OBSTETRICAL NURSING
EXCERPT Birth usually feels like a steamy kitchen—similar to holiday preparations, except the smells are different. The smell of sweat is more acrid, there are some fetid odors, there is the smell and steam rising from blood. The air is thick, pungent, fertile. It is hard not to be reminded of fresh straw and night stars. There is near and heady promise. ~ Penny Armstrong & Sheryl Feldman, A Midwife's Story ~ Overview of Philippine Obstetrics Latin origin: Obstetrix Midwife FROM WOMB TO TOMB

UTERUS Hollow, pear-shaped fibromuscular organ Functions: Organ of menstruation Site of implantation Retainment and nourishment of product of conception Consists of 3 parts: Corpus Isthmus Cervix Composed of 3 muscle layers: Perimetrium Myometrium Endometrium FALLOPIAN TUBES 4 inches long from each side of the fundus Peristaltic movements in the tubes cause the transport of the mature ovum from the ovaries to the uterus. AMPULLA – widest part at the outer third or outer half where fertilization takes place OVARIES Sex glands Produce and expel ova or egg per cycle Produce estrogen and progesterone Estrogen Inhibits production of FSH (Follicle Stimulating Hormone) Causes hypertrophy of Myometrium Stimulates growth of the ductile structures in the Breasts Increases quantity and pH of the cervical mucus causing it to become thin and watery Progesterone Inhibits production of LH (Luteinizing Hormone) Facilitates transport of the fertilized ovum through the fallopian tube Increases endometrial tortousity. Inhibit uterine and gastrointestinal motility. Decreases muscle tone of the urinary tract Increase musculoskeletal motility Decreases renal threshold for lactose and dextrose. Causes fluid retention. Increases basal fibrinogen levels thus decreasing hematocrit and hemoglobin levels. Increases basal body temperature after ovulation.

REPRODUCTIVE CHANGES DURING PREGNANCY
Ovaries Increased vascularity Corpus luteum persists until the 12th week of pregnancy after which it is taken over by the placenta. Uterus Pear-shaped Size enlarges compatible with age of gestation Braxton Hicks contractions Structural changes include: Changes in the endometrium Changes in the myometrium Increased blood supply Formation of the lower uterine segment With onset of labor, contractions are regular synchronous with fundal dominance. Cervix GOODELL’S SIGN Increased mucus secretion of the cervical glands.

______________________________________________________________

Mucus accumulates within cervical canal that provides a barrier against infections. Vagina Increased in length, distensibility Increased vascularity CHADWICK’S SIGN Increased shedding of the glycogen rich squamous cell resulting in increased whitish, creamy, highly acid vaginal secretion. Breasts Enlargement, tenderness or pain on slight pressure Darkening of primary areola, fluid expressed from the nipple Colostrum Cardiovascular Changes during pregnancy Increase in heart rate Increase in cardiac output about 30-50% 4 periods where there is increase in cardiac output: On the 28th week of gestation During labor Immediately postpartum During 1st week of puerperium Respiratory Changes during pregnancy Increased estrogen causes increased vascularization of upper respiratory tract Progesterone causes respiratory alkalosis compensated by mild metabolic acidosis. Gastro-intestinal Changes during pregnancy Smooth muscle atony and decreased tone of lower esophageal sphincter, causing esophageal regurgitation. Renal Changes during pregnancy Increase in renal pelvis and ureter called “physiologic hydroureter of pregnancy” more on the right side. Endocrine Changes during pregnancy Anterior Pituitary gland hypertrophies with increased activity, posterior lobe increases production of oxytocin necessary for contraction next to term. Normal ovarian function is suspended, corpus luteum activity exists only until 12th week when placenta replaces its role for secretion of hormones. Thyroid gland has increased vascularity, with hyperplasia and enhanced functioning. Hypertrophy and hyperplasia of parathyroid gland also occurs with increased activity to provide adequate amount of calcium to fetus and mother. HCG HPL Hematologic Changes during pregnancy Increased blood volume due to increased plasma volume gradually happening at the end of first trimester and stays high throughout the pregnancy. Increase in blood coagulation factors, increased fibrinogen levels, increase in plasminogen levels and fibrin degradation products. Increased plasma iron binding capacity. Total iron requirement for pregnancy is one gram or 6-7mg per day. Maternal Metabolism In Pregnancy Weight gain of 25-35lbs First trimester Second trimester Third trimester - average of 14 oz or 1 lb/week

