    FOREWORD BY THE DIRECTOR GENERAL OF HEALTH

    Malaysia like the rest of the world has 3 more years to achieve the Millennium Developmental Goals (MDG). MDG 4 is concerned with under 5 mortality. Although we have done very well since lndependence to reduce our infant and toddler mortality rates, we are now faced with some last lap issues in achieving this goal.

    Despite urbanization there are still many children in the rural areas. This constitutes a vulnerable group in many ways. Among the factors contributing to this vulner-ability is the distance from specialist care.

    There is a need to ensure that doctors in the frontline are well equipped to handle common paediatric emergencies so that proper care can be instituted from the very beginning.

    Although all doctors are now required to do 4 months of pre-registration training in Paediatrics, this is insufficient to prepare them for all the conditions they are likely to meet as Medical Officers in district hospitals and health clinics. Hence the effort made by the paediatricians to prepare a protocol book covering all the common paediatric problems is laudable. I would also like to congratulate them forbringing out a third edition within 4 years of the previous edition.

    l am confident that this third edition will contribute to improving the care of children attending the Ministry’s facilities throughout the country.

    Dato’Sri Dr Hasan Bin Abdul RahmanDirector General of Health, Malavsia

    FOREWORD TO THE THIRD EDITION

    It has been 7 years since we produced the first edition of a national protocol book for Paediatrics. This effort was of course inspired by the Sarawak Paediatric Protocols initiated by Dr Tan Poh Tin. The 2nd edition in 2008 has proven to be very popular and we have had to recruit the services of the Malaysian Paediatric Association (MPA) to produce extra copies for sale. It is now the standard reference for House officers in Paediatrics.

    In producing a third edition we have retained the size and style of the current ver-sion, essentially only updating the contents. Again it is targeted at young doctors in the service many of whom seem to have had a suboptimal exposure to paediatrics in their undergraduate years. It is hoped that the protocol book will help them fill in the gaps as they prepare to serve in district hospitals and health clinics.

    The Ministry of Health has once again agreed to sponsor the printing of 1000 books and 500 CDs for distribution to MOH facilities. We shall be soliciting the help of the MPA in producing extra books to be sold to those who wish to have a personal copy. As a result of the full PDF version being available on the MPA website, we have had requests from as far away as Kenya and Egypt to download and print the material for local distribution. We have gladly allowed this in the hope that it will contribute to better care of ill children in those and other neigh-bouring countries.

    As previously this new edition is only possible because of the willingness of busy clinicians to chip in and update the content for purely altruistic reasons and we hope this spirit will persist in our fraternity. Prof Frank Shann has gracefully agreed for the latest edition of his drug dosages handbook to be incorporated into the new edition. The Director General of Health has also kindly provided a foreword to this edition.

    We wish to thank all who have made this new edition possible and hope this combined effort will help in improving the wellbeing of the children entrusted to our care.

    ANTHROPOMETRIC MEASUREMENTS

    Age Weight Height Head size

    birth 3.5 kg 50 cm 35 cm

    6 months 7 kg 68 cm 42 cm

    1 year 10 kg 75 cm 47 cm

    2 years 12 kg 85 cm 49 cm

    3 years 14 kg 95 cm 49.5 cm

    4 years 100 cm 50 cm

    5-12 years 5 cm/year 0.33 cm/year

    Points to NoteWeight • In the first 7 - 10 days of life, babies lose 10 - 15% of their birth weight. • In the first 3 months of life, the rate of weight gain is 25 gm/day • Babies regain their birth weight by the 2nd week, double this by 5 months age, and triple the birth weight by 1 year of age • Weight estimation for children (in Kg): Infants: (Age in months X 0.5) + 4 Children 1 – 10 years: (Age in yrs + 4) X 2

    Head circumference • Rate of growth in preterm infants is 1 cm/week, but reduces with age. Head growth follows that of term infants when chronological age reaches term • Head circumference increases by 12 cm in the 1st year of life (6 cm in first 3 months, then 3 cm in second 3 months, and 3 cm in last 6 months)

    Other normal values are found in the relevant chapters of the book. References:1. Advanced Paediatric Life Support: The Practical Approach Textbook, 5th Edition 20112. Nelson Textbook of Pediatrics, 18th Edition.

