Reproductive Health Definition of terms: HEALTH – state of physical, mental, social well – being and not merely the absence of disease or infirmity. REPRODUCTIVE HEALTH – addresses the reproductive processes, functions and system at all stages of life. REPRODUCTION – biological process where a new individual is produced. PHILIPPINE REPRODUCTIVE HEALTH (Cairo, Egypt – 1994) - Established by the AO 1-As.1998 by DOH - AO 43, s.1999 o Was issued adopting reproductive health policy to integrate reproductive health services in all health facilities as part of basic package of health services and thus ensuring more efficient and effective referral system from primary to tertiary, public and private facilities. Main Objectives: 1. Reducing maternal mortality rate. 2. Reducing child mortality. 3. Halting and reserving spread of HIV and AIDS *HIV – blood transfusion, trans – placental, sexual intercourse. - Abstinence - Be faithful - Condom - Drug avoidance - Education campaign - F*** yourself 4. Increasing access to reproductive health information and services. TEN ELEMENTS OF REPRODUCTIVE HEALTH 1. Family planning. 2. Prevention and management of reproductive tract infections (RIH) including STI’s and HIV/AIDS. *Benzathine penicillin 3. Maternal and child health nutrition (MSC & N). 4. Adolescent reproductive health (ARH). 5. Prevention and management of abortion and its complications (PMAC). 6. Education and counseling on sexuality and sexual health, men’s reproductive health (MRH) and involvement. 7. Prevention and management of breast and reproductive tract cancers and other gynecological conditions. 8. Violence against women and children (VAW). 9. Prevention and management of infertility and sexual dysfunction. THE MENSTRUAL CYLCE / FEMALE REPRODUCTIVE CYCLE A. Purpose: to bring an ovum to maturity and renew a uterine tissue bed that will be responsible for its growth should it be fertilized. B. Definition of Terms: CLIMACTERIC – period of a woman’s life when she is passing from a reproductive to a non – reproductive state, with regression of ovarian function. MENSTRUATION – periodic vaginal discharge of bloody fluid from non – pregnant uterus that occurs from the age of puberty to menopause. MENSTRUAL CYCLE – a complex interplay of events that occurs simultaneously in the uterus, hypothalamus and pituitary glands and the ovaries that results in ovarian and uterine preparation for pregnancy.

MENOPAUSE – cessation of menstrual cycle. OVULATION – periodic ripening the discharge of ovum from the ovary, usually 14 days before the menstrual flow. MITTELSCHEMERZ – localized lower abdominal pain that coincides with ovulation. SPINNBARKEIT – property of the cervical mucous to stretch a distance before breaking. FERNING – a ferning pattern of cervical mucus occurs with high estrogen levels. C. Characteristics of a Normal Menstrual Cycle MENARCHE Onset: 11 – 13 years old Range: 9 – 17 years old INTERVAL Average: 28 days Unusual: 23 – 35 days DURATION Average: 2 – 7 days Range: 1 – 9 days AMOUNT 30 – 80 mL / menstrual period Saturating pad / tampon in less than an hour is heavy bleeding. COLOR Dark red; blood mucus, endometrial cells. ODOR Similar to that of marigolds. D. Physiology of Menstrual Cycle 1. Hypothalamus a. Factors affecting GnRH release i. Estrogen ii. Progesterone iii. Prolactin iv. FSH v. LH b. Release GnRH (LNRH) which initiates menstrual cycle. c. Sensitive to estrogen produce by adrenal glands during childhood. d. Becomes less sensitive to estrogen feedback beginning puberty. 2. Pituitary Gland a. Produces 2 hormones that influence the menstrual cycle. b. FSH, active early in the cycle and responsible for the maturation of the ovum. c. LH, most active hormone at the midpoint of the cycle, responsible for ovulation and growth of the uterine lining during the second half of the menstrual cycle. *Adenohypophysis – anterior pituitary gland 3. Ovary a. FSH and LH cause growth in the gonads. b. Ovarian cycle occurs. i. Ovarian Cycle 1. Follicular Phase • Period during which an ovum matures. • FSH and LH levels rise slightly. • Primordial follicle produces a clear fluid (follicular fluid), high in estrogen (estradiol) and some progesterone (Graafian follicle). 2. Ovulatory Phase • Marks the beginning of the luteal phase and occurs about 14 days before the next menstrual period. 3. Luteal Phase • LH acts on the old follicle causing it to produce a bright yellow fluid (Lutein), high in progesterone and some estrogen (corpus luteum).

