Treatment of the infant Flashcards
1
Q
The infant in Utero
A
- The Intrauterine Environment
- The First Trimester- 3months
- The Second Trimester-6 months
- The Third Trimester- 6-9 months
- Birth
- Newborn
2
Q
The womb
A
What happens in the womb is as important as
- external factors that interrupt development, disrupt development
- Normal completion of each phase depends on successful development of the previous phase
- one thing messes up and everything is messed up
- the nervous system is most at risk for injury at 3-5 months gestational age
3
Q
Uterine Environment
A
- The uterus is a contextual environment and motor outcomes (infants) are significantly impacted by it
- Aquatic environment (amniotic fluid)
- The intrauterine environment is gravity free, it is warm and the baby is protected
4
Q
1st trimester- 3 months- 12 weeks (8)
A
- Myelination of the nervous system occurs a few weeks after conception
- Vestibular system begins to form at 2 months of gestation
- major organs begin to develop in the 3 months of gestation
- Somatosensory system is active at 7.5 weeks of gestation
- 1st movement 7-8 weeks gestation
- Independent arm and leg movement 8-9 weeks
- Thumb sucking begins at three months in utero
- 42 days a sense of smell is developing in utero (6 weeks)
5
Q
2nd trimester 3-6 months (9)
A
- Exploratory hand to face movement begins
- Sneering and squinting has been observed at 14 weeks gestation
- Liquid breathing at 4 months-helps with growth of lungs
- Taste 15 weeks
- 17 weeks- response to light touch throughout the body
- 20 weeks- cochlea is functioning
- By the end of the 2nd trimester the baby is pushing legs against the womb and rolling
- A lot of babies who are premature come at this stage so they lose this extension flexion period that is important to development
- Mother’s voice dominants, hear blood flow, heart beat, gastrointestinal sounds
6
Q
3rd trimester 6-9 months (7)
A
- Multiple facial expressions
- By 36 weeks the vestibular system is active (not mature yet)
- Auditory system is well developed
- Babies are very visually driven, in the 3rd trimester visual system is established through the first 8 months gestation
- Brain controls body temp, breathing, and contractions of intestines
- Before full term the nerve fibers are hyperexcitable.
- Pre-term babies are much more irritable due to these excitable nerve fibers
7
Q
Birth (3)
A
- Baby experiences global compression during birth, very calming and organizing (doesn’t happen with c-section)
- Extends during birthing process (1st extension/ flexion activity)
- get initial processing of linear and vestibular information as they get out of birth canal
8
Q
- Newborn (3)
2. Abilities of newborn (3)
A
- Enter gravity- not used to it
- Need to have an active role or respiration, food, elimination, and body temperature
- Sensory experiences are no longer controlled by mom, they need to modulate themselves - Abilities of newborns
- They seek maternal contact, recognize smell, voice, face
- Imitate facial expressions
- Direct gaze
9
Q
Motor development red flags (6)
A
- Flat head- infant is in a stuck fixed position (baby is not moving enough) torticollis
- Baby can’t turn head to both sides
- Stiff
- Not meeting milestones
- Only use one side (dominant in only 1 side)
- Regression of skills-motor skills
10
Q
Sensory systems (4)
A
- Vestibular
- Somatosensory
- Visual
- Auditory
11
Q
Vestibular system (6)
A
- Tells us where our head is in space
- Disrupts balance
- Directly senses gravity
- Senses acceleration
- Reading, school age issues, stabilizes our eyes
- Arouses our nervous system
12
Q
Vestibular dysfunction (8)
A
- Poor head control
- Resisting movement
- Fear of movement
- Seek a surface, better on the floor
- Generally anxious and irritable
- Poor eye coordination
- Head is locked on their shoulders
- Scoot on their behinds- get a lot of input from this (indicative of a problem)
13
Q
Somatosensory system (5)
A
- temperature awareness
- Posture and movement
- Internal awareness of moving
- Touch
- Coordination of upright posture
14
Q
Somatosensory system dysfunction (5)
A
- Hypersensitive to touch
- Impoverished self touch
- Impoverished movement
- Difficulty grading their movement (one or all kind of thing) either run at full speed
- Motor planning difficulties
15
Q
Visual system 1 (10)
A
- Major learning system
- Organize spatial information
- Drives movement
- Helps us with our anticipation, adaptation, survival
- Babies eyes are not sensitive to light in the first month of life, their light detection threshold is 50X higher (higher tolerance)
- 1 week after birth, red, orange, yellow, and green
- 2-3 months sharper acuity, more teaming with their eyes
- 2-3 months can shift gaze from one object to another without moving their head
- 3 months 10X visual tolerance threshold
- 2-3 months add new items to the infants room or change crib position