    ENERAL PAED

    IATRICS

    General Notes • Many vaccines (inactivated or live) can be given together simultaneously (does not impair antibody response or increase adverse effect). But they are to be given at different sites unless given in combined preparations. Vaccines are now packaged in combinations to avoid multiple injections to the child. • sites of administration - oral – rotavirus, live typhoid vaccines - intradermal (ID) - BCG. Left deltoid area (proximal to insertion deltoid muscle) - deep SC, IM injections. (ALL vaccines except the above) • anterolateral aspect of thigh – preferred site in children • upper arm – preferred site in adults • upper outer quadrant of buttock - associated with lower antibody level production

    Immunisation : General contraindications • Absolute contraindication for any vaccine: severe anaphylaxis reactions to previous dose of the vaccine or to a component of the vaccine. • Postponement during acute febrile illness: Minor infection without fever or systemic upset is NOT a contraindication. • A relative contraindication: avoid a vaccine within 2 weeks of elective surgery. • Live vaccine: Absolute contraindications - Immunosuppressed children -malignancy; irradiation, leukaemia, lymphoma, primary immunodeficiency syndromes (but NOT asymptomatic HIV). - On chemotherapy or < 6 months after last dose. - On High dose steroids, i.e. Prednisolone ≥ 2 mg/kg/day for > 7 days or low dose systemic > 2 weeks: delay vaccination for 3 months. - If topical or inhaled steroids OR low dose systemic < 2 weeks or EOD for > 2 weeks, can administer live vaccine. - If given another LIVE vaccine including BCG < 4 weeks ago. (Give live vaccines simultaneously. If unable to then give separately with a 4 week interval). - Within 3 months following IV Immunoglobulin (11 months if given high dose IV Immunoglobulins, e.g. in Kawasaki disease).

    3 weeks 3 months

    Live Vaccine HNIG Live vaccine (Human Normal Immunoglobulin)

    - Pregnancy (live vaccine - theoretical risk to foetus) UNLESS there is significant exposure to serious conditions like polio or yellow fever in which case the importance of vaccination outweighs the risk to the foetus. • Killed vaccines are generally safe. The only absolute contraindications are SEVERE local (induration involving > 2/3 of the limbs) or severe generalised reactions in the previous dose.

    The following are not contraindications to vaccination • Mild illness without fever e.g. mild diarrhoea, cough, runny nose. • Asthma, eczema, hay fever, impetigo, heat rash (avoid injection in affected area). • Treatment with antibiotics or locally acting steroids. • Child’s mother is pregnant. • Breastfed child (does not affect polio uptake). • Neonatal jaundice. • Underweight or malnourished. • Over the recommended age. • Past history of pertussis, measles or rubella (unless confirmed medically) • Non progressive, stable neurological conditions like cerebral palsy, Down syndrome, simple febrile convulsions, controlled epilepsy, mental retardation. • Family history of convulsions. • History of heart disease, acquired or congenital. • Prematurity (immunise according to schedule irrespective of gestational age)

    Vaccination: Special Circumstances • Measures to protect inpatients exposed to another inpatient with measles: - Protect all immunocompromised children with Immunoglobulin (HNIG) 0.25-0.5 mls/kg. (Measles may be fatal in children in remission from leukaemia) - Check status of measles immunisation in the other children. Give measles monocomponent vaccine to unimmunised children within 24 hrs of exposure. Vaccination within 72 hours aborts clinical measles in 75% of contacts - Discharge the inpatient child with uncomplicated measles. - Do not forget to notify the Health Office. • Immunisation in children with HIV (Please refer to Paediatric HIV section) • In patients with past history or family history of febrile seizures, neurological or developmental abnormalities that would predispose to febrile seizures:- - Febrile seizures may occur 5 – 10 days after measles (or MMR) vaccination or within the first 72 hours following pertussis immunisation. - Give Paracetamol (120 mg or ¼ tablet) prophylaxis after immunisation (esp. DPT) 4-6 hourly for 48 hours regardless of whether the child is febrile. This reduces the incidence of high fever, fretfulness, crying, anorexia and local inflammation. • Maternal Chicken Pox during perinatal period. (Please refer to Perinatally acquired varicella section) • Close contacts of immunodeficient children and adults must be immunized, particularly against measles and polio (use IPV).• In contacts of a patient with invasive Haemophilus influenzae B disease: - Immunise all household, nursery or kindergarden contacts < 4 years of age. - Household contacts should receive Rifampicin prophylaxis at 20 mg/kg once daily (Maximum 600 mg) for 4 days (except pregnant women - give one IM dose of ceftriaxone ) - Index case should be immunised irrespective of age.

