Q

What examination should you do for a child with BRUE?

A

General: Vital signs, BM, Growth (weight and head circumference), dysmorphic features, any bruises or marks suspicious of NAI

Respiratory including ENT: any signs of URTI or LRTI

CVS: femoral pulse for coarctation of aorta, any murmurs

Abdominal: Tenderness with a sausage shaped mass, groin for hernias

Q

What investigations are done for a high risk and low risk patient?

A

Low Risk

Q

After a hypo screen is taken, how is hypoglycaemia corrected in this emergency?

IMPORTANT CARD, LOOK AT IMAGE

A

Monitor BM hourly until stable, always take BM 10-15 minutes after intervention

If child is conscious and not vomiting

  • PO glucose dextrogel 1⁄2 tube (5g) for infants <6 months and 1 tube if >6 months
  • In an older child give oral glucose 10–20 g
  • Followed by snack of starchy carbohydrates or a milk feed in infants

Altered consciousness

  • 2 ml/kg 10% glucose/0.9% NaCl as IV bolus followed by infusion containing 10% glucose
  • If no IV access stat glucagon IM: 0.5mg for patients < 8 yrs age or <25 kg, 1 mg for patients > 8 yrs age or >25 kg. Followed by IV or IO infusion of glucose

Q

How do you calculate glucose infusion rate and what does this tell you?

A

Most children will be normoglycemia on 5-8 mg/kg/min

If <12 think hyperinsulinaemia so refer urgently to endocrinology

Q

How is malnutrition in children managed?

A
  • Eating foods high in energy and nutrients