SIGNIFICANT MEASUREMENTS AND ESTIMATES
Age of Gestation Nägele's Rule - estimates expected date of confinement (EDC). McDonald’s Method – AOG in months. Measure distance from symphysis pubis to the top of uterine fundus designated as fundal height in centimeters (cm). ESTIMATING FETAL GROWTH MC DONALD’S RULE: •Note fundic height •Between 20 to 31st week of pregnancy: height (symphisis to fundus) in cms in equal to the AOG in weeks •Usually inaccurate at the 3rd trimester •Over symphisispubis : 12th week

______________________________________________________________

•Umbilicus: 20th week •Xiphoid process: 36 weeks Age of Gestation Bartholomew’s – AOG is estimated by the position of uterus in the abdominal cavity. Done thru palpation. Length of Fetus in Centimeters Haase’s Rule • During first half of pregnancy – square the number of the month • Second half of pregnancy – multiply the month by five (5)

ESTIMATING WEIGHT OF FETUS IN GRAMS
Johnson’s Rule - Formula – “n multiplied by k” • “k” – constant, it is always 155 • “n” – 11 if fetus is not yet engaged / 12 if fetus is already engaged LEOPOLD’S MANEUVER LM1 ( Fundal grip) •What fetal pole or part occupies the fundus? –BREECH : irregular, nodular –CEPHALIC : round LM2 ( Umbilical grip) •Which side is the fetal back? –Back : linear, convex –Small Parts : numerous nodulation LM3: (PAWLIC’s grip) •What fetal lies above the pelvic inlet? –Head engaged or not. LM4 : (Pelvic Grip) •Which side is the cephalic prominence? –Cephalic prominence –Flexion –Extension

Maternal age Maternal height Weight Social factors OB HISTORY (high risk) •Multiparity •PROM, IUGR •Premature labor •Macrosomia •Multiple pregnancy •AF abnormalities •UTI, DM, HPN •Uterine/ ovarian diseases thyroid disease PTB Previous CS Abnormal presentations Placental abn.

URINE EXAMINATION
Biological Tests •The presence of HCG in the urine will cause hemorrhagic reaction on the ovaries and testes of the animal. Progesterone Withdrawal Test • Negative result – menstruation within 10-15 days • Positive result – No menstruation after taking pills Urinary Pregnancy Tests • HCG (Human Chorionic Gonadotrophin)

______________________________________________________________

Urine Examination The night before procedure: no water after 8 pm – to concentrate urine to be collected. Morning: collect first morning urine, midstream in a clean dry container. If urine is to be tested more than one hour after collection: refrigerate since HCG is unstable on room temperature. DM SCREENING Pregnancy is diabetogenic due to impairment of peripheral insulin action as a consequence of the action of PLACENTAL LACTOGENS, ESTROGENS and PROGESTERONE Insulin does not cross the placenta fetal hyperglycemia Criteria for the diagnosis of Gestational DM (OGTT) Usually at the 2nd trimester (24th to 28th week) 50 g OGCT if>130mg/dl in 1 hr proceed to 3 hr 100g OGTT after an overnight fast •OGTT: then plasma glucose is measured hourly

ASSESSING FETAL WELL BEING

CRITICAL FACTORS IN LABOR
Birth Passageway The true pelvis and soft tissues of the cervix, vagina, and the pelvic floor form the birth passageway. The true pelvis is divided into three sections: the inlet, the pelvic cavity (midpelvis), and the outlet. Birth Passageway The four classic types of pelvises are Gynecoid Android Arthropoid Platypelloid Birth Passenger (Fetus) The Fetal Head Fetal Attitude Fetal Lie Fetal Presentation Fetal Position. Fetal Head The fetal head is composed of bony parts, which can either hinder childbirth or make it easier. Once the head (the least compressible and largest part of the fetus) has been born, the birth of the rest of the body is rarely delayed. The fetal skull has three major parts: the face the base of the skull (cranium) the vault of the cranium (roof). The bones of the face and cranial base are well fused and essentially fixed. The base of the cranium is composed of the two temporal bones, each with a sphenoid bone and an ethmoid bone. The bones composing the vault are the two frontal bones, the two parietal bones, and the occipital bone

