Presumptive Signs and Symptoms:

Presumptive Signs and Symptoms Abrupt cessation of menses - more than 10 days Breast changes Skin pigmentation changes: Chloasma/melasma gravidarum Linea nigra Abdominal striae Nausea and vomiting (morning sickness) Frequency of urination Fatigue

Probable Signs and Symptoms:

Probable Signs and Symptoms Objective findings detected by 12 to 16 weeks of gestation Enlargement of abdomen Hegar's sign Chadwick's sign Goodell's sign Braxton Hicks contractions Ballottement Leukorrhea Quickening Positive hCG - test for pregnancy

Positive Signs and Symptoms:

Positive Signs and Symptoms Fetal heart tones ( FHTs ) usually heard between 16 th and 20 th week of gestation with a fetoscope or the 10 th and 12 th week of gestation with a Doppler stethoscope Fetal movements felt by the examiner (after about 20 weeks gestation) Outlining of the fetal body through the maternal abdomen in the second half of pregnancy Sonographic evidence (after 4 weeks gestation) using vaginal ultrasound. Fetal cardiac motion can be detected by 6 weeks gestation



Duration of Pregnancy:

Duration of Pregnancy Averages 280 days/40 weeks (10 lunar months; 9 calendar months) from the 1st day of LMP Divided into 3 trimesters of slightly more than 13 weeks or 3 calendar months each EDC is calculated by Nägele's rule +7 days, -3 months to LMP McDonald's rule: after 24 weeks' gestation, the fundal height measurement will correspond to the week of gestation plus 2-4 weeks

Changes in the Reproductive Tract :

Changes in the Reproductive Tract


Uterus Enlargement, stretching and marked hypertrophy of existing muscle cells 2° to increased estrogen and progesterone levels Increase in fibrous tissue and elastic tissue; increase in size and number of blood vessels and lymphatics Enlargement and thickening of the uterine wall are most marked in the fundus By the end of 12 weeks, the uterus can be palpated suprapubically The uterus rotates somewhat to the right because of the rectosigmoid colon on the left side of the pelvis

Slide 15:

20 weeks: fundus has reached the level of the umbilicus 36 weeks: fundus has reached the xiphoid process End of 5 th month, the myometrium hypertrophy ends and the walls of uterus become thinner, allowing palpation of the fetus During the last 3 weeks, the uterus descends slightly because of fetal descent into the pelvis Changes in contractility occur - from the first trimester, Braxton Hicks contractions; in latter weeks of pregnancy, contractions become stronger and more regular Progressive increase in uteroplacental blood flow during pregnancy


Cervix Pronounced softening and cyanosis - due to increased vascularity, edema, hypertrophy, and hyperplasia of the cervical glands Operculum - prevents bacteria and other substances from entering and ascending into the uterus Erosions of cervix, common during pregnancy, represent an extension of proliferating endocervical glands and columnar endocervical epithelium Evidence of Chadwick's sign due to the increased vascularity and hyperemia caused by increased estrogen levels


Ovaries Ovulation ceases during pregnancy; maturation of new follicles is suspended One corpus luteum functions during early pregnancy (first 10 to 12 weeks), producing progesterone and small levels of estrogen and relaxin After 8 weeks gestation, the corpus luteum remains the source for the hormone relaxin

Vagina and Outlet:

Vagina and Outlet Increased vascularity, hyperemia , and softening of connective tissue in skin and muscles of the perineum and vulva Vaginal walls prepare for labor: mucosa increases in thickness, connective tissue loosens, and small-muscle cells hypertrophy Vaginal secretions: thick, white, and acidic; pH=3.5 to 6 because of increased production of lactic acid from glycogen in the vaginal epithelium by Lactobacillus acidophilus; prevention of infections Hypertrophy of the structures, along with fat deposits, causes the labia majora to close and cover the vaginal introitus (vaginal opening)

Changes in the Abdominal Wall:

Changes in the Abdominal Wall Striae gravidarum (stretch marks) - reddish, slightly depressed streaks in the skin of abdomen, breast, and thighs (become glistening silvery lines after pregnancy) Linea nigra - line of dark pigment extending from the umbilicus down the midline to the symphysis. Commonly during the first pregnancy, the linea nigra occurs at the height of the uterus. During subsequent pregnancies, the entire line may be present early in gestation. Diastasis recti may occur as muscles (rectus) separate. If severe, a part of the anterior uterine wall may be covered by only a layer of skin, fascia, and peritoneum.

