Q

What is the routine examination of the newborn?

A
  • Birthweight and BW centile - gestational age noted
  • General observation
    • Appearance, posture, movements, plethoric or pale, jaundice, rashes
  • Head circumference, fontanelle, face, red eye reflex, palate, clavicles
    • Cephalohematoma = benign - margins of skull sutures → resolve over few months
    • Caput Succedaneum = crosses Suture lines, resolve over few days, start at birth
    • Subaponeurotic/subgaleal haemorrhage = diffuse, boggy swellings with hypovolaemia and shock
    • Tense fontanelle = raised ICP, caput succedaneum, cephalohematoma, chignon → cranial USS
    • Depressed fontanelle = dehydrated
  • Hearing test
  • Breathing, chest wall movement, HR, abdomen, cord, hernias, pectus
    • Fall off by 40 days
  • Femoral pulses, genetalia, anus
  • Muscle tone, whole of back and spine, DDH, hands and feet
    • Fully dorsiflex the foot to touch lower leg to see if true talipes equinovarus

Q

Describe hearing tests given to neonates?

A
  • 1st line: Evoked Otoacoustic Emission (EOAE) Testing – all babies receive this test!
    • Sound emitted into earphone to evoke an echo or emission from the ear if cochlear function is normal
  • 2nd line: Automated Auditory Brainstem Response (AABR) Audiometry
    • A computer will analyse the EEG waveforms evoked in response to a series of clicks
    • Indications
      • Fails EOAE
      • Too young for a regular test
      • Severe learning difficulty
