On Examination
• Is the diagnosis Medical or Surgical?• Sepsis?• Cardiac? Would you commence any treatment?• Anything else?
• What other investigations would you like?
What next?
• Cardiology called and requested urgent review• Advised not to start PGE• Echo : Normal cardiac structures and function, small PFO L>R shunt (no cardiology
follow up required)
Cardiology Consult
Blood work up
Methemoglobinemia: Blood disorder where there is an abnormal amount of MetHb formation, thus unable unable to release oxygen effectively to body tissues. MetHb = Ferrous Iron of Hemehas been oxidised to ferric state.
• VBG show Met Hb 46.5%• Normal CBC and electrolytes• No FH of blood diseases• Baby had normal O2 saturations pre-circumcision• Diagnosis Medical : Iatrogenic Methemaglobinemia from Topical
Lidocaine• Treated with Low dose Methylene Blue• Recovered and went home the following day

rule out surgical abdomen
What would you do?
• Diagnosis Medical or Surgical?• Admit for Observation or Transfer?
Progress
• 2nd bolus continued en route• Required further fluid resuscitation at tertiary centre but not immediately• Surgery that evening, perforated appendix.• Ventilated on PICU post-op but no inotropic support• Full recovery

A – Required airway support but gagging on GuedelB – Resp rate 10, sats 100% on hi-flow
- Good air entry bilaterallyC – Initial bradycardia down to 60 improved with oxygen and airway support
- Good volume peripheral pulses- BP 100 / 70
D – GCS – 8/15 - E2, V2, M4- Pupils 4mm, sluggishly reactive- hypotonic
E – Apyrexial, no rash, no signs of trauma.
Diagnosis
•Medical or Surgical?•What would you do next?
Progress
• Anesthesia contacted
• RSI
• Morphine & Midazolam sedation
• IV ceftriaxone
• Urgent CT Head requested
• Diagnosis Surgical
• Posterior Fossa Tumour
Further Management
• Emergency Shunt Decompression Performed• Subsequent surgical resection of cerebellar astrocytoma• Underwent protein beam therapy in US• Still recovering but started walking
• Not all vomiting is GI related• Beware vomiting in the absence of
diarrhoea• Constipation is a symptom not a
diagnosis• D+V is not always gastroenteritis• Nitrite +ve urine is not always UTI• Children can look well and smile with
appendicitis• Babies can look well with intussuception
• If you are not certain of the diagnosis and you are concerned do not discharge but observe
• Do not forget safeguarding• VBG is a valuable investigation• Head circumference is a valuable
investigation (not for ED but useful to plot in the community)
• GERD is common in the 1st 6 months but tends to settle once child able to sit and ingest solids
