Q

Suctioning used to clear the mouth and nose after birth?

What else does this do?

Q

First period of reactivity newborn behavior

A

Awake, active, and hungry using the suck reflex. Will try to start breastfeeding due to Oxytocin - which is helped bu skin to skin that happens here too.

Q

What are some thermal changes that occur?

What if they get too cool or hypothermic?

A

The baby in utero is warm but outside it is cold. This change stimulates nerves to drive breathing

If hypothermic, causes respiratory depression. We will get them under a warmer to avoid this.

Q

How can delayed cord clamping affect the baby?

Treatment?

A

Increased jaundice bc the cord is their line to rbc

Treatment is phototherapy btw

59
Q

Core temp?

What should we do to keep newborn warm?

What can they wear?

A

inner temp
Balance between heat produced and environment

Make environment temp warm, skin to skin, and heat lamp to avoid hypothermia.

Give them a cap to wear on their head since they lose a lot of heat there

60
Q

Challenges to NB temps stability

A

Less subcutaneous fat

Thin epidermis/skin

No fat to cushion vessels (like head)

Poor posture, flaccid doesn’t hold heat in

LGA or 9ibs - does better w cold . They can overheat actually

SGA and preterm - less fat so less tolerate of cold . will need higher environmental temp

61
Q

Types of heat loss in newborns

A

Convection
Radiation
Evaporation
Conduction

62
Q

Small or large body surface compared to mass?

A

Large body surface area compared to mass

63
Q

Convection

Radiation

A

Air or draft that cools baby temp

Cooler objects NEAR the baby (not touching)
- nursery in center of hospital

64
Q

Evaporation

Conduction

A

Wet skin

Something directly in contact w baby skin - cold surface, hands, stethoscope

65
Q

Heat production in NB

Can they shiver?

A

Commonly done by moving around that increases metabolic activity

They can. It is uncommon but it is only happens with significant drop

66
Q

Chemical thermogenesis?

Where is brown fat located?

A

Non-shivering thermogenesis is caused by cool environment causes them to burn their brown fat (2-6% of body weight) for heat

Trunk over adrenals and chest

67
Q

Can brown fat be replaced?

A

No so we try to be conservative and protect them from burning it too fast

  • it’ll eventually be used up tho
68
Q

How long do newborns iron stores last?

A

4-6 months. Depends on moms prenatal care

69
Q

What gives the baby the rounded tummy?

A

Glycogen in liver - which is a good thing. Flat tummy means prone to hypoglycemia

70
Q

When does the liver conjugate the bilirubin?

A

Remember - the rbc turnover from infant to adult?
This applies here.
Bilirubin will conjugate once they are born (used to rely on mom)

71
Q

What is the newborns intestinal flora like?

Treatment

A

Intestinal flora will be sterile & so they can’t make pro-thrombin for vit K! And they are at risk for bleeding

Give vit k around 2 hrs of age
.5 mL IM
- clean skin first

72
Q

What if the infant isn’t given vit k?

A

Hemorrhage

or may not be able to do any procedure if baby needs it

73
Q

Conjugation of bilirubin means?

What must bilirubin pass through to be conjugated?

A

From going to fat soluble to water soluble bilirubin

Attach to albumin in order to pass through liver

74
Q

What happens to bilirubin once in liver?

A

GT enzyme attaches gluco chain to bilirubin for conversion to make it into water soluble now

75
Q

So what all is unconjugated bilirubin?

A

Fat soluble
Indirect
Pre-liver

76
Q

What all is conjugated bilirubin

A

Water soluble
Direct
Post liver

77
Q

indirect bilirubin level

direct?

When will jaundice appears when than tho?

A
  1. 8
  2. 2

indirect serum levels are greater 5-7.0

But remember - the baby is like this bc of the turnover. Not necessarily bc something is wrong. this is just the mechanism of breakdown of heme (recycle) and bilirubin

78
Q

How does jaundice present?

A

Head to toe first. And then check for dependent jaundice by turning them over

79
Q

Kerniticus

Consequence?

A

Hyperbilirubin that crosses over blood brain barrier. Brain cells turn yellow

Permanent irreversible brain damage!!! don’t get sued

80
Q

How to reduce hyperbilirubemia?

A

Feeding the baby. This causes them to poop it out and not get absorbed again
- so if mom says she is feeding the baby but the stool isn’t colored, then something isn’t adding up

81
Q

What is physiologic jaundice?

Do all aged newborns have albumin?

Increased absorption of bilirubin is caused by wat?

A

Accelerated destruction of fetal RBCs that increases bilirubin to the immature liver

No - premies have lack of albumin often. This makes it more prevalent

Increased absorption if they aren’t stooling - remember.

82
Q

What is pathologic jaundice?

How do we know?

What will levels be like?

A

When the patho is not right . Some condition probably caused it

Onset before 24 hrs (since physiologic is after this). A rapid onset

Patho jaundice has way higher levels than 12-14. And it lasts longer

83
Q

Patho reasons to cause Patho jaundice due to Unconjugated or Indirect bilirubin

A
Rh abnormality
ABO abnormalities
Sepsis
Cephalhematoma
Hemangiomas
Hypoxic insults
Polycythemia
Swallowed blood in delivery
Increased bilirubin recycling
84
Q

Explain Rh reason for patho jaundice

Unconjugated or Conjugated direct

A

RH - mom lacks protein on her rbc when she has an rh+ baby which causes her to produce antibodies that want to destroy baby rbc - which causes destruction of rbc and high bilirubin

Unconjugated or Indirect

85
Q

Explain ABO patho jaundice Unconjugated or Indirect

A

Mom is O and baby is A or B. And if you have O, then the antibodies attack here too.