4. Uterus a. Menstrual cycle occurs. i. Menstrual Cycle 1. Proliferative Phase • Estrogenic, Follicular, Post – menstrual Phase • Day 5 – 14 • The endometrium proliferates approximately eightfold 2. Secretory Phase • Progestational, Luteal, Premenstrual Phase • Blood vessels and endometrium become corkscrew or twisted in appearance and dilated with quantities of glycogen, proteins, lipids and minerals. 3. Ischemic Phase • The blood supply to the functional endometrium is blocked and necrosis develops. • The functional layer separates from the basal layer and menstrual bleeding begins making day 1 of next cycle. 4. Menstrual Phase • Shedding of the functional 2/3 of the endometrium. • The basal layer is always retained. • Regeneration begins near the end of the cycle from cells derived from the remnants in the base. DEVELOPMENTAL STAGES A. Ante - partal - A term used to describe the period before labor or birth. 1. FETAL DEVELOPMENT a. Fertilization (zygote) • Also referred to as conception, impregnation, fecundation. • The union of an ovum and spermatozoa which usually occurs in the outer third layer of fallopian tube (ampulla). • “The Beginning of Pregnancy” • Ovum: Life – 24 – 48 hours Zona Pellucida – a ring of muco polysaccharide fluid. Corona Radiata – a circle of cells. • Spermatozoon: Life – 48 – 72 hours Capacitation – final process that a sperm must undergo to be ready for fertilization. Hyaluronidase – proteolytic enzyme produced by the sperm to… Semen – 2.5 mL (50 – 200 million / mL) Average of 400 million/mL/ejaculation b. Implantation (embryo) • Contact between the growing structure and the uterine endometrium. • Occurs approximately 8 – 10 days after fertilization at the upper part of the uterus. • It takes 3 – 4 days for the zygote to journey to the uterus where mitotic cell division happens. • Floats in the uterus for 3 – 4 days. • MORULA: because of the outward – bumpy appearance o “Morus” mulberry; 15 – 50 cells • BLASTOCYST: one which will attach to the uterine wall.

Trophoblast – outer layer that will form the placenta and membrane. o Embryoblast – forms the embryo. • Implantation Bleeding – mistaken as menstrual period. - 4 weeks late calculation of pregnancy. c. Stages of Fetal Development i. Fertilized Ovum • From conception through first 2 weeks of pregnancy. • Nidation complete by the end of this period. • Embryo: 2nd – 8th week (critical time for development). • Fetus: end of the 8th week to termination of pregnancy. • Organ systems develop from 3 primary germ layers. a. Ectoderm – brain and spinal cord, peripheral nervous system, pituitary gland, sensory epithelium of the eye, ear, and nose, epidermis, hair nails, subcutaneous glands, mammary glands and tooth enamel. b. Mesoderm – cartilage, bone, connective tissue, muscle tissue, heart, blood vessels, blood cells, lymphatic system, spleen, kidneys, adrenal cortex, reproductive system and lining membranes (pericardial, pleural, peritoneal). c. Endoderm – lining of GIT, RT, urinary bladder, urethra and ear canal, tonsils, thyroid, parathyroid, thymus, liver, and pancreas. ii. Measurements of Length of Pregnancy • Days: 267 – 280 • Weeks: 40, plus or minus 2 • Months: lunar (10); calendar (9) • Trimester: 3 iii. Expected date of Delivery (EDC/EDD) • Nagele’s Rule – most common method in computing EDD. a. Add 7 days to the first day of the last normal menstrual period. b. Subtract 3 months. c. Add 1 year. • McDonald’s Rule a. fundic height (cm) x 2/7 = AOG in lunar months. b. Fundic height (cm) x 8/7 = AOG in weeks. • Bartholomew’s Rule a. 12 weeks – level of umbilicus b. 16 weeks – halfway between umbilicus and symphysis pubis. c. 20 weeks – level of umbilicus. d. 24 weeks – 2 fingers above the umbilicus e. 28 – 30 weeks – halfway between umbilicus and xyphoid process. f. 40 weeks – at 34 weeks due to lightening. iv. Time Table Development All systems in rudimentary form; heart chambers formed and is beating. L= 0.4 – 0.5 cm long; Wt. = 0.4 g Some distinct features in face, head large in proportion to rest of body, some movement. L = 2.5 cm; Wt. = 0.4 g o

