Assessment tools
Nursing Interventions
Swaddling
Comfort measures
Pharmacologic measures    *
* Inadequate nutrient stores and digestive capacity
* Require approximately 105-130kcal/kg/day
* Require more protein, iron, calcium, and phosphorous
* Inadequate absorption of nutrients in gastrointestinal tract
* Smaller stomach capacity


                                       *
* Respiratory Distress Syndrome (RDS)

* Bronchopulmonary Dysplasia (BPD)

                                        *
* Necrotizing Enterocolitis (NEC)

* Post-term Infants

* Small for Gestational Age (SGA)

* Large for Gestational Age (LGA)

              *
* Cleft lip and palate
* Esophageal
 atresia/tracheoesophageal
 fistula
* Omphalocele/gastroschisis
* Diaphragmatic hernia
* Neural tube defects
* Congenital hydrocephalus

        *
* Ventricular septal defect(VSD)
* Patent ductus arteriosus(PDA)
* Coarctation of the aorta
* Tetralogy of Fallot
* Transposition of the great arteries

            *
* Cyanosis  with crying   * Tachypnea
* Pallor                   * Dyspnea
* Murmurs                  * Choking spells
* tachycardia              * Poor intake
                           * diaphoresis

              *
*Asphyxia: lack of O2 and increase of CO2 in the
 blood.
*Transient tachypnea of the newborn(TTN):
 retained lung fluid
*Meconium aspiration syndrome(MAS): aspiration
 of meconium stained fluid.
*Persistent pulmonary hypertension of the
 newborn(PPHN): the vascular resistance of the
 lungs does not decrease after birth and normal
 changes to neonatal circulation are impaired.




                *
* Infection is a major cause of death during the neonatal
 period
* Vertical transmission; before or during birth
* Horizontal transmission; after birth by contact with
 hospital staff, contaminated equipment, family



                     *
* Sepsis; systemic, bacteria in the bloodstream
* Most common organisms GBS & E.Coli
* Early vs late onset
* CBC with differential, blood cultures & C-reactive
 protein(CRP)
* Broad spectrum antibiotic therapy
                     *
* Temp. instability       * muscle tone
* Tachypnea               * hypoglycemia
* RDS                     * Jitteriness
* Cyanosis/pallor         * Irritability
* oral intake            * Bulging fontanel

                      *
*Appears in the first 24 hours
*Kernicterus: acute bilirubin encephalopathy
*Hemolytic disease caused by RH
 incompatibility, antibodies attach to fetal
 RBC’s and destroy them
*ABO incompatibility
*Prevention of kernicterus
*Phototherapy; bilirubin in the skin absorbs
 light & changes to water-soluble
 photoisomers excreted in urine and bile

        *
*Occurs in 10-15% births; 5% develop MAS
*Occurs most often in post-term infants who
 have AFI and are prone to cord compression
*Occurs in infants who have suffered
 intrauterine asphyxia
*Results in obstruction, pneumonitis,& air
 trapping
*Amnioinfusion, mechanical suction on
 perineum


       *
*Neonatal abstinence syndrome(NAS )
*Prenatal opiate exposure sufficient enough to
 cause withdrawl signs after birth
*Codeine, tranquilizers, & sedatives
*SGA, preterm, RDS, jaundice, SIDS
*Special care to cope with drug withdrawl
*Care focuses on rest, feeding, & parental
 attachment
              *
*Genetic disorder that causes CNS damage
 from toxic levels of the amino acid
 phenylalanine in the blood
*Liver enzyme deficiency preventing normal
 conversion of phenylalanine
*In the USA, all newborns are screened after
 12 hours of age
*Requires special diet throughout life

           *
*Hypospadias/Epis
 padias
*Phimosis
*Ambiguous
 Genitalia
*Exstrophy of the
 Bladder