______________________________________________________________

Frontal (mitotic) suture: Sagittal suture: Coronal sutures: Lambdoidal suture: The cranial bones overlap under pressure of the powers of labor and the demands of the unyielding pelvis. This overlapping is called MOLDING The intersection of several cranial sutures forms an irregular space that is enclosed by a membrane and called a FONTANELLE. The greater, or anterior, fontanelle (bregma) The lesser, or posterior, fontanelle •Following are several other important landmarks of the fetal skull: –Mentum: –Sinciput: –Vertex: –Occiput: Fetal Attitude •Fetal attitude refers to the relation of the fetal body parts to one another. •The normal attitude of the fetus is termed general flexion Fetal Lie Relationship of the long, or cephalocaudal, axis (spinal column) of the fetus to the long, or cephalocaudal, axis of the mother. The fetus may assume either a longitudinal (vertical) transverse (horizontal) Fetal Presentation •Refers to the body part of the fetus that enters the maternal pelvis first • determined by fetal lie •Fetal presentation may be: –cephalic (head first) –breech (buttocks or feet first) –shoulder. Fetal Presentation The most common presentation is Cephalic. Malpresentations. Breech and shoulder presentations Fetal Presentation

CEPHALIC PRESENTATION
Vertex Presentation when the presenting part is the occiput, the presentation is noted as vertex. Most common type of presentation. The smallest diameter of the fetal head (suboccipitobregmatic) presents to the maternal pelvis Sinciput Presentation The fetal head is partially flexed. The occipitofrontal diameter presents to the maternal pelvis The top of the head is the presenting part Brow Presentation. The fetal head is partially extended. The occipitomental diameter, the largest anteroposterior diameter, is presented to the maternal pelvis Face presentation The fetal head is hyperextended (complete extension). The submentobregmatic diameter presents to the maternal pelvis The face is the presenting part.

______________________________________________________________

Breech Presentation the lower extremities or buttocks. classified according to the attitude of the fetus's hips and knees. In all variations of the breech presentation the sacrum (the bone on the buttocks that is felt when palpating) is the landmark. Complete Breech The fetal knees and hips are both flexed, the thighs are on the abdomen, and the calves are on the posterior aspect of the thighs. The buttocks and feet of the fetus present to the maternal pelvis. Frank Breech The fetal hips are flexed, and the knees are extended. The buttocks of the fetus present to the maternal pelvis. Footling Breech The fetal hips and legs are extended. The feet of the fetus present to the maternal pelvis. In a single footling one foot presents; in a double footling both feet present. Shoulder Presentation When the fetal shoulder is the presenting part, the fetus is in a transverse lie and the acromion process of the scapula is the landmark. Relationship of Maternal Pelvis and Presenting Part Engagement Engagement of the presenting part occurs when the largest diameter of the presenting part reaches or passes through the pelvic inlet. The intertrochanteric diameter (transverse diameter between the right and left trochanter) is the largest to pass through the inlet in a breech presentation. Engagement The presenting part is said to be floating (or ballottable) when it is freely movable above the inlet. When the presenting part begins to descend into the inlet, before engagement has truly occurred, it is said to be dipping into the pelvis Station Relationship of the presenting part to an imaginary line drawn between the ischial spines of the maternal pelvis. In a normal pelvis the ischial spines mark the narrowest diameter through which the fetus must pass. The ischial spines as a landmark have been designated as zero station.

FETAL POSITION
Refers to the relationship of the landmark on the presenting fetal part to the anterior, posterior, or sides (right or left) of the maternal pelvis. The landmarks Occiput, Mentum, Sacrum Acromion Scapula. In summary, three notations are used to describe the fetal position: 1. Right (R) or left (L) side of the maternal pelvis 2. The landmark of the fetal presenting part: occiput (O), mentum (M), sacrum (S), or acromion (scapula[Sc]) process (A) 3. Anterior (A), posterior (P), or transverse (T), depending on whether the landmark is in the front, back, or side of the pelvis The fetal position influences labor and birth.

