When is the neonatal transition period? Ad what are the periods?

-first 8 hours after birth
- first period of reactivity
- sleep period
- second period of reactivity

1

What is the first period of reactivity

First 30 minutes after birth.
Alert and hungry
Heart rate may go upto 180
Should allow this time for breast feeding and bonding

2

Sleep period

Heart rate and motor activity decrease as they sleep

3

Second period of reactivity

4-8 hours post birth
Baby awake and ready to feed
If bottle fed, this is the first feeding
May pass meconium
Active body parts

4

Why is the neonatal period so important

Go from intrauterine cardiopulmonary circulation to doing it themselves

5

What are the different indicators of respiration?

Surfactant
Stimulation
Periodic breathing
Apnea
Respiratory distress

6

What's the most important initial step for a newborn

For the baby to start breathing

7

What is surfactant and what is the ratio?

Have to have stimulation to breath can be from chemical, CO2 increase and thermal stimulation

L:S ratio is 2:1

8

What is periodic breathing?

Irregular respirations
May have pauses upto 20 seconds, no color changes

9

What is apnea?

Pause longer then 20 seconds and requires stimulation
No neurological development

10

What is respiratory distress?

#1 is tacipnea
30-60 respiratory rate
Look for nasal flaring as baby uses accessory muscles

11

What is the cardio pressure before birth? And after birth?

High pulmonary vascular resistance: lungs full of water
Low systemic vascular resistance: little resistance to blood leaving heart
Pressure in heart is right to left

Low pulmonary vascular resistance: full of air so not much resistance
High systemic vascular resistance
Pressure is left to right

12

What is a foremen ovale?

Hole between atria of the heart that closes 1-2 hours post birth
Pressure increases on left side that closes due to pressure change

13

What is the ductus arteriosus?

Connects aorta to pulmonary vein so it goes to across the aorta before in the lungs
Close within 15 hours of birth due to high oxygen levels

14

What is the heart rate in cardiovascular transition

100-160

15

What is the blood pressure in cardiovascular transition

60-80/40-50mm Hg

16

What is a PDA murmer?

Common because it takes time for ductus arteriosus not closed
Happens between S1 and S2

17

What is the neonatal hemoglobin blood value?

80% blood cells carry this
Higher at 14-24 g/dL

18

What is the hematocrit neonatal blood value?

Higher than 44-64%

19

What is the WBC neonatal blood value?

18,000 at birth and 24,000 the next day.
Better indicator is a crp (c-reactive protein)
Don't have good inflammatory response

20

What is neonatal blood value blood group and type

Established 4 months of gestation. Check rH factor.

21

What are the two types of thermogenesis

Non-shivering thermogenesis
Neutral thermal environment

22

What is non-shivering thermogenesis

Do not regulate temperature well
This is why we use radiant Warmers
Increase activity
Brown fat metabolism

23

What is brown fat metabolism

Newborns metabolize it for heat
By shivering up glucose and oxygen
When heat up fat end up with acidosis

24

What it NTE

Neutral thermal environment
T: 97.7 - 99.4 F

25

What is cold stress

Can be fatal
Increased CO2 levels
Hyper bilirubin causes jaundice
Size and amount of adaptor tissue, gestational age and birth weight determine how he thermoregulates

26

What are the four heat loss mechanisms?

Evaporation
Conduction: cold touching warm skin
Convection: air current, maintain nursery temp at 80, keep away from window
Radiation: not in direct contact with

27

What are important milestons in the newborn renal system

First void within 24 hours
Pale urine
Document their first void
Kidney immature so not concentrated well

28

What is suck and swallow

Required for nutrient intake

29

What is the glucose for the GI system

Levels 50-60 and increase 60-70 as baby feeds
Do blood glucose at birth
If <45 have standing order for glucose water
