The Pregnant Woman

Chapter 29


Structure and function

Structure and Function

  • Pregnancy and the endocrine placenta

    • First day of menses is day 1 of menstrual cycle

      • For first 14 days of cycle, one or more follicles in ovary develops and matures

      • One follicle grows faster than others, and on day 14 of cycle this dominant follicle ruptures and ovulation occurs

      • If ovum meets viable sperm, fertilization occurs somewhere in oviduct (fallopian tube)

      • Remaining cells in follicle form corpus luteum, or “yellow body,” which makes important hormones

        • Chief among these is progesterone, which prevents sloughing of endometrial wall, ensuring a rich vascular network into which fertilized ovum will implant


Structure and function cont

Structure and Function(cont.)

  • Pregnancy and the endocrine placenta (cont.)

    • Blastocyst, or fertilized ovum, continues to divide, differentiate, and grow rapidly

      • Specialized cells in blastocyst produce human chorionic gonadotropin (hCG), which stimulates corpus luteum to continue making progesterone

      • Between days 20 and 24, blastocyst implants into wall of uterus, and may cause small amount of vaginal bleeding

      • Specialized layer of cells around blastocyst becomes placenta

      • Placenta starts to produce progesterone to support pregnancy at 7 weeks and takes over this function completely from corpus luteum at about 10 weeks


Structure and function cont1

Structure and Function(cont.)

  • Pregnancy and the endocrine placenta (cont.)

    • Placenta functions as an endocrine organ and produces several hormones

      • These hormones help growth and maintenance of fetus, and direct changes in woman’s body to prepare for birth and lactation

      • The hCG stimulates rise in progesterone during pregnancy

      • Progesterone maintains endometrium around fetus, increases alveoli in breast, and keeps uterus in a quiescent state


Structure and function cont2

Structure and Function(cont.)

  • Pregnancy and the endocrine placenta (cont.)

    • Estrogen stimulates duct formation in breast

      • Also increases weight of uterus and increases certain receptors in uterus that are important at birth

      • Average length of pregnancy is 280 days from first day of last menstrual period (LMP), which is equal to:

      • 40 weeks

      • 10 lunar months

      • 9 calendar months

        • Note that this includes 2 weeks when follicle was maturing but before conception actually occurred


Structure and function cont3

Structure and Function(cont.)

  • Pregnancy and the endocrine placenta (cont.)

    • Pregnancy is divided into three trimesters

      • First trimester is the first 12 weeks

      • Second trimester is from 13 to 27 weeks

      • Third trimester is from 28 weeks to delivery

    • Woman pregnant for first time called primigravida

      • After she delivers, she is called a primipara

      • Multigravida: pregnant woman who has previously carried a fetus to the point of viability

      • Any pregnant woman might be called a gravida


Structure and function cont4

Structure and Function(cont.)

  • Pregnancy and the endocrine placenta (cont.)

    • Commonly used terminology is

      • G, gravida

      • P, para

      • T, term

      • PT, preterm deliveries

      • A, abortion—including missed, therapeutic, or voluntary

      • L, living children

    • It may be written as

      • G5 T3 PT0 A2 L3


Structure and function cont5

Structure and Function(cont.)

  • Changes during normal pregnancy

    • Pregnancy is diagnosed by three types of signs and symptoms

    • Presumptive signs are those woman experiences, such as amenorrhea, breast tenderness, nausea, fatigue, and increased urinary frequency

    • Probable signs are those detected by examiner, such as an enlarged uterus

    • Positive signs of pregnancy are those that are direct evidence of fetus, such as auscultation of fetal heart tones (FHTs) or positive cardiac activity on ultrasound (US)


Structure and function cont6

Structure and Function(cont.)

  • Changes during normal pregnancy: first trimester

    • Conception occurs on approximately 14th day of menstrual cycle

      • Blastocyst, which is the developing fertilized ovum, implants in uterus 6 to 10 days after conception, sometimes accompanied by small amount of painless bleeding

      • Serum hCG becomes positive after implantation when it is first detectable in maternal serum at approximately 8 to 11 days after conception

      • Following menstrual period is missed


Structure and function cont7

Structure and Function(cont.)

  • Changes during normal pregnancy: first trimester (cont.)

    • At time of missed menses, hCG can be detected in urine

      • Breast tingling and tenderness begin as rising estrogen levels promote mammary growth and development of ductal system; progesterone stimulates alveolar system as well as the mammary growth

      • Chorionic somatomammotropin (also called human placental lactogen or hPL), which is also produced by placenta, stimulates breast growth and exerts lactogenic properties


Structure and function cont8

Structure and Function(cont.)

  • Changes during normal pregnancy: first trimester (cont.)

    • More than half of all pregnant women have nausea and vomiting

      • Cause is unclear but may involve hormonal changes of pregnancy, low blood sugar, gastric overloading, slowed peristalsis, an enlarging uterus, and emotional factors

      • Fatigue is common and may be related to initial fall in metabolic rate that occurs in early pregnancy

      • Estrogen, and possibly progesterone, cause hypertrophy of uterine muscle cells and uterine blood vessels, and lymphatics enlarge


Structure and function cont9

Structure and Function(cont.)