    • Children with Asplenia (Elective or emergency splenectomy; asplenic syndromes; sickle cell anaemia) are susceptible to encapsulated bacteria and malaria. - Pneumococcal, Meningococcal A, C, Y & W-135, Haemophilus influenza b vaccines should be given. - For elective splenectomy (and also chemotherapy or radiotherapy): give the vaccines preferably 2 or more weeks before the procedure. However, they can be given even after the procedure. - Penicillin prophylaxis should continue ideally for life. If not until 16 years old for children or 5 years post splenectomy in adults. • Babies born to mothers who are HbeAg OR HbsAg positive should be given Hepatitis B immunoglobulin (200 IU) and vaccinated with the Hepatitis B vaccine within 12 hours and not later than 48 hours. Given in different syringes and at different sites. • Premature infants may be immunised at the same chronological age as term infants. (Please refer section on The premature infants for more discussion)

    Recommended Immunisation Schedule for Infants and Children Not Immunised at the Recommended Time

    Time of Immunisation Age at first visit

    Between 6 wks -12 mths 12 months and older

    1st visit BCG, DPT/DTaP, Hib1, IPV1, HBV1

    BCG, DPT/DTaP1, Hib1, IPV1, HBV1, measles (footnote 2) at 6 or 9 mths, MMR at 12 mths of age

    2nd visit (1 mth later) DPT/DTaP2, IPV2, HBV2, Hib2

    3rd visit (1 mth later) DPT/DTaP2,Hib2, IPV2, HBV2

    DPT/DTaP3, IPV3,

    4th visit (4 mths after 3rd visit)

    DPT/DTaP3,Hib3, IPV3, HBV3, DPT/DTaP4, IPV4,

    2-8 mths later HBV3, DTaP4, Hib4 & IPV4 (booster), measles in Sabah at 9 mths age, MMR at 12 mths age

    Polio, DT/DTaP, MMR (at school entry)

    Footnotes:1. For infants < 6 wks age, use “Recommended Immunisation Schedule for Infants & Children”. 2. Measles vaccine should be given only after 9 mths. (exception - given at 6 months in Sabah)3. For special groups of children with no regular contact with Health Services and with no immunisation records, BCG, HBV, DTaP- Hib-IPV and MMR can be given simultaneously at different sites at first contact.4. It is not necessary to restart a primary course of immunisation regardless of the period that has elapsed since the last dose was given. Only the subsequent course that has been missed need be given. (Example. An infant who has been given IPV1 and then 9 months later comes for follow-up, the IPV1 need not be repeated. Go on to IPV2.). Only exception is Hepatitis A vaccine.

    Well children with Normal hydrationVery few well children require intravenous fluids (IV). Whenever possible use an enteral (oral) route for fluids. These guidelines apply to children who are unable to tolerate enteral fluids.The safe use of IV fluid therapy in children requires accurate prescribing of fluids and careful monitoring because incorrectly prescribed or administered fluids are hazardous. If IV fluid therapy is required then maintenance fluid requirements should be calculated using the Holliday and Segar formula based on weight. However this should be only be used as a starting point and the individuals’ response to fluid therapy should be monitored closely by clinical observation, fluid balance, weight and a minimum daily electrolyte profile.

