Adolescents
- Remember to consider the points above, but be yourself, and allow the adolescent to be themselves.
- Be honest and authentic
- Inform parents it is a routine for us to give adolescents an opportunity to share their health experience confidentially (including psychosocial or “HEADSS” screening) –this should not be routine for medical students unless it is explicitly facilitated by a clinical workplace supervisor.
- Give plenty of time for responses when interviewing adolescents.

CAHS Guideline - Nutrition: Volume and Nutritional Requirements
- At what rate are fluids usually commenced for term and preterm infants? How are they increased?
- What fluid rate should infants with significant hypoxic ischaemic encephalopathy be on?
- Fluids are usually started at 60ml/kg/day for term infants and 80 mL/kg/day for preterm infants on day 1.
- Increments are progressively increased at 20 mL/kg/day (assuming no abnormal weight loss or gain or need for fluid restriction or fluid increase).
- Fluids are increased to a target of 150-170 mL/kg/day.
- Infants with significant hypoxic ischaemic encephalopathy may require fluid restriction 40-50ml/kg/day but need to ensure appropriate glucose delivery to achieve PGL>3.5.
CAHS Guideline - Nutrition: Volume and Nutritional Requirements
- When may you need to consider insensible losses and increase fluid requirements in infants?
Phototherapy/Radiant Warmers
Infants under phototherapy lights or on radiant warmers are prone to increased insensible water loss. In the omnibed incubator with newer technology, insensible water losses are not as significant as in other older incubators. An extra 10-20 mL/kg/day may be added to their daily fluid requirements if required.
CAHS Guideline - Nutrition: Volume and Nutritional Requirements
- How are fluids for infants calculated?
- Give a worked example.
Management
- Fluids are calculated on the infant’s birth weight until the birth weight has been reached. At certain times a predicted weight may be used instead of the current weight e.g. Oedema, PDA, failure to thrive.
- Fluid requirements are re-calculated each shift to ensure the volume being given is the same as the volume ordered.
- The weight is multiplied by the mL/kg/day in order to give the volume required for the 24 hour period.
- The total fluid requirement for the day is then divided by the number of feeds per day, or if on intravenous therapy it is divided by 24 to give the hourly rate of the infusion.
CAHS Guideline - Breastfeeding
- List 7 Health Benefits of Breastfeeding for the Infant & 3 Health Benefits for the Mother?
Principles
- Breast milk is specifically designed for human infants with both the mother and infant gaining physically and emotionally from the breastfeeding experience.
- Breast milk has the correct biochemical constituents necessary for optimal growth and development and assists in the prevention of respiratory and intestinal infections and the onset of allergies.
- Premature and some surgical infants may require individually tailored fortification of human milk to reach recommended intakes and acceptable
growth rates.
CAHS Guideline - Breastfeeding
- What should be done for mothers planning to breastfeed who are separated from their infants?
- When should the first expression occur?
- Why do introductory suck feeds need to be breast feeds?
- What are 5 Signs of readiness to suck?
- Any mother planning to breastfeed who is separated from her infant needs to start expressing to establish lactation.
- The first expression should be in the first hour after delivery of her infant and then around every 3-4 hours, culminating in 7–8 times each day including at least once overnight
- Introductory suck feeds are to be breast feeds; early breastfeeding is less
physiologically stressful than is early bottle feeding. The infant has a greater ability to control the flow of milk during breastfeeding and has more stable patterns of oxygenation.
CAHS Guideline - Breastfeeding
- Define Positioning and Attachment.
CAHS Guideline - Breastfeeding
- 4 Recommended Breastfeeding Positions for the Mother?
- 4 Recommended Breastfeeding Positions for the Infant?
CAHS Guideline - Breastfeeding
- 8 Signs of Correct Positioning and Attachment?
- 4 Signs of Poor Attachment?
Signs of Correct Positioning and Attachment
1. Lips widely flanged and sealed around the breast.
2. Infant’s chest in close contact with mother’s chest.
3. Head is slightly extended, with the chin pressed into the breast.
4. The nose is free without the mother holding back her breast.
5. Absence of clicking sounds.
6. Absence of dimpling in infants cheeks.
7. Movement of whole jaw with muscular movement visible around ears.
8. Once infant is attached and sucking effectively there is no nipple pain or
trauma.
