Newborns who are susceptible to morbidity (illness) or mortality (death) due to: Dysmaturity, Immaturity, Physical disorders, Antepartum conditions, Complications during or after birth
Predictable risk factors
Low socioeconomic level of mother
Limited access to health care
Exposure to environmental issues
Maternal conditions
Health problems
Age
Parity
Pregnancy complications
Gestational age
Preterm: less than 36 weeks & 6 days
Late Preterm: 34-36 weeks & 6 days
Early Term: 37-38 weeks & 6 days
FULL Term: 39-40 weeks & 6 days
Late Term: 41- 41 weeks & 6 days
Post-term: 42 weeks and beyond
Small for gestational age (SGA)
Any infant who is less than the 10th percentile for birth weight
Large for gestational age (LGA)
Any infant who is at or above the 90th percentile for birth weight
Intrauterine growth restriction (IUGR)
Fetus with limited growth potential during pregnancy due to a variety of factors
Infants of diabetic mothers (IDM)
Any infant of a mother with either pre-existing diabetes or gestational diabetes
Maternal Factors leading to SGA or IUGR
Multiples
Smoking
PIH or CHTN
Maternal age < 16 or > 40
Grand multiparity (> 6 pregnancies)
Malnutrition
Heart disease
Substance abuse
Diabetes
Sickle cell
Environmental factors leading to IUGR
Living at High altitude
Exposure to x-rays
Exposure to toxins
Maternal use of medications such as anticonvulsants
Maternal use of drugs such as opioids and many others
Placental factors leading to IUGR
Small placenta
Infarcted areas
Placenta previa or thrombosis
Abnormal cord insertion
Single umbilical artery (rather than the normal pair)
Fetal factors contributing to IUGR
Congenital viral infections such as TORCH infections: Toxoplasmosis, Other, Rubella, Cytomegalovirus, Herpes
Congenital malformations
Metabolic issues
Chromosomal issues
Symmetric IUGR
Caused by long term maternal conditions, chronic growth restriction throughout pregnancy, baby is small all over including organs, length, body weight, head circumference, discovered as early as second trimester (by sono)
Asymmetric IUGR
Caused by acute compromise of uteroplacental blood flow, may not be discovered until third trimester, baby appears disproportionate, head circumference and length may be WNL, abdominal circumference and weight will be decreased
Factors leading to LGA
Genetic predisposition
Large parents often have large babies
Male infants are larger on average than female infants
Multiparity
Much more common after the first pregnancy
Additional Factors leading to LGA
Erythroblastosis fetalis
Beckwith-Weidmann syndrome
Transposition of the great vessels
Maternal diabetes that is poorly controlled during pregnancy*
Macrosomia
May occur in 40-50% of diabetic pregnancies, due to high levels of glucose crossing the placenta which is stored as fat by the growing fetus
Infant with postmaturity syndrome
Those newborns delivered after 42 weeks gestation who have problems associated with an extended pregnancy, the placenta may begin to deteriorate after about 41 weeks, this can lead to poor blood flow, decreased nutrients and decreased oxygen to baby, baby may not tolerate labor well
Characteristics of Post-Mature Newborn
Dry, cracked, peeling skin (parchment like)
Long fingernails/hair
No vernix
No lanugo
Body long, thin, wasting
Head circumference and length typically WNL
Meconium staining
Rh incompatibilities
Rh positive infants of Rh negative mothers at risk for destruction of red blood cells resulting in jaundice and hyperbilirubinemia (or worse)
ABO incompatibilities
Infants with blood Type A, B, or AB whose mother is blood type O are at similar risk
Common Complications of at Risk Newborns
Cold stress
Hypoglycemia
Jaundice
Cold stress
Occurs when newborns lose more heat than their bodies can produce
Hypoglycemia
Low blood sugar
Jaundice
A yellow discoloration of the skin & sclera caused by elevated levels of bilirubin
Signs of cold stress
Increased movements
Increased respirations
Decreased skin temp.
Decreased peripheral perfusion
Hypoglycemia
Metabolic acidosis
Nursing interventions for cold stress
Warm baby slowly, using isolette or radiant warmer
-Necessary if the newborn's blood glucose drops to less than 45-47 mg/dL, or anytime symptoms are present
-early feedings in the first hour of life, recheck after 30 minutes
-may need continuous iv fluids
-feed ever 2-3 hours and check glucose before each feed for 12 hours
-dextrose gel for asymptomatic infants with glucose of 20-40
Hypoglycemia symptoms
Lethargy, sleepiness
Poor feeding/vomiting
Poor sucking/swallowing
Temperature instability
Apnea/dyspnea/cyanosis
Limpness
Tremors/jitteriness
High pitched cry
Exaggerated Moro reflex
Hypoglycemia nursing interventions
Prevention is best, so promote early and regular feedings
Perform heel stick to obtain blood sample for blood glucose testing
IV infusion of dextrose solution may be necessary
Physiologic jaundice
Appears after the first 24 hours of life and typically resolves within 1 week
Breastfeeding jaundice
Can occur in the first few days of life and is related to inadequate fluid intake
Hyperbilirubinemia
A more serious condition which also causes jaundice, and requires intervention. Sometimes caused by ABO or Rh incompatibility. Intervention is necessary if bilirubin exceeds 13-15 mg/dL.
Jaundice symptoms
Bilirubin level > 4-6 mg/dL
Yellow tint to skin when blanched at forehead or sternum
Jaundice interventions
Prevention is best with early and frequent feedings to keep baby hydrated and help eliminate bilirubin via urine and stool
Phototherapy (protect baby's eyes)
Exchange transfusion
Newborn Growth Chart Activity
1. Chart the growth of a specific newborn based on information provided
2. Decide if newborn is SGA, AGA, LGA
3. Based on risk factors decide what additional problem(s) this infant may have
4. Identify complications to look for
5. Identify priority nursing interventions for this baby
6. Discuss measures that could prevent or reduce risk factors
Ways to prevent cold stress after exam
Reswaddle
baby hat
educate parents
Two types of jaundice
physiological or newborn
after24 hours of life
usually due to increase in redcellmass and shortRBClifespan,sloweruptake of bilirubin lack of intestinalbacteria, poor hydration
Peaks at at 3-5 days
pathological jaundice
before24 hours of life
cause is usually hemolyticdiseases
peak is variable
LGA
large for gestational age
Risk factors - diabetics, multipare, males, erythroblastosis fetalis, beckwith-weidman syndrome, transportation of great vessels
