Q

Intrauterine Environment

A
  • TACTILE- constant proprioceptive input; smooth, wet, comfortable, boundaries
  • VESTIBULAR- maternal movements, dinural cycle, amniotic fluid creates gentle oscillating environment, flexed posture
  • AUDITORY- biological sounds, muffed environmental sounds
  • VISUAL- Dark; occasional red dim spectrum light
  • THERMAL- constant warmth consistent temperature

Q

Extrauterine Environment

A
  • TACTILE- Painful and invasive; dry cool air, medical touching, some social touching
  • VESTIBULAR- Flat postures, rapid position changes; influence of gravity; restraints due to equipment
  • AUDITORY- Loud, non-contingent, mechanical frequent harsh intermittent impulse noise
  • VISUAL-Bright lights, eyes unprotected; often no diurnal rhythm
  • THERMAL- environmental temperature variations, high risk of neonatal heat loss from thin skin and lack of subcutaneous fat

Q

Light exposure in the NICU

A

Fluorescent light exposure can lead to:

  • Chromosomal damage
  • Disruption of dinural rhythms
  • Over stimulation leading to physiological distress.

Pre-30 wk infants unable to close eyelids tightly or filter light properly.

Constant lighting affects development of natural circadian rhythms

16
Q

Environmental modifications for light

A

Environmental lighting should be:

  • Dimmed especially during night
  • Only use moderate lighting
  • Shield infant eyes with bedside draping or phototherapy eye mask or isolate cover
  • Focused lighting for procedures needing more light.
17
Q

Sound in the NICU

A
  • Constant environmental noise usually 50-90 dB (same as street traffic with light machinery)
  • Noise increases arousal and can increase physiological distress.
18
Q

Tactile exposure in the NICU

A

Frequent medical touch for procedures including ventilation, tube adjustments and suctioning.

  • Increased pain response in pre-term infants -> increased physiological distress.
  • Uncomfortable bedding
19
Q

Environmental modification of touch in the NICU

A

Let infant determine schedule
Avoid unnecessary touching-bathe every other day, check vitals from monitors, suction PRN not on schedule
Speak softly to infant prior to physical handling
Swaddling during painful procedures and baths

20
Q

Containment- calming strategies

A

The use of materials or humans to provide physical boundaries for the infant . I.e.: Z-flo fluidized positioners

21
Q

Kangaroo Care- Calming

A

Involves skin to skin contact with parent (better for non-ventilated infants); yields increased feeding time, reduction of physiological stress, and improved attachment

22
Q

Swaddling- calming

A

A type of containment that provides the infant deep pressure and simulation of womb positioning through the wrapping of a blanket around the baby

23
Q

Infant massage- calming

A

A technique in which parent provides gentle tactile stimulation or prolonged placement of the hands WITH the infant (Best for children 32 wks PCA

24
Q

Family education and collaboration

A

Stressors

  • health of infant
  • unfamiliar environment/technology
  • financial burdens
  • Transportation issues
  • Return to work
25
Q

family education

A

Vygotsky’s scaffolding method to train family to:

  • Detect physiological signs of stress
  • Reduce aversive sensory stimuli
  • Perform calming techniques
  • Position the baby therapeutically
  • Provide feeding instruction and support
26
Q

Standardized NICU assessments

A
  • Naturalistic observations of newborn behavior (NONB)
  • Assessment of Pre-term infant behavior
  • NICU Network Neurobehaviroal Scale
  • Infant behavioral assessment
  • Neonatal Oral motor assessment scales
  • Bayley infant toddler developmental motor assessment
27
Q

evaluation and interventions

A

-review preemie development notes

-

28
Q

intervention

A
  • reflex testing often unnecessary with early preemies
  • muscle tone- hypotonia typical for preemie, may be affected by arousal state or medication
  • Therapeutic positioning (without positioning infant presents with W-posturing of arms, froglike posturing of legs, and asymmetrical head position.
29
Q

Therapeutic Positioning

Plagiocephaly

A

Development of abnormal head shape in infants resulting from externally enforced molding surfaces (prolonged position of head towards one direction)

30
Q

Therapeutic positioning

Brachycephaly

A

Flattening of the back of the head due to prolonged supine position

31
Q

Therapeutic positioning

Scaphocephaly

A

Narrowing of the head along the sides due to progressive time spent with head turned to one side while in prone position (preemies lack the musculature to extend neck and freely move head so it remains in this position

32
Q

therapeutic positioning

A
  • Increase flexion positing (fetal position)
  • Sidelying position supported with snuggle wraps and blanket rolls
  • Sleeping position- safest sleeping position to avoid SIDS is supine, but at risk for brachycephaly
  • Watch for extensor tone in neck due to trach and vent tubing- eventually work on neck flexion as these are removed.
33
Q

Nesting-

A

Place infant in flexed position inside a concave space made by blankets and towel rolls with high, steep boundaries.

  • soft, secure surface- Gel mattress to relieve pressure
  • Commercial products will reduce positioning errors by different caregivers
34
Q

Feeding in the NICU

A

-Parent education for increasing breast or bottle feeding.

Supportive positioning
Nipple selection
Oral motor stimulation for the older preemie
Complications of feeding- reflux – suck/swallow/breathe develops at 34 wks gestation

35
Q

Discharge planning from the NICU

A

Premature infants are at risk for developmental delay and other health complications.
- Most discharge criteria include that they baby can: breath independently or that caregiver be independent with vent care, Feed well by bottle/ breast or be independent with tube placement and feedings, maintain adequate temperature and weight.
