A 5 year old boy presents with an acute exacerbation of asthma. On
examination there is reduced air entry bilaterally with expiratory wheeze.
He has tracheal tug, sub costal recession and is tachypnoeic. Initial pulse
oximetry reveals oxygen saturation of 85% on room air. He has had no
treatment prior to arriving in the emergency department.

SAQ 332
A 27 year old female presents with an acute exacerbation of her asthma.
Her observations are:
GCS 15
Temperature 37.2 degrees Celsius
HR 145
BP 105/60
RR 32
SaO2 88% on 15 l/min O2 via non-rebreathing mask
a) Outline how you would assess the clinical severity of her acute asthma. (30%)
b) Describe your management of this patient including reference to potential intubation and ongoing
ventilation. (70%)
Multiple previous admissions.
Previous ventilation for same.
Attacks refractory to treatment.
Steroid dependence.
Delayed presentation with maximal therapy at home.
Concurrent smoking.
Co-existing lung disease.
Increased respiratory effort
• Tachypnoea
• Accessory muscle use.
• Not able to speak normally.
Signs of hyperinflation
• I.e. small tidal volumes with splinted breathing.
• Pulsus paradoxus of more than 10mmHg.
Signs of pulmonary failure
• Cyanosis
• Obtundation / ALOC
• Systemic features of shock with hypotension and tachycardia.
• Dilated pupils.
Spirometry / peak expiratory flow rate (PEFR)
• Unable to perform spirometry or PEFR.
• Unable to blow 40% of predicted or previous best.(British Thoracic Society)
• Signs of hyperinflation.
• Complications such as tension pneumothorax.
• Normo-carbia or CO2 retention.
• Hypoxia.
• Concurrent metabolic acidosis.
Ventilator features
• Airway pressures in excess of 20 cm water.
• Patient feels stiff to bag with hand held device.
• Resuscitation bay with facilities for intubation.
• Non-invasive monitoring including continuous sats.
• Supplemental high flow oxygen.
• Adequate nursing and medical staff.
• IV access secured.
Definitive management
• Continuous nebulised salbutamol in increments of 5 mg each.
• Intravenous salbutamol as a slow push, 10 micrograms per kilogram.
• Ipratropium bromide (Atrovent) 0.5 mg nebulised once.
• MgSO4 nebuliser (local protocols)
• Consider a magnesium bolus of 10 mmol IV.
• Adrenaline nebulised or IV not superior to the above.
• May be used where salbutamol not available.
• Hydrocortisone 200 mg IV.
• Theophylline has little to offer those not suffering from COAD, may precipitate an arrhythmia, and is not to
be recommended.
• Correct electrolyte problems i.e. hypokalemia.
• Look for and treat complications, i.e. pneumothorax.
Supportive management
• The most vexing issue is that of intubation for ventilatory support.
• Indicated where ventilation or gas exchange fails, i.e., respiratory fatigue with obtundation and / or
worsening hypercapnia after a trial of NIPPV.
Optimal pre-oxygenation.
Fluid load
Suxamethonium 1.5 mg / kg IV.
Ketamine 1 mg / kg IV, unless contra-indications.
Employ a rapid sequence intubation technique with direct laryngoscopy.
As large an ETT as possible, secured.
Vecuronium after successful intubation, 0.1 mg / kg IV.
Morphine and midazolam infusion for sedation.
Ventilate to lesser tidal volume if required, 5 to 7 ml per kg.
Note the concept of permissive hypercapnia.
Set as long an expiratory time as possible for rate.
RR ~ 6
Modest PEEP of 2.5 to 5 cm water if tolerated.
Also place a NGT and IDC.
Consider arterial and central lines.
Maintenance fluids IV, i.e. dextrose saline at 100 ml/h.
• Where intubated, admit to ICU.
• Where not, ICU or a respiratory unit HDU.
• In our time of access block, continue a stay in resuscitation bay or transfer to another hospital.

1) Quantify amount:
Massive hemoptysis >600ml/24h
Exsanguinating hemoptysis > 1000ml total or > 150ml/hr
2) Wide differential diagnosis:
• Infection – bronchitis or pneumonia, also consider tuberculosis. (Bacterial, atypical, fungal).