______________________________________________________________

The most common fetal position is occiput anterior. Malpositions. Physiologic Forces of Labor •The primary force is uterine muscular contractions, •The secondary force is the use of abdominal muscles CONTRACTIONS Uterine contractions are rhythmic tightenings and shortenings of the uterine muscles during labor. Each contraction has three phases: (1) increment, (2) acme, (3) decrement, •When describing uterine contractions during labor, •intensity •Frequency •Duration Intensity refers to the strength of the uterine contraction during acme. In most instances the intensity is estimated by palpating the contraction, but it may be measured directly with an intrauterine catheter attached to an electronic fetal monitor. When estimating intensity by palpation, the nurse determines whether it is mild, moderate, or strong by judging the amount of indentability of the uterine wall during the acme of a contraction. Bearing down. The combined involuntary pressure of the uterine contractions and the voluntary muscle contractions of the abdomen force the fetus toward the outlet so birth can occur. Possible Causes of Labor Onset

Labor usually begins between the 38th and the 42nd week of gestation, when the fetus is mature and ready for birth. •PROGESTERONE WITHDRAWAL HYPOTHESIS –Progesterone produced by the placenta relaxes uterine smooth muscle by interfering with conduction of impulses from one cell to the next. (Challis, 2004). PROSTAGLANDIN HYPOTHESIS preterm labor may be stopped by using an inhibitor of prostaglandin synthesis such as indomethacin (Challis, 2004). •CORTICOTROPIN-RELEASING HORMONE HYPOTHESIS –CRH levels are elevated in multiple gestations. Finally, CRH is known to stimulate the synthesis of prostaglandin F and prostaglandin E by amnion cells (Vogel, Thorsen, Currey et al., 2005). •ROLE of ESTROGEN –Estrogen is known to stimulate uterine muscle contractions to permit softening, stretching, and eventual thinning of the cervix. Myometrial Activity In true labor the uterus divides into two portions. This division is known as the physiologic retraction ring. With each contraction, the muscles of the upper uterine segment shorten and exert a longitudinal traction on the cervix, causing effacement. In primigravidas effacement usually precedes dilatation. The uterine muscle remains shorter and thicker and does not return to its original length. This phenomenon is known as brachystasis. The uterus elongates with each contraction, decreasing the horizontal diameter. The cervical os and cervical canal widen from less than 1 cm to approximately 10 cm, allowing birth of the fetus.

______________________________________________________________

Premonitory Signs of Labor Lightening describes the effects that occur when the fetus begins to settle into the pelvic inlet (engagement) •the woman may notice the following –Leg cramps or pains –Increased pelvic pressure –Increased venous stasis, –Increased urinary frequency –Increased vaginal secretions BRAXTON HICKS CONTRACTIONS–the irregular, intermittent contractions that have been occurring throughout the pregnancy CERVICAL CHANGES. This softening of the cervix, called ripening, is under the influence of hormonal factors.

BLOODY SHOW With softening and effacement of the cervix, the mucous plug is often expelled a sign of impending labor, usually within 24 to 48 hours. RUPTURE OF MEMBRANES If membranes rupture and labor does not begin spontaneously within 12 to 24 hours, labor may be induced to avoid infection. If engagement has not occurred, the danger exists that the umbilical cord may be expelled with the fluid (prolapsed cord). SUDDEN BURST OF ENERGY Some women report a sudden burst of energy approximately 24 to 48 hours before labor. The cause of the energy spurt is unknown. Differences Between True Labor and False Labor STAGES OF LABOR AND BIRTH First Stage The first stage begins with the beginning of true labor and ends when the cervix is completely dilated at 10 cm. First stage (Latent phase) Begins with the onset of regular contractions. Nullipara: averages 8.6 hours Multiparas: averages 5.3 hours ACTIVE PHASE Cervix dilates from about 4 to 7 cm. Fetal descent is progressive. Cervical dilatation Nulliparas 1.2 cm per hour Multiparas 1.5 cm per hour TRANSITION PHASE Nulliparas should not be longer than 3 hour Multiparas at least 1 hour Cervical dilatation slows as it progresses from 8 to 10 cm and the rate of fetal descent increases. Descent nulliparas at least 1 cm per hour and multiparas 2 cm per hour Second Stage The second stage of labor begins when the cervix is completely dilated (10 cm) and ends with birth of the infant. Primigravida: 2 hours Multiparas: average 15 minutes < 20 hours <14 hours

