- Blood culture and microbiological swab to determine organism
For orbital cellulitis - CT with contrast (shows inflammation of orbital tissues, sinusitis)
Treatment
Orbital cellulitis –> IMMEDIATE ADMISSION
Broad spectrum IV antibiotics
- Co-amoxiclav/Flucloxacillin
(Penicillin allergy - clindamycin)
Squint/Strabismus
Investigations
Treatment
Investigations
- Cover test - ask child to focus on an object and cover one eye if there is refixation, strabismus is present. (refixation is in the opposite direction of the tropia e.g. eye moves inward in exotropia)
- Hirschberg test (corneal light reflex test)
–> Light should be in the same position in both eyes.
Tx
- Refer to ophthalmology
For amblyopia –> Occlusion of the normal eye with an eyepatch
For VA –> correct with spectacles or contact lenses
Definitive for strabismus –> Extraocular muscle surgery
Atrial septal defects
Investigations
Treatment

Tx
Observation
Surgical closure of the defect
Ventricular septal defects
Investigations
Treatment
Investigations

Tetralogy of fallot
Investigations - What do you see on scan?
Treatment
Investigations
- Chest x-ray –> Boot shaped heart
- ECG –> Right ventricular hypertrophy (RBBB)

Investigations
Treatment
Investigations

Tx
- Give ibuprofen/indomethacin to infant to promote duct closure (inhibits prostaglandin synthesis) - about a week after baby is born if defect still present
Definitive - transcatheter PDA closure (if severe)
2 causes of cyanotic congenital heart disease and treatment
(Common in the first 24 hours of life and may occur when the child is crying or unwell)
(Nitrogen washout test - infant given 100% oxygen for 10 minutes - pO2 <15kPa on an ABG indicates cyanotic congenital heart disease)
- Tetralogy of fallot
- Transposition of the great arteries
Tx
- Prostaglandin E1 e.g alprostadil –> keeps the ductus arteriosus patent

Tx
Enuresis alarm –> have sensor pads that sense wetness
Desmopressin –> If alarm doesn’t work/short-term control needed
Give advice
- Encourage to empty bladder regularly in the day and before sleep
Reward system
- Star charts –> Praising the child for a dry night
