Newborn Complications Flashcards
Describe newborn complications in term infants.
When do they occur? What are some common complications?
- Complications can still occur in term infants:
- If optimal transition does not occur
- Affected by maternal disease or IUGR (hypoglycemia, hypothermia, respiratory, hyperbilirubinemia etc.)
- Affected by maternal infection
- Traumatic birth
- More often seen in LGA, SGA or IUGR infants
- Common term complications:
- Transient tachypnea of the newborn
- Hyperbilirubinemia
LGA - large for gestational age
SGA - small for gestational age
AGA - appropriate for gestational age
IUGR - Intrauterine Growth Restriction (small, but still fetus)
What are causes of preterm complications?
(contributing factors)
- Assistive reproduction
- Genetics
- Maternal disease processes
- OB history
- Placental insufficiency
- Socioeconomics
What is Transient Tachypnea of the Newborn (TTN)?
- Delayed clearance of fetal lung fluid from lungs
- More likely to occur in babies delivered via c/s,
esp. if labor did not occur before birth
- More likely to occur in babies delivered via c/s,
What are signs and symptoms of TTN?
- Respiratory rate > 60 breaths/min.
- Cyanosis
- Grunting
- Nasal flaring
- Retracting
What are Nursing Care & Priorities for TTN?
- Monitor respiratory rate
- Minimal exertion
- No oral feeding (or very limited)
- Supplemental oxygen
What can contribute to TTN?
- Cesarean delivery without labor
- <39 weeks
- Maternal diabetes
- SGA/LGA
- Traumatic delivery
Why do premature infants have respiratory problems?
- Bones of thorax not calcified
- Decreased number of functional alveoli
- Deficient surfactant levels
- Greater collapsibility or obstruction of respiratory passages
- Greater distance between functional alveoli and the capillary bed
- Immature and friable capillaries in the lungs
- Small airways
- Weak or absent gag reflex
What is Respiratory Distress Syndrome (RDS)?
- Breathing disorder caused by immature (premature) lungs
- Lack of surfactant
- The more premature (earlier the gestation) the higher the chance of RDS
What are signs and symptoms of RDS?
- Decreased breath sounds
- Fine rales
- Generalized cyanosis
- Grunting
- Nasal flaring
- Retractions
- Rapid shallow breathing
- Shortness of breath
- Tachypnea then apnea
S&S generally present 4-24 hours of life
Who does RDS affect?
- Most common in premature infants born <34 weeks
- Infants of diabetic mothers
- Problems that reduce blood flow to infant
- Rapid labor, multiple pregnancy, asphyxiated infants
How do you decrease severity of RDS?
Prenatal corticosteroids (betamethasone, 2 doses given 24 hours apart)
How is RDS treated?
- Exogenous surfactant
- Mechanical support prn (CPAP, ventilator)
- Warm moist oxygen
Describe Surfactant.
- Fetus begins producing between 24-28 weeks
- Administered through the endotracheal (ET) tube
- Composed of lipids and proteins
- Equalizes pressure between large and small spaces
- Prevents alveoli from collapsing
- Reduces surface tension
Compare TTN and RDS.
Who does it effect and how should support be given?
TTN
- Unique to the term infant
- Generally time-limited with little respiratory support needed
RDS
- Affects preterm infants
- Requires aggressive support
- Can lead to complications such as BPD
Which infants are at risk for Hypothermia?
and why?
Infants at risk:
- Low birth weight infants
- Preterm Infants
- Birth asphyxia/trauma
- Due to limited ability to increase metabolic rate
- Immaturity of skin → Increased transepidermal water loss
What are the signs and symptoms of hypothermia?
- Acrocyanosis
- Hypoglycemia
- Mottled
- Pale
- Skin is cool to touch
- Respiratory distress
What can hypothermia lead to?
- apnea/respiratory distress
- bradycardia
- central cyanosis
- hypoglycemia
- acidosis
What is nursing care for hypothermia?
- Maintain a neutral thermal environment
- Pre-warmed isolette or radiant warmer
- Plastic bag for very low birth weight infants (VLBW)
- Skin to skin
- Warm infusions
- Monitor temperature, blood sugars
What is Hypoglycemia?
- Abnormally low blood sugar levels (lower than 40 in the first 72 hours)
- Glucose levels stabilize by 2-3 days of life
Which infants are at risk for Hypoglycemia?
- SGA (Small for Gestational Age)
- LGA (Large for Gestational Age)
- preterm
- low birth weight
- Infant of Diabetic Mothers (IDM)
- Infants who experience perinatal stress
- asphyxia, cold stress or respiratory distress
- those with active infection
What are the signs and symptoms of hypoglycemia?
- Abnormal cry
- Apnea
- Hypotonia
- Jitteriness
- Lethargy
- Poor feeding
- Respiratory distress
- Seizures
- Temperature instability
How to manage hypoglycemia?
- Early and frequent feeds
- Monitor blood sugar levels in at risk infants
Describe Necrotizing Enterocolitis (NEC)?
- Acute inflammatory disease of the GI mucosa, commonly complicated by bowel necrosis and perforation
- Most of the time, this is a pre-term baby issue
- Breastmilk is gold standard for protection against NEC
What can cause NEC?
- Intestinal ischemia occurs as a result of asphyxia/hypoxia or redistribution of blood flow away from GI tract
(hypotension, hypovolemia, stress etc.) - Bacterial colonization of the GI tract with harmful organisms
- Enteral feeds