Breast Changes:

Breast Changes Tenderness and tingling occur in early weeks of pregnancy Increase in size by 2 nd month - hypertrophy of mammary alveoli. Veins more prominent, and striae may develop Nipples become larger, more deeply pigmented, and more erectile early in pregnancy Colostrum may be expressed by 2 nd trimester Areolae become broader and more deeply pigmented. Scattered through the areola are glands of Montgomery, which are hypertrophic sebaceous glands.

Metabolic Changes:

Metabolic Changes

Weight gain average:

25 to 35 lb (11.5 to 16 kg) Weight gain average

Water metabolism:

Water metabolism Retains 6-8 L of extra water during the pregnancy Approximately 4-6 L of fluid cross into the extracellular spaces ( hypervolemia ) Normal accumulation of fluid in their legs and ankles at the end of the day - 3 rd trimester (physiologic edema) Sodium retention is usually directly proportional to the amount of water accumulated during the pregnancy Additional sodium is required during pregnancy to meet the need for increased intravascular and extracellular fluid volumes and to maintain a normal isotonic state

Protein Metabolism:

Protein Metabolism The fetus, uterus, and maternal blood are rich in protein At term, fetus and placenta contain 500 g of protein or approximately half of the total protein increase of pregnancy Approximately 500 g more of protein is added to the uterus, breasts, and maternal blood in the form of hemoglobin and plasma proteins

Carbohydrate Metabolism:

Carbohydrate Metabolism Early in pregnancy, the effects of estrogen and progesterone can induce a state of hyperinsulinemia . As pregnancy advances, there is increased tissue resistance coupled with increased hyperinsulinemia Approximately 2% to 3% of all women will develop gestational DM during pregnancy Pregnant women with preexisting DM may experience a worsening of the disease attributed to hormonal changes “sparing” of glucose used by maternal tissues and shunting of glucose to the placenta for use by the fetus HPL , estrogen, progesterone, and cortisol oppose the action of insulin during pregnancy and promote maternal lipolysis

Fat Metabolism:

Fat Metabolism Lipid metabolism during pregnancy causes an accumulation of fat stores, mostly cholesterol, phospholipids, and triglycerides Fat storage occurs before the 30th week of gestation After 30 weeks' gestation, there is no further fat storage, only fat mobilization that correlates with the increased utilization of glucose and amino acids by the fetus. The ratio of low-density proteins to high-density proteins is increased during pregnancy

Nutrient Requirements :

Nutrient Requirements Y

Caloric Requirements:

Caloric Requirements An additional 300 kcal/ dL are required during the 2 nd and 3 rd trimester Caloric expenditure varies throughout pregnancy. There is a slight increase in early pregnancy and a sharp increase near the end of the 1 st trimester, continuing throughout pregnancy. Protein Requirements An additional requirement of 10 g of protein per day is recommended over the nonpregnant intake.

Carbohydrate and Fat Requirements :

Carbohydrate and Fat Requirements Carbohydrates should supply 55% to 60% of calories in the diet and should be in the form of complex carbohydrates, such as whole-grain cereal products, starchy vegetables, and legumes Fat intake should not exceed 30% of the diet. Saturated fats should not exceed 10% of the total calories. Iron Requirements Iron requirements are increased to 20 to 40 mg daily Supplemental iron is valuable and necessary during pregnancy and postpartum During the last half of pregnancy, iron is transferred to the fetus and stored in the fetal liver. This store lasts 3 to 6 months.

