How is chronic lung disease of prematurity managed?
prophylaxis / preventions: give mum IM steroids if <34 weeks and consider between 34-36 weeks
Respiratory support: A-E approach - high flow oxygen via nasal cannula or incubator oxygen - if >2L of oxygen then humidify CPAP Invasive ventilation Give surfactant
medications:
- dexamethasone if >/= 8 days and on ventilator
- caffeine citrate if =/<30 weeks corrected gestational age
- nitric oxide: only if pulmonary hypoplasia or pulmonary HTN
How are cleft lip and palate managed?
feeding: early assessment and intervention may be needed e.g. NG tube / specialised teat / dental palate
MDT team for CL / CP:
- early referra
potential airway problems (Pierre-Robin sequence) may occur and need management
pre-surgical: lip taping, oral appliances or pre surgical nasal alveolar moulding may be needed to narrow the cleft
surgery: at 3 months for CL, between 6-12 months for CP
seech and language therapy
may requires orthodontists
How is CMV in the newborn treated?
Urine for CMV and viral PCR
- definitive test for congenital CMV id done in the first 2 weeks of life
Barrier nursing - as CMV is shed in the urine and body secretions
CMV usually has no long term implications
Life threatening infection: IV ganciclovir or Oral valganciclovir
CNS infection: IV ganciclovir or oral valganciclovir (have been shown to prevent long term hearing loss in the babies)
How is a congenital diaphragmatic hernia in children managed?
In utero
o In utero surgical repair, and tracheal plugging or ligation have been attempted
- Outcomes have been variable
Resuscitation after birth o Intubate o Positive pressure ventilation o Wide-bore NG tube (8 Fr) - Aspirate and then leave on free drainage
o IV access
- Sedation and muscle relaxation
o HFOV and exogenous surfactant
- If respiratory failure severe
o Persistent pulmonary hypertension of the New-born
- Common and may require iNO
Surgery o Diaphragmatic defect is closed with primary repair or synthetic patch o Only done after baby is stabilised o Post-operative support may include: - HFOV - iNO - ECMO
How is conjunctivitis in the newborn managed?
all acute cases of bacterial conjunctivitis require an urgent same day referral to an ophthalmologist
Mild bacterial conjunctivitis:
o Chloramphenicol eye drops
• Moderate-severe bacterial conjunctivitis:
o Systemic antibiotics
- Chlamydial: Oral erythromycin
Gonococcal: Single dose of parenteral cefotaxime/ ceftriaxone
- Pseudomonal: Gentamicin eye drops plus systemic antibiotics
• Viral: no specific antiviral, may use topical antihistamine and artificial tears to relieve itching
How is Down syndrome managed?
Urgent PCR for trisomy 21
Full clinical exam especially of CVS
Echocariogram FBC and Blood film Hearing screening test SALT Opthalmologist MDT approach
Support: Down’s Syndrome Association
genetic counselling and early intervention therapies (physiotherapy and occupational therapy for fine motor skills)
individualised educational plan
monitor for associated problems
Why is an echocardiogram done in a suspected down syndrome case?
if abnormal send to cardiologist,
congenital heart defects very common, 45% of Down Syndrome babies have it, mainly AVSD
Why is a blood film and FBC done in a suspected case of Down Syndrome?
10% have transient abnormal myelopoiesis, so baby is at higher risk of leukaemia
polycythaemia also common and need to be excluded
refer to haematologist if suspicious
Which early intervention therapies are suggested in down syndrome?
physiotherapy
occupational therapy
What conditions needs to be monitored for in Down syndrome?
Duodenal atresia o Hirschsprung disease o Coeliac disease o Hypothyroidism o Epilepsy o Hearing and visual defects o Periodontal disease o Atlantoaxial instability
How is GBS prevented?
intrapartum ABx (IV benzylpenicllin / clindamycin if allergy) in women who have:
- a previous baby with an invasive group B streptococcal infection
-group B streptococcal colonisation, bacteriuria or infection in the current
pregnancy
Which medications are given if there are clinical signs of GBS?