86
Q

Explain Sepsis patho jaundice

Unconjugated or Conjugated

A

Sepsis decreases rbc and induces anemia.

Unconjugated

87
Q

Explain rbc disorders for patho jaundice

Unconjugated or conjugated?

A

Sickle cell
anemia
-Abnormal rbc get destroyed at faster rate

Unconjugated or Indirect

88
Q

Cephalhematoma for patho jaundice

Unconjugated or Conjugated?

A

(bleed in head from trauma near periosteum) - which breaksdown since it is outside the bloodstream and thus bilirubin is produced

Unconjugated or Indirect

89
Q

Hemangiomas for patho jaundice

Congugated or uncongugated?

A

Birth defect - big angiomas

Unconjugated
or indirect

90
Q

Hypoxic insults for patho jaundice

Unconjugated or conjugated?

A

Slows hepatic function and can’t convert bilirubin

Unconjugated or Indirect

91
Q

Polycythemia for patho jaundice

Unconjugated or Conjugated?

A

High rbc in blood than expected so more wil be destroyed

Unconjugated or Indirect

92
Q

Swallow blood in delivery for patho jaundice

Unconjugated or Conjugated

A

Happens in delivery and they just have to break it down and causes jaundice

Unconjugated or Indirect

93
Q

Increases bilirubin recycle for patho jaundice

Unconjugated or Conjugated

A

Because you don’t poop - maybe due to obstruction or not feeding baby

Unconjugated or Indirect

94
Q

Causes of patho jaundice wit Direct or Conjugated Bilirubin

A
Neonatal hepatits
Intestinal obstruction
Ischemic necrosis
Parenteral feeds
Metabolic disorders
Hematologic disorders
Ductal Disorders 
- biliary atresia
- tumors

It can pass through the liver but it is not excreted. And direct means the bilirubin that has passed . Excretion issue of post liver

95
Q

Which happens first? Breast feeding jaundice or breast milk jaundice

A

Breast feeding jaundice or poor breast feeding.

And then the breastmilk jaundice or composition

96
Q

Breast feeding jaundice

treatment?

A

Jaundice due to baby being dehydrated bc you aren’t feeding them enough and bilirubin concentration increases. 1st week of birth
Do 15 min on one breast and 15 min on another. Supply and demand
- stimulate the breast more!!!

97
Q

Breast milk jaundice

treatment?

A

Some moms have high free fatty acid and hormone levels and this causes baby bilirubin to be high
- rare but peaks 2-3 weeks later

  • You’ll give baby formula. But you will pump and dumb to keep your supply going
98
Q

How to asses for hyperbilirubemia or jaundice?

A

Blanch

Draw blood
- we draw levels of all newborns within 24 hrs & use bili tool

99
Q

What type of instruction do you absolutely have to give on jaundice?

And what else?

A

Verbal and WRITTEN bc of brain damage possibility due to kerniticus (cerebral palsy, retardation)
- avoid lawsuit by doing this

Have them sign the document for proof!! And document yourself

100
Q

How to check for jaundice in dark skin?

A

Mucous membranes
And baby will get sleepy

but do labs

101
Q

Treatment for hyperbilirubemia?

A

Feed them more

Phototherapy

Exchange transfusion

102
Q

Phototherapy

Exchange transfusion?

A

Blue light or fiber optic blanket that converts bilirubin in skin

Exchange transfusion gives blood and take blood. It specifically takes the rbc coated with antibodies to stop bilirubin production

103
Q

GI

What happens to blood glucose when cord id clamped?

What if baby is LGA or SGA?

A

Cutting cord makes blood glucose drop for first 1-2 hours.

Monitor LGA or SGA blood sugars . Feed them too or else their blood sugar drops to hypoglycemic

104
Q

GI

What reflexes are present at delivery?

A

Sucking, swallowing, empty stomach, and bowel sounds

105
Q

GI

what is the stomach capacity

A

Stomach capacity is tiny. Less than 30 mL. By day three it is 90 ml.

106
Q

GI

conditions?

A

Regurgitation

Projectile vomiting - from pyloric stenosis

GER - not the disease tho

107
Q

GI

what removes the mucus and reduces vomiting during transition period

A

DeLee suctioning

108
Q

GI

When should they urinate?
When should they stool?

A

urinate 24 hrs

stool 48 hrs

109
Q

Weight loss following birth

Do we expect all newborns to lose a little bit of weight?

A

Yes. Should be between 5-8%.
If it is more than 10% then lactation nurses step in especially if they haven’t gained the weight back by 14 days

  • lose, plateua, regain
110
Q

Weight loss following birth

What if the newborn never goes through a weight loss phase?

A

Fluid retention may be occurring and it is unusual

111
Q

If a newborn fails to lose weight in the first couple days, what is the reason?

A

Fluid retention

112
Q

Kidneys

What are the newborns nephron tubules like compared to adults?

How does the GFR affect excretion?

What will pee appear like?

A