    Prescribing Intravenous fluidsFluids are given intravenously for the following reasons: • Circulatory support in resuscitating vascular collapse. • Replacement of previous fluid and electrolyte deficit. • Maintenance of daily fluid requirement. • Replacement of ongoing losses. • Severe dehydration with failed nasogastric tube fluid replacement (e.g. on-going profuse losses, diarrhoea or abdominal pain). • Certain co-morbidities, particularly GIT conditions (e.g. short gut or previous gut surgery)

    Resuscitation

    Fluids appropriate for bolus administration are:

    Crystalloids 0.9% Normal Saline

    Ringer’s Lactate @ Hartmann’s solution

    Colloids Gelafundin, Voluven

    4.5% albumin solution

    Blood products Whole blood, blood components

    • Fluid deficit sufficient cause impaired tissue oxygenation (i.e. clinical shock) should be corrected with a fluid bolus of 10-20mls/kg. • Always reassess circulation - give repeat boluses as necessary. • Look for the cause of circulatory collapse - blood loss, sepsis, etc. This helps decide on the appropriate alternative resuscitation fluid. • Fluid boluses of 10mls/kg in selected situations - e.g. diabetic ketoacidosis, intracranial pathology or trauma. • Avoid low sodium-containing (hypotonic) solutions for resuscitation as this may cause hyponatremia.• Check blood glucose: treat hypoglycemia with 2mls/kg of 10% Dextrose solution.

    Chapter 3: Paediatric Fluid and Electrolyte GuidelinesG

    ENERAL PAED

    IATRICS

  • 20

    • Measure Na, K and glucose at the outset and at least 24hourly from then on. More frequent testing is indicated in ill patients or those with co-morbidities. Rapid results of electrolytes can be done with blood gases measurements. • Consider septic work-up or surgical consult in severely unwell patients with abdominal symptoms (i.e. gastroenteritis).

    Maintenance • Maintenance fluid is the volume of daily fluid intake. It includes insensible losses (from breathing, perspiration, and in the stool), and allows for excretion of the daily production of excess solute load (urea, creatinine, electrolytes) in the urine. • Most children can safely be managed with solution of 0.45% saline with added glucose (i.e. 0.45% saline in 5% glucose or 0.45% saline in 10% glucose) depending on glucose requirement. • Sodium chloride 0.18 saline with glucose 5% should not be used as a maintenance fluid and is restricted to specialist area to replace ongoing loses of hypotonic fluids. These areas include high dependency, renal, liver and intensive care. • Most children will tolerate standard fluid requirements. However some acutely ill children with inappropriately increased anti-diuretic hormone secretion (SIADH) may benefit from their maintenance fluid requirement being restricted to two-thirds of the normal recommended volume. • Children who are at high risk of hyponatremia should be given isotonic solutions (i.e. 0.9% saline ± glucose) with careful monitoring to avoid iatrogenic hyponatremia in hospital.

    These include children with the following conditions: • Peri-or post-operative • Require replacement of ongoing losses • A plasma Na at lower normal range of normal (definitely if < 135mmol/L) • Intravascular volume depletion • Hypotension • Central nervous system (CNS) infection • Head injury • Bronchiolitis • Sepsis • Excessive gastric or diarrhoeal losses • Salt-wasting syndromes • Chronic conditions such as diabetes, cystic fibrosis and pituitary deficits.

    Calculation of Maintanence Fluid RequirementsThe following calculations approximate the maintenance fluid requirement of well children according to weight in kg. (Holliday-Segar calculator)

    Weight Total fluids Infusion rate

    First 10 Kgs 100 ml/kg 4 mls/kg/hour

    Subsequent 10 Kgs 50 ml/kg 2 mls/kg/hour

    All additional Kg 20 ml/kg 1 mls/kg/hour

    Example: A Child of 29 kg will require:

    100mls/kg for first 10kg of weight 10 x 100 = 1000 mls

    50mls/kg for second 10kg of weight 10 x 50 = 500 mls

    20mls/kg for all additional weight 9 x 20 = 180 mls

    Total = 1680 mls

    Rate= 1680/24 = 70mls/hour

    Composition of commonly used intravenous solution

    Osmolality Na content Osmolality Tonicity

    Fluid (mOsm/l) (mmol/l) compared to plasma

    Deficit

    • A child’s water deficit in mls can be calculated following an estimation of the degree of dehydration expressed as % of body weight.