Changes in the Cardiovascular System :

Changes in the Cardiovascular System


Heart Diaphragm is progressively elevated during pregnancy; heart is displaced to the left and upward, with the apex moved laterally Heart sounds - exaggerated splitting of the first heart sound; a loud, easily heard third sound Heart murmurs - systolic murmurs are common and usually disappear after delivery

Blood Volume Changes:

Blood Volume Changes Cardiac volume increases by 40% to 50% (1,450 to 1,750 mL ) by 32 weeks' gestation Cardiac output increases by 30% to 50% above normal within the first 13 weeks of pregnancy and reaches a volume of 6 to 7 L/minute by term Femoral venous pressure increases Increased cutaneous blood flow dissipates excess heat Physiologic anemia of pregnancy or physiologic dilutional anemia

Slide 39:

Supine hypotensive syndrome

Blood Pressure Changes:

Blood Pressure Changes During the first half of pregnancy, there is a slight (5 to 10 mm Hg) decrease in systolic and diastolic BP By the third trimester, the BP gradually returns to prepregnancy levels Maternal position influences blood pressure: the highest reading is obtained in the sitting position, the lowest reading is obtained in the left lateral position, and an intermediate reading is obtained in the supine position Maternal blood pressure will also rise with uterine contractions and returns to the baseline level after the uterine contraction is over

Hematologic Changes:

Hematologic Changes Total volume of circulating RBCs increases 18% to 30%; hemoglobin concentration at term averages 12 to 16 g/ dL ; hematocrit concentration at term averages 37% to 47%. WBC count in the 3 rd trimester is 5 to 12,000/ml Pregnancy is a hypercoagulable state due to the increased levels of a number of essential coagulation factors. Average platelet count is 140,000 to 400,000/ mm 3 , which increases the risk to the pregnant woman for venous thrombosis.

Changes in the Respiratory Tract :

Changes in the Respiratory Tract

Slide 44:

Diaphragm is elevated during pregnancy Thoracic cage expands its anteroposterior diameter causing flaring of the ribs Breathing is more diaphragmatic than costal Hyperventilation occurs - increase in respiratory rate, tidal volume increases 30% to 40%, and minute ventilation increases 40% Increased total volume lowers blood partial pressure of carbon dioxide ( Pco 2 ), causing mild respiratory alkalosis that is compensated for by lowering of the bicarbonate concentration

Slide 46:

Increased respiratory rate and reduced Pco 2 are probably induced by progesterone and estrogen Oxygen consumption increases 15% to 20% and as much as 300% in labor This increase leads to increased maternal alveolar and arterial oxygen partial pressure levels. Approximately 60% to 70% of pregnant women experience shortness of breath; unknown cause Nasal stuffiness and epistaxis secondary to vascular congestion caused from the increased estrogen levels

Changes in Renal System :

Changes in Renal System

Slide 49:

When the uterus rises out of the uterine cavity, it rests on the ureters , compressing them at the pelvic brim Glomerular filtration rate ( GFR ) increases 50% by the 2 nd trimester, and the increase persists almost to term Glucosuria may be evident because of the increase in glomerular filtration without an increase in tubular resorptive capacity for filtered glucose Ureters become dilated and elongated during pregnancy because of mechanical pressure

Slide 50:

Excreted protein may be increased due to the increased GFR , but is not considered abnormal until the level exceeds 250 mg/ dL Toward the end of pregnancy, pressure of the presenting part impedes drainage of blood and lymph from the bladder base, typically leaving the area edematous , easily traumatized, and more susceptible to infection.