  • Changes during normal pregnancy: first trimester (cont.)

    • Uterus becomes globular in shape, softens, and flexes easily over cervix (Hegar’s sign)

      • This causes compression of bladder, which results in urinary frequency

      • Increased vascularity, congestion, and edema cause cervix to soften (Goodell’s sign) and become bluish purple (Chadwick’s sign)

      • Early first-trimester blood pressures (BPs) reflect prepregnancy values


Structure and function cont10

Structure and Function(cont.)

  • Changes during normal pregnancy: first trimester (cont.)

    • In 7th gestational week

      • BP begins to drop until midpregnancy as a result of falling peripheral vascular resistance

      • Systemic vascular resistance decreases from vasodilatory effect of progesterone and prostaglandins

      • At end of 9 weeks, embryonic period ends and fetal period begins, at which time major structures are present

      • FHTs can be heard by Doppler US between 9 and 12 weeks

      • Uterus may be palpated at about 12 weeks


Height of fundus at weeks of gestation

Height of Fundus at Weeks of Gestation


Structure and function cont11

Structure and Function(cont.)

  • Changes during normal pregnancy: second trimester

    • By weeks 12 to 16

      • Nausea, vomiting, fatigue, and urinary frequency of first trimester improve

      • 18 to 20 weeks woman recognizes fetal movement (“quickening”)

      • As breast enlargement continues, the veins of breast enlarge and are more visible through skin of lightly pigmented women

      • Colostrum, precursor of milk, may be expressed from nipples


Structure and function cont12

Structure and Function(cont.)

  • Changes during normal pregnancy: second trimester (cont.)

    • Colostrum

      • Yellow in color, contains more minerals and protein but less sugar and fat than mature milk

      • Also contains antibodies, which are protective for newborn during its first days of life until mature milk production begins

      • Areola and nipples darken, it is thought, because estrogen and progesterone have a melanocyte-stimulating effect, and melanocyte-stimulating hormone levels escalate from second month of pregnancy until delivery


Structure and function cont13

Structure and Function(cont.)

  • Changes during normal pregnancy: second trimester (cont.)

    • For same reason, midline of abdominal skin becomes pigmented, called lineanigra

      • You may note striaegravidarum (“stretch marks”) on breast, abdomen, and areas of weight gain

      • Systolic BP may be 2 to 8 mm Hg lower and diastolic BP 5 to 15 mm Hg lower than prepregnancy levels

      • Drop most pronounced at 20 weeks and may cause symptoms of dizziness and faintness, particularly after rising quickly


Structure and function cont14

Structure and Function(cont.)

  • Changes during normal pregnancy: second trimester (cont.)

    • Stomach displacement from enlarging uterus and altered esophageal sphincter and gastric tone as a result of progesterone predispose woman to heartburn

    • Intestines are also displaced by growing uterus, and tone and motility are decreased because of action of progesterone, often causing constipation

    • Gallbladder, possibly resulting from action of progesterone on its smooth muscle, empties sluggishly and may become distended


Structure and function cont15

Structure and Function(cont.)

  • Changes during normal pregnancy: second trimester (cont.)

    • Stasis of bile, together with increased cholesterol saturation of pregnancy, predisposes some women to gallstone formation

    • Progesterone and, to lesser degree, estrogen cause increased respiratory effort during pregnancy by increasing tidal volume

    • Hemoglobin, and therefore oxygen-carrying capacity, also increases

    • Increased tidal volume causes slight drop in partial pressure of arterial carbon dioxide (PaCO2), causing woman to occasionally have dyspnea


Structure and function cont16

Structure and Function(cont.)

  • Changes during normal pregnancy: second trimester (cont.)

    • Cutaneous blood flow augmented during pregnancy caused by decreased vascular resistance, presumably helping to dissipate heat generated by increased metabolism

    • Gums may hypertrophy and bleed easily; condition is called gingivitis or epulis of pregnancy

    • For same reason, nosebleeds may occur more frequently

    • Pregnant women with periodontal disease, a chronic local oral infection, are at risk for preterm delivery

    • Untreated, this may lead to systemic infection that affects maternal levels of prostaglandin E2 (PGE-2)


Structure and function cont17

Structure and Function(cont.)

  • Changes during normal pregnancy: second trimester (cont.)

    • 17 to 19 weeks

      • FHTs are audible by fetoscope, as opposed to Doppler imaging

      • Fetal outline palpable through abdominal wall at approximately 20 weeks


Structure and function cont18

Structure and Function(cont.)