    Example: A 10kg child who is 5% dehydration has a water deficit of 500mls.

    Maintenance

    100mls/kg for first 10 kg = 10 × 100 = 1000mls

    Infusion rate/hour = 1000mls/24 hr = 42mls/hr

    Deficit (give over 24hours)

    5% dehydration (5% of body water): 5/100 × 10kg × 1000mls = 500mls

    Infusion rate/hour (given over 24 hrs) = 500mls/24 hr = 21mls/hr

    • The deficit is replaced over a time period that varies according to the child’s condition. Precise calculations (e.g. 4.5%) are not necessary. The rate of rehydration should be adjusted with ongoing clinical assessment. • Use an isotonic solution for replacement of the deficit, e.g. 0.9% saline. • Reassess clinical status and weight at 4-6hours, and if satisfactory continue. If child is losing weight, increase the fluid and if weight gain is excessive decrease the fluid rate. • Replacement may be rapid in most cases of gastroenteritis (best achieved by oral or nasogastric fluids), but should be slower in diabetic ketoacidosis and meningitis, and much slower in hypernatremic states (aim to rehydrate over 48-72 hours, the serum Na should not fall by >0.5mmol/l/hr).

    Ongoing losses (e.g. from drains, ileostomy, profuse diarrhoea) • These are best measured and replaced. Any fluid losses > 0.5ml/kg/hr needs to be replaced. • Calculation may be based on each previous hour, or each 4 hour period depending on the situation. For example; a 200mls loss over the previous 4 hours will be replaced with a rate of 50mls/hr for the next 4 hours). • Ongoing losses can be replaced with 0.9% Normal Saline or Hartmann’s solution. Fluid loss with high protein content leading to low serum albumin (e.g. burns) can be replaced with 5% Human Albumin.

    • The daily sodium requirement is 2-3mmol/kg/day. • Normal serum sodium is between 135-145mmol/l.

    Hypernatremia • Hypernatremia is defined as serum Na+ > 150mmol/l, moderate hypernatremia is when serum Na+ is 150-160mmol/l, and severe hypernatremia is when serum Na+ > 160mmol/l. • It can be due to: • water loss in excess of sodium (e.g. diarrhoea) • water deficit (e.g. diabetes insipidus) • sodium gain (e.g. large amount of NaHCO3 infusion or salt poisoning).

    • If the cause of the hypernatremia is central diabetes insipidus, it is advisable to consult Endocrinology team regarding management. • In hypernatremia the child appears sicker than expected for the degree of dehydration. • Shock occurs late because intravascular volume is relatively preserved. Signs of hypernatremic dehydration tend to be predominantly that of intracellular dehydration and neurological dysfunction.

    ManagementThis will depend on the cause of hypernatremia. For hypernatremic dehydration with Na+> 150mmol/l • If the patient is in shock, give volume resuscitation with 0.9% Normal saline as required with bolus/es. • Avoid rapid correction as this may cause cerebral oedema, convulsion and death. • Aim for correction of deficit over 48-72 hours and a fall of serum sodium concentration not more than 0.5mmol/l/hour. • Give 0.9% saline to ensure the drop in sodium is not too rapid. • Remember to also give maintenance and replace ongoing losses following the recommendation above. • Repeat blood urea and electrolytes every 6 hours until stable.

    Special considerations • A slower rate will be required for children with chronic hypernatremia (present for more than 5 days). • Calcium and glucose need to be checked as hypernatremia can be associated with hypocalcaemia and hyperglycemia, these conditions need to be corrected concurrently.

