Paeds Flashcards
Difference in presentation between vasovagal syncope and anaphylaxis with collapse
Vasovagal - pale, bradycardic
Anaphylaxis - flushed, tachycardia
Presentation for simple febrile seizure
6-60 month child, previously well
generalised tonic-clonic, no focal component
<15 mins

Types of seizures
Partial:
From focal lesion, often temporal lobe
Simple partial (unimpaired consciousness)
- motor, somatosensory, autonomic, psychic signs
Complex partial (impaired consciousness, amnesia)
- +/- automatism
Complex partial proceeding to generalised
Generalised:
Absence - lapse of consciousness

6 puffs salbutamol via spacer
Discharge when can space to 2hours
Moderate:
Above plus:
May need full blast
Prednisolone 1mg/kg if >5 or meeting criteria

Severe:
Above plus:
Salbutamol 2.5-5mg nebs
Ipratropium 4 puffs or 250mcg nebs
Life threatening:
Urgent transfer
Nebs - continuous
High flow O2
IV lines
Hydrocortisone 4mg/kg IV
Symptoms of hypovolaemic shock in children
Early:
Pallor, cool peripheries, drowsiness/disinterest, tachycardia disproportionate to fever/distress, reduced urine output
Cap refill not reliable
Late:
Low BP
Management of shock in children
IV access - aim 24G + or intraosseous
IVF - 20mg/kg bolus
Consider trauma - C spine immobilisation, exsanguination - FFP and blood
Hypotension refractory to volume replacement - dopamine 5mcg/kg/min increase to 10-15
Consider spinal shock

Management of poisoning
Airway - intubate if airway corrosion, GCS <8, prolonged seizure

NaHCO3 if sodium channel blockade
Disability
Seizures - Midazolam 0.15mg/kg IV, repeat
