Disclaimer These clinical guidelines represent the views of the North West and North Wales Paediatric Critical Care Network and North West and North Wales Paediatric Transport Service, which were produced after careful consideration of available evidence in conjunction with clinical expertise and experience. The guidance does not override the individual responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient. Management of acute wheeze in children under 2 years of age : This guideline is not appro-
priate for this age group. Early consultant involvement is recommended. Patients may respond clini-
cally to magnesium and aminophylline rather than salbutamol. There is no evidence to support High
flow humidified oxygen at present.
Clinical advice is always available from NWTS on a case by case basis. Please feel free to contact NWTS (01925 853 550) regarding these documents if there are any queries.

Guidelines for Management of Acute Severe Asthma in Children <2 years
Oxygen: Children with life-threatening asthma or SpO2 <94% should receive high-flow oxygen via a
tight-fitting face mask or nasal cannula at sufficient flow rates to achieve normal saturations. High-flow humidified oxygen (optiflow or vapotherm) may be considered early and used on HDU aiming for flow 2 L/kg/min.
Nebulisers: Oxygen-driven nebulisation is recommended
Salbutamol: 2 to 5yrs 2.5mg 5yrs 5mg
Ipratropium bromide Under 12yrs 250 micrograms Over 12yrs 500 micrograms Combining nebulised ipratropium bromide with nebulised β2-agonist produces significantly more bronchodilatation than β2agonist alone. If a child has poor response to initial dose of β2agonist subse-quent doses should be given in combination with ipratropium every 20 minutes for the first hour then four hourly.
Steroids: Prednisolone: 2mgkg od started within 1 hour of presentation Max 40mg unless on maintenance steroids when max dose is 60mg Hydrocortisone: 4 mg/kg 6 hourly intravenously (max 100 mg per dose) started within 1 hour of presentation Higher doses may be given in patients on maintenance steroids. Benefits apparent within 3-4 hours. Oral and intravenous steroids are of equivalent efficacy so intravenous steroids should be reserved for those unable to retain oral medications or most severely affected. Continue until clinically improved. Tapering unnecessary unless course of steroids continues for >14 days.
Magnesium sulfate (unlicensed): 40mg/kg (max 2g) (0.16mmol/kg, max 8mmol) intravenous-
ly over 20 min. For ease of prescribing and administration, doses are banded according to patient weight (see page 10). In practice this is first intravenous therapy used as it is safe and causes less tachycardia. Dose may be repeated in severe cases.
Intravenous Salbutamol: Bolus: Over 2 years of age 15 microgram/kg (MAX DOSE 250 microgram). Give over 10 mins
Infusion: 1-2 microgram/kg/min (Rarely doses as high as 5microgrm/kg/min may be used on PICU) Start at 2 micrograms/kg/minute
Patients should be on continuous cardiac monitoring & have minimum of 12 hourly U&Es. Nebulised β2
-agonists should be continued 4 hourly whilst patient is receiving intravenous salbutamol unless there are signs of salbutamol toxicity when they should be stopped. Salbutamol (nebulised or iv infusion) may cause a marked metabolic and lactic acidosis especially if patient is underfilled due to poor fluid intake and increased insensible losses.
NB: Doses above 2microgram/kg/min MUST be discussed with paediatric/anaesthetic consultant and NWTS as they are associated with significant toxicity
Aminophylline Loading dose: 5 mg/kg over 20 min (Omit if on oral theophyllines/aminophylline)
MAX DOSE 500mg
Infusion: Child 1month to 11 years: 1mg/kg/hr
Child 12-17 years: 0.5mg/kg/hr
Doses should be adjusted according to plasma theophylline levels (see page 13)
Intravenous salbutamol and aminophylline are incompatible. Salbutamol is compatible with magnesium

Guidelines for Management of Acute Severe Asthma in Children >2yrs
CXR should be considered in following situations
Surgical emphysema
Persistent unilateral signs suggesting pneumothorax, lobar collapse or consolidation
Previous pneumothorax
Severe/Life-threatening asthma not responding to treatment
Mechanically ventilated patient
Blood gas measurements
Should be considered if there are life-threatening features not responding to treatment
Normal or raised pCO2 indicates worsening asthma and imminent respiratory failure
Capillary blood gases will give an accurate measure of pH and pCO2
Children receiving large doses of β2agonists may develop a lactic acidosis which will resolve as the
dose of β2agonist is reduced, but may need fluid bolus . Discuss with consultant.
Antibiotics
The majority of acute asthma attacks are triggered by viral infections
Decision for antibiotics should be made on clinical grounds
Non-pharmacological interventions in acute severe asthma
Physiotherapy
No role in unventilated asthmatic patient
Alternative Diagnoses to consider in child that is not improving
Anaphylaxis/Allergic Reaction Severe Pneumonia Atypical Infection
Hyperventilation Inhalational injury Foreign body
Pulmonary oedema