  • Changes during normal pregnancy: third trimester

    • Blood volume, which increased rapidly during second trimester, peaks in middle of third trimester at approximately 45% greater than prepregnancy level and plateaus thereafter

    • This volume is greater in multiple gestations

    • Erythrocyte mass increases by 20% to 30%, caused by an increase in erythropoiesis, mediated by progesterone, estrogen, and placental chorionic somatomammotropin

    • However, plasma volume increases slightly more, causing slight hemodilution and small drop in hematocrit


Structure and function cont19

Structure and Function(cont.)

  • Changes during normal pregnancy: third trimester (cont.)

    • BP slowly rises again to approximately prepregnant level

    • Uterine enlargement causes diaphragm to rise and shape of rib cage to widen at base

    • Decreased space for lung expansion may cause a sense of shortness of breath

    • Rising diaphragm displaces heart up and to left

    • Cardiac output, stroke volume, and force of contraction are increased

    • Pulse rate rises 15 to 20 beats per minute


Structure and function cont20

Structure and Function(cont.)

  • Changes during normal pregnancy: third trimester (cont.)

    • Because of increase in blood volume, a functional systolic murmur, grade ii/iv or less, can be heard in more than 95% of pregnant women (Creasy and Resnick, 2004)

    • Edema of lower extremities may occur as result of enlarging fetus impeding venous return, and from lower colloid osmotic pressure; worsens with dependency, such as prolonged standing

    • Varicosities, which have a familial tendency, may form or enlarge from progesterone-induced vascular relaxation


Structure and function cont21

Structure and Function(cont.)

  • Changes during normal pregnancy: third trimester (cont.)

    • Also causing varicosities is engorgement caused by weight of full uterus compressing inferior vena cava and vessels of pelvic area, resulting in venous congestion in legs, vulva, and rectum

    • Hemorrhoids are varicosities of rectum that are worsened by constipation, which occurs from relaxation of large bowel by progesterone

    • Progressive lordosis, an inward curvature of lumbar spine, occurs to compensate for shifting center of balance caused by anteriorly enlarging uterus, predisposing woman to backaches


Structure and function cont22

Structure and Function(cont.)

  • Changes during normal pregnancy: third trimester (cont.)

    • Slumping of shoulders and anterior flexion of neck from increasing weight of breasts may cause aching and numbness of arms and hands as a result of compression of median and ulnar nerves in arm, commonly referred to as carpal tunnel syndrome

    • Approximately 2 weeks before going into labor, primigravida experiences engagement, also called “lightening” or “dropping,” when fetal head moves down into pelvis


Structure and function cont23

Structure and Function(cont.)

  • Changes during normal pregnancy: third trimester (cont.)

    • Symptoms include lower-appearing and smaller-measuring fundus, urinary frequency, increased vaginal secretions from increased pelvic congestion, and increased lung capacity

    • In multigravida, fetus may move down at any time in late pregnancy or often not until labor

    • Cervix, in preparation for labor, begins to thin (efface) and open (dilate)

    • Thick mucous plug, formed in cervix as a mechanical barrier during pregnancy, is expelled at variable times before or during labor


Structure and function cont24

Structure and Function(cont.)

  • Changes during normal pregnancy: third trimester (cont.)

    • Between 37 and 42 weeks

      • Pregnancy is considered term

      • After 42 weeks, pregnancy is considered postdated


Structure and function cont25

Structure and Function(cont.)

  • Determining weeks of gestation

    • Expected date of delivery, or EDD

      • 280 days from first day of LMP, may be calculated by using Nägele’s rule

      • Determine first day of last normal menstrual period

      • Using first day of LMP, add 7 days and subtract 3 months

      • This is the EDD that can then be used with a pregnancy wheel, on which EDD arrow is set, and then present date will be pointing to present week’s gestation


Structure and function cont26

Structure and Function(cont.)

  • Determining weeks of gestation(cont.)

    • Expected date of delivery, or EDD (cont.)

      • Number of weeks of gestation also can be estimated by

        • Physical examination (bimanual and pelvic exam)

        • Measurement of maternal serum hCG

        • Ultrasound

        • Signs such as first perceived fetal movement


Structure and function cont27

Structure and Function(cont.)

  • Weight gain in pregnancy

    • Amount of weight gained by term

      • Represents a baby, amniotic fluid, placenta, increased uterine size, increased blood volume, increased extravascular fluid, maternal fat stores, and increased breast size

      • Weight gain during pregnancy reflects both mother and fetus and is approximately 62% water gain, 30% fat gain, and 8% protein

      • Approximately 25% of the total gain is attributed to the fetus, 11% to placenta and amniotic fluid, and remainder to mother


Structure and function cont28

Structure and Function(cont.)

  • Weight gain in pregnancy (cont.)

    • The American College of Obstetricians and Gynecologists recommends following weight gain during pregnancy

      • 28 to 40 lb for underweight women

      • 25 to 35 lb for normal-weight women

      • 15 to 25 lb for overweight women

      • 35 to 45 lb for twin gestation

    • A healthy outcome may be expected within a great range of weight gain


Structure and function developmental competence

Structure and FunctionDevelopmental Competence

  • Each year in U.S., almost one million teenage women become pregnant

    • 78% are unplanned

      • Many pose serious medical risks for both mother and fetus, such as toxemia, anemia, prematurity, low birth weight infants, prolonged labor, and postpartum complications

      • Some teen pregnancies are planned and due in part to maladaptive attempts to solve social issues within home environment or manipulation of a boyfriend with promise of a prolonged relationship


Structure and function developmental competence cont

Structure and FunctionDevelopmental Competence(cont.)