    Hyponatremia • Hyponatremia is defined when serum Na+ < 135mmol/l. • Hyponatremic encephalopathy is a medical emergency that requires rapid recognition and treatment to prevent poor outcome. • As part of the general resuscitative measures, bolus of 4ml/kg of 3% sodium chloride should be administered over 30 minutes. This will raised the serum sodium by 3mmol/l and will usually help stop hyponatremic seizures. • Gradual serum sodium correction should not be more than 8mmol/day to prevent osmotic demyelination syndrome.

    Calculating sodium correction in acute hyponatremia

    mmol of sodium required = (135-present Na level)× 0.6 × weight(kg)

    The calculated requirements can then be given from the following available solutions dependent on the availability and hydration status:

    0.9% sodium chloride contains 154 mmol/l

    3% sodium chloride contains 513mmol/l

    • Children with asymptomatic hyponatremia do not require 3% sodium chloride treatment and if dehydrated may be managed with oral fluids or intravenous rehydration with 0.9% sodium chloride. • Children who are hyponatremic and have a normal or raised volume status should be managed with fluid restriction. • For Hyponatremia secondary to diabetic ketoacidosis; refer DKA protocol.

    POTASSIUM DISORDERS

    • The daily potassium requirement is 1-2mmol/kg/day. • Normal values of potassium are: • Birth - 2 weeks: 3.7 - 6.0mmol/l • 2 weeks – 3 months: 3.7 - 5.7mmol/l • 3 months and above: 3.5 - 5.0mmol/l

    Hyperkalemia • Causes are: • Dehydration • Acute renal failure • Diabetic ketoacidosis • Adrenal insufficiency • Tumour lysis syndrome • Drugs e.g. oral potassium supplement, K+ sparing diuretics, ACE inhibitors.

    Hyperkalemia Treatment Algorithm

    Drug doses: • IV Calcium 0.1 mmol/kg. • Nebulised Salbutamol: Age ≤2.5 yrs: 2.5 mg; Age 2.5-7.5 yrs: 5 mg; >7.5 yrs: 10 mg • IV Insulin with Glucose: Start with IV Glucose 10% 5ml/kg/hr (or 20% at 2.5 ml/kg/hr). Once Blood sugar level >10mmol/l and the K+ level is not falling, add IV Insulin 0.05 units/kg/hr and titrate according to glucose level. • IV Sodium Bicarbonate: 1-2 mmol/kg. • PO or Rectal Resonium : 1Gm/kg.

    Hypokalemia

    • Hypokalemia is defined as serum Na+ > 3.4 mmol/l (Treat if < 3.0mmol/l or Clinically Symptomatic < 3.4 mmol/l) • Causes are: • Sepsis • GIT losses - diarrhoea, vomiting • Iatrogenic- e.g. diuretic therapy, salbutamol, amphotericin B. • Diabetic ketoacidosis • Renal tubular acidosis • Hypokalaemia is often seen with chloride depletion and metabolic alkalosis.

    • Refractory hypokalaemia may occur with hypomagnesaemia.

    Treatment • Identify and treat the underlying condition. • Unless symptomatic, a potassium level of 3.0 and 3.4 mmol/l is generally not supplemented but rather monitored in the first instance. • The treatment of hypokalaemia does not lend itself to be incorporated into a protocol and as a result each patient will need to be treated individually.

    Oral Supplementation • Oral Potassium Chloride (KCL), to a maximum of 2 mmol/kg/day in divided doses is common but more may be required in practice.

    Intravenous Supplementation (1gram KCL = 13.3 mmol KCL) • Potassium chloride is always given by IV infusion, NEVER by bolus injection. • Maximum concentration via a peripheral vein is 40 mmol/l (concentrations of up to 60 mmol/l can be used after discussion with senior medical staff). • Maximum infusion rate is 0.2mmol/kg/hr (in non-intensive care setting). Intravenous Correction (1gram KCL = 13.3 mmol KCL) • K+ < 2.5 mmol/L may be associated with significant cardiovascular compromise. In the emergency situation, an IV infusion KCL may be given • Dose: initially 0.4 mmol/kg/hr into a central vein, until K+ level is restored. • Ideally this should occur in an intensive care setting.
