Pre,Peri and Post Natal Issues, and Prematurity - Test 1 Flashcards
Define preterm.
infant born before 38 weeks of gestation or less
9.8% of births - preterm
Low birthweight =
very low birthweight =
2500 grams
1500 grams
define :
natal
pre-natal
birth
before birth
autosomal dominant
abnormal gene passed on from one of the non-sex chromosomes. (NEUROFIBROMITOSIS)
autosomal recessive
gene must be carried from both parents (1/4 chance of getting disease)
sex-linked
Sex linked abnormal gene is passed on sex-linked chromosome by the mother
polygenic or multifactorial
Many genes passed from both parents
Syphilis
Caused by hepatitus, can lead to death, feeding problems, and neurological deficits
Toxoplasmosi
Can get it from changing cat litter and sand boxes or eating raw meat- fecal matter from cats can cause death, hydrocephaly, liver damage, and chorioretinits (blindness)
rubella (measles)
used to be more common prior to vaccination, although may become more of an issue because parents aren’t vaccinating their children due to the autism scare. Can cause deaf/blindness, MR, heart defects
cytomegalovirus
type of herpes spread through the body fluids, multiple system involvement passed onto baby- Can cause multiple neurological conditions and deafness, very severe for: organ transplants, AIDs patients, and developing fetuses
BRONCHOPULMONARY DZ (BPD)
acute respiratory problem that requires prolonged use of ventilator.
Extracorporeal Membrane Oxygenation (ECMO
life support using a cardiopulmonary bypass.
MECONIUM ASPIRATION SYNDROME (MAS
aspiration of meconium into trachea and bronchi.
APNEA
prolonged pause in respiration, accompanied by slowing of heart rate.
RESPIRATORY DISTRESS SYNDROME (RDS)
air sacs of term babies kept open by a chemical coating called surfactant for gas exchange to occur. In premature infant doesn’t produce surfactant the lungs will collapse.
PATENT DUCTUS ARTERIOSIS
blood backing into lungs
Hypoxic-ischemic encephalopathy:
lack of oxygen due to many factors (perinatal), seizures are associated.
Intraventricular or intracranial hemorrhage (IVH):
bleeding into cerebral ventricles and surrounding brain tissue.
GRADE 1 & 2 BRAIN BLEEDS - can be reversible
GRADE 3- Can cause motor problems, can cause cerebral palsy. If half the tracts are affected it can cause spastic diplegia.
GRADE 4- Most severe, involves bleeding into ventricles, can cause more severe cerebral palsy
PERIVENTRICULAR LEUKOMALACIA (PVL):
necrosis of white matter below the cortex around the ventricles.
HYDROCEPHALUS
inflammation from blood in ventricles impedes circulation and re-absorption of CSF. Build-up of CSF in the ventricles of the brain.
DELAYED MOTOR SKILLS
HYPERBILLIRUBEMIA
excess of bilirubin, referred to as jaundice
NECROTIZING ENTERCOLITIS (NEC)
necrosis of the mucosa of the small intestine and colon
MALNUTRITION
referred to as failure to thrive if not maintaining adequate calories or inadequate absorption of nutrients
