Examination of the NewbornExamination Part 1:
Eyes, heart, hips and testes
Chris Kingsnorth
Before We Begin
Overview
• 4 presentations:
1. Introduction and pre-examination2. Examination part 1: Eyes, heart, hips
and testes3. Examination part 2: Top-to-toe4. Post-examination
Overview
• Examination of the NIPE’s main 4 areas of focus: Eyes, heart, hips +/- testes
• Common pathologies• Practical tips
Will be integrated into top-to-toe examination in Examination Part 2
General Principles of Examination
• Don’t be scared of the baby!• Be flexible in order examining based on baby’s
behaviour/ state of undress• Keep baby warm• Involve parents; explain examination and
findings• If unsure about findings, ask a senior• Be prepared to change nappies
Eyes
Examining the Eyes
• Assessing structure, not function• 2 main pathologies:
1. Congenital cataract2. Retinoblastoma
• Other features may suggest abnormalities (e.g. size/ shape/ position of eyes and optical structures)
Examining the Eyes: Risk Factors
• Birth wt <1500g• Gestational age <32 weeks• FHx of any childhood eye disorder inc.
congenital cataract/ glaucoma/ retinoblastoma
• Maternal infections during pregnancy e.g. rubella, toxoplasmosis, HSV
• Size, shape and symmetry of orbits and globes• Opening both eyes?• Squint?• Discharge/ crusting?• Shape + symmetry of irises
Examining the Eyes: External Structures
• Reflection of light from retina• Ophthalmoscope set to largest white disc• Shine into eyes from 15cm• Look for red reflex• May need gentle encouragement to open
eyes
Examining the Eyes: Red Reflex
• Absence of reflex suggests congenital cataract
• White reflex suggests retinoblastoma
Examining the Eyes: Abnormal Red Reflex
Examining the Eyes: Summary and Referral
Facts About 200 children a year are born in the UK with congenital cataract in one or both
eyes. Cataract is the largest treatable cause of visual loss in childhood in the UK.
Screening process
The screen is undertaken in a darkened room, with the baby in a supine position or, if necessary, over the parent’s shoulder.
The screen covers: a general examination of the eye, checking for the red reflex, and checking eye movement.
Referral and follow up
Babies with a positive screen should be referred for expert consultation by two weeks of age (newborn examination); by 11 weeks of age (6-8 week examination).
Parents should be given information about the suspected condition.
Heart
Examining the Heart
• Severe congenital heart defects often picked up antenatally or within minutes of birth
• Mainly assessing for murmurs which may warrant further investigation
• Includes assessment of CVS in general
Examining the Heart: Risk Factors
• FHx of congenital heart disease• Maternal conditions e.g diabetes, SLE• Rubella exposure during 1st trimester• Medications e.g. lithium therapy• Conditions inc. Down's, Noonan's and
Marfan's syndromes
Examining the Heart
• Cyanosis?• Heart rate • Pulse rate, rhythm and volume • Heart sounds + murmurs• Femoral pulse presence, volume + symmetry
Examining the Heart: Summary and Referral
Facts
Congenital cardiac defects are a leading cause of infant death. Critical or serious congenital cardiac malformations are found in approx. 6-8 in 1,000
newborn babies. One in 200 babies has a heart problem that requires treatment. Risk factors include a family history of congenital heart disease; maternal diabetes or
systemic lupus erythematosus; exposure to rubella during the first trimester; certain medication taken during pregnancy such as lithium therapy; also syndromes such as Down’s, Noonan’s and Marfan’s.
Screening process
The screen consists of general observation ofthe baby’s colour and respiration, palpation and auscultation of the heart and chest area
Rountine use of pulse oximetry as an adjunct to the full newborn physical examination is currently being piloted (2015)
Referral and follow up
Babies with a positive screening examination should have pulse oximetry to aid diagnosis and be referred to a senior paediatrician or other relevant expert urgently depending on the condition (newborn) or for 6-8 week old babies, referred at the time of the examination to a senior paediatrician or other expert
Parents should be given information about the suspected condition
Hips
Examining the Hips
• Examining for Developmental Dysplasia of the Hip (DDH)
• 2 presentations:
1. Hip already dislocated (congenital dislocation)
2. Hip can be dislocated easily (hip instability)
Examining the Hips: Risk Factors for DDH
• 1st degree FHx of hip problems in early life• Breech presentation @ 36/40, irrespective of
presentation at delivery and mode of delivery• Breech delivery if < 36/40
In multiple births, if any of the above risk factors are present, all babies should be referred for USS to identify which may be
affected
Examining the Hips: Barlow and Ortolani Manoeuvres
• Can be distressing for parents to watch• Examine one hip at a time
Examining the Hips: Barlow’s Manoeuvre
• Test for hip instability (i.e. can hip be dislocated?)
• Adduction of hip with posterior pressure on thigh
• +ve Barlow test = clunk as femoral head comes out of acetabulum
Examining the Hips: Ortalani’s Manoeuvre
• Test for congenital dislocation (i.e. hip already out of socket); also relocates hip if dislocated during +ve Barlow manouvre
• Abduction of hip with anterior pressure on thigh
• +ve Ortalani test = clunk as previously displaced head of femur falls into acetabulum
Examining the Hips: Summary and Referral
Facts
One or two in 1,000 babies have hip problems requiring treatment Major risk factors include a first degree family history of hips problems in early life, breech
presentation at 36 weeks of pregnancy or breech delivery at any gestation Undetected DDH or delayed treatment can result tin long term complications
Screening process
The screen is undertaken on a flat firm surface and the baby should be undressed
Referral and follow up
Babies with a positive screen (abnormal clinical examination) should be referred for urgent ultrasound and expert consultation. Newborns should be seen by 3 weeks of age, 6-8 week old babies should be seen by 10 week of age
Parent should be given information about the suspected condition
Testes
Examining the Testes
• To identify boys with unilateral or bilateral undescended testes (cryptorchidism)
• If missed can have detrimental effect of future fertility
• Bilateral undescended testes may be a sign of endocrine disease, therefore considered more serious
Examining the Testes: Risk Factors for Cryptorchidism
• 1st degree FHx (father or sibling) of cryptorchidism
• Low birth wt/ small for gestational age• Pre-term delivery
Examining the Testes
Inspection:
•Size/ shape/ symmetry of testes•Scrotal rugae (‘wrinkles’ on scrotum; lack of these suggests maldescent of testes)•Urethral meatus and hypospadias
Palpation: Are both testes palpable inside the scrotum?
Examining the Testes: Summary and Referral
Facts 1-2 in 100 baby boys have problems with their testes that require treatment Risk factors include first degree family history of cryptorchidism; low birth weight; small
for gestational age or pre-term delivery
Screening process
The screening examination consists of observation of the scrotum and penis, and palpation of the scrotal sac
Referral and follow up
Babies with bilateral undescended testes should be referred to a senior paediatrician within 24 hours of examination (newborn)
Babies at 6-8 weeks with bilateral undescended testes should be seen by a senior paediatrician within two weeks of examination
Babies with unilateral undescended testis should be reviewed at 6-8 weeks examination (newborn)
Babies with unilateral undescended testis at the 6-8 week examination should be reviewed by the GP between 24-30 weeks of age.