  • Each year in the U.S., almost one million teenage women become pregnant (cont.)

    • Either attempt can bring bitterness from family and friends leading to cycle of poor reproductive and social choices

    • It is important for those teens wishing to continue a pregnancy to seek early prenatal care because they are at risk for maternal/fetal morbidity and mortality


Structure and function developmental competence cont1

Structure and FunctionDevelopmental Competence(cont.)

  • Other risks for pregnant adolescents are largely psychosocial

    • This young woman is at risk for downward cycle of poverty beginning with an incomplete education, failure to limit family size, and continuing with failure to establish a vocation and become independent

    • She may be unprepared emotionally to be a mother

    • Her social situation may be stressful

    • She may not have the support of her family, her partner, or his family


Structure and function developmental competence cont2

Structure and FunctionDevelopmental Competence(cont.)

  • Other risks for pregnant adolescent are largely psychosocial (cont.)

    • Medical risks for pregnant adolescent are generally related to poverty, inadequate nutrition, substance abuse, and sometimes sexually transmitted infections (STIs), poor health before pregnancy, and emotional and physical abuse from her partner

    • Adolescents, for social reasons, seek health care later when early prenatal care provides optimal management

    • In developing countries, maternal mortality for pregnant teenagers is major concern because of hypertension, embolism, ectopic pregnancy, and complications from pregnancy termination where abortion is illegal


Structure and function developmental competence cont3

Structure and FunctionDevelopmental Competence(cont.)

  • Fertility

    • Declines with advancing maternal age

    • Due in part to a decrease in number and health of eggs to be ovulated, a decrease in ovulation, endometriosis, and early onset of menopause

      • According to the American Society for Reproductive Medicine there is an unrealistic expectation that medical science can undo effects of aging when women delay childbearing; therefore, more women of advanced maternal age are choosing to use donor eggs from younger women

      • The age of egg is important factor, not age of uterus


Structure and function developmental competence cont4

Structure and FunctionDevelopmental Competence(cont.)

  • As we come to end of baby boomers’ fertility, many women of advanced maternal age (40s and 50s) are choosing to become pregnant with assisted fertility

  • With this comes concern not only for physical and emotional well-being of mother, but of psycho-logical challenges that child growing up with parents of advanced age will face

  • Women age 35 and older experience an increased risk of intrauterine fetal death, pregnancy induced hypertension, gestational diabetes, and delivery by cesarean


Structure and function developmental competence cont5

Structure and FunctionDevelopmental Competence(cont.)

  • Risk of Down syndrome increases with maternal age

    • 1 in 1,250 at age 25

    • 1 in 1,000 at age 30

    • 1 in 400 at age 35

    • 1 in 100 at age 40

    • 1 in 30 at age 45


Structure and function developmental competence cont6

Structure and FunctionDevelopmental Competence(cont.)

  • Women age 35 years or older or who have a history of a genetic abnormality are offered genetic counseling, and the options of both prenatal diagnostic screening tests

  • Two prenatal diagnostic options are:

    • Chorionic villi sampling (CVS) performed between gestational weeks 11 and 13 in which small sample of chorionic villi is removed to analyze genetic makeup

    • Amniocentesis, which is performed between gestational weeks 15 and 20 in which a small amount of amniotic fluid is removed to analyze genetic makeup

    • Both associated with small risk of complications and miscarriage


Structure and function developmental competence cont7

Structure and FunctionDevelopmental Competence(cont.)

  • Prenatal screening involves a fetal anatomy ultrasound (US) scan and serum screening

    • There are two US scans used in genetic screening

      • Nuchal translucency (NT) done between gestational weeks 11 and 14, which measures a collection of fluid at nape of fetal neck

      • Detailed anatomy scan done between gestational weeks 18 and 20

      • Some facilities continue to use Integrated Prenatal Risk Profile (IPRP), which uses a first trimester US between 10 and 12 weeks to measure NT and maternal serum analysis and a second maternal serum blood draw in the second trimester; results are only received after second maternal blood draw


Structure and function developmental competence cont8

Structure and FunctionDevelopmental Competence(cont.)

  • There are two US scans used in genetic screening (cont.)

