Q

What is premature rupture of membranes (PROM)?

A

When the water breaks early

Q

What is primary apnea?

A

When the infant has undergone in-utero stress, it is self limiting and a reversable condition.

  • Usually cord problems
  • lasts a few seconds
  • may require mild to mod stimulation to initiate respiration
  • may be accompanied by mild bradycardia

Q

What is secondary apnea

A

when respirations will not resume spontaneously
- requires PPV
- HR may be severely bradycardic

29
Q

If fetal stress in utero has been observed, and the babe is not breathing. what can you assume?

A

secondary apnea

30
Q

How do you identify primary apnea?

A

Fetal heart rate, when babe is stimulated they will breath in response.

  • usually associated with cord problems
31
Q

How do you differentiate primary and secondary apnea?

A

babes w/Secondary apnea don’t have a respiratory response. You will need to take action.

32
Q

What is the most common cause of bradycardias in kids?

A

Ventilation problems

33
Q

What do you run through if HR does not increase?

A

MR SOPA

34
Q

What should you have before compressions start?

A

Artificial airways like ETT

35
Q

What drug can be given to help stimulate babes?

A

Caffeine

36
Q

What are signs of resp. distress in neonates?

A
  • Retractions
  • Grunting
  • Nasal Flaring
  • Increased O2 requirements
  • Cyanosis
  • Tachypnea (RR >60 bpm)
37
Q

What is Grunting a sign of in Neos/infants?

  • Interventions?
A

A sign of resp. distress where peds/babes are trying to create their own PEEP.

  • To maintain FRC in babes
  • Interventions would be CPAP or increase
  • try to prevent alveolar collapse?
38
Q

How long are infants obligate nose breathers?

A

until aprox 4 months of age.

  • small nasal airways = high obstruction risk
39
Q

Why are infants at higher risk of developing hypoxia?

A
  • Higher metabolic rate (double adults)
  • Lung volumes are smaller, less SA (alveoli) for exchange, and muscles tirer faster.
  • Chest wall more compliant (easily collapse) and bc ribs are horizontal, they can’t expand as much.
  • Premature nervous system, Neos easily fall into bradycardias (rate dependent) leading to hypovolemia which easily leads to shock-decreased perfusion
40
Q

What are cardiac causes that would lead infants to be hypoxic?

A

Heart rate and stroke volume

  • LV are underdeveloped and can’t compensate by increasing stroke volume
  • hypovolemia decompensate quicker (due to reduced pumping)
41
Q

What are the 4 conditions of a routine delivery (babe given to mom instead of warmer)

A
  • Infant born at full term gestation
  • Amniotic fluid clear with no evidence of infection
  • crying or normal breathing
  • good muscle tone
42
Q

Why do body temperatures fall rapidly in infants at neutral thermal environments?

A
  • They haven’t developed the ability to regulate temp. (they can’t shiver yet aka ).
  • Haven’t developed brown fat
  • SA to body mass ratio 4x of an adult, but ability to increase heat production in 1/3 of an adult
  • labile temp. from intrautrine to extra uterine
43
Q

What is thermogenesis?

A

Regulating heat by shivering

44
Q

How to infants manage tempature?

A

They produce brown fats to maintain.

  • If brown fat isn’t produced, babes have to be put into a ziplock bag for thermoregulation.
45
Q

Physiological affect if infants can’t regulate heat?

A

Heat loss releases epinephrine

  • Epi release causes hypoglocemia and high lactate bc of elevations in PVR and SVR
46
Q

Target Temperatures in a newborn

A

36.5-37 degrees Celsius

47
Q

What are consequences of cold stress in a newborn?

A

Increased O2 and calory uptake to compensate for heat loss. Resulting in…

  • Depletion of brown fat and glycogen (energy stores)
  • Increase CO2 and lactate
  • Norepi release -> raises PVR and SVR causing metabolic acidosis and hypoglycemia.
48
Q

What should room temperature be for babes in the NICU?

A

23-25 degrees C to maintain NTE. The NICU is hot.

49
Q

How are baby temperatures measured?

A

skin temperature probes

50
Q

What are 4 mechanisms of heat loss?

A
  • Evaporation
  • Convection
  • Radiation
  • Conduction
51
Q

What are 2 mechanisms of heat loss that deal with proximity and not contact?

A

Radiation and conduction.

52
Q

How do you prevent heat loss from conduction?

A

Occurs when body heat is lost to a cooler contact surface so.

  • keep stethoscope under warmer
  • keep babe in warm spots
53
Q

How to prevent heat loss to evaporation?

A

Wrap the baby up in blankets or in a bag

54
Q

What devices are used to regulate temperature?

A

Radiant warmer and close isolette

55
Q

Functions of Radiant Warmer

A

Used for overhead warming
- Body temp can be maintained via servo mode, with skin probe.
- panda

56
Q

Functions of Closed Isolette?

A

Used for low birth weight infants w/temp instability
- maintains a constant body temp by using either a servo controlled skin probe, air temp control device, or air temp probe.
- should be double walled or heat shielded
- Unicorn/giraffee

57
Q

For micropremature infants (<28wks), what should you do instead of dry stimulation?

A
  • Wrap in polyurethane bag to prevent heat loss and reduce risk of IVH.
  • Adjust body position to reduce risk of IVH (germinal matrix is mature and at high risk of bleeds)
  • Look for bulging fontanels (sign of high ICP and potential IVH)
58
Q

How should you adjust body position of premature infants (<28wks) at delivery?
- why would you do it?
- **ask someone why supine is preferred to proning)

A

first 72hrs, supine, neck extended, midline.
- prevents IVH by preventing abrupt changes in cerebral perfusion, prompting neuroprotection.

59
Q

Which mechanism of heat loss associated with heat loss to the surrounding air?

A

Convection

60
Q

Which mechanism of heat loss is associated with heat loss through fluid evaporating from the skin?

A

Evaporation

61
Q

Which mechanism of heat loss is associated with heat loss from an infant to a colder nearby object?

A

Radiation

62
Q

Which mechanism of heat loss is associated with colder object that the infant comes in contact with?

A

Conduction

63
Q

What is the gold standard for determining Gestational Age?

A

Prenatal sonography

64
Q

What are intrapartum risk factors?

A

Factors/conditions that could pose a risk to the mom and babe.

  • maternal health conditions
  • fetal positioning
  • Previous C-sections
  • preterm labor
  • Placenta abruption
  • Meconium stained amniotic fluid
65
Q

Why is epidural pain control not considered a intrapartum risk factor

A

Because its a med intervention used to alleviate pain and discomfort during the intrapartum period rather than a risk factor that poses a potential harm or complication.

  • Helps women manage the discomfort associated with contractions and childbirth.
  • Epidurals are a well-established and effective method for reducing pain and improving the overall birthing experience for many women.
66
Q

Ideal fetal scalp pH is what?

A

anything > 7.25

67
Q

What does the lung bud emerge from?

A

Pharnyx

68
Q

Why could Preterm infants be unable to maintain thermal homeostasis?

A
  • Lack brown fat
  • No ability to shiver
  • High body surface area to body weight area