Date 4 weeks 8 weeks

12 weeks 16 weeks 20 weeks 24 weeks 28 weeks 32 weeks 36 weeks 40 weeks

Sex distinguishable; ossifications in most bones, kidneys secrete urine, able to such and swallow. More human appearance; earliest movement likely to be felt by mother. L = 11.5 – 13.5 cm; Wt. = 100 g. Vernix caseosa and lanugos appear heart rate audible, bones hardening. L = 16 – 18.5 cm; Wt = 3oo g. Body well proportioned; skin red and wrinkled, hearing established. Infant viable, but immature if born at this time, body less wrinkled, appearance of nails. L = 27 cm; Wt = 1100 g. Subcutaneous fat beginning to deposit, L/S ration in lungs now 1.2:1, skin smooth and pink. Lanugos disappearing; L/S ratio 2:1 L = 35 cm; Wt = 2200 – 2900g Full term pregnancy. Baby is active, with good muscle tone; strong suck reflex, little lanugos. L = 40 cm; Wt = 3200 g or more. d. Products of Conception i. Fetus ii. Membranes (bag of waters) – 2 fetal membranes composed of the amnion (inner membrane) and the chorion (outer membrane). iii. Amniotic Fluid – clear, yellowish, fluid surrounding the developing fetus. • Derived from fetal urine and fluid transported from the maternal blood across the amnion. • Increases until 500 – 1500 mL at term • Protects fetus and promote normal prenatal development. • Allows free movement. • Maintains temperature. • Provides oral fluid. • *Volume is important factor in assessing fetal well – being. a. Oligohydramnios – abnormal small quantity of fluid which is less than 500 mL. 1. associated with poor fetal lung development malformations that results from compression of fetal parts. 2. may occur because the kidneys fail to develop, urine excretion is blocked, or placental blood flow is inadequate. b. Hydramnios (Polyhydramnios) – more than 2000 mL of amniotic fluid.  May occur when the fetus has a sever malformation of the CNS or GIT that prevents normal ingestion of amniotic fluid. iv. Placenta – is a thick, disk shaped organ composed of 15 – 20 cotyledons (maximum of 30). • Fetal side, smooth with branching vessels covering the membrane – covered surface. • Maternal side, rough where it attaches to the uterus. • Major functions include; metabolic, transfer of substances between mother and fetus, endocrine. • Presentation: Duncan (dirty) or Schultz/e (shiny). • Hormones produce by the placenta:

a. Human Chorionic Gonadotropin (HCG) – ensures a continued supply of estrogen and progesterone needed to maintain the pregnancy.  Basis of pregnancy test. b. Chorionic Somatomammotropin or Human Placental Lactogen – similar to a growth hormone and stimulates maternal metabolism to supply needed nutrients for fetal growth.  Prepares breasts for lactation. c. Progesterone – maintains the endometrium  Decreases the contractility of the uterus.  Stimulates development of breast alveoli and maternal metabolism. d. Estrogen – stimulates uterine growth and utero placental blood flow. v. Umbilical Cord • Lifeline between fetus and placenta. • Contains 2 arteries and 1 vein (AVA) • Cushioned by a soft substance called WHARTON’s jelly to prevent obstruction due to pressure. • No pain receptors in the umbilical cord. • At term: 2 cm in diameter; 30 – 90 cm in length. e. Fetal Circulation i. 2 arteries – carry deoxygenated blood. ii. 1 vein – carry oxygenated blood iii. Ductus Venosus – connects umbilical vein and inferior vena cava, largely bypassing liver and closes after birth. iv. Foramen Ovale – allows blood flow from right atrium to left atrium, bypassing lungs and closes immediately after birth. v. Ductus Arteriosus – allows blood flow from pulmonary artery to aorta, bypassing fetal lungs. vi. Diagram of Fetal Circulation 2. MATERNAL CHANGES DURING PREGNANCY  Psychological Changes of Mother o 1st Trimester – accepting pregnancy. o 2nd Trimester – accepting the baby. o 3rd Trimester – preparation for parenthood.  Couvade Syndrome – father experiences fatigue, nausea, vomiting, back pain.  Pregnancy is a period for: o The needs of the fetus. o Meeting the stress of pregnancy and labor.  Changes during pregnancy can be: o Metabolic – chemical o Physiological – function o Anatomical – physical  Reproductive System • Uterus – increases from 60 gm to 1000gm o Hypertrophy of myometrial cells growing fetus. o 1/6 of maternal blood volume is contained in uterus at the end of the pregnancy. o Braxton Hick’s contraction – painless intermittent contractions.







o Uterine position over time – weeks. • Cervix – mucous plug; seals cervix o Goodell’s sign: softening the cervix o Chadwick’s sign: bluish discoloration of the cervix, vagina, and labia. o Hegar’s sign: softening of the lower uterine segment. • Breasts – enlarged and more nodular o Nipples are erectile. o Areolas darken o Colostrums – last trimester Respiratory System • Increase in O2 consumption and volume of air. • Diaphragm is pushed upward; breathing changes from abdominal to chest.

