2 Objective 1Discuss pathophysiology and nursing process for high risk newborn
3 Identification of At-risk Newborn Low socioeconomic level of the motherLimited or no prenatal careExposure to environmental dangersPreexisting maternal conditionsMaternal factors such as age or parityMedical conditions related to pregnancyPregnancy complications
4 Feeding GuidelinesTable 32–1 Suggested feeding guidelines for the preterm infant.
5 Early Feeding Skills (EFS) Table 32–2 Examples of efs items within each section.
6 Preterm Infant: Respiratory Alterations Inadequate surfactant productionMuscular coat of pulmonary blood vessels is not completely developedGreater risk for the ductus arteriosis to remain open
7 Fetal/Neonatal Risk Factors for Resuscitation Nonreassuring fetal heart rate patternDifficult birthFetal scalp/capillary blood sample-acidosis pH<7.20Meconium in amniotic fluidPrematurityMacrosomia or SGA
11 Fetal/Neonatal Risk Factors for Resuscitation (continued) Male infantSignificant intrapartum bleedingStructural lung abnormality or oligohydramniosCongenital heart diseaseMaternal infectionNarcotic use in labor
12 Fetal/Neonatal Risk Factors for Resuscitation (continued) An infant of a diabetic motherArrhythmiasCardiomyopathyFetal anemia
13 Respiratory Distress Syndrome (RDS) Deficiency or absence of surfactantAtelectasisHypoxemia, hypercarbia, academiaMay be due to prematurity or surfactant deficiency

19 Meconium Aspiration Syndrome (MAS) Mechanical obstruction of the airwaysChemical pneumonitisVasoconstriction of the pulmonary vesselsInactivation of natural surfactant
20 MAS: Nursing Care Assess for complications related to MAS Maintain adequate respiratory statusMaintain adequate nutritional statusMaintain adequate hydration
21 Persistent Pulmonary Hypertension (PPHN) Blood shunted away from lungsIncreased pulmonary vascular resistance (PVR)PrimaryPulmonary vascular changes before birth resulting in PVRSecondaryPulmonary vascular changes after birth resulting in PVR
22 PPHN: Nursing Care Minimize stimulation Maintain adequate respiratory statusObserve for signs of pneumothoraxMaintain adequate nutritional statusMaintain adequate hydration statusSupport and educate family
23 Figure 33–10 Chest x-ray of a left-sided pneumothorax Figure 33–10 Chest x-ray of a left-sided pneumothorax. A rupture of the alveoli sacs allows air to leak through the pleura, forming collections of air outside the lung (air shows on x-ray as dark area over lung).

57 Newborn WithdrawalTable 32–4 Clinical manifestations of newborn withdrawal.

69 Preterm Infant: GI Alterations Poorly developed gag reflexIncompetent esophageal cardiac sphincterPoor sucking and swallowing reflexesDifficulty meeting caloric needs for growthInability to handle the increased osmolarity of formula proteinDifficulty with absorbing saturated fats
70 Preterm Infant: GI Alterations (continued) Difficulty with lactose digestionDeficiency of calcium and phosphorousIncreased basal metabolic rate and increased oxygen requirementsFeeding intolerancePotential for the development of necrotizing enterocolitis (NEC)
71 Preterm Infant: Alterations in Thermogenesis Unavailability of glycogen and brown fatInability to increase oxygen consumptionHigh ratio of body surface area to body weightExtended position increases body surface areaDecreased ability to vasoconstrict superficial blood vessels
72 Preterm Infant: Kidney Alterations Lower glomerular filtration rate (GFR)Limited ability to concentrate urine or excrete large amounts of fluidExcrete glucose at a lower serum glucose levelBuffering capacity is reducedExcretion time of drugs is longer
73 Preterm Infants: Liver Alterations Glycogen stores are used rapidlyGlycogen stores are affected by asphyxia and cold stressLow iron storesConjugation is impaired
74 Preterm Infants: Other Alterations ImmunologicLack of passive IgG antibodiesSkin is easily excoriatedNeurologicIncreased risk for IVH & ICHDelayed or absent reactivity