CAHS Guideline - Breastfeeding
- 9 Questions to Ask the mother about Breastfeeding prior to discharge?
Infant Feeding Guidelines
- What are the 3 recommendations regarding breastfeeding?
Recommendations
1. Encourage, support and promote exclusive breastfeeding to around 6 months of age.
2. Continue breastfeeding while introducing appropriate solid
foods until 12 months of age and beyond, for as long as the mother and child desire.
3. While breastfeeding is recommended for the first 6 to 12 months and beyond, any breastfeeding is beneficial
to the infant and mother.
Infant Feeding Guidelines
- What are the 5 recommendations for individuals to promote a supportive social and physical environment for breastfeeding?
Recommendations for Individuals
1. Provide antenatal information and counselling about the benefits and practical aspects of breastfeeding (and the risks of not breastfeeding) to all potential mothers, fathers and primary carers.
2. Pay particular attention to positioning and attachment when advising on breastfeeding.
3. Take steps to identify breastfeeding difficulties by asking appropriate questions during any health-related visits with the mother. Manage those difficulties if appropriately qualified, or refer to a health professional for management (e.g. lactation consultant).
4. Provide postnatal breastfeeding support information.
5. A pacifier (dummy) may be offered, while placing infant in back-to-sleep-position, no earlier than 4 weeks of age and after breastfeeding has been established.
Infant Feeding Guidelines
- What are the 4 recommendations for creating a supportive environment for breastfeeding mothers?
Infant Feeding Guidelines
- Are there any situations where breastfeeding is contraindicated?
- There are very few contra-indications for breastfeeding. Maternal and paternal smoking is negatively associated with breastfeeding duration and predominant or exclusive breastfeeding, but smoking and environmental contaminants are not valid reasons to stop breastfeeding.
- In households where smoking occurs, infants who are breastfed have lower rates of respiratory infection.
- Consumption of moderate amounts of alcohol by breastfeeding women may be associated with increased risk of adverse infant outcomes, but moderate, infrequent use of alcohol is not an indicator for stopping breastfeeding.
- Most prescription and over-the-counter drugs, and most maternal illnesses are not indications for discontinuing breastfeeding
Infant Feeding Guidelines
- What are 12 recommendations when an infant is not receiving breastmilk?
When an infant is not receiving breastmilk
If an infant is not breastfed or is partially breastfed, commercial infant formulas should be used as an alternative to breastmilk until 12 months of age. It is important to prepare and store feeds correctly.
Infant Feeding Guidelines
- What are 6 recommendations regarding other fluids aside from milk in infant feeding?
Other fluids in infant feeding
For infants over the age of 6 months or for those who are not exclusively breastfed, tap water is preferred (as consistent with the Australian Dietary
Guidelines) but this should be boiled and cooled for infants until 12 months
of age. Consumption of fruit juice may interfere with the intake of nutrient dense foods and fluids and increase the risk of damaging emerging teeth.
Tea, herbal teas, coffee and other beverages are of no known benefit to an infant and could possibly be harmful.
Infant Feeding Guidelines
- What are the 8 recommendations regarding transition to solid foods ?
The transition to solid foods
At around the age of 6 months, infants are physiologically and developmentally
ready for new foods, textures and modes of feeding, and they need more
nutrients than can be provided by breastmilk or formula alone. By 12 months of age, a variety of nutritious foods from the Five Food Groups, as described in the Australian Guide to Healthy Eating, is recommended.
Infant Feeding Guidelines
- What are the 7 recommendations regarding feeding after 12 months?
After 12 months
Solid foods should provide an increasing proportion of the energy intake after 12 months of age. Offering a variety of nutritious foods is likely to help meet the need for most nutrients and provide a basis for healthy eating habits.
Infant Feeding Guidelines
- What are the 6 recommendations regarding Caring for infants’ food?
Caring for infants’ food
All foods given to infants should be nutritious and be fed in a safe way. Foods provided to an infant must be free of pathogens and of suitable quantity, size and texture. Infants should be supervised during feeding. Propping the bottle against the infant’s mouth and leaving the infant to feed from the bottle without supervision should be avoided as the infant may fall asleep with the bottle’s teat still attached to their mouth, increasing the risk of choking, ear infection and dental caries.
