Paediatrics Flashcards
principles of neonatal resuscitation
- warm baby - drying, heat lamp, plastic bag still wet
- calc APGAR score at 1.5 and 10mins
- stim breathing - drying, check for obstruction
- inflation breaths - 2 cycles of 5 (3s each), air +O2 in prem, if no response then 30s ventilation breaths, still no response then chest compressions
- chest compressions - 3:1 with ventilation breaths if HR<60
- severe situations may need IV drugs and intubation
APGAR score
Vitamin K in newborn
- Vit K IM given
- all babies born with vit K deficiency (needed for blood clotting)

physiological jaundice
- fetal RBC break down quicker and less developed liver function
-normal rise in bilirubin from 2-7d after birth - resolves by day 10 - jaundice in first 24h or lasting >14d (term), >21d (prem) is pathological
causes of neonatal jaundice
- increased production of bilirubin (HDOTN, haemorrhages, polycythaemia, sepsis, G6PD deficiency)
- decreased clearance of bilirubin (prem, breast milk jaundice, neonatal cholestasis, extrahepatic biliary atresia, endocrine disorders)
jaundice in premature neonates
- physiological jaundice exaggerated so higher risk of complications (kernicterus)
- need treatment
breast milk jaundice
- breast milk contains components that inhibit livers processing of bilirubin, also at higher risk of dehydration and inadequate feeding slows down bowels causing more bilirubin to be reabsorbed
investigations for neonatal jaundice
- FBC, bilirubin (conjugated/unconjugated), blood type testing, TFT
- Direct Coombs test for haemolysis
- blood and urine cultures
- G6PD levels
management of neonatal jaundice

- anorexia, lethargy, polydipsia/uria, FTF, bony deformities (renal osteodystrophy), htn, proteinuria
- management - nutrition (NG/PEG), phosphate restriction, vit D, salt supplements, erythropoietin (prevent anaemia), GH, dialysis, transplant
nephrotic syndrome
- basement mem becomes permeable to protein
- triad of low albumin, oedema and high proteinuria
- 90% caused by minimal change disease (no clear pathology)

- Mx - high dose prednisolone for 4w then weaned slowly, low salt diet, diuretics, albumin infusions, abx prophylaxis
minimal change disease
- nephrotic syndrome
- no clear reason why
- renal biopsy and microscopy don’t detect abnormality
- urinalysis - protein and hyaline casts
- Mx - prednisolone - most make full recovery
nephritic syndrome
- nephron inflammation causing decreased renal function, haematuria, proteinuria (less than nephrotic s)
- most common causes in children: post-streptococcal glomerulonephritis and IgA nephropathy (Berger’s disease).
- can also be caused by SLE and Alport syndrome
Post-streptococcal glomerulonephritis
- 1-3w after beta haemolytic strep infection (eg tonsilitis)
- immune complexes get stuck in glomeruli causing inflammation and AKI
- supportive Mx - 80% full recovery
- if worsening then Tx with antihypertensives and diuretics
IgA nephropathy (Berger’s disease)
- causes nephritic syndrome
- Related to Henoch Schoenlein purpura (IgA vasculitis)- purple purpuric rash in lower legs and buttocks from blood vessels leaking, arthritis, GI problems, condition usually improves on its own
- IgA deposits in the nephrons and glomerular mesangial proliferation on biopsy
- teenagers
- supportive Tx and immunosuppression (steroids and cyclophosphamide)
SLE
- mostly female teenagers
- inflammatory autoimmune connective tissue disease
- multiple anti-nuclear autoantibodies against double stranded DNA
- haematuria and proteinuria indicate biopsy
- malar rash (butterfly over cheeks/nose)
- immunosuppression needed
Alport syndrome
- genetic condition with kidney disease, sensorineural hearing loss and eye abnormalities
- progression could be slowed by ACEi, avoid NSAIDs, healthy lifestyle, may eventually need dialysis or transplant
hypospadias
- males, urethral meatus is displaced to the ventral side of penis, most just to bottom of glans but can be anywhere on penis
- epispadias if on top side
phimosis
- Inability to retract foreskin over glans penis
- Physiologic – normal in children and resolves around age 5-7
- Pathological – occurs due to scarring, infection or inflammation – may need surgery
renal agenesis
- no kidneys
- severe oligohydramnios = Potter sequence (pulmonary aplasia causing resp failure, fetal compression, FATAL)
Multicystic dysplastic kidney
- result of failure of union of ureteric bud and nephrogenic mesenchyme
- non-functioning with large fluid filled cysts - no renal tissue or connection to bladder
- only survive if unilateral
cystic dysplastic kidneys
- Caused by autosomal recessive polycystic kidney disease (ARPKD), or dominant (ADPKD), renal cysts or diabetes
- some normal renal tissue but both always affected
- ADPKD = childhood htn and CKD - associated with liver/pancreas cysts, cerebral aneurysms and mitral valve prolapse
Duplex kidney
Vary from simply a bifid renal pelvis to complete division of the two ureters. May have abnormal drainage and can lead to reflux in the lower one. One may drain into vagina or urethra directly.
Vesico-ureteric reflux
- reflux of urine up dilated ureters
- predisposes to infection and renal scarring (reflux nephropathy)
- diagnose by MCUG
- Mx - avoid constipation, avoid excessively full bladder, prophylactic abx, surgery
haemolytic uraemic syndrome

calculating maintenance fluid
- Children >28d – Holliday-Segar formula
o 100 ml/kg/day for the first 10kg of weight
o 50 ml/kg/day for the next 10kg of weight
o 20 ml/kg/day for weight over 20kg
calculating fluid replacement
- Calculate % dehydration – signs of dehydration but no red flags (5%), red flags (10%)
- Fluid deficit (mL) = % dehydration x weight (kg) x 10
- Total fluid requirement (mL) = maintenance fluids (mL) + fluid deficit (mL)
