    NURSING MANAGEMENT OF THENEWBORN AT RISK:Utilizing the Nursing Process andCritical Thinking

    Lecture Objectives:

    1. Describe risk factors associated with thebirth and transition of an infant of adiabetic mother.

    2. Discuss maternal substance abuse andthe newborn.

    4. Discuss gestational problems in theneonate.

    5. Discuss infection and the newborn.

    Lecture Objectives: (cont.)Discuss hemolytic disorder in the newborn.Develop a plan of care to meet the needs ofparents of high risk infants.Discuss the treatment and complications ofrespiratory distress syndrome.Describe nursing interventions for nutritionalcare of the preterm infant.Discuss thermoregulation and its role in thecare of the preterm infant.

    Infants with GestationalAgeRelated Problems

    High Risk NewbornInfants who are born considerably beforeterm and survive are particularly susceptibleto development of sequelae related topreterm birth

    High Risk NewbornHigh risk infant classification

    Birth weightGestational agePredominant pathophysiologic problems

    Preterm Infants

    Organ systems are immature and lackadequate physiologic reserves to functionin extrauterine environmentPotential problems and needs of preterminfant weighing 2000 g differ from those ofterm, postterm, or postmature infant ofequal weightPhysiologic disorders and anomaliesaffect infants response to treatment

    Preterm Infants

    Closer infants are to term, the easier theiradjustment to external environmentVarying opinions exist about practical andethical dimensions of resuscitation ofextremely low-birth-weight infants

    Birth weight is 1000 g or less

    Key PointsPreterm infants at risk for problemsrelated to the immaturity of their organsystemsRespiratory distress syndrome,retinopathy of prematurity, andchronic lung disease(bronchopulmonary dysplasia) areassociated with prematurityHigh risk infants must be observed forrespiratory distress and other earlysigns of physiologic distress

    Key PointsMetabolic abnormalities of diabetesmellitus adversely affect embryonicand fetal developmentAdaptation of parents to preterm orhigh risk infants differs from that ofparents of full-term infantsParents need special instruction (e.g.,CPR, oxygen therapy, suctioning,developmental care) before they takea high risk infant home

    Key Points

    Infants born to diabetic mothers are atrisk for hypoglycemia and RDSSGA infants are considered to be at riskbecause of fetal growth restrictionNonreassuring fetal status amongpostmature infants is related toprogressive placental insufficiency thatcan occur in postterm pregnancy

    The Newborn at Risk:Acquired and Congenital

    Problems

    Acquired and CongenitalProblems

    Conditions or circumstancessuperimposed on normal course ofevents associated with birth andadjustment to extrauterine existenceBirth trauma includes physical injuriessustained during labor and birthCongenital anomalies: gastrointestinal(GI) malformations, neural tubedefects, abdominal wall defects, andcardiac defects

  • 11

    Birth Trauma

    Injury sustained during labor and birthBirth injuries may be avoidable

    Careful assessment of risk factors andappropriate planning of birth

    Ultrasonography allows antepartum diagnosis ofmacrosomia, hydrocephalus, and unusualpresentationsElective cesarean birth chosen for somepregnancies to prevent significant birth injury

    Birth Trauma

    Small percentage of significant birthinjuries are unavoidable despite skilledand competent obstetric care

    Especially with difficult or prolonged laborWhen the infant is in an abnormalpresentation

    Some injuries cannot be anticipated untilthe circumstances are encounteredduring childbirth

    Hemolytic DisordersHemolytic disease occurs when bloodgroups of mother and newborn aredifferent

    Most commonRh incompatibilityABO incompatibility

    Occur when maternal antibodies arepresent naturally, or form in response toantigen from fetal blood crossing placentaand entering maternal circulation

    Hemolytic Disorders

    Maternal antibodies of IgG class crossplacenta, causing hemolysis of fetalRBCs

    Fetal anemiaNeonatal jaundiceHyperbilirubinemia

    Hemolytic Disorders

    Rh incompatibility (isoimmunization)Only Rh-positive offspring of Rh-negative mother is at riskIf fetus is Rh positive and mother Rhnegative, mother forms antibodiesagainst fetal blood cells

  • 16

    Hemolytic Disorders

    ABO incompatibilityOccurs if fetal blood type is A, B, orAB, and maternal type is OIncompatibility arises becausenaturally occurring anti-A and anti-Bantibodies are transferred acrossplacenta to fetusExchange transfusions requiredoccasionally
