RESP - Asthma Flashcards
What is the significance of a silent chest?
The airways are so tight that it is not possible for the child to move enough air through the airways to even create a wheeze. It is associated with reduced respiratory effort due to fatigue.
How is a diagnosis made in kids below the age of 5?
Clinical judgement. A diagnosis is usually not made for kids below the age of 2.
How is a diagnosis made in kids between the ages of 5-16?
- Spirometry with Bronchodilator Reversibility Testing.
2. If (1) is normal or (1) shows obstructive picture with negative Bronchodilator Reversibility Testing, FeNO test.
Management of Chronic Asthma : BTS Guidelines.
KIDS BELOW THE AGE OF 5 (4).
- SABA as required.
- Low-Dose ICS or LRA.
- Low-Dose ICS and LRA.
- Specialist Referral.
Management of Chronic Asthma : BTS Guidelines.
KIDS BETWEEN 5-12 YEARS (7).
- SABA as required.
- Low-Dose ICS.
- LABA e.g. Salmeterol (continued only if there is a good response).
- Moderate-Dose ICS.
- LRA or Oral Theophylline.
- High-Dose ICS.
- Specialist Referral.
Management of Chronic Asthma : BTS Guidelines.
KIDS ABOVE THE AGE OF 12.
Same as adults.
Management of Chronic Asthma : NICE Guidelines.
KIDS BELOW THE AGE OF 5 (4).
- SABA.
- 8 Week Trial of Moderate-Dose ICS (stop after 8 weeks and monitor symptoms to check if there might be an alternative diagnosis).
- LRA.
- Specialist Referral.
Management of Chronic Asthma : NICE Guidelines.
KIDS BETWEEN 5-16 YEARS.
- SABA.
- Low-Dose ICS.
- LRA.
- LABA instead of LRA (stop LRA if it didn’t help).
- SABA + MART (Low-Dose ICS).
- SABA + MART (Moderate-Dose ICS).
- SABA + MART (High-Dose ICS) or Theophylline Trial or Specialist Referral.
Why can a patient be started on Step 2? (3)
- Cannot be controlled on Step 1.
- Newly-diagnosed Asthma with symptoms lasting more than 3 weeks.
- Experiences night-time waking.
Doses of ICS in Paediatrics.
Low - Less than 200mcg Budesonide.
Moderate - 200-400mcg Budesonide.
High - More than 400mcg Budesonide.
Concern with Inhaled Steroids.
Evidence : Slightly reduces growth velocity and cause a small reduction in adult height up to 1cm when used long-term (dose-dependent).
Management of Acute Asthma/Viral Induced Wheeze (4).
- Supplementary Oxygen Therapy (if O2 Saturation is below 94% or obvious effort).
- Bronchodilators e.g. Salbutamol, Ipratropium, Magnesium Sulphate.
- Steroids e.g. Prednisolone (Oral), Hydrocortisone (IV).
- Antibiotics (if bacterial cause) e.g. Amoxicillin, Erythromycin.
Bronchodilator Therapy in Acute Asthma/Viral Induced Wheeze (4).
- Inhaled/Nebulised Salbutamol (SABA).
- Inhaled/Nebulised Ipratropium Bromide (SAMA).
- IV Magnesium Sulphate.
- IV Aminophylline.
Referral to Hospital : Paediatric Acute Asthma/Viral Induced Wheeze.
1 puff of Salbutamol is given every 30-60 seconds, up to a maximum of 10 puffs. If symptoms are not controlled, refer.
Management of Moderate/Severe Acute Asthma (8).
- Salbutamol Inhaler.
- Nebulised Salbutamol/Ipratropium Bromide.
3 Oral Prednisolone (1mg/kg/day for 3 days). - IV Hydrocortisone.
- IV Magnesium Sulphate.
- IV Salbutamol.
- IV Aminophylline.
- Call Anaesthetist and ITU to intubate and ventilate.
