This is a critically unwell child requiring simultaneous resuscitation and assessment to identify the underlying cause with appropriate interventions.
1. List the acid base abnormalities
Severe mixed acidosis
High anion gap metabolic acidosis (HAGMA) – anion gap = 22, HCO3 = 11, with very high lactate level
Respiratory acidosis, expected CO2 = 24, actual = 37 (within limitations of VBG) with significant hypoventilation
Severe hypoglycaemia, requiring glucose iv
Depletion of total body Potassium (in view of acidosis, actual Potassium closer to 2)
2. DDx
Sepsis
Toxins – sulphonylureas, metformin, (snake bite, scorpion sting)
Seizures
Hypoperfusion/ shock
trauma – head injury, other
3. Normal Vital signs for a two year old:
BP = 80/40 – 100/70
PR = 100 – 150/min
T = 36.5 – 37.5
RR = 25-40
This child is hypotensive, tachycardic and hypoventilating
4. Time critical emergency.
Resuscitation Bay
Team Approach
Assume team leadership and allocate roles
Clear closed loop communication
Ensure rest of department handed over to senior colleague
Continue Oxygen as given
No immediate airway compromise, however prepare for RSI in event of deterioration or inadequate response to initial therapy. ivi access, 3 attempts, then Intra Osseus in proximal Tibia.
Glucose – bolus of 3 ml/kg of 10% Dextrose, repeated X 3
Fluids – bolus of 10 ml/kg of 0.9% Saline, repeated X 3
Seizure control – 0.1 ml/kg midazolam, repeat X 3
Antibiotics – 50 ml/kg Ceftriaxone as indicated
Allocate senior staff member to be with grand parents (explain events), attempt to contact parents