• Neoplastic – primary or secondary, ca esophagus
• Vascular - Pulmonary embolism with lung infarct, AVmalformation, pulmonary edema, thoracic aortic
• Connective tissue disease – SLE, Goodpasture’s, Wegener’s, sarcoidosis, collagen vascular disease
• Vasculitis
• Congenital – CF (unlikely in this age group_
• Other – trauma, FB
• Underlying contributors - Coagulation disorder (anticoagulants, antiplatelets, alcoholism/liver disease),
immunocompromise (HIV, steroids)
(a) Assessment:
- quantify hemoptysis
- look for cause + contributors
- look for complications
• General historical features of haemoptysis – determine severity of haemoptysis:
o Frequency
o Volumes lost
o Description of blood – fresh v altered
o Ensure not from GIT or nose – non-pulmonary source
• Symptoms of complications of haemoptysis – anaemia:
o Lightheaded, fatigue, pre-syncopal, SOB etc
• Symptoms of potential underlying causes:
o Fever, purulent sputum, SOB, associated URTI symptoms – respiratory infection (bacterial, viral etc)
o Cough, night sweats, weight loss – TB
o Weight loss, SOB, symptoms of primary tumour elsewhere (bowel, breast etc) - malignancy
o Spontaneous bleeding form other sites – vasculitis, coagulation disorders
• Risk factors for potential underlying causes:
o Immunocompromised – infection, TB
o Smoking – primary malignancy
o Hx of previous malignancy (bowel, breast) – pulmonary metastases
o Risk factors for PE – immobility, recent surgery etc
o Hx of underlying / chronic lung disease – bronchiectasis
o Travel history, contacts infection, TB
o Hx of connective tissue disease / vasculitis
• Medications:
o Anticoagulants – warfarin
o immunosuppressants
• Smoking, IVDU, alcohol (liver dysfunction)
• General systems examination – focused on respiratory system
• General inspection: cachexia, jaundice, pallor
• Vital signs – gas exchange, hemodynamics
o Fever – infection
o Evidence of respiratory distress – HR, RR, SaO2
• Evaluate sputum to confirm haemoptysis
• Examine nose, upper airway for evidence of bleeding site
• Peripheral stigmata of potential underlying cause:
o Clubbing (bronchiectasis)
o lymphadenopathy – malignancy, TB
o Peripheral signs of vasculitis, Connective tissue disease
o stigmata of chronic liver disease
• Respiratory exam – evidence of consolidation, effusions
• Bedside:
o BSL, ECG – baseline
o WTU – haematuria – vasculitis, coagulation disorder
o ABG – assess ventilation, also check Hb
o Spirometry – baseline, assess underlying lung function
• Laboratory:
o FBC – Hb / Raised WCC – infection / Low platelets – clotting disorder
o ELFTS – baseline / evidence of other organ involvement (vasculitis)
o Coagulation profile – baseline / exclude as cause, ?D-dimer
o ESR – raised in malignancy, infection, connective tissues disease, vasculitis
o Sputum M/C/S, AFB and cytology
o BC if > 38.5
• Radiology:
o CXR – evidence of infection / effusions / malignancy / underlying lung disease
o CT chest – to further delineate infection / malignancy etc
o CTPA chest if need to exclude PE
• Other:
o If effusion present – pleurocentesis – fluid for M/C/S and cytology
o ?Bronchoscopy
(b) Disposition:
• Liaised with respiratory team
• Will be dependant on:
i. severity of haemoptysis
ii. whether the underlying cause is identified
iii. whether the patient is compromised by the haemoptysis or its cause
iv. the treatment required
• If cause found - treatment and disposition dependant on requirements of management and treatment
• If cause not identified at this point:
i. If more than mild haemoptysis, patient compromised requiring supportive care, serious / potentially
imminent life threatening cause suspected – then admit
ii. Otherwise – plan to discharge in liaison with respiratory team for early outpatient review +/- bronchoscopy.