Infant Feeding Guidelines
- What are the 2 recommendations regarding Food allergies?
Food allergies
Breastfeeding may be associated with a reduced risk of atopic disease in
infants with and without a family history of atopy. Introducing a variety of
solid foods around the age of 6 months is consistent with reducing the risk
of developing allergic syndromes. There is no evidence that delaying the
introduction of solid foods beyond this age reduces the risk of atopic disease.
Delay in the introduction of solid foods until after the age of 6 months is
associated with increased risk of developing allergic syndromes.
Treatment of proven food allergies involves avoiding foods known to
cause symptoms
Infant Feeding Guidelines
- What is the recommendation regarding Colic?
- 2 recommendations regarding constipation?
Colic
- Changes in diets and restrictions on individual foods have had limited success in the treatment of colic.
- Research into this common area of concern is ongoing, but at this point no specific dietary recommendations for the treatment of colic can be made.
- Ensure that any dietary modification or pharmacological intervention is safe and does not result in nutritional deficiencies.
Infant Feeding Guidelines
- What are the 3 recommendations regarding dietary fats?
- 2 recommendations regarding diarrhoeal disease?
Dietary fat
- Dietary fat is an important source of energy. Some fats provide essential fatty acids. Fat is also needed for the absorption of essential fat-soluble vitamins.
- Restriction of dietary fat is not recommended during the first two years of life because it may compromise the intake of energy and essential fatty acids and adversely affect growth, development, and the myelination of the central nervous system.
- Consumption of nutrient-poor discretionary foods with high levels of saturated fat (e.g. cakes, biscuits and potato chips) should be avoided.

Standard Fluids
- Standard intravenous fluids are those that are commercially pre-made and available at Perth Children’s Hospital. Standard (pre-mixed) intravenous fluids supplied by an external manufacturer are always preferred wherever possible.
- Standard intravenous fluids kept at PCH that are supplied from Baxter via Health Support Services (HSS) are described below in Table 1.
- High risk fluids, i.e. those containing potassium or those that are significantly hyper or hypo-osmolar are to be stocked within automated dispensing machines (ADMs) and not left in clinical areas. High risk fluids that are supplied from Baxter via pharmacy are described in Table 2.
CAHS Guideline: Feed Intolerance
- Risk of Feed intolerance?
- Background?
- Signs of Feed intolerance?
Risk: Feed intolerance can be indication of underlying or developing gastric problems. Delayed identification and management may lead to adverse outcomes.
Background: The decision whether the feeds should be continued, reduced, or stopped will be at the discretion of the attending neonatologist. Feeds are usually stopped if there are bile-stained or large gastric residuals and vomiting and/or abdominal distension and/or
blood in the stools. Investigations are carried out and an assessment is made after 12 to 24 hours. Feeds can generally be restarted when the infant has stabilised and has had a 12-24 hour absence of any significant clinical signs of feed intolerance.
CAHS Guideline: Feed Intolerance
- What is Bilious Vomiting? What can it be a sign of? Management?
- What are Bilious Aspirates? What can they be a sign of? Management for Infants <32 and >32 weeks?
CAHS Guideline: Feed Intolerance
- What can vomiting be a sign of with feed intolerance?
- What can Abdominal Distension be a sign of with feed intolerance?
Vomiting
Vomiting (without bile) may be the result of an over distended stomach, poorly positioned feeding tube, Gastro Oesophageal Reflux, overstimulation in a LBW infant or may be more sinister - infection, obstruction or a metabolic or neurological disorder.
Lecture: Paediatric Hydration
- 3 Basic Principles?
- Mild, Moderate, Severe Dehydration?
Basic Principles
1. ASSESS the level of dehydration
2. PLAN & implement your hydration intervention
3. REASSESS hydration according to level of severity
Assess the Level of Hydration
- Mild <3% of body weight lost
- Moderate ~5% of body weight lost
- Severe >7% of body weight lost
Lecture: Paediatric Hydration
- What clinical signs are associated with each of the levels of dehydration?
Lecture: Paediatric Hydration
- What level of dehydration does this child have?
= Mild, still able to produce tears and chlid is upset (no neurological demise)
Lecture: Paediatric Hydration
- What level of dehydration does this child have?
= Severe - look at skin turgor! But the child is still upset (not shocked/ neuro)
Lecture: Paediatric Hydration
- What are the 2 components of hydration intervention?