77 Intrauterine growth restriction Small for gestational ageLarge for gestational agePost term infant
78 Intrauterine Growth Restriction Infants <10th percentile for weight at birthMay be symmetric or asymmetricFactors may be fetal, maternal, or placentalComplicationsHypoxia, hypothermia, hypoglycemia, polycythemia, hyperbilirubinemia, meconium aspiration
79 Intrauterine Growth Restriction (continued) Nursing implicationsPrevent heat lossMonitor blood glucose, feed earlyMonitor for respiratory complicationsManagement of hyperbilirubinemia

83 Impact of Maternal Diabetes Mellitus (DM) on the Newborn LGASGAHypoglycemiaHypocalcemiaHyperbilirubinemia
84 Impact of Maternal Diabetes Mellitus (DM) on the Newborn Birth traumaPolycythemiaRDSCongenital malformations
94 Management of Hyperbilirubinemia Encourage frequent feedingsExposure to sunlightPhototherapyShield infant’s eyesMonitor body temperatureMonitor weightMonitor fluid intakeWeigh diapersNote frequency of stools
95 Physiologic Hyperbilirubinemia Appears after first 24 hours of lifeDisappears within 14 daysDue to an increase in red cell mass
96 Pathologic Hyperbilirubinemia Appears within first 24 hours of lifeSerum bilirubin concentration rises by more than 0.2 mg/dL per hourBilirubin concentrations exceed the 95th percentileConjugated bilirubin concentrations are greater than 2 mg/dLClinical jaundice persists for more than 2 weeks in a term newborn
97 Causes of Pathologic Hyperbilirubinemia Hemolytic disease of the newbornErythroblastosis fetalisHydrops fetalisABO incompatibility
98 Treatment of Pathologic Hyperbilirubinemia Resolving anemiaRemoving maternal antibodies and sensitized erythrocytesIncreasing serum albumin levelsReducing serum bilirubin levelsMinimizing the consequences of hyperbilirubinemia
99 Phototherapy: Nursing Care Maximize exposure of the skin surface to the lightPeriodic assessment of serum bilirubin levelsProtect the newborn’s eyes with patchesMeasure irradiance levels with a photometerGood skin care and reposition infant at least every 2 hoursMaintain an NTE and adequate hydration and nutrition

101 Nutrition and Fluid Management FluidsStrict I&O, weigh diapersElectrolyte managementManagement of sodium and potassium levelsGlucose homeostasisFeedingGavage or nipple methodTypes: formula or breast milkGavage feeding tube
102 Developmental Care of the Preterm Infant LightSoundTemperaturePositioning and containment strategiesHandling and touchingNonnutritive sucking
103 Cold Stress Increase in oxygen requirements Increase in utilization of glucoseAcids are released in the bloodstreamSurfactant production decreases
104 Figure 33–13 Cold stress chain of events Figure 33–13 Cold stress chain of events. The hypothermic, or cold-stressed, newborn attempts to compensate by conserving heat and increasing heat production. These physiologic compensatory mechanisms initiate a series of metabolic events that result in hypoxemia and altered surfactant production, metabolic acidosis, hypoglycemia, and hyperbilirubinemia.
105 Cold Stress: Nursing Care Observe for signs of cold stressMaintain NTEWarm baby slowlyFrequent monitoring of skin temperatureWarming IV fluidsTreat accompanying hypoglycemia
106 Objective 2Explain the assessment and nursing interventions associated with birth injuries
107 Trauma and Birth Injuries FracturesClavicle, long bones, skull most commonRisksLarge infant, breech, difficult laborAssessmentImpaired mobilityManagementImmobilization, traction, casting
108 Trauma and Birth Injuries (continued) Facial PalsyUsually related to use of forcepsBrachial PalsyUsually related to difficult delivery such as shoulder dystociaAssessmentImpaired mobility of armParalysis may be temporary or permanent
109 Needs of Parents of At-risk Infants Realistically perceiving the infant’s medical condition and needsAdapting to the infant’s hospital environmentAssuming primary caretaking roleAssuming total responsibility for the infant upon dischargePossibly coping with the death of the infant if it occurs
110 Facilitating Parental Attachment Facilitating family visitsAllowing the family to hold and touch the babyGiving the family a picture of the babyLiberal visiting hoursEncouraging the family to get involved in the care