Penicillin and gentamicin
If CSF fluid is positive for GBS, how is this managed?
Benzylpenicillin 50mg/kg every 12h (at least 14 days)
and Gentamicin in starting dosage of 5mg/kg every 36h (for 5 days)
- dose adjustments made based on clinical judgement
How is haemolytic disease of the new born prevented?
maternal Anti-D
- at 28 weeks, 34 weeks and birth
-rarely can be given as a single 1500iU between 28-30 weeks
How is haemolytic disease of the newborn managed in newborns?
Resuscitation
- A to E approach particularly if preterm, anaemic or hydropic
o Exchange transfusion
- Indicated if:
• Bilirubin rapidly rising (>8-10 μmol/l/hr) despite adequate phototherapy
• Severe hyperbilirubinaemia insufficiently responsive to phototherapy
and supportive care
• Significant anaemia (Hb <100 g/l)
o Phototherapy
- Do not delay if baby thought to clinically have significant jaundice
• Transcutaneous bilirubin measurement can be taken to confirm/ if
unsure
o IVIG
- Only for immune haemolysis
How is haemolytic disease of the newborn followed up?
check for late anaemia at 4-6 weeks
- consider folate supplementation to protect against this
hearing screen
counsel parents on recurrence in future pregnancies
Which neonates require the Hepatitis B vaccine?
Acute: supportive care
HBsAg positive should receive:
- monovalent hepatitis B vaccine within 24h of birth (also at 4 weeks and 1 year)
- hexavalent (6in1) at normal times
Which neonates require HBIG?
- If mum is HBsAg positive (even if HBeAg negative)
- if mum had acute hepatitis B during pregnancy
- mother had an HBV DNA level equal or above 1/10^6 in any antenatal sample during current pregnancy
HBIG should idealy be given simultaneously with Hep B vaccine but a different site
How is HSV in the neonate managed?
if mum has primary disease 6 weeks before delivery then elective c-section is indicated
if primary infection earlier in pregnancy then offer prophylactic oral aciclovir from 36 weeks until delivery
aciclovir / valaciclovir can be given prophylactically to baby during the ‘at-risk’ period
How is mild HIE managed?
Resucitate
Therapeutic hypothermia
ventilation - consider respiratory support early
Ensure PaCO2 4.5-6 kPa
Cardiovascular:
- consider invasive monitoring of BP and inotropic support early
- consider dobutamine to maintain BP ( > 40 MABP in term infants)
Fluids:
- 60-80% of maintenance
monitor urine output
How is moderate HIE managed?
- Prompt treatment of seizures
• EEG to be considered - Maintain normoglycaemia (2.6-8.0 mmol/l)
- Treat hypocalcaemia if present
- Measure LFTs to assess liver injury
- Ensure IM phytomenadione (vitamin K) is given
- Monitor coagulation
- Withold feeding for at least 48 hours (due to increased risk of NEC)
How is severe HIE managed?
Cranial ultrasound scan
• Important in excluding other causes of encephalopathy e.g.
haemorrhage
-MRI brain
-Consider switching to palliative care
• Continuing efforts with intensive care may be futile
• Requires MDT approach and discussion with family
How is Listeria monocytogenes infection managed?
Amoxicillin and gentamicin (if blood cultures or CSF come back positive for Listeria)
How is meconium aspiration treated?
Use BMJ best practice flow chart
If normal term infant with meconium-stained amniotic fluid but no history of GBS, observation is recommended
• If there are risk factors or laboratory findings that are suggestive of infection, consider antibiotics:
o IV ampicillin AND gentamicin
- Oxygen therapy and non-invasive ventilation (e.g. CPAP) may be used in more severe cases
- Boluses of surfactant and inotropes given in moderate cases