•As the fetal head descends, the woman has the urge to push. •Crowning occurs

POSITIONAL CHANGES OF THE FETUS
For the fetus to pass through the birth canal, the fetal head and body must adjust to the maternal pelvis by certain positional changes. These changes are called cardinal movements or mechanisms of labor. Descent Descent is thought to occur because of four forces: (1) pressure of the amniotic fluid, (2) direct pressure of the fundus of the uterus on the breech of the fetus, (3) contraction of the abdominal muscles, and (4) extension and straightening of the fetal body. Flexion Flexion occurs as the fetal head descends and meets resistance from the soft tissues of the pelvis, the musculature of the pelvic floor, and the cervix. As a result of the resistance, the fetal chin flexes downward onto the chest. Internal Rotation The fetal head must rotate to fit the diameter of the pelvic cavity, which is widest in the anteroposterior diameter. As the occiput of the fetal head meets resistance from the levatorani muscles and their fascia, the occiput rotates from left to right, and the sagittal suture aligns in the anteroposterior pelvic diameter. Extension The resistance of the pelvic floor and the mechanical movement of the vulva opening anteriorly and forward assist with extension of the fetal head as it passes under the symphysis pubis. With this positional change the occiput, then brow and face, emerge from the vagina. External Rotation As the shoulders rotate to the anteroposterior position in the pelvis, the head is turned farther to one side (external rotation). Expulsion After the external rotation and through expulsive efforts of the laboring woman, the anterior shoulder meets the undersurface of the symphysis pubis and slips under it. As lateral flexion of the shoulder and head occurs, the anterior shoulder is born before the posterior shoulder. The body follows quickly. Third Stage The third stage of labor is defined as the period of time from the birth of the infant until the completed delivery of the placenta. SIGNS OF PLACENTAL SEPARATION These signs are a globular-shaped uterus a rise of the fundus in the abdomen a sudden gush or trickle of blood further protrusion of the umbilical cord out of the vagina. PLACENTAL DELIVERY •A placenta is considered to be retained if more than 30 minutes have elapsed from completion of the second stage of labor. PLACENTAL SEPARATION •Types of placental delivery •Schultze mechanism •Duncan mechanism The Newborn Physiologic Response of the Newborn The newborn period Neonatal transition During this period, the newborn adjusts from intrauterine to extrauterine life.

RESPIRATORY ADAPTATIONS
FETAL LUNG DEVELOPMENT At 20 to 24 weeks, alveolar ducts begin to appear, followed by primitive alveoli at 24 to 28 weeks. Type I cells (structures necessary for respiratory gas exchange) and Type II cells (structures that provide for the synthesis and storage of surfactant) RESPIRATORY ADAPTATIONS At 28 to 32 weeks of gestation the number of type II cells increases further, and peaks at about 35 paralleling late fetal lung development. The peak production of lecithin corresponds closely to the marked decrease in incidence of idiopathic respiratory distress syndrome RESPIRATORY ADAPTATIONS Initiation of Breathing 1. Pulmonary ventilation must be established through lung expansion following birth. 2. A marked increase in the pulmonary circulation must occur. So begins the transition from a fluid-filled environment to an air-breathing, independent, extrauterine life. MECHANICAL EVENTS Approx 80 to 110 mL of fluid remains in the respiratory passages of a normal term fetus at the time of birth. “Thoracic squeeze” the process of labor is primarily responsible for the initial movement of lung fluid out of the lungs (Polin et al., 2004). RESPIRATORY ADAPTATIONS Newborns may have problems clearing the fluid in the lungs and beginning respiration for a variety of reasons: • The lymphatic system may be underdeveloped, thus decreasing the rate at which the fluid is absorbed from the lungs. • Complications that occur before or during labor and birth can interfere with adequate lung expansion, causing failure to decrease pulmonary vascular resistance, resulting in decreased pulmonary blood flow. RESPIRATORY ADAPTATIONS CHEMICAL STIMULI The first breath is the natural result of normal vaginal birth with cessation of placental gas exchange when the cord is clamped. THERMAL STIMULI Excessive cooling may result in profound respiratory depression and evidence of cold stress. SENSORY STIMULI A number of physical and sensory influences help respiration begin. They include the numerous tactile, auditory, and visual stimuli of birth. RESPIRATORY ADAPTATIONS Factors Opposing the First Breath (1) alveolar surface tension; (2) viscosity of lung fluid within the respiratory tract (3) lung compliance. RESPIRATORY ADAPTATIONS Obligate nose breather. Respiratory rates of 60 to 70 bpm Watch-out for dyspnea, cyanosis, or nasal flaring and expiratory grunting occur or any increased use of the intercostal muscle