Changes in GI Tract :

Changes in GI Tract

Slide 53:

Gums may become hyperemic and softened and may bleed easily A localized vascular swelling of the gums may appear ( epulis of pregnancy) Stomach and intestines are displaced upward and laterally by the enlarging uterus. Heartburn ( pyrosis ) is common. Decreased motility, mechanical obstruction by the fetus, and decreased water absorption from the colon leads to constipation Hemorrhoids are common because of elevated pressure in veins below the level of the large uterus and constipation

Slide 54:

Distention and hypotonia of the gallbladder are common, which can cause stasis of bile Decrease in emptying time and thickening of bile, resulting in hypercholesterolemia and gallstone formation Prothrombin time may show a slight increase or be unchanged Peptic ulcer formation or exacerbation is uncommon during pregnancy due to decreased hydrochloric acid (caused by increased estrogen levels The appendix is pushed superiorly

Changes in the Endocrine System :

Changes in the Endocrine System

Slide 57:

APG enlarges slightly; PPG remains unchanged Thyroid is moderately enlarged because of hyperplasia of glandular tissue and increased vascularity BMR increases progressively during normal pregnancy (25%) because of metabolic activity of fetus Level of protein-bound iodine and thyroxine rises sharply and is maintained until after delivery because of increased estrogen and hCG Parathyroid gland size and concentration of parathyroid hormone increase and peak between 15 and 35 weeks

Slide 59:

Adrenal secretions considerably increased - amounts of aldosterone increase as early as the 15th week Pancreas Estrogen, progesterone, cortisol , and hPL decrease the maternal utilization of glucose Cortisol also increases maternal insulin production Insulinase , an enzyme produced by the placenta, deactivates maternal insulin These changes result in an increased need for insulin, and the islets of Langerhans increase their production of insulin

Changes in Integumentary System :

Changes in Integumentary System

Slide 61:

Pigment changes because of MSH ; elevated from the 2 nd month of pregnancy until term Striae gravidarum - slightly depressed streaks in the skin of the abdomen, breasts and thighs Linea nigra - brownish-black line of pigment in the midline of the abdominal skin Chloasma/melasma or “mask of pregnancy” - brownish patches of pigment on the face Angiomas (vascular spider nevis ), minute red elevations on the skin of the face, neck, upper chest, legs, and arms Reddening of the palms ( palmar erythema ) Increased warmth to the skin and increased nail growth

Changes in the Musculoskeletal System :

Changes in the Musculoskeletal System

Slide 64:

Relaxin - increases mobility of sacroiliac, sacrococcygeal , and pelvic joints The center of gravity shifts secondary to increased weight gain, fluid retention, lordosis , and mobile ligaments. This contribute to alteration of maternal posture and back pain Late in pregnancy, aching, numbness, and weakness in the upper extremities may occur because of lordosis and paresthesia , which ultimately produces traction on the ulnar and median nerves Separation of the rectus muscles due to pressure of the growing uterus creates a diastasis recti

Changes in the Neurologic System :

Changes in the Neurologic System

Slide 67:

Mild frontal headaches are common in the 1 st and 2 nd trimester; related to tension or hormonal changes Dizziness is common and is related to vasomotor instability, postural hypotension, or hypoglycemia following long periods of standing or sitting Tingling sensations in the hands are common and are due to excessive hyperventilation, which decreases maternal Pco 2 levels Severe headaches that occur after 20 weeks' gestation and are accompanied by visual changes, elevated blood pressure, proteinuria , and facial edema should be evaluated immediately.