    • Because integrated screen requires a waiting period, the sequential screen was developed

      • Similar to IPRP, except that those whose risk for Down syndrome is increased after first blood draw are given an earlier option for prenatal diagnostic testing

    • Women of advanced maternal age (over 35 years old) experience increased risk of prenatal and neonatal deaths, pregnancy-induced hypertension, preterm delivery, small for gestational age (SGA), and large for gestational age (LGA) neonates, gestational diabetes, severe preeclampsia, anal sphincter tears, and cesarean deliveries


Structure and function cultural competence

Structure and FunctionCultural Competence

  • Over 30 million women worldwide have undergone female genital cutting, or female circumcision

  • Due to large racial demographic in U.S., more with this condition are seen in current clinical setting

  • These women are at an increased risk of perineal tears, wound infections, separation of episiotomies, postpartum hemorrhage and sepsis

  • Every minute, another woman dies in pregnancy or childbirth leaving children without a mother and families shattered struggling to care for those left behind


Structure and function cultural competence cont

Structure and FunctionCultural Competence(cont.)

  • Over 500,000 women die in childbirth each year

  • According to United Nations Populations Fund, this number remains globally high in an age where these deaths are preventable

  • 90% of these maternal deaths occur in Africa and Asia, and they occur from severe bleeding, sepsis, eclampsia, obstructed labor, and unsafe abortions

  • Many women who survive pregnancy and childbirth may suffer lifetime of physical and emotional complications such as vaginal or rectal fistula


Structure and function cultural competence cont1

Structure and FunctionCultural Competence(cont.)

  • Hispanic population within U.S. between 1990 and 2000 grew by more than 40%

  • It is projected that between 2000 and 2010 that will increase by another 34%

  • Hispanics had highest birth rate in 2003 with 82.2 births per 1,000 teen females aged 15 to 19

  • Still there are disparities in adequate access to preventative, prenatal, and dental care with these cultural groups along with Asian/Pacific islander, American Indian, and Alaskan Native populations


Structure and function cultural competence cont2

Structure and FunctionCultural Competence(cont.)

  • Pregnancy is not only a medical event, but also one with profound psychological and social meaning for woman and for her family and community

  • All cultures recognize pregnancy as a unique period in a woman’s life that surrounds special customs and beliefs that have been developed throughout the ages

  • Spiritual practices and beliefs either provide her with or without support

  • Understanding what role these beliefs and practices play in woman’s pregnancy helps health care provider to acknowledge cultural differences


Structure and function cultural competence cont3

Structure and FunctionCultural Competence(cont.)

  • Pregnancy is intensely personal and involves such charged issues as sexuality, relationships, contraception, nutritional practices, maternal weight gain, and abortion

  • You must be sensitive to these issues

  • You may begin by inquiring whether woman or her significant others have any special requests

  • This communicates your intention to respect cultural differences and preferences

  • Continuing rapport will help enable woman to bring up issues as they develop

  • A woman’s resistance to an action or a suggestion by clinician may represent a cultural issue


Structure and function cultural competence cont4

Structure and FunctionCultural Competence(cont.)

  • Such issues may also be held differently by woman and one or more of her significant others, and such situations must be handled with care

  • Examples of culturally-charged issues are:

    • Dietary practices

    • Sexuality during and after pregnancy

    • Preference for gender of care provider

    • Preference for gender of infant

    • Contraceptive usage

  • Use your skill to understand such preferences within a cultural context and accept rather than judge the person

  • Whenever safe and possible, respect such wishes; this enhances success of birth in psychosocial dimensions

Objective data cont7

Objective Data(cont.)

  • Breasts

    • Breasts are enlarged, perhaps with striae, and are very tender

      • Areolae and nipples enlarge and darken in pigmentation, nipples become more erect, and “secondary areolae,” mottling around areolae, may develop

      • Blood vessels of breast enlarge and may shine blue through more translucent chest wall

  • Breasts (cont.)

    • Because of lack of menses, instruct woman to perform BSE according to calendar on a monthly basis

      • Recall that some women have an embryologic remnant called a supernumerary nipple, which may or may not have breast tissue beneath it

      • Possibly mistaken previously for a mole, these occur under arm or in line directly underneath each nipple on abdominal wall

      • This nipple and breast tissue may show same changes during pregnancy

      • Instruct woman to check these areas as well during BSE


Objective data cont10

Objective Data(cont.)

  • Heart

    • Pregnant woman often has functional, soft, blowing, systolic murmur as result of increased volume

      • Murmur requires no treatment and will resolve after pregnancy

Objective data1

Objective Data

  • Inspect and palpate the abdomen

    • Observe shape and contours of abdomen to discern signs of fetal position

      • As the woman lifts her head, you may see diastasis recti, separation of abdominal muscles, which occurs during pregnancy, with muscles returning together after pregnancy with abdominal exercise

      • When palpating, note abdominal muscle tone, which grows more relaxed with each subsequent pregnancy

      • Note any tenderness; uterus is normally nontender

      • Fundus should be palpable abdominally from 12 weeks of gestation on


Objective data cont12

Objective Data(cont.)

  • Inspect and palpate the abdomen (cont.)

    • Use side of hand and begin palpating centrally on abdomen higher than you expect uterus to be

      • Palpate down until you feel fundus (top of uterus)

      • Alternatively, stand at woman’s right side facing her head

      • Place palm of your right hand on curve of uterus in left lower quadrant and your left palm on curve of uterus in right lower quadrant

      • Moving from hand to hand, allowing curve of uterus to guide you, “walk” your hands to where they meet centrally at fundus


Objective data cont13

Objective Data(cont.)

