Study Notes
Neonatal Nervous System
- The newborn's nervous system controls functions like hunger, thirst, and satiety, balanced by hypothalamic centers. It also influences sucking and swallowing.
- Neonates are born with active sensory pathways (smell, taste, sight, and sound), used in utero. They learn by processing and responding to sensory stimuli.
- Movements can be reflexive or volitional, under control of the motor cortex. Myelination of nerve tracts gradually leads to better motor control.
- Sensory stimulation supports skeletal muscle development and neural connections via new dendrites and interneurons.
Reflexes
- Autonomic reflexes are involuntary motor behaviors, crucial for safety and survival, often within the spinal cord.
- Assessing reflexes helps evaluate the integrity of the neurological system.
- Grasping and Moro reflexes are used to assess central nervous system development in newborns.
- Absence of reflexes may suggest brain damage, asphyxia, neurological issues, or drug exposure.
- Some primitive reflexes may reappear in adulthood, potentially due to neurological problems.
Neurological Examination
- The Apgar score assesses the baby's response to handling and tone, as well as limb movements and alertness.
- Level of consciousness (alertness and interaction) and adaptation to temperature are also assessed, along with cry tone and its clarity.
- Pain perception can differ, making accurate assessment difficult.
- Feeding responses and facial dysmorphism (facial anomalies) are examined.
- Eye movements are observed for reaction to light and ability to fixate, providing potential neurological markers.
- An anal wink assesses the strength of the anal sphincter.
Behavioural States
- Normal newborn posture involves flexion with the head centered, and alternating arm and leg movements.
- Jerky movements (startle/myoclonic jerks), when limbs are moved, are expected and normal.
- Traction response (ability to hold a seated position) is observed.
Sleep Patterns
- Normal term newborns cycle through various sleep stages (e.g., active, light, and deep sleep).
- Approximately 50 minutes of sleep is spent each hour, with roughly half of that time in quiet sleep.
- Sleep patterns are not typically tied to a light-dark cycle, although this can vary.
Key Neurological Alarm Signals
- Potential red flags include persistent irritability, feeding difficulties, asymmetrical posture and movement, floppiness, abnormal cries, setting sun eyes, convulsions, respiratory difficulties, or unusual apathy, or hyperactivity.
- These rare signals require urgent referral and investigation.
Next Steps
- Discuss any concerns with a practice supervisor and consider possible referrals as necessary.
- Communicate findings carefully with parents using a sensitive approach.
- Thorough documentation of observations is necessary.