______________________________________________________________

CARDIOVASCULAR ADAPTATIONS Five major areas of change in cardiopulmonary adaptation are: 1. 2. 3. 4. 5. Increased aortic pressure and decreased venous pressure. Increased systemic pressure and decreased pulmonary artery pressure. Closure of the foramen ovale. Closure of the ductusarteriosus. Closure of the ductusvenosus.

HEART RATE The average resting heart rate in the first week of life is 120 to 160 bpm (Thureen et al., 2005). Auscultation of Apical pulse. Peripheral pulses of all extremities Capillary refill should be less than 2 to 3 secs BLOOD PRESSURE The blood pressure tends to be highest immediately after birth, Blood pressure values during the first 12 hours of life vary with the birth weight. The mean blood pressure is 5 to 55 mm Hg (Thureen et al., 2005) HEMATOPOIETIC ADAPTATIONS After birth, the increases in oxygen saturation and arterial oxygen levels shut off the production of erythropoietin. Hemoglobin rise 1 to 2 g/dL above fetal levels placental transfusion, low oral fluid intake, and diminished extracellular fluid volume HEMATOPOIETIC ADAPTATIONS physiologic anemia of infancy. Neonatal RBCs have a lifespan of 80 to 100 days Leukocytosis is a normal finding because the stress of birth stimulates increased production Blood volume of the term infant is estimated to be 80 mL/kg of body weight. 1. Delayed cord clamping and the normal shift of plasma to the extravascular spaces. 2. Gestational age. 3. Prenatal or perinatal hemorrhage. 4. Site of the blood sample TEMPERATURE REGULATION Newborn requires higher environmental temperatures to maintain a neutral thermal environment. Temperature regulation is the maintenance of thermal balance by losing heat to the environment at a rate equal to heat production Thermoregulation in the newborn is closely related to the rate of metabolism and oxygen consumption. Several newborn characteristics affect establishment of thermal stability. The newborn has less subcutaneous fat Blood vessels of the newborn are closer to the skin The flexed posture of the term infant decreases the surface area exposed Size and age affect the establishment of an NTE Heat Loss Two major routes of heat loss: 1. from the internal core of the body to the body surface and 2.from the external body surface to the environment. The transfer is accomplished through an increase in oxygen consumption, depletion of glycogen stores, and metabolizing of brown fat. Heat loss from the body surface to the environment takes place by four avenues Convection Radiation Evaporation Conduction

