Q

What are we worried about with a post tree baby?

A

> 42wks we are worried about placonium (first poop)

- it can get into amniotic fluid and then get into their lungs

Q

What is a live born infant?

A

When an infant is born and shows any sign of life such as a beating heat, breath, pulsating umbilical cord and or movement of voluntary muscles
-cord and placenta may or may not be attached

23
Q

Why do we want the cord to be attached to the baby for another 10-15 mins?

A

Want the cord attached until it stopps pulsing (10-15mins) before cutting. Babies that do this are better in the first 3month-1yr of life

24
Q

What do infant morbidity and mortality tell us about a population?

A

These tell us the most about the health of a population. More med care and access to nutrition a population has the fewer cases of infant mortality will be seen
-reflects health and sea of a population

25
Q

What are the statistics on the risk factors for infant mortality?

A

SES of popularion
Low birth weight
-<10% of all births but 2/3 of all info deaths
Preterm infants

26
Q

What is the best defence against infant mortality?

A

7 12 to 10 pounds

3500-4500g

27
Q

What is a zygote?

A

Is created whens per cell fertilizes and egg cell at conception
-Zygote quickly divides into many cells, becomes an embryo and implants itself in the uterine wall where it develops into a fetus

28
Q

What are the 3 layers of the embryo?

A

Ectoderm
Mesoderm
Endoderm

29
Q

What does the ectoderm layer turn into?

A

Epidermis and nerve tissue

30
Q

What does the mesoderm turn into?

A

Everything else thats not eco or endoderm

31
Q

What does the endoderm turn into?

A

GI, excretory and respiratory system lining

32
Q

When does mom start noticing baby movement?

A

15-17 wks

-also depends on if placenta is posterior or anterior

33
Q

What is a critical period?

A

Finite periods during development in which critical events may occur that will have irreversible effects on later developmental stages
-cells grow in number and size

34
Q

What happens if you are malnurished during critical times?

A

Its not possible to revers direction and correct errors in growth or development that occurred during a previous critical period
-consequences last a lifetime

35
Q

What is the difference between hyperplasia and hypertrophy?

A

Hyperplasia: cell number

Hypertrophy: cell size

36
Q

What are the 2 hypothesis for disease risk later in life?

A

H1: Adverse influences at critical times set stage for chronic disease in adulthood

H2: Environmental exposures in utero in the first few years of life may:

  • alter DNA
  • Alter gene functions without altering DNA
  • may affect more than 1 generation
37
Q

Why do we look at birthweight?

A
  • indicator of infant health
  • Strong predictor of subsequent development of infant
  • high birthweight=decreased risk (but not too high)
38
Q

How is baby birth weight influenced by mom?

A

Wt prior to conception

Wt gain during pregnancy

  • total
  • wt gain pattern

Nutrition before pregnancy

39
Q

What is SGA?

A

Small for gestational age

  • <10%
  • Small for the length of time they’ve been growing inside mom
40
Q

what is pSGA?

A

Baby is proportionately small for gestational age. Everything on their body is smaller than what we would normally see. -Tend to stay small throughout life

41
Q

Why would a baby be SGA?

A

Long term inadequate nutrition
Inadequate nutrition intake/maternal weight gain in pregnancy
-Pre-pregnancy weight
Chronic exposure to alcohol

42
Q

How do you fix a baby that is SGA?

A

Catchup growth needed in weight and length

  • Cant have catchup growth to be too fast so they don’t get overwhelmed
  • can increase their risk for obesity and DM2 later

Breastfeeding supports catchup

43
Q

What happens if you have inadequate nutrition in 3rd T?

A

Tend to have academic/intellectual consequences and at increased risk for HD, HT, and DM2 later

44
Q

What is LGA?

A

Large for gestational age

->90th%

45
Q

How does a baby become LGA?

A

Pre pregnancy obesity
Poorly controlled DM
Excessive weight gain during pregnancy

46
Q

What are the consequences of LGA?

A

Increased risk of post party complications
C section
Shoulder dystocia
Post partum Hemmorrhage

47
Q

What is the thrifty phenotype?

A

when mom doesn’t get enough nutritnets, baby learns to deal with what its given. When you overwhelme the baby after bron to try and raise weight, it just acucmulates in the system

48
Q

What physiological changes do we se in mom during pregnancy in the first few weeks of conception?

A
  1. Blood plasma volume increases
  2. Body readjusts body equilibrium and health in certain areas
  3. GI changes
  4. Uterus size
  5. Placenta
  6. Breast size
  7. Increase to circulatory and respiratory systems
  8. Kidneys change
  9. Immune function
  10. Basal metabolism
49
Q

Why does blood plasma volume increase?

A

Provide fetus with adequate nutrient energy and O2

-amount increased can also correlated to baby size

50
Q

What new equilibriums does the body need to establish Lish?

A 
Fluid levels 
-2/3 intracellular 1/3 extracellular
Hemodilution
-lower amount of Fe, folate and BVits for arount of fluid in body
Blood lipids
Glucose metabolism
51
Q

Why does the GI change?

A

Increase nutrient absorption of select nutrients
Increase utilization of nutrients
Relax GI muscle tone

52
Q

What is relaxin?

A

Hormone Relaxin released to allow a lining in the uterus to expand
-See increased reflux here cause of relaxin, and the muscles in the GI can become lazy and lead to constipation. -There is also a lot more pressure in the area which leads to more extreme reflux and constipation the further along in pregnancy you go

53
Q

What is the maternal anabolic phase?

A

0-20 weeks

  • increasing and building stores to give to fetus
  • 10% of fetal growth and weight gain
54
Q

What is the maternal catabolic phase?

A

20+wks

  • increased capacity to deliver energy and nutrient stores
  • 90% of fetal growth and weight gain
55
Q

What are some the changes what occur int he kidneys?

A

Increase GFR =increase thirst
Increase in conservation
Increase nutrient spillage

56
Q

What is high ligament pain?

A

being stretch for the uterus to grow and pelvic area to be ready (towards end of 2nd T and into 3rdT
• Pain after pregnancy in this area beasue the uterus has to shrink back down
