BRS1 Flashcards
what are standard growth curves
represent growth for age of 95% of children. can plot weight, height, BMI and head circumfrance
what is FTT
this is abnormal growth. concern when the child’s weight crosses two major percentile isobars
expected weight gain birth - 3 months
30grams/day. regain birth weight by 2 weeks
expected weight gain 3 months- 6 months
20 grams/day
double birth weight by 4-6 months
expected weight gain 6-12 months
10 grams/day
triple birth weight by 12 months
expected weight gain 1-2 yrs
250 grams/month
expected weight gain 2 yrs- adolescence
2.3 kg /year
expected height increase 0-12 months
25 cm/year. birth length should increase by 50% by 12 months
expected height increase 13-24 months
12.5 cm/year
expected height increase 2 yrs to adolescence
6.25 cm/year.
birth length doubles by age 4
birth length triples by age 13 yrs
most common cause of FTT
inorganic- problems with mom and baby bonding, inadequate intake etc.
when does majority of head growth occur
between first 2 years of life
expected head growth 0-2 months
.5 cm/week
expected head growth 2-6 months
.25 cm/week
expected head growth by 12 months
total increase is 12 cm since birth
head circumfrance at birth is ___ % of normal adult head size
25%
head circumfrance at 1 yr is ___ % of normal adult head size
75%
microcephaly definition
head circumfrance is 2-3 standard deviations below mean for age. always associated with a small brain. think cerebral palsy or seizures
craniosyntosis
premature closure of one or more cranial sutures
diseases assocaited with craniosyntosis
Crouzen and Apert syndromes, intrauterine crowding, metabolic abnormalities- hyperthyroidism, hypercalcemia
when is brain growth complete
by age 5. 90% done by age 2
dolichocephaly or scaphocephaly
premature closure of sagittal suture. head is longer and narrower
brachycephaly
premature closure of the coronal suture. optic nerve damage
trigonocephaly
premature closure of metopic suture. angular shaped head.
plagiocephaly
asymmetry of the infant head. not associated with premature suture closure