Changes in Hormonal Responses :

Changes in Hormonal Responses

Steroid Hormones:

Steroid Hormones Estrogen: secreted by the ovaries in early pregnancy, but by 7 weeks' gestation over half of the estrogen is secreted by the placenta ensure uterine growth and development, maintenance of uterine elasticity and contractility, maintenance of breast growth and its ductal structures, and enlargement of the external genitalia Progesterone: initially secreted by corpus luteum ; later by placenta suppresses the maternal immunologic response to the fetus and rejection of the trophoblasts helps to maintain the endometrium , inhibits uterine contractility, helps in the development of breast lobules for lactation, stimulates the maternal respiratory center, and relaxes smooth muscle

Placental Protein Hormones:

Placental Protein Hormones hCG : Secreted by the syncytiotrophoblasts ; stimulates the production by the corpus luteum of progesterone and estrogen 2x as high in multiple gestation than in single pregnancy h\levels peak around 10 weeks' gestation (50,000 to 100,000 mIU/mL ) then decrease to 10,000 to 20,000 mIU/mL by 20 weeks' gestation hPL : human chorionic somatomammotropin Produced by the syncytiotrophoblasts of the placenta increases the amount of free fatty acids available to the fetus and decreases the maternal metabolism of glucose allowing for protein synthesis. This allows the fetus to have the needed nutrients when the woman has not or is not eating

Other Hormones:

Other Hormones Prostaglandins: Affect smooth muscle contractility and some potent vasodilators Essential for the cardiovascular adaptation to pregnancy, cervical ripening, and initiation of labor. Relaxin : Secreted by the corpus luteum , decidua and placenta Inhibits uterine activity, decreases the strength of uterine contractions, softens the cervix, and remodels collagen Prolactin : Released from the APG Responsible for sustaining milk protein, casein, fatty acids, lactose, and the volume of milk secretion during lactation

Vaginal Examination

Subsequent Prenatal Assessments:

Subsequent Prenatal Assessments Uterine growth and estimated fetal growth. Fundus at symphysis pubis indicates 12 weeks Fundus at umbilicus indicates 20 weeks Fundal height corresponds with gestational age between 22 and 34 weeks. Fundus at lower border of rib cage indicates 36 weeks Uterus becomes globular, and drop indicates 40 weeks A greater fundal height suggests: Multiple pregnancy. Miscalculated due date. Polyhydramnios (excessive amniotic fluid). Hydatidiform mole (degeneration of villi into grapelike clusters; fetus does not usually develop). Uterine fibroids


Height of Fundus

Slide 89:

A lesser fundal height suggests: Intrauterine fetal growth restriction. Error in estimating gestation. Fetal or amniotic fluid abnormalities. Intrauterine fetal death. SGA FHTs - palpate abdomen for fetal position. Normal - 110 to 160 beats per minute ( bpm ) Weight - major increase in weight occurs during second half of pregnancy; usually between 0.5 lb (0.2 kg)/week and 1 lb (0.5 kg)/week BP- should remain near woman's prepregnant baseline Complete blood count at 28 and 32 weeks' gestation; VDRL - rechecked at 36 to 40 weeks' gestation.

Nursing Interventions :

Nursing Interventions

Minimizing Pain:

Minimizing Pain Use good body mechanics - wear comfortable, low-heeled shoes with good arch support Pelvic rocking exercises Take rest periods with legs elevated Adequate calcium intake may decrease leg cramps Dorsiflex the foot while applying pressure to the knee to straighten the leg for immediate relief of leg cramps Wear a fitted, supportive brassiere Wash breasts and nipples with water only Apply vitamin E or lanolin cream to the breast and nipple area

Minimizing Morning Sickness and Heartburn and Maintaining Adequate Nutrition :

Minimizing Morning Sickness and Heartburn and Maintaining Adequate Nutrition Eat low-fat protein foods and dry carbohydrates (toast, crackers); Eat small, frequent meals, Eat slowly Avoid brushing teeth soon after eating Get out of bed slowly Drink soups and liquids between meals to avoid stomach distention and dehydration Caution against the use of sodium bicarbonate because it results in the absorption of excess Na and fluid retention Avoid offensive foods or cooking odors that may trigger nausea

Slide 104:

Basic food groups with appropriate daily servings. 7 servings of protein-rich foods, including one serving of a vegetable protein 3 servings of dairy products or other calcium-rich foods 7 servings of grain products 2 or more servings of vitamin C-rich vegetable or fruit 3 servings of other fruits and vegetables 3 servings of unsaturated fats 2 or more servings of other fruits and vegetables If the woman is a vegetarian, inform her of appropriate intake. Assess type of vegetarian and food intake Recommend iron and folic acid supplements

Slide 105:

Average weight gain: 25-35 lb (11-16 kg). 2-5 lb (0.9-2.3 kg) gained in the 1 st trimester; 1 lb (0.5 kg)/wk for the remainder of the gestation Average weight gain Obese: 15 lb (6.8 kg) Adolescent: 5 lb more than for adult women if within 2 years of starting menses Multiple pregnancy: 35-45 lb (15.9-20.5 kg) Underweight: 28-40 lb (12.7-18.1 kg) Limit the use of caffeine; Eliminate alcohol and smoking Risk of spontaneous abortion, fetal death, low birth weight, and neonatal death Ingesting any drug during pregnancy may affect fetal growth; discuss with health care provider

Minimizing Urinary Frequency and Promoting Elimination:

Minimizing Urinary Frequency and Promoting Elimination Limit fluid intake in the evening Void before going to bed Void after meals Void when feeling the urge and after sexual intercourse Wear loose-fitting cotton underwear Cranberry or blueberry juice to help prevent UTIs Avoid caffeine

Avoiding Constipation:

Avoiding Constipation Increase fluid intake to at least 8 glasses of water/day; 1-2 quarts of fluid per day Eat foods high in fiber daily Establish regular patterns of elimination Daily exercise (walking) Avoid OTC laxatives; bulk-forming agents may be prescribed if indicated

Maintaining Tissue Integrity:

Maintaining Tissue Integrity Take frequent rest periods with legs elevated Wear support stockings and loose-fitting clothing for leg varicosities Rest periodically with a small pillow under the buttocks to elevate the pelvis for vulvar varicosities Avoid constipation, apply cold compresses, take sitz baths, and use topical anesthetics , such as Tucks, for the relief of anal varicosities ( hemorrhoids ) Varicosities will totally or greatly resolve after delivery

Reducing Anxiety and Fear and Promoting Preparation for Labor, Delivery, and Parenthood :

Reducing Anxiety and Fear and Promoting Preparation for Labor, Delivery, and Parenthood Discuss knowledge, perceptions, cultural values, and expectations of the labor and delivery process Provide information on childbirth education classes and sibling and grandparent preparation Tour of the birth facility Coping and pain control techniques for labor and birth Common procedures during labor and birth

Slide 111:

Guidelines for coming to the birth facility Discuss perceptions and expectations of parenthood and their “idealized child” Discuss the infant's sleeping, eating, activity, and response patterns for the first month of life Physical preparations for the infant, such as a sleeping space, clothing, feeding, changing, and bathing equipment Plans for returning to work and childcare arrangements Planning time for themselves and each other apart from the newborn Attend baby care, breast-feeding, and parenting classes Answer any questions the woman/couple may have

Enhancing Role Changes:

Enhancing Role Changes Discussion of feelings and concerns regarding the new role of mother and father Emotional support to the woman/couple regarding the altered family role Physiologic causes for changes in sexual relationships (fatigue, loss of interest, discomfort from advancing pregnancy); Some women experience heightened sexual activity during the 2 nd trimester There are no contraindications to intercourse or masturbation to orgasm provided the woman's membranes are intact, there is no vaginal bleeding, and she has no current problems or history of premature labor Female superior or side-lying positions are usually more comfortable in the latter half of pregnancy

Minimizing Fatigue:

Minimizing Fatigue Teach the reasons for fatigue, and plan a schedule for adequate rest Fatigue in the 1 st trimester is due to increased progesterone and its effects on the sleep center. Fatigue in the 3 rd trimester is due mainly to carrying increased weight of the pregnancy About 8 hours of rest are needed at night Inability to sleep may be due to excessive fatigue during the day In the latter months of pregnancy, sleep on the side with a small pillow under the abdomen Frequent 15-30 minute rest periods during the day Work while sitting with legs elevated Avoid standing for prolonged periods, especially during the 3 rd trimester.