Guidelines for Management of Acute Severe Asthma in Children >2yrs
Intubation in Acute Severe Asthma is a High Risk Procedure
Indications for
Intubation
Cardiac/Respiratory Arrest
Exhaustion
Hypoxia despite high flow oxygen
Worsening respiratory acidosis
Altered sensorium (agitation, confusion, decreased GCS)
Risks of
Intubation
Low oxygen reserve
Rapid desaturation
Difficult to ventilate
Relative hypovolaemia
Delayed gastric emptying
Pre-oxygenation
Most experienced available operator
Use largest fitting/cuffed ET tube
Anticipate hypotension. Good iv access
Give 20ml/kg fluid bolus pre-induction
Prepare vasopressors e.g. 0.1 ml/kg adrenaline
1 in 10,000 made up to 10 mls 0.9% sodium
chloride (use 1-2 ml aliquots to maintain BP)
Rapid sequence induction
eg ketamine + suxamethonium
Drugs for
induction
Avoid histamine-releasing drugs if possible (atracurium, thiopentone, morphine)
Use ketamine or fentanyl
Volatile anaesthetic agent available for immediately post-intubation
Other
bronchodilators
Ketamine
Volatile anaesthetic agents
Adrenaline 1:10,000 0.1ml/kg iv/via ETT can be used in extremis
On-going sedation Use ketamine and fentanyl or midazolam
Avoid morphine as causes histamine release

Guidelines for Management of Acute Severe Asthma in Children >2yrs
Difficulties with Ventilation in Acute Severe Asthma
REMEMBER HYPOXIA KILLS, HYPERCAPNOEA DOES NOT!
High Peak Pressures causing barotrauma/pneumothorax/air leaks/reduced cardiac
output
Strategies: Try PCV or square wave ventilation
Limit Pmax(<35-40)
Permissive hypercapnia (pH>7.15)
Large, cuffed ETT will reduce resistance and leak
Keep muscle relaxed initially especially whilst high pCO2
Incomplete Expiration Slow emptying of alveolus causes poor gas exchange,
progressive gas trapping and ↑ residual volume
Strategies: Try low respiratory rates 10-20 and long expiratory times (I:E ratio ≥1:3 )
Manual decompression (disconnect ETT and manually compress chest)
Physiotherapy with saline lavage may help but use slow bagging rate
Intrinsic PEEP
Aim to match extrinsic PEEP to intrinsic PEEP to reduce gas trapping
Mucus Plugging
Suction and physiotherapy with saline lavage (can make worse if inadequately
sedated). In extreme cases, instillation of Dornase Alpha may improve severe mucous
plugging.
Discuss EARLY with NWTS

Guidelines for Management of Acute Severe Asthma in Children >2yrs
Discontinuing Intravenous Bronchodilators
Aminophylline: Elimination half-life 3-5 hours
Reduce dose by 50% of original dose every 6 hours
After discontinuing infusion, aminophylline will be cleared within 24hours
Salbutamol: Elimination half-life 4-6 hours
Reduce dose by 1microgram/kg/min every 6 hours
After discontinuing infusion, salbutamol will be cleared within 24 hours
NB: Substantial systemic absorption of salbutamol occurs via GI tract
when administered by inhalation so intravenous infusions should be
discontinued before stopping nebulised salbutamol
Patients should receive nebulised β2agonists every 2 hours and nebulised ipratropium
bromide every 4 hours whilst weaning off intravenous bronchodilators.
NB: Rebound may occur 24—48 hours after stopping either infusion so observe in hospi-
tal for this time. Some patients with particularly brittle asthma may require a slower
weaning regime.
Criteria for reducing bronchodilator therapy
Normal respiratory effort
Normal ability to speak
Reduction in oxygen requirement
Discharge planning after severe asthma attack:
Check inhaler technique
Start or review dosage of preventer treatment
Written asthma plan for subsequent attacks with clear instructions about use of bronchodila-
tors and need to seek urgent medical attention if worsening symptoms
Contact GP to arrange Primary care follow up within 48 hours
Paediatric team follow up within 2 months
Refer to Paediatric Respiratory Specialist if life-threatening features, required intra-
venous aminophylline or salbutamol or invasive ventilation.

Management of acute wheeze in children under
2 years of age This guideline is not appropriate for use in children under the age of 2 years. In such children, a
number of different diagnoses need to be considered and the response to treatment is variable.
Such children should be managed on an individualised basis and early consultant involvement
should be obtained.
If intravenous salbutamol is given to children under 2 years the loading dose should be
5 microgram/kg
Children under two years with a clinical picture consistent with asthma may respond better to mag-
nesium sulphate and aminophylline rather than salbutamol
Severe asthma Previous near-fatal asthma
Previous hospital admission for asthma
Requiring 3 or more classes of asthma medication
Repeated attendances at emergency department for asthma care
History of anaphylaxis
Plus Adverse behavioural/psychological features
Poor compliance
Failure to attend appointments
Fewer GP contacts
Self-discharge from hospital
Psychosis, depression, psychiatric illness or deliberate self harm
Alcohol or drug abuse
Obesity
Learning difficulties
Looked after children
Staff should have a lower threshold for admission to hospital for children with above risk
factors
Patients at risk of near-fatal/fatal asthma