  • Inspect and palpate the abdomen (cont.)

    • Note fundal location by landmarks

      • More accurate to use centimeter measuring tape and measure height of fundus in centimeters from superior border of symphysis to fundus

      • After 20 weeks, number of centimeters should approximate number of weeks of gestation

      • Beginning at 20 weeks, you may feel fetal movement, and fetus’s head can be ballotted

      • Gentle, quick palpation with fingertips can locate head that is not only hard when you push it away, but hard as it bobs or bounces back against your fingers


Objective data cont14

Objective Data(cont.)

  • Inspect and palpate the abdomen (cont.)

    • If you suspect woman to be in labor, palpate for uterine contractions

      • Palpate uterus over its entire surface to familiarize yourself with its “indentability”

      • Then rest your hand lightly on uterus with fingers opened

      • When uterus contracts, it rises and pulls together, drawing your fingers closer together

      • During contraction, notice that uterus is less “indentable”

      • When uterus relaxes, your fingers relax open again


Objective data cont15

Objective Data(cont.)

  • Inspect and palpate the abdomen (cont.)

    • In this way, contractions can be monitored for frequency, length, and quality

      • Mild contraction feels like firmness of tip of your nose

      • Moderate contraction feels like your chin

      • Hard contraction feels like a forehead

        • Make allowance for the amount of soft tissue between your fingers and the uterus


Objective data cont16

Objective Data(cont.)

  • Leopold’s maneuvers

    • In third trimester, perform Leopold’s maneuvers to determine fetal:

      • Lie

      • Presentation

      • Attitude

      • Position

      • Variety

      • Engagement


Objective data cont17

Objective Data(cont.)

  • Leopold’s maneuvers(cont.)

    • Fetal lie: orientation of fetal spine to maternal spine;may be longitudinal, transverse, or oblique

    • Presentation: describes part of fetus entering pelvis first

    • Attitude: position of fetal parts in relation to each other, and may be flexed, military (straight), or extended

    • Position: designates location of fetal part to right or left of maternal pelvis

    • Variety: location of fetal back to anterior, lateral, or posterior part of the maternal pelvis

    • Engagement: when widest diameter of presenting part has descended into pelvic inlet; specifically, to imagined plane at level of ischial spines


Objective data cont18

Objective Data(cont.)

  • Leopold’s maneuvers: first maneuver

    • Performed by facing gravida’s head and placing your fingertips around top of fundus

      • Note its size, consistency, and shape

      • Imagine what fetal part is in fundus

      • Breech feels large and firm because it is attached to fetus at waist

      • In contrast, fetal head feels large, round, and hard

        • When ballotted, it feels hard as you push it away and hard again as it bobs back against your fingers


Objective data cont19

Objective Data(cont.)

  • Leopold’s maneuvers: first maneuver (cont.)

    • Note that “bobbing” or “ballotting” sensation of movement occurs because head attached at neck and moves easily

      • If there is no part in fundus, fetus is in the transverse lie


Objective data cont20

Objective Data(cont.)

  • Leopold’s maneuvers: second maneuver

    • Move your hands to sides of uterus

      • Note whether small parts or a long, firm surface palpable on woman’s left or right side

      • Long, firm surface is the back

      • Note whether back is anterior, lateral, or out of reach (posterior)

      • Small parts, or limbs, indicate a posterior position when they are palpable all over abdomen


Objective data cont21

Objective Data(cont.)

  • Leopold’s maneuvers: third maneuver

    • Also called Pawlik’s maneuver, requires woman to bend her knees up slightly

      • Grasp lower abdomen just above symphysis pubis between thumb and fingers of one hand and, as you did at fundus during first maneuver, to determine what part of fetus is there

      • If presenting part is beginning to engage, it will feel “fixed”

      • With this maneuver alone, it may be difficult to differentiate shoulder from vertex


Objective data cont22

Objective Data(cont.)

  • Leopold’s maneuvers: fourth maneuver

    • Assists in determining engagement and, in vertex presentation, to differentiate shoulder from vertex

      • Woman’s knees are still bent

      • Facing her feet, place your palms, with fingers pointing toward feet, on either side of lower abdomen

      • Pressing your fingers firmly, move slowly down toward pelvic inlet

      • If your fingers meet, presenting part is not engaged

      • If your fingers diverge at pelvic rim meeting a hard prominence on one side, this prominence is the occiput


Objective data cont23

Objective Data(cont.)

  • Leopold’s maneuvers: fourth maneuver (cont.)

    • This indicates vertex is presenting with a deflexed head, the face presenting

      • If your fingers meet hard prominences on both sides, vertex is engaged in either a military or a flexed position

      • If your fingers come to pelvic brim diverged but with no prominences palpable, vertex is “dipping” into pelvis, or is engaged

      • In this case, firm object felt above symphysis pubis in the third maneuver is shoulder


Objective data cont24

Objective Data(cont.)