- What is the 4,2,1 rule of fluid maintenance in children? Give examples?
Plan a hydration intervention: MAINTAINENCE (4,2,1 rule)
+ REPLACEMENT
Lecture: Paediatric Hydration
- What are the principles of Fluid Replacement? (VoldeMorte Adjustments)
REPLACEMENT
* Replace a VOLUME determined according to the percentage of dehydration.
* The MODE and RATE of rehydration vary according to clinical scenario.
= B. NGT ORS - 700mL in 4hrs
- Moderate dehydration
- 50mls/kg = 700mls
- OR IV but if confident gastro then NGT is fine, would always opt for oral if possible as body can better self-regulate electrolytes
- Ceiling for IV fluid rates for maintenance = 100ml/hr
- ORS – oral rehydration solution
- Can often be better to learn rehydration based on the diagnosis
= B. 421 rule = 8kg = 4x8=32 and 2/3rds maintenance for bronchiolitis = 21ml
= NG ORS 21mL/hr
= C. IV 0.9% NaCl 460mL bolus
- Resus situation so normal saline is most likely option but 5% glucose solution also not a big deal at a 20ml/kg bolus = 23x20 = 460mL
= C. 0.9% NaCl at 88ml/hr post bolus
- Risk of cerebral oedema from too rapid a correction in hydration state (becuase there has usually been a period of cerebral compensation)
- Strategy: SLOW replacement of 5% + maintainence
- Volume: Maintainence + 5% (replaced over 48hrs) minus bolus provided initially (if bolusing, give 10ml/kg)
- Mode: IV
- Rate: Slow
- REview regularly (often in ICU)

Management strategies for Faltering Growth?
Food Protein-Induced Allergic Proctocolitis (FPIAP)
- What is it?
- How is it diagnosed?
Food protein-induced allergic proctocolitis (FPIAP) is a type of delayed inflammatory non-IgE mediated gut food allergy. Symptoms usually start at one to four weeks of age and range from having blood, which is sometimes seen with mucous in bowel movements, to blood stained loose stools or diarrhoea. Infants with FPIAP are usually otherwise healthy and growing well. FPIAP mostly occurs in breastfed infants, but can also occur once cow’s milk or soy based formula is commenced. The main triggers are cow’s milk or soy.
Food Protein-Induced Allergic Proctocolitis (FPIAP)
- Management if a child is breastfeeding?
- Management if an infant is formula fed?
- How often does it resolve?
Resolution of FPIAP
- Resolution of FPIAP usually occurs in 50% of infants by the age of six months, and 95% of infants by the age of nine months.
- It is generally recommended to reintroduce the offending food/s to the mother’s or infant’s diet after it has been eliminated for six months or at 12 months of age.
- For infants who have more severe symptoms, such as blood stained diarrhoea, the offending food/s may be gradually introduced under the supervision of a dietitian.

- When is Referral to the a specialist weight management clinic is required for an overweight/obese child?
RCH Guideline - Dehydration
- What is the best measure of dehydration?
- What is the best measure of fluid rehydration?
- What history will you take?
- Weight loss is the best measure of dehydration. Clinicals signs can help estimate the severity of dehydration but are often imprecise.
- The most accurate assessment of degree of dehydration is based on the difference between the pre-morbid body weight (within last 2 weeks) and current body weight (eg a 10 kg child who now weighs 9.5 kg has a 500 mL water deficit and is 5% dehydrated).
- If a child is haemodynamically unstable (ie in shock), prompt fluid resuscitation with fluid boluses must be given. Sepsis must be considered.
- Rehydrate enterally (orally or via nasogastric route), unless severe dehydration or shock.
- When a recent weight is not available, use the history and clinical examination to estimate the degree of dehydration.
RCH Guideline - Dehydration
- 6 Risk factors for severe dehydration and electrolyte disturbances?

Consider consultation with local paediatric team when
1. Child presents with shock
2. Child has electrolyte disturbance and/or predisposing factors for severe or complicated dehydration
Consider transfer when
1. Clinical signs of shock persist after maximum of 40 mL/kg fluid given in boluses. Consider other possible causes of shock (eg sepsis and need for antibiotics) other than dehydration alone.
2. Severe electrolyte derangement