Appendix 1: Additional Drug Information
Magnesium
Nebulised Magnesium: There is some limited evidence to support the use of nebulised magnesium in
addition to standard treatment (Cochrane review 2017) and its use does not seem to be associated with
adverse events.
Intravenous Magnesium Sulfate (unlicensed)
This can be given anywhere in the hospital if needed acutely. If the patient improves, they can continue
to be managed within the general ward environment. In practice this is often first intravenous therapy
used as is safe and causes less tachycardia.
All children who receive intravenous magnesium sulfate must be admitted to hospital.
There is some evidence that higher doses of magnesium may be of benefit clinically but this is not cur-
rently recommended in the BTS guidelines. In practice repeating the dose 1-2 hours after initial dose is
clinically safe. Patients requiring multiple doses should be discussed with NWTS.
Form: Magnesium sulfate 50% injection containing 500mg/ml of magnesium sulfate. This is
available in 2ml and 10ml ampoules. Caution if using other strengths as the table below will not be ap-
plicable
Dose: 40mg/kg over 20 minutes. The maximum dose is 2g. Can be administered centrally or pe-
ripherally. Dilute volumes below to 20ml for administration. Doses are banded by weight below for
ease of prescribing and administration.
Contra-indications: Myasthenia gravis
Severe renal impairment
Overdose: Hypermagnesaemia. Dependent on the size of the overdose, progressive muscle
weakness, significant hypotension and ultimately respiratory failure have been reported.

.
Intravenous Salbutamol for Severe/Life-threatening Asthma
A bolus dose is recommended whilst the infusion is being drawn up (as infusion can take time to
prepare) to minimise delays, however this is not required if there is no delay in starting the
infusion.
Form: Salbutamol 1mg/ml Injection.
Bolus IV Salbutamol < 2 years of age 5 microgram/kg
>2 years of age 15 microgram/kg
(MAXIMUM DOSE 250 microgram)
Give over 10 minutes. Dilute injection to 50 microgram/ml (1ml of salbutamol 1mg/1ml diluted to
20ml with water for injection, sodium chloride 0.9% or glucose 5%)
15microgram/kg bolus over 10 minutes is equivalent to 1.5 microgram/kg/min infusion for the
same period
Continuous IV infusion: 1 to 2 microgram/kg/minute (Rarely doses up to 5microgram/
kg/min can be given on PICU)
Usual starting dose is 2micrograms/kg/min
Doses >2micrograms/kg/min should be used with extreme caution especially in
patients > 50kg as there is an increased incidence of side effects. We would strongly advise dis-
cussion with NWTS if increasing infusion above 2microgram/kg/min.
High doses of salbutamol (ie 3-5 microgram/kg/min) may cause tachycardia and SVT
without any additional benefit.
Management of SVT following Salbutamol Infusion
SVT has been reported in patients receiving salbutamol loading doses and infusions
at the higher dose range. Adenosine can cause bronchospasm in known patients
with asthma so should be used with caution in acute severe asthma. Please discuss
with NWTS/ Paeds cardiology consultant on call for further advice.
NOTE: CRASHCALL currently gives values for central administration of
salbutamol. If use of this is planned please discuss with NWTS first.

Guidelines for Management of Acute Severe Asthma in Children
Salbutamol infusion for Peripheral administration:
Draw up 10 mg of salbutamol (= 10ml of salbutamol 1 mg/ml)
Make up to 50mls with 5% glucose or 0.9% sodium chloride
Final concentration = 10 mg in 50 ml i.e. 200 micrograms/ml salbutamol
PERIPHERAL infusion rate: 0.3ml/kg/hr = 1microgram/kg/minute.
Example Dose Calculation:
For a 30kg child to run the infusion at 2microgram/kg/minute:
2microgram/kg/minute x 30kg = 60microgram/minute
60microgram/minute x 60minutes = 3600microgram/hour
Infusion contains 200microgram in 1ml therefore to calculate ml/hour:
3600 microgram/200microgram x 1ml = 18ml per hour

Aminophylline infusion for Peripheral administration: Draw up 500mg of aminophylline and add to 500mls 0.9% sodium chloride
Final concentration = 500mg in 500mls i.e. 1mg/ml aminophylline
Aminophylline is compatible with up to 40mmol/litre of Potassium chloride
Loading Dose: 5mg/kg over 20 mins (max dose 500mg). Omit if on oral theophyllines
Infusion rate: 1 month to 11 years 1mg/kg/hr = 1ml/kg/hr
12-17 years 0.5mg/kg/hr = 0.5ml/kg/hr
Therapeutic monitoring: Check levels at 4-6 hours until stable and then every 24 hours
Therapeutic range 10-20mg/l
Plasma levels correlate well with clinical effect but NOT with toxicity
Response to monitoring: <5mg/L Increase dose by 50% and recheck in 6 hours
5-15mg/L Continue. Recheck 24 hours
15-20mg/L Half infusion rate and recheck in 6 hours
