hands upon the abdomen so as not to provoke a uterine contraction. The fundus, the lower part of the uterus and the flanks should be palpated in turn; the head is distinguished as a hard round body. The back as a smooth broad resistant surface; the extremities as small rounded knobs. auscultation reveals the position of the foetal heart and its rate, (page 97). pelvimetry or pelvic measurement shows the relative size of the pelvis, and although it should be a routine, the size of the foetal head is the real pelvimeter, (page 98). vaginal examination reveals the condition of the soft parts, the degree of dilatation of the cervix, the state of the membranes, and the position of the sutures and fontanelles in the vertex cases.
