Resp Flashcards
Common cause of Bronchioloitis
RSV
What age does Bronchiolitis mainly occur
under 1yr, mainly under 6months
Typical pattern of bronciolitis
symptoms worsen days 1-5
day 5-7 no change
7-10 recovery period
treatment of bronchiolitis
usually no need
presentation of bronchiolitis
Coryzal symptoms: running or snotty nose, sneezing, mucus in throat and watery eyes. Signs of respiratory distress Dyspnoea Tachypnoea Poor feeding Mild fever (under 39ºC) Apnoeas are episodes where the child stops breathing Wheeze and crackles on auscultation
Signs of respiratory distress
Raised respiratory rate Use of accessory muscles of breathing Intercostal and subcostal recessions Nasal flaring Head bobbing Tracheal tugging Cyanosis (due to low oxygen saturation) Abnormal airway noises
common causes of croup
Parainfluenza (main one)
Influenza
Adenovirus
Respiratory Syncytial Virus (RSV)
presentation of croup
Increased work of breathing “Barking” cough, occurring in clusters of coughing episodes Hoarse voice Stridor Low grade fever
treatment of croup
Oral dexamethasone
unvaccinated child presenting with a fever, sore throat, difficulty swallowing that is sitting forward and drooling what is the likely diagnosis
Epiglottitis
Common cause of Epiglottitis
haemophilus influenza type B
Presentation of epiglottitis
Patient presenting with a sore throat and stridor Drooling Tripod position, sat forward with a hand on each knee High fever Difficulty or painful swallowing Muffled voice Scared and quiet child Septic and unwell appearance
Lx for epiglotittis
if patient is acutely unwell go straight to treatment
lateral x ray of neck can show thumb sign
Treatment for epiglitittis
secure airway
IV antibiotics (e.g. ceftriaxone)
Steroids (i.e. dexamethasone)
Lx for whooping cough (pertussis)
A nasopharyngeal or nasal swab with PCR testing or bacterial culture
Anti-pertussis toxin immunoglobulin G if cough has been present for more than 2 weeks
Treatment of whooping cough
Macrolides (azithromycin, erythromycin and clarithromycin) are beneficial in the early stages
What is the inheritiance pattern of CF
Autosomal recessive
Both parents are healthy, one sibling has cystic fibrosis and a second child does not have the disease, what is the likelihood of the second child being a carrier?
2/3
what is the screening for CF
newborn blood spot test
signs and symptoms of CF
failure to pass first poo within 24 hrs (usually first indicator of CF)
recurrent lower resp tract infections
failure to thrive
pancreatitis
Chronic cough Thick sputum production Recurrent respiratory tract infections Loose, greasy stools (steatorrhoea) due to a lack of fat digesting lipase enzymes Abdominal pain and bloating salty skin
Nasal polyps
Finger clubbing
Crackles and wheezes on auscultation
Lx for CF
Sweat test (gold standard) genetic testing for CFTR gene
2 main common colonises of patients with CF
Staph A
Pseudomonas
Management of CF
Chest physiotherapy several times a day is essential to clear mucus and reduce the risk of infection and colonisation
Exercise improves respiratory function and reserve, and helps clear sputum
High calorie diet is required for malabsorption, increased respiratory effort, coughing, infections and physiotherapy
CREON tablets to digest fats in patients with pancreatic insufficiency (these replace the missing lipase enzymes)
Prophylactic flucloxacillin tablets to reduce the risk of bacterial infections (particularly staph aureus)
Treat chest infections when they occur
Bronchodilators such as salbutamol inhalers can help treat bronchoconstriction
Nebulised DNase (dornase alfa) is an enzyme that can break down DNA material in respiratory secretions, making secretions less viscous and easier to clear
Nebulised hypertonic saline
Vaccinations including pneumococcal, influenza and varicella
what are typical features of viral induced wheeze (as opposed to asthma)
Presenting before 3 years of age
No atopic history
Only occurs during viral infections
what is the management of chronic asthma in under 5yrs?
- SABA as required
- Add inhaled steroid
- Add LABA
- increased inhaled steroid
refer for step 4
what is the management of asthma in 5-12yrs?
- SABA as required
- Add inhaled corticosteroid
- Add LABA (do not use with ICS)
- increase inhaled steroid
- use daily steroid table
steps 4 and 5 should be done by specialist?