Urinary System • Glomerular filtration rises by 50 % due to increase cardiac output. • Glycosuria – excretion of glucose in the urine. • Frequency during and third trimester due to pressure on bladder. • The diameter of the uterus and the bladder capacity increase causing stasis. • Susceptible to UTI. • Gestational DM – glycosuria.









Gastrointestinal • Morning sickness – occurs due to elevated levels of estrogen and progesterone. • *Cardiac sphincter is relaxed due to high levels of progesterone; mother is more prone to GERD (Gastro-esophageal Reflux Disease). • What can you do about morning sickness? o Eat crackers, toast or dry cereal. o Eat small, frequent meals (there is tie for digestion and absorption.) o Limit fried, fatty and spicy foods (triggers production of HCL). o Drink liquids in between meals. o Have a snack before bed. o Sleep in a well ventilated room. Musculoskeletal System • Joints of pelvis relax due to hormone – relaxin. • Waddling gait • Center of gravity changes • Diastasis recti – separation of rectus abdominis muscle. • Lordosis is common due to the change of the body’s center of gravity; PRIDE OF PREGNANCY. Integumentary • Chloasma – increases pigmentation over bridge of nose and cheeks; THE MASK OF PREGNANCY. • Linea Nigra – mark vertical line that appears on the abdomen during the pregnancy. • Linea Alba – white line • Striae Gravidarum – stretch marks Weight Gain • Normal Range o Pre – pregnant BMI – 25 – 35 pounds (30 is ideal) o Baby – 8 pounds o Placenta – 2 – 3 pounds • Overweight: 28 – 40 pounds • Underweight – 15 – 25 pounds

3.

Before pregnancy, if you were:  Underweight – gain 28 to 48 pounds.  Normal weight – gain 25 – 35 pounds.  Overweight – gain 15 – 25 pounds  Obese – gain 15 – 18 pounds. Simple diffusion – transport oxygen to fetus Organogenesis – 1st trimester. Nutritional Requirement  Calorie increase: 800 kcal per day  Growth of the fetus  Placenta  Amniotic fluid  Maternal tissue Important Nutrients Needed by Pregnant Women  CHON – 60 mg/day: metabolism – development of muscles.  Sources: meat, fish, poultry, and dairy products, beans.  Calcium – 1200 mg: dairy products, nuts dried fruits, canned salmon and sardines.  1000 – 1200 mg daily intake.  Iron – 30 mg/day: dried beans, fish, dried fruit, liver, nuts.  Iron is found in two forms: o Heme – red and organ meats. o Non heme – plant products.  Folic Acid – reduce incidence of neural tube defects.  RDA: 400 mcg (0.4 mg): liver o May cause meningomyelocele.  Fluids – 8 – 12 glasses/day; limit caffeine consumption to 2 cups/day.  Sodium Intake – restricted: edema and gestational HPN.  Iodine salt – better brain development.

If the woman is hooked on drugs, chances are the baby is too. The baby will go through a “withdrawal” once it is born.  Radiation exposure  Environmental pollution Classification of Pregnancy  Gravida – number of times pregnant regardless of duration, including present pregnancy.

