1

Ages for all pediatric age groups
newborn
infant
toddler
preschooler
school age
adolescent

newborn- 0-1 MOA
infant- 1-12 MOA
toddler-1-3 YOA
preschooler- 4-6 YOA
school age- 6-13 YOA
adolescent- 13-18

2

What facilitates the newborns first breath

Hypoxia
acidosis
sensory stimulation
(cord clamping, pain, touch, noise)

3

Foramen Ovale closes when and r/t what

2-3 months
r/t decreased RAP, Inc SVR thus Inc LAP

4

Ductus Arteriosus closes when (3 stages)

1) 2-3 hours muscles constrict
2) 1-8 days thrombus
3) 1-4 months complete anatomic

5

Ductus Venosus closes when

1-3 hours

6

why are kids hard to mask ventilate

large tongue
Obligate nasal breathers
Narrow nasal airways

7

Why are kids hard to intubate

Kare U shaped epiglottis (stiff)
small submental space
Large tongue
Large occiput
Short neck

8

Why are uncuffed tubes used to intubate peds

to facilitate an increased internal diameter

9

You should hear a leak at what with uncuffed tubes

20-25 cmH20

10

Why do peds chest move less than adults during ventilation

ribs horizontal coming off vertebrae (opposed to the downward displacement of adults)

11

Respiratory physiology of newborns

Increased O2 consumption
Increased Metabolic rate
Increased Alveolar ventilation
Increased Ventilatory rate
Decreased FRC
Increased closing capacity

12

Neonates CO is MOSTLY dependent on what? and why?

HR
b/c they have fixed stroke volume

13

Why can the fetus maintain a lower PaO2

HbF has higher affinity for O2

14

Why is there a physiologic anemia between ages 2-3 months

reduction of the HgF r.t breakdown and metabolism (Hgb life span ends)

15

mylenation is not complete until what age

3 YO

16

the spinal cord ends where in peds

L3

17

GERD is seen in approx what % of all newborns the 1st week of life?

40-50%

18

Why is it difficult for neonates/ newborns to regulate temp

immature ANS
Thin skin
decreased fat
increased BSA to weight ratio

19

how can you est peds weight

(age x 2) +9 = kg in 50th %

20

peds have a higher water concentration 75%. this creates a much larger Vd what does this mean

need more drug for same effect ( meds will diffuse throughout a greater volume and have less effect)

21

Oral route
form
pros
ionization (importance)
metabolism
for what age groups

-ease of use
-liquid
-acid > stomach
Basic >intestines
-1st pass
-toddlers and children

22

Rectal
3 pathways

-Superior
empties into portal system (1st pass)
-Middle/Inferior
empties into systemic circulation

23

IM
2 locations?
why not use dorsal gluteal?
total volume for ages?

- Vastus lateralis (small) Deltoid (older)
-nerve injury or vascular injury
-small Infant- 0.5 ml
Older infant 1 ml
school age 2mL
adolescent 3 ml

24

IV
cons?

difficult to access

25

with induction doses there is a decreae in what 4 things???? but regarless the large Vd requires higher doses

protein binding
increased blood flow to VRG
decreased muscle/fat tiissues
faster redistribution to non VRG

26

Doses compared to adult
Prop and Ketamine

Prop ped 2-3 adult 1.5-2.5
ketamine ped 1-2 adult 1

27

What type of infusions should never be continued into the ICU for sedative purposes

Propofol

28

with NMBD and kids you will give larger doses due to larger Vd but this also means what

longer duration do to immature organs

29

Why not use suxs with kids

more sensitive to adverse effects
(HyperK, dysrhythmias, rhabdo/ masseter spasms/ MH)

30

If a ped has cardiac arrest after induction with suxs how do you treat

as if they became acutely hyperK+
