Neonatal Examination

The newborn and infant physical examination (NIPE) is a screening programme performed within 72 hours of birth. It focuses on eyes, heart, hips, and testes, alongside a comprehensive systems examination.

Key Facts

NIPE (Newborn and Infant Physical Examination): Screening at <72 hours and 6-8 weeks; focuses on eyes, heart, hips, and testes Red reflex: Absent or white reflex — urgent ophthalmology referral (retinoblastoma, congenital cataract) Heart murmurs: Present in ~1% of neonates; most are innocent (soft systolic); refer if loud, pan-systolic, diastolic, or associated with cyanosis/signs of HF Barlow and Ortolani tests: Screen for developmental dysplasia of the hip (DDH); positive = USS hip at 2 weeks Undescended testes: Affects ~3-5% of term boys; most descend by 3-6 months; if not palpable by 6 months — referral for orchidopexy by 12 months Vitamin K: Offered to all newborns — IM (single dose) or oral (3 doses) — prevents haemorrhagic disease of the newborn (VKDB) Newborn bloodspot screening: At day 5 — screens for PKU, congenital hypothyroidism, sickle cell disease, CF, MCADD, and other IEMs Apgar score: Assessed at 1 and 5 minutes; 0-3 = severe depression, 4-6 = moderate, 7-10 = normal

Overview

Key Facts

The neonatal examination is a key screening opportunity to identify congenital abnormalities and conditions that benefit from early treatment. The NIPE programme is a national NHS screening programme.

Epidemiology

Approximately 650,000 babies are born in England each year. Congenital heart disease affects ~8 per 1,000 live births. DDH affects ~1-3 per 1,000. Undescended testes affect ~3-5% of term boys. Congenital cataracts affect ~3 per 10,000.

Aetiology

The NIPE programme screens for conditions where early detection improves outcome:

  • Eyes: Congenital cataracts, retinoblastoma
  • Heart: Congenital heart disease (structural)
  • Hips: Developmental dysplasia of the hip
  • Testes: Undescended testes (cryptorchidism)

Pathophysiology

DDH: Spectrum from acetabular dysplasia to complete dislocation. Risk factors include breech presentation, family history, female sex, first-born, oligohydramnios. Early detection allows Pavlik harness treatment (splintage) which is successful in >90% if started before 6 weeks.

Congenital heart disease: Structural defects in cardiac development. Critical CHD (duct-dependent) may present with cyanosis or collapse as the ductus arteriosus closes in the first days of life.

Clinical Presentation

Systematic Neonatal Examination

  • General: Colour, tone, activity, cry, dysmorphic features
  • Head: Fontanelles (anterior — closes 12-18 months; posterior — closes 6-8 weeks), moulding, cephalhaematoma, sutures
  • Eyes: Red reflex (bilateral), pupil size, discharge
  • Mouth: Palate (feel for cleft), tongue-tie, natal teeth
  • Cardiovascular: Heart rate, rhythm, murmurs (position, grade), femoral pulses (absent/weak → coarctation), pre- and post-ductal SpO2
  • Respiratory: Rate, symmetry, grunting, recession, breath sounds
  • Abdomen: Organomegaly, masses, umbilicus
  • Genitalia: Testes (palpable, position), hypospadias, ambiguous genitalia
  • Hips: Barlow (dislocatable?) and Ortolani (reducible?) tests
  • Spine: Midline defects (dimple, tuft of hair, swelling → spinal dysraphism)
  • Skin: Birthmarks, rashes (erythema toxicum, milia, Mongolian blue spots)
  • Neurology: Tone, posture, primitive reflexes (Moro, grasp, rooting)

Red Flags

  • Absent red reflex — retinoblastoma or cataract; urgent ophthalmology
  • Central cyanosis — congenital heart disease until proven otherwise
  • Absent femoral pulses — coarctation of the aorta
  • Ambiguous genitalia — endocrine emergency; do NOT assign sex
  • Midline spinal defect — USS spine before 6 weeks (or MRI after)
  • Bilious (green) vomiting — malrotation until proven otherwise

Differential Diagnosis

FindingPossible CauseAction
Absent red reflexCongenital cataract, retinoblastomaUrgent ophthalmology
Heart murmurInnocent (50%), VSD, PDA, ASD, ToFEcho if concerned
Absent femoral pulsesCoarctation of aortaUrgent echo
Hip click/clunkDDHUSS hips at 2 weeks
Undescended testisCryptorchidismReview at 6-8 weeks; referral if not descended
Jaundice <24hHaemolytic disease (Rh/ABO)Urgent SBR + Coombs

Diagnosis / Investigation

Bedside

  • Pulse oximetry screening: Pre-ductal (right hand) and post-ductal (either foot) SpO2; difference >3% or SpO2 <95% → echocardiography
  • Weight: Birth weight, daily weights if concerns
  • Blood glucose: If risk factors (SGA, LGA, maternal diabetes)

Bloods

  • Newborn bloodspot screening (day 5): PKU, congenital hypothyroidism, sickle cell, CF, MCADD, and 5 other IEMs
  • SBR (serum bilirubin): If jaundice <24h or clinically significant
  • Blood group and DAT (Coombs): If early jaundice

Imaging

  • USS hips: Indicated if positive Barlow/Ortolani, risk factors (breech, family history, foot deformity)
  • Echocardiography: If murmur with features of concern, absent femoral pulses, or abnormal pulse oximetry
  • USS spine: Before 6 weeks if midline defect (sacral dimple with concerning features)

Special Tests

  • Newborn hearing screening (NHSP): Automated auditory brainstem response (AABR) or otoacoustic emissions (OAE) — within first few weeks

Management

Non-pharmacological

  • NIPE examination: Within 72 hours and repeated at 6-8 weeks
  • Breast/bottle feeding support: Establish feeding; weight check at day 5
  • Skin-to-skin contact: Promotes bonding, thermoregulation, breastfeeding
  • Safe sleeping advice: Back to sleep, feet to foot of cot, no co-sleeping with risk factors (SIDS prevention)

Pharmacological

  • Vitamin K: IM 1mg (single dose) or oral 2mg at birth, 1 week, 4 weeks — prevents VKDB
  • Hepatitis B vaccine: Within 24 hours if mother HBsAg positive + HBIG
  • BCG vaccine: For babies at increased risk of TB

Referral Criteria

  • Absent red reflex — urgent ophthalmology (within 2 weeks)
  • Suspected CHD (murmur + cyanosis/absent femorals/abnormal SpO2) — urgent echo
  • Positive Barlow/Ortolani — USS hips at 2 weeks
  • Undescended testis — review at 6-8 weeks; surgery referral by 6 months
  • Ambiguous genitalia — endocrine/DSD team urgently
  • Suspected genetic syndrome — clinical genetics

Prognosis

  • DDH: >90% success with Pavlik harness if detected early (<6 weeks); late detection requires surgery and has worse outcomes
  • CHD: Depends on lesion; duct-dependent lesions need prostaglandin to maintain ductal patency; surgical outcomes greatly improved
  • Undescended testis: Spontaneous descent in ~70% by 3 months; orchidopexy before 12 months reduces infertility and malignancy risk
  • Congenital cataracts: Good visual outcome if operated within first 6-8 weeks of life
  • Newborn screening: Early treatment of PKU, hypothyroidism, and sickle cell disease dramatically improves long-term outcomes