 Primigravida – pregnant for the first time.  Multigravida – a woman who has 2 or more pregnancy.  Nulligravida – a woman who has never been pregnant.  Para – number of pregnancy that lasted more than 20 weeks regardless of outcome.  Primipara – a woman who has given birth to a baby beyond 20 weeks of gestation.  Multipara – had two or more births to a baby beyond 20 weeks of gestation.  Nullipara – has not given birth to a baby beyond 20 weeks of gestation.  Postdate/post term – beyond 42 weeks of gestation.  Preterm – has reached 20 weeks of gestation but before completion of 37 weeks of gestation.  Term – a pregnancy from beginning 38th week of gestation to the end of the end of the 42nd weeks of gestation.  Viability – capacity to live outside the uterus approximately 22 – 24 weeks since LMP or weight of fetus is greater than 500 grams.  TPAL – para subdivided to reflect births that went Term, Premature births, Abortion, and Living children. 4. FETAL ASSESSMENT • Fetal diagnostic tests o Used to:  Identify or confirm existence of risk factors.  Validate pregnancy.  Observe process of pregnancy.  Identify genetic abnormalities. o Chronic Villi Sampling (CVS)  Provides chromosomal studies of fetal cells.  Getting a sample of the chronic villus (placental tissue)  Done at 10 – 12 weeks of gestation  1 % risk of confined placental mosaicism o Amniocentesis  Small amount of fluid from the amniotic sac is withdrawn to look for the birth defects and chromosome problems.  15 – 20 weeks gestation  Detects: down’s syndrome, spina bifida, fetal lung maturity.  For Rh – incompatibility. o Ultrasound / sonogram  Sound waves bounce of the fetus to produce an image of the fetus inside the womb.  Determines gestational age.  Diagnose multiple pregnancies.  Identify congenital anomalies  Fetal viability. • Types: o Trans vaginal UTZ – used during early pregnancy. o Standard UTZ (2D) o 3D – more detailed o Doppler UTZ – provides information about blood flow and assess heart beat.  Cleft lip

COMPLICATIONS DURING PREGNANCY • Hemorrhagic Conditions o Abortion

  



The spontaneous or induces abortion of a pregnancy before viability of the fetus. Viability is defined as 20 – 24 weeks of gestation and a weight of 500 g. Induced – voluntary method of termination. • Factors: o Preserve the health of the mother. o Prevent the birth of an infant with severe genetic defects. o End pregnancy cause by rape or incest. o Economic or social reasons. • Methods o Vacuum aspiration o Pills (drugs)  Mifepristone (RU [roussel u-claf] 486)  Misoprostol (cytotec) – prostaglandin  Methotrexate (cancer drug) Spontaneous Abortion • Commonly known as miscarriage. • Factors: o Chromosomal abnormalities o Faulty implantation o Teratogenic substances o Placental abnormalities o Incompetent cervix o Chronic maternal disease o Maternal infections o Endocrine imbalances • Classification o Threatened  Unexplained bleeding and cramping, cervix is closed and membranes are intact. o Inevitable  Increase bleeding and cramping, the cervix begins to dilate and the membranes may rupture. o Incomplete  Some of the products of conception are expelled; most often the placenta is not expelled; bleeding is heavy and cramping is severe. o Complete  All products of conception are expelled. o Missed  Embryo or fetus dies but is retained; the cervix is closed; if the fetus is not expelled within 6 weeks, disseminated intravascular coagulation may develop. o Habitual  Any of the above occurring in 3 consecutive pregnancies; most commonly the cervix begins to dilate in the 2nd trimester; this is called an incompetent cervix.

Management  Limit activities for 24 – 48 hours  Avoid stress, fatigue, strenuous activity and sexual intercourse if bleeding stops.  Increase rest periods until pregnancy seems to be progressing normally.  Dilatation and curettage or suction evacuation is performed to remove the products of conception from the uterus for inevitable or incomplete abortion.  Blood transfusion may be given depending on the amount of blood loss.  Induction of labor for missed abortion in 12 weeks AOG and D&C for less 12 weeks AOG and below.  Cerclage for habitual abortion caused by incompetent cervix.

Eclampsia • Grand mal seizures with tonic (pronounced muscular contraction) and clonic (alternate contraction and relaxation of muscle) phase. • A client sleeps into a coma from minutes to hours. • Seizures/coma sequence can be repeated one or more time and death may follow. o Chvostek’s sign o Trousseau’s sign  HELLP syndrome • PIH with liver damage • Characterized by HELLP o Hemolysis is caused when intra-arterial lesions develop due to vasospasm causing platelets to aggregate and a fibrin network to be formed; the RBC are forced through the fibrin network and lysis resulting in large drop in hematocrit. o Elevated liver enzymes may be due to microemboli in the vessels of the liver causing ischemia o Low platelet counts result when the platelets are entrapped at the intra-arterial lesions o Results to ischemia and tissue damage o May show signs of hypoglycemia. • Management o Goal: lowers BP, prevent convulsion and deliver a healthy baby o Complete bed rest for client’s mild preeclampsia with increase renal and placental blood flow. o Monitor laboratory data o Caesarian birth o MgSO4 o Hydralazine o Sedative may be given to let the client rest quietly o Oxytocin may be given to induce labor Gestational Diabetes Mellitus o General Information  Chronic disease caused by improper metabolic interaction of carbohydrates, protein, fats and insulin  Interaction of pregnancy and diabetes may cause serious complications of pregnancy  Classifications of Diabetes mellitus: • Type 1: formerly called juvenile-onset or insulindependent diabetes; onset before age 40 • Type 2: formerly called maturity-onset or non-insulindependent; onset after age 40 • Type 3: formerly called gestational; onset during pregnancy; reversal after termination of pregnancy • Type 4: formerly called secondary; occurs after pancreatic infections or endocrine disorder o Significance of Diabetes in pregnancy 