______________________________________________________________

Heat Production (Thermogenesis) increased basal metabolic rate, muscular activity, and chemicalthermogenesis (also called nonshiveringthermogenesis [NST]) (Polin et al., 2004). HEPATIC ADAPTATION Iron Storage and Red Blood Cell Production Total body Hgb content and length of gestation last until 5 months of age. Carbohydrate Metabolism At term the newborn's cord blood glucose is 70% to 80% of the maternal blood glucose level (Kalhan&Parimi, 2006). Glucose is the main source of energy in the first 4 to 6 hours after birth (Kalhan&Parimi, 2006) Conjugation of Bilirubin Total serum biliconjugated (direct) and unconjugated (indirect) bilirubin. Unconjugated (indirect) bilirubin not in an excretable form and is a potential toxin. crosses the placenta to be excreted Total bilirubin at birth is less than 3 mg/dL The newborn liver has relatively less metabolic and enzymatic activity decreases the liver's ability to conjugate bilirubinincreases susceptibility to jaundice. Physiologic Jaundice Maisels (2005) describes six factors—several of which can also be related to pathologic events—whose interactions may give rise to physiologic jaundice: 1. Increased amounts of bilirubin delivered to the liver. 2. Defective uptake of bilirubin from the plasma. 3. Defective conjugation of the bilirubin 4. Defect in bilirubin excretion 5. Inadequate hepatic circulation. 6. Increased reabsorption of bilirubin from the intestine About 50% of full-term and 80% of preterm newborns exhibit physiologic jaundice on about the second or third day after birth. The signs of physiologic jaundice appear after the first 24 hours postnatally. Peak bilirubin levels are reached between days 3 and 5 in the full-term infant and between days 5 and 7 in the preterm infant. Several newborn care procedures will decrease the probability of high bilirubin levels: Maintain the newborn's skin temperature at 36.5C (97.8F) or above, because cold stress results in acidosis. Monitor stool for amount and characteristics. Encourage early feedings to promote intestinal elimination and bacterial colonization and to provide caloric and protein intake necessary for the formation of hepatic binding proteins. If jaundice becomes apparent, nursing care is directed toward keeping the newborn well hydrated and promoting intestinal elimination. In breast milk jaundice, the bilirubin begins to rise after the first week of life, when physiologic jaundice is waning. The level peaks at 5 to 10 mg/dL at 2 to 3 weeks of age and declines over the first several months of life (Maisels, 2005). The absence of normal intestinal flora needed to synthesize vitamin K in the newborn gut results in low levels of vitamin K and creates a transient blood coagulation alteration GASTROINTESTINAL ADAPTATIONS The full-term newborn has adequate intestinal and pancreatic enzymes to digest most simple carbohydrates, fat, and proteins. Lactose is the primary carbohydrate in the breastfeeding newborn and is generally easily digested and well absorbed. Adequate digestion and absorption are essential for newborn growth and development. Caloric intake is often insufficient for weight gain until the newborn is 5 to 10 days old. A shift of intracellular water to extracellular space and insensible water loss account for the 5% to 10% weight loss.

Term newborns normally pass meconium within 8 to 24 hours of life—and almost always within 48 hours. Meconium Transitional Stool of breastfeeding

URINARY ADAPTATIONS
Kidney Development and Function Certain physiologic features of the newborn's kidneys 1. The term newborn's kidneys have a full complement of functioning nephrons by 34 to 36 weeks of gestation. 2. The glomerular filtration rate of the newborn's kidneys is low 3. The juxtamedullary portion of the nephron has limited capacity to reabsorb HCO3 and H and concentrate urine. The ability to concentrate urine fully is attained by 3 months of age Concentrating and dilutional limitations of renal function are important considerations in monitoring fluid therapy to avoid dehydration and overhydration.

IMMUNOLOGIC ADAPTATIONS
Three major types of immunoglobulins IgG, IgA, and IgM. active acquired immunity. passive acquired immunity Because the maternal immunoglobin is transferred primarily during the third trimester, In general, newborns have maternally induced immunity to: tetanus, diphtheria, smallpox, measles, mumps, poliomyelitis

IMMUNOLOGIC ADAPTATIONS
Elevated levels of IgM at birth may indicate placental leaks or, more commonly, fetal antigenic stimulation in utero. Syphilis TORCH syndrome (toxoplasmosis, rubella, cytomegalovirus, or herpes virus hominis type 2 infection). IgA appears to provide protection mainly on secreting surfaces such. Colostrum has very high levels of IgA. Begin producesecretoryIgA in their intestinal mucosa at about 4 weeks after birth. Newborn Care The two broad goals of nursing care during this period are: (1) to promote the physical well-being of the newborn, and (2) to support the establishment of a well-functioning family unit. Three time frames of assessment Done in the birthing area immediately after birth to determine the need for resuscitation or other interventions Done by the nursery nurse as part of the routine admission procedure. estimate gestational age and evaluate the newborn's adaptation to extrauterine life Done before discharge behavioral assessment and a complete physical examination to detect any emerging or potential problems.