  • Auscultate the fetal heart tones

    • FHTs are positive sign of pregnancy

      • They can be heard by Doppler US at 8 to 10 weeks’ gestation and with a fetoscope at 20 weeks’ gestation

      • This use of fetoscope assists in dating pregnancy

      • FHTs are auscultated best over shoulder of fetus

      • After identifying position of fetus, use heart tones to confirm your findings

      • Count FHTs for 15 seconds and multiply by four to obtain the rate

      • Normal rate is between 120 and 160 beats per minute


Objective data cont25

Objective Data(cont.)

  • Auscultate the fetal heart tones (cont.)

    • Spontaneous accelerations of FHTs indicate fetal well-being

      • Differentiate FHTs from slower rate of maternal pulse and uterine souffle (the soft, swishing sound of the placenta receiving the pulse of maternal arterial blood) by palpating the mother’s pulse while you listen

      • Also, distinguish FHTs from funic souffle (blood rushing through umbilical arteries at same rate as FHTs)

      • FHTs are a double sound, like tick-tock of a clock under a pillow, whereas funic souffle is sharp, whistling sound heard only 15% of time


Objective data cont26

Objective Data(cont.)

  • Pelvic examination

    • Genitalia

      • Use procedure for pelvic examination described in Chapter 26

      • Note presence of any hemorrhoids of rectum


Objective data cont27

Objective Data(cont.)

  • Pelvic examination (cont.)

    • Speculum examination

      • When examining vagina, you may see Chadwick’s sign, the bluish-purplish discoloration and congested look of vaginal wall and cervix from increased vascularity and engorgement

      • Note vaginal discharge; discharge in pregnancy may be heavier in amount but should be similar in description to woman’s nonpregnant discharge and should not be associated with itching, burning, or an unusual odor (except that, occasionally, chapping of vaginal area may be seen due to excessive moisture)


Objective data cont28

Objective Data(cont.)

  • Pelvic examination(cont.)

    • Speculum examination (cont.)

      • Perform a wet mount or culture of discharge when you are uncertain of its normalcy

      • Note whether cervix appears open

      • Note whether it is smooth, round cervix with a dotlike external os of nulliparous woman or irregular multiparous cervix with an external os that appears more like a crooked line, result of cervical dilation and possibly lacerations in a previous pregnancy


Objective data cont29

Objective Data(cont.)

  • Pelvic examination (cont.)

    • Bimanual examination

      • Palpate the uterus between your internal and external hands; note its position

      • Pregnant uterus may be rotated toward right side as it rises out of pelvis because of presence of descending colon on left

      • This is called dextrorotation; irregular enlargement of uterus may be noted at 8 to 10 weeks of gestation and occurs when implantation occurs close to a cornual area of uterus

      • This is called Piskacek sign


Objective data cont30

Objective Data(cont.)

  • Pelvic examination(cont.)

    • Bimanual examination (cont.)

      • May also note Hegar’s sign, when enlarged uterus bends forward on its softened isthmus between 4th and 6th weeks of pregnancy

      • Note size and consistency of uterus

      • 6-week gestation uterus may seem only slightly enlarged and softened

      • 8-week gestation uterus is approximately size of an avocado, approximately 7 to 8 cm across fundus

      • 10-week gestation uterus about size of grapefruit and may reach to pelvic brim, but is narrow and does not fill pelvis from side to side


Objective data cont31

Objective Data(cont.)

  • Pelvic examination(cont.)

    • Bimanual examination (cont.)

      • 12-week gestation uterus will fill pelvis

      • After 12 weeks, uterus is sized from abdomen

      • Softening of cervix is called Goodell’s sign

      • When examining cervix, note its position (anterior, midposition, or posterior), degree of effacement (or thinning, expressed in percentages assuming a 2-cm long cervix initially), dilation (opening, expressed in centimeters), consistency (soft or firm), and station of presenting part (centimeters above or below ischial plane)


Objective data cont32

Objective Data(cont.)

  • Pelvic examination(cont.)

    • Bimanual examination (cont.)

      • Ovaries rise with growing uterus; always examine adnexae to rule out presence of a mass, such as an ectopic pregnancy

      • To determine tone, ask woman to squeeze your fingers as they rest in vagina

      • Take this opportunity to teach Kegel exercise, squeezing of vagina, which woman can do to prepare for and to recover from birth

        • Woman can also identify exercise of these muscles by stopping flow of urine midstream, although she should only do this once, and should usually let urine flow freely


Objective data cont33

Objective Data(cont.)

  • Pelvic examination(cont.)

    • Bimanual examination (cont.)

      • Direct woman to squeeze slowly to a peak at count of eight and then release slowly to count of eight

      • You can prescribe this exercise to be performed 50 to 100 times a day


Objective data cont34

Objective Data(cont.)

