1
Q

1) 1st yr of life
2) by age 3
3) by age 6
A
1) 50%
2) 75%
3) 90%
2
Q
how much does ur brain weigh at…
1) birth
2) by 1st bday
3) by 5-6 yrs of age
A
1) 12%
2) doubles
3) triples
3
Q
how does the pediatric CNS and nerve fibres look
- discuss reflexes, the BBB, and myelination
A
- CNS immature
- nerve fibres poorly developed
- numerous reflexes present initially
- BBB not mature until 2 yrs, so increased risk for meningitis
- myelination over 1st yr of life
4
Q
what are fontanelles and sutures
A
- sutures are separations between bones of skull that have not yet joined
- fontanelles are formed at the intersection of these sutures
allow pass thru birth canal, which cause the brain to grow and expand
5
Q
what are fontanelles covered by
A
tough membranous tissue that protects the brain
6
Q
when does the posterior fontanelle close by
A
2-3 months
7
Q
when are the anterior fontanelle and sutures palpable up till
A
18 months of age
8
Q
what is included in a complete neuro assessment
A
- PEERLA
○ Pupils equal and reactive to light- Newborn Reflexes (When they are present, when they should disappear, etc.)
- Coordination
- Can they follow commands
- Can they move all their limbs
- Hypertonicity - what diagnosis can cause this: NAS (neonatal abstinence syndrome)
- Hypotonicity - what diagnosis can cause this: Ehlers Danlos syndrome, down syndrome
- Ask about seizures
- Palpate the Fontenelle
- Bulging Fontenelle: increased intracranial pressure or fluid overload
- Sunken Fontenelle: dehydration
- Ask pt how old they are, pets, grade are you, who’s here with you?
- Is the behaviour or development appropriate for their age?
- Having no interest in anything -> NOT GOOD
- Correcting their age -> for preemies they should meet their milestones normally at 2 yrs otherwise a bad sign
- Intercranial pressure signs: swelling of their fontanelle, crying
- Cardiac babies don’t have a strong cry
- High pitched cry: sign of increased intracranial pressure or NAS
- Pain: good strong cry
- Neuro Vitals: PERLA, Glasgow coma scale, pupils, and motor strength
Strength of suck
9
Q
what is the #1 code in peds
A
respiratory arrest
10
Q
when does a pediatric resp tract constantly grow/change until
A
12 yrs
11
Q
what are 5 upper airway differences in peds
A
- neck is shorter, resulting in airway structures closer together
- trachea is shorter and narrower, creating risk for obstruction
- newborns are obligatory nose breathers - will not automatically open mouth if nose is obstructed therefore nasal patency is critical
- larynx and glottis high in neck therefore increases risk of aspiration
- tongue is large relative to small nasal and oral airway passages
*nose breathers so keep nasal patency open
12
Q
what are 6 lower airway differences in pediatrics
A
- at birth the lung tissue contains only 25 million alveoli, which are not fully developed
- # of alveoli increases to 300 mil by age 8
- smaller alveoli predispose infants to alveolar collapse
- less lung volume
- children up to age 6 are primarily dependent on their diaphragm to breathe
- CO2 is not effectively expired when child is distressed, making child susceptible to metabolic acidosis
13
Q
why is airway resistance greater in children
A
- greater in children than in adults - children airway is narrower than adults
- in infants, airway resistance is about 15x that of an adult
- w edema and swelling the airway is further narrowed
- airway resistance = harder to breathe = increased WOB
September spike in asthma exacerbation
14
Q
what is included in a complete respiratory assessment
A
- Work of breath
- If u see ribs they have intercostal indrawing or retraction
- Auscultating the lungs: crackles, wheezes, stridor (tracheal swell in croup)
- Oxygen Delivery
- Airway obstruction
- Newborns are periodic breathers
- Air passing through nasal congestion
- Decreased air entry - what intervention: reposition
- Mucus
- Notice any cough
Apnea classification: 20 seconds
15
Q
describe wheezing
A
- musical high pitched squeaking sounds often heard mid to late expiration
- air is squeezed or compress through passageways narrowed almost to closure through collapsing airways, swelling, secretions
- may be high or low pitched
16
Q
describe crackles
A
fine - high pitched crackling or popping sound heard on inspiration not cleared by coughing
- inhaled air collides w previously deflated airways which will pop open
course - low pitched bubbling and gurgling sounds that start in early inspiration and may be present in expiration
- inhaled air collides with secretions in trachea or large bronchi
- sounds like velcro
pneumonia, broncholotis, mucous
17
Q
stridor
A
- high pitched crowing sound
- originated in larynx or trachea
- obstruction from swollen inflamed tissues or lodged foreign body
obstruction, pertussis
18
Q
transmitted sounds heard on auscultation
A
- may seem to originate in the lungs but is referred from the upper airway i.e. mucous in the throat or nose
common in newborns
19
Q
what to look for when doing an assessment for work of breathing
A
- retractions/in drawing
- accessory muscle use
- grunting
- head bobbing
- nasal flaring
- tracheal tug
20
Q
what do kids usually have tachypnea more than adults
A
Kids hearts beat fast, because they cannot beat harder so tachycardia is very common
21
Q
what are CVS pediatric differences
A
- cardiac output is rate dependent not stroke volume dependent
- HR is labile
- during stress, exercise, fever, or respiratory distress, infants and children become tachycardic, which increases their cardiac output
- lower BP: thought to be related to underdeveloped left ventricle
- lower absolute blood volume: vulnerable to fluid and electrolyte imbalances
22
Q
what are potential causes of tachycardia
A
Infection, stress, trouble breathing/respiratory distress, dehydration
23
Q
what is low bp a late sign in children for…
A
dehydration, otherwise their bp doesn’t change much
Children - dehydration is a priority they cannot handle it like adults can
24
Q
what is included in a complete CVS assessment
A
- Murmur - abnormal blood flow
- Capillary refill, less than 3 secs
- Colour of skin: not cyanotic, not pale, not jaundice
- Heart rate for a whole minute
- Cant feel radial until about 4-6 years of age, so feel apically
- Best time to do infant bp is when they r sleeping
- Where are you going to see edema in children: their face and their eyes (periorbital edema), genitals
- Hydration status via skin turgor, weight, mucus membranes
- When dehydrated they won’t have tears or sweat when they are dehydrated

30
why might an infant be cyanotic
- an infant may be cyanotic bc of cardiac or pulmonary disorder
31
cyanosis that worsens with crying is likely due to...
a CVS issue
32
what does crying due to the CVS
increases the pulmonary resistance to blood flow, resulting in increased right to left shunt
33
cyanosis that improves w crying is most likely due too...
pulmonary - deep breathing improves tidal volume
34
acrocyanosis
cyanosis of extremities - normal in newborn
35
peripheral cyanosis
