So if a baby weights 5kg, what is the normal requirement of feed for them?

How are maintenance fluids calculated in children?

1st 10kg = 100mls/kg/day
2nd 10kg = 50mls/kg/day
3rd and subsequent kg = 20mls/kg/day

Freddie is 28kg and is vomiting, requiring maintenance IV fluids, calculate his hourly IV fluid requirement?

10kg - 100mls/kg/day = 1000 / day
10kg - 50mls/kg/day = 500 / day
8kg - 20mls/kg/day = 160 / day

1000 + 500 + 160 = 1660/24 to get hourly = = 70mls per hour

At what age is the median for walking steadily?

15 months

What may be a reason an 18 month old isn’t walking, and it is not a cause for concern?

They may be a bottom shuffler - find they get around a lot faster doing this, so less inclined to walk

How would you test an 18 month old who isn’t walking to see if there are more worrying signs?

Lie them supine and see if they roll over to prone and get themselves off the floor

What is important when looking for developmental warning signs? - what can you do to test/find out more?

1. Family history 2. Maternal concern 3. Persisting primitive reflexes 4. Discordant development (one area slower in development than others) 5. Regression (very concerning)

What is the moro reflex?

Holding baby carefully, move baby downwards (as if pretending to fall) and see if they splay both arms outwards - looking forward asymmetry in this action

What other primitive reflexes can be tested in a baby?

Palmar reflex - finger in their palm, they will hold your finger Finger in mouth - suck finger

At what age do primitive reflexes disappear?

3 months

Which primitive reflex develops from 9 months and stays for life?

Parachute reflex - put hands forward to stop falling on face

What screening procedures are done in a baby - eyes?

Looking for red reflex: loss of this can mean... Retinoblastoma Cataracts

What is the 1 week Guthrie screening procedure for? (5)

1. PKU 2. Hypothyroidism 3. CF 4. Haemoglobinopathies 5. Acylcarnitine

What is enuresis?

Inappropriate voiding of urine after the age at which bladder control should have been achieved

What is encopresis?

Passage of fences into the clothes by day or night (after the age of 4 years is abnormal)

What are the causes of encopresis after the age of 4?

Chronic constipation/faecal impaction

What is concerning about a 2 year old with a history of asthma has a RR of 12 and a heart rate of 80?

They should have a RR and HR higher than those given - sign they may be suffering from hypoxia, and exhaustion

What % of babies will have passed meconium within 48 hours?

95%

What are the possible causes of delayed passage of meconium?

1. Hirschsprungs 2. Anal atresia/stenosis 3. Meconium ileus 4. Volvulus

What % of babies will micturate within 24 hours?

95%

What % of birthweight loss is worrying?

10% or more

What % of babies should sleep through the night by 6 months?

90%

How many hours sleep do babies at birth require?

16 hours per day

How many hours sleep do babies at 6 months old require?

14 hours per day

At what age range does 'sudden unexplained death' occur in children?

1-12 months

What is the difference in cardiac arrest in children compared to adults?

Childrens cardiac arrest is not often of cardiac origin - more commonly respiratory, whereas with adults it is normally cardiac

What are the respiratory failures that can lead to cardiac arrest? (6)

``` Obstructive causes: 1. Foreign body 2. Asthma 3. Croup Respiratory depression causes: 1. Convulsions 2. Poisoning 3. Raised ICP ```

What are the circulatory failures that can lead to cardiac arrest? (6)

``` Fluid maldistribution: 1. Septic shock 2. Anaphylaxis 3. Cardiac failure Fluid loss: 1. Vomiting 2. Burns 3. Blood loss ```

How do you open a children's airway?

0-8 years - ensure head is just looking straight up (if lying supine for example) 8+ years - hyperextend head, but not as much as in adults 'sniffing the morning air'

What signs in children are there of respiratory distress? (6)

1. Subcostal/intercostal recession 2. Tracheal tug 3. Grunting 4. Nasal flare 5. Head bobbing 6. Exhaustion - increased effort may be absent!

How do you test for breathing efficacy? (4)

1. Chest expansion 2. Auscultation - air entry ok? 3. Pulse oximetry (>94%) 4. Blood gas - high CO2?

What is the response to breathing if there is a problem? (6)

1. If not breathing - ventilate with a bag-valve mask device 2. Give 02 15l/min via a non-rebreathe mask with reservoir bag 3. Aim 02 saturations 94-98% 4. ABG 5. CXR 6. Site an NG tube (especially if used a BVM)

What is the response in circulation for emergency response in children? (4)

1. IV/IO acccess 2. Blood gas, glucose stick, laboratory tests (FBC, U&Es, LFTs, CRP, blood culture, cross-match) 3. 3-lead cardiac monitoring or 12-lead ECG 4. Fluid bolus 20mls/kg

Why is hypotension in a child worrying?

It is a pre-terminal sign! Childrens blood pressures do not drop until the very last minute

In the disability category for RRAPID for children, what is important to recognise? (5)

1. AVPU - patient alertness 2. Pupils - size and reaction to light 3. Posture 4. Blood glucose 5. Evidence of seizure?

What is important to assess in exposure in RRAPID? (4)

1. Rashes 2. Temperature 3. Injuries (fractures/bruising/burns) 4. Smells (ketones/poisons)