Epigastric pain (last symptom identified before the client moves into eclampsia.

Interaction of estrogen, progesterone, HPL and cortisol raise maternal resistance to insulin (inability to use glucose at the cellular level).  If the pancreas cannot respond by producing additional insulin, excess glucose moves across placenta to fetus, where fetal insulin metabolizes it and acts as growth hormone, promoting macrosomia.  Maternal insulin levels need to be carefully monitored during pregnancy to avoid widely fluctuating levels of blood glucose.  Dose may drop during first trimester, then rise during second and third trimesters.  Higher incidence of fetal anomalies and neonatal hypoglycemia (good control minimizes) o Assessment Findings  Polyuria  Polydipsia  Weight loss  Polyphagia  Elevated glucose levels in blood and urine. Urine tests for elevated blood glucose less reliable in pregnancy. Blood tests (more accurate) used as follows: • 1-hour glucose tolerance test: usually done for screening on all pregnant women 24-28 weeks pregnant. • 3-hour glucose tolerance test: used where results from 1hour GTT> 140 mg/dl. • HbAlc: glycosylated hemoglobin; reflects past  4-12 week blood levels of serum glucose. o Nursing Interventions  Teach client the effects and interactions of diabetes and pregnancy and signs of hyper- and hypoglycemia  Teach client how to control diabetes in pregnancy, advice of changes that need to be made in nutrition and activity patterns to promote normal glucose levels & prevent complications.  Advice client of increased risk of infection and how to avoid it.  Observe and report any signs of preeclampsia  Monitor fetal status throughout pregnancy  Assess status of mother and baby frequently  Monitor carefully fluids; calories, glucose and insulin during labor and delivery  Continue careful observation in post delivery. • Rh incompatibility B. Intrapartal Period • Extends from the beginning of contractions that causes cervical dilatation to the 1st 4 hours after delivery of the newborn and placenta. • Labor o Process by which the fetus and products of conception are expelled as the result of regular, progressive, frequent, strong uterine contractions. o Theories Explaining Onset Of Labor  Uterine Stretch Theory • A hollow organ such as the uterus when full will empty.  Oxytocin Theory • Oxytocin released by the posterior pituitary gland initiates labor. 

Progesterone Deprivation Theory • Contraction initiated when progesterone level are decreased as such at the end of pregnancy.  Prostaglandin Cascade Theory • Labor is initiated due to the production of prostaglandin as a result of interplay between adrenal, fetus and uterus.  Aging Placenta Theory Components of Labor and Delivery  Power • Forces that cause the cervix to open and propel the fetus through the birth canal. • Uterine contraction o Primary power of labor o Characteristics  Involuntary contraction • Spontaneous contraction • Cervix dilatation and effacement of the cervix during the 1st stage of labor • Phases: Increment (gain strength). Acme (peak), Decrement (letting go)  Intermittent Contraction • Description o Frequency o Duration o Intensity o Regularity • Maternal Push o Voluntary beating down efforts o After full dilatation of the cervix o Efforts similar to those of defecation o Contraction of levator ani muscle  Passenger • Refers to the fetus plus the membranes and placenta • Fetal skull and fetal accommodation to passageway affects the labor progress. • Indication of fetal head o Largest part of the body o Common presenting part o Least compressible fetal part  Cranial bones • Frontal – 1 • Parietal – 2 • Temporal – 2 • Occipital – 1 • Sphenoid – 1 • Ethmoid - 1 • Suture line o Intermembranous spores o Allows molding – overlapping of the sutures o Sagittal – 2 parietal o Coronal – parietal and frontal o Lamboidal – parietal and occipital 