  • Pelvimetry

    • Assess bones of the pelvis for shape and size

      • Dimensions may indicate favorableness of bony structure for vaginal delivery

      • However, relaxation of pelvic joints, widening of pelvis in squatting position, and capacity of fetal head to mold to shape of pelvis may enable a vaginal birth despite seemingly unfavorable measurements

      • To aid in visualizing pelvis, imagine three planes:

        • Pelvic inlet, from sacral promontory to upper edge of pubis

        • Midpelvis, and pelvic outlet, from coccyx to lower edge of pubis


Objective data cont35

Objective Data(cont.)

  • Pelvimetry (cont.)

    • Assessment of each of these pelvic planes allows you to estimate adequacy of pelvis for vaginal delivery

      • There are four general types of pelves: gynecoid, anthropoid, android, and platypelloid

        • You may postpone examination of bony pelvis until third trimester when vagina is more distensible

      • With your two fingers still in the vagina, note shape and width of pubic arch (a 90-degree arch, or 2 fingerbreadths, is desirable)


Objective data cont36

Objective Data(cont.)

  • Pelvimetry (cont.)

    • If you are right-handed, move your hand to right side of woman’s pelvis

    • If you are left-handed, move it to left side of woman’s pelvis

    • Assess the inclination and curve of side walls and prominence of ischial spine

    • Move your fingers back and forth between spines to get an impression of transverse diameter; 10 cm is desirable

    • Sweep your fingers down sacrum, noting its shape and inclination (hollow, J-shaped, or straight)

    • Assess coccyx for prominence and mobility


Objective data cont37

Objective Data(cont.)

  • Pelvimetry (cont.)

    • From sacrum, locate sacrospinous ligament

    • Assess length of the ligament; 2½ to 3 fingerbreadths is adequate

    • Assess shape and width of sacrospinous notch

    • Shift to other side of pelvis and assess it for similarity to the first

    • The pelvic inlet cannot be reached by clinical examination, but you can estimate it by measure of diagonal conjugate, which indicates anteroposterior diameter of pelvic inlet

    • Having measured length of second and third fingers of your examining hand, with your fingers still in vagina, point these fingers toward sacral promontory


Objective data cont38

Objective Data(cont.)

  • Pelvimetry (cont.)

    • If you cannot reach promontory, note measurement as being greater than centimeters of length of your examining fingers; measurement of 11.5 to 12.0 cm is desirable

    • Remove your fingers from vagina

    • Having previously measured width of your own hand across knuckles, form your hand into a closed fist and place it across perineum between ischialtuberosities.

    • Estimate this diameter, which is bi-ischial diameter (also known as the intertubous diameter and transverse diameter of pelvic outlet)

    • Measurement greater than 8 cm is generally adequate


Objective data cont39

Objective Data(cont.)

  • Pelvimetry (cont.)

    • When describing pelvimetry, note all above measurements and state pelvic type

      • Pelvis may be described as being “proven” to number of pounds of largest vaginally-born infant

      • Alternatively, to describe a small pelvis, you may make assessment, for example, “adequate for a 7-lb infant”

  • Blood pressure

    • After examination, take blood pressure when woman is most relaxed, in semi-Fowler’s or upright position

      • Recheck an elevated pressure


Objective data cont40

Objective Data(cont.)

  • Routine laboratory and radiologic imaging studies

    • At onset of pregnancy, order routine prenatal panel

      • Usually includes complete blood cell count, serology, rubella antibodies, hepatitis B screening, blood type and Rhesus factor, and an antibody screening

      • Some providers screen for herpes simplex virus I and II

      • Sickle cell screening may be indicated

      • For some populations, a PPD/TINE test may be indicated to rule out active or exposure to tuberculosis


Objective data cont41

Objective Data(cont.)

  • Routine laboratory and radiologic imaging studies (cont.)

    • Offer woman HIV screening and cystic fibrosis screening

      • Obtain Papanicolaou smear at initial visit along with cervical cultures

      • Collect a clean-catch urinalysis at initial prenatal visit to rule out cystitis

      • At each prenatal visit, check urine for protein and glucose

        • Clean-catch specimen ideal for this dip because a random specimen may include vaginal secretions, which contain protein, skewing results


Objective data cont42

Objective Data(cont.)

  • Routine laboratory and radiologic imaging studies (cont.)

    • Each agency has policy regarding frequency of US exam

    • Some providers prefer to do US for dating at time of maternal serum alpha-fetoprotein or “quad” screening is drawn because accurate dating is essential

    • Others will do it later (11 to 14 weeks of gestation), when measuring for fetal nuchal translucency (another fetal risk screening tool), which is best done at this gestation

    • Some providers use US only with a medical indication


Objective data cont43

Objective Data(cont.)

  • Routine laboratory and radiologic imaging studies (cont.)

    • Others routinely order US to confirm dates and fetal normalcy (insofar as US is able to determine normalcy) and for any specific medical indication, such as fundus measuring small or large for dates

    • US shows placental and fetal location and fetal gender