Slide 115:

To promote placental perfusion, the woman should lie on left lateral position; either side is acceptable Plan for adequate exercise Keep with the prepregnancy pattern and type of exercise Avoid activities or sports that have a risk of bodily harm (skiing, snowmobiling, ice skating, inline skating, horseback riding) Endurance during exercise may be decreased Exercise classes for pregnant women that concentrate on toning and stretching have resulted in enhanced physical condition, increased self-esteem, and greater social support as a result of being in the exercise group.

Community and Home Care Instructions :

Oxytocin as a High-Alert Medication: Implications for Perinatal Patient Safety:

Oxytocin as a High-Alert Medication: Implications for Perinatal Patient Safety Kathleen Rice Simpson PhD, RNC, FAAN and G. Eric Knox, MD MCN , The American Journal of Maternal/Child Nursing, January/February 2009, Volume 34, Number 1, Pages 8 - 15 In 2007, the Institute for Safe Medication Practices added intravenous (IV) oxytocin to their list of high-alert medications. Errors that involve IV oxytocin administration for labor induction or augmentation are most commonly dose related and often involve lack of timely recognition and appropriate treatment of excessive uterine activity (tachysystole).

Slide 122:

Other types of oxytocin errors involve mistaken administration of IV fluids with oxytocin for IV fluid resuscitation during nonreassuring (abnormal or indeterminate) fetal heart rate patterns and/or maternal hypotension and inappropriate elective administration of oxytocin to women who are less than 39 completed weeks' gestation. Oxytocin medication errors and subsequent patient harm are generally preventable. The perinatal team can develop strategies to minimize risk of maternal-fetal injuries related to oxytocin administration consistent with safe care practices used with other high-alert medications.

Oral Intake During Labor: A Review of the Evidence:

Oral Intake During Labor: A Review of the Evidence Nancy C. Sharts-Hopko PhD, RN, FAAN MCN , The American Journal of Maternal/Child Nursing, July/August 2010, Volume 35, Number 4, Pages 197 - 203 Fasting in labor became standard policy in the United States after findings of a 1946 study suggested that pulmonary aspiration during general anesthesia was an avoidable risk. Today general anesthesia is rarely used in childbirth and its associated maternal mortality usually results from difficulty in intubation.

Slide 124:

Research from the United States, Australia, and Europe suggests that oral intake may be beneficial, and adverse events associated with oral intake such as vomiting and prolongation of labor do not seem to be associated with alterations in maternal or infant outcomes. The World Health Organization recommends that healthcare providers should not interfere in women's eating and drinking during labor when no risk factors are evident. Nurses in intrapartum settings are encouraged to work in multidisciplinary teams to revise policies that are unnecessarily restrictive regarding oral intake during labor among low-risk women.

Overcoming the Challenges: Maternal Movement and Positioning to Facilitate Labor Progress:

Overcoming the Challenges: Maternal Movement and Positioning to Facilitate Labor Progress Elaine Zwelling PHD, RN, LCCE , FACCE MCN , The American Journal of Maternal/Child Nursing, March/April 2010, Volume 35, Number 2, Pages 72 - 78 The benefits of maternal movement and position changes to facilitate labor progress have been discussed in the literature for decades. Recent routine interventions such as amniotomy, induction, fetal monitoring, and epidural anesthesia, as well as an increase in maternal obesity, have made position changes during labor challenging.

Slide 126:

The lack of maternal changes in position throughout labor can contribute to dystocia and increase the risk of cesarean births for failure to progress or descend. This article provides a historical review of the research findings related to the effects of maternal positioning on the labor process and uses six physiological principles as a framework to offer suggestions for maternal positioning both before and after epidural anesthesia.
