Respiratory, GI, Growth, Metabolic Flashcards
Key investigations for asthma
PEFR
Spirometry + Reversibility testing
FeNO test
Respiratory symptoms/signs increasing the likelihood of asthma over other resp diseases
Cough and Wheeze
Hx atopy
Wheeze on auscultation
Responsive to therapy
Features of acute severe asthma exacerbation
SpO2<92% PEFR 33-50% Tachycardia and Tachypnoea Can't complete sentences in one breath Too SoB TO SPEAK
Features of life-threatening asthma
SPO2<92% PEFR<33% Silent, poor effort, exhaustion Hypotension Confusion Normal or raised PCO2 Cyanosis
For mild asthma exacerbation what can you give?
6-8 puffs of salbutamol inhaler
1puff= 100mcg
If tolerated then go home on this for 48 hours
What is the maximum number of salbutamol puffs recommended for home in ?Acute asthma
2-4 puffs
6+ then they need to come hospital
Acute asthma management (>5 years)
Nebulised salbutamol 5mg BTB
Nebulised ipratropium 250mcg every 5 mins
Prednisolone 30-50mg 3 days (or hydracortisone 100mg IV)
MGSO4 added to Salbutamol
Aminophylline or IV salbutamol
What time between inhalers after an acute exacerbation of asthma would indicate it is safe to discharge
> 4 hours apart
Aims of asthma control
No waking at night
No need for reliever therapy
No limitations on activity
Step down therapy once objectives are achieved
How many uses of SABA a week would suggest asthma therapy needs to be intensified
> /=3
BTS Asthma guidelines
1) SABA
2) Low dose ICS
LTRA if <5
3) Increase ICS or add LTRA or LABA
4)Oral steroids, theophylline
NICE Asthma guidelines
SABA-> + ICS low dose -> +LTRA -> Stop LTRA IF NOT HELPING -> +LABA/MART
If <5 years then SABA + 8 WEEK TRIAL of ICS then consider LTRA
Example of a LTRA
Monteleukast
Example of a low dose ICS
Clenil Modulite
What is Maintenance and Reliever Therapy
LABA and ICS In one inhaler
Indications for starting an asthmatic child on both SABA and ICS (According to NICE)
If symptoms > 3X a week or waking at night
Peak age for Bronchiolitis
3-6 months
Cause of Bronchiolitis
RSV (Maybe other viruses)
Inflammation and narrowing of airways in lungs because of infection
Presentation of bronchiolitis
Harsh cough, Fever, High pitched wheeze bilaterally, Fine inspiratory crackles, SOB, Poor feeding
YOUNG <2 Years
When do the symptoms of Bronchiolitis peak
4-5 days from onset
Indications for admission of bronchiolitis
THINK FEEDING OR OXYGEN SUPPORT
Dehydration- No wet nappy for 12 hours Marked recessions/grunting Apnoeic Milk/Fluids<50% normal Exhausted Spo2<92%
Management of moderate Bronchiolitis
NG feed
Nasal cannula-> CPAP-> Intubate
+/- Fluids
Management of severe Bronchiolitis
HDU/PICU
CPAP/Ventilation/IV fluids
Severe bronchiolitis
Worsening respiratory distress Respiratory acidosis Apnoea Dehydration Risk Factors
