Resp Flashcards
what is a pneumothorax
air in the pleural space
pneumothorax classification based on causes
a) primary: tall, thin, young healthy male smoker
b) secondary: pre-existing condition (COPD, asthma, CF)
c) traumatic
pneumothorax symptoms
SOB
pleuritic chest pain
pneumothorax signs
- hyper-resonant
- reduced chest expansion
- reduced breath sounds
tension pneumothorax presentation
- trachea deviates away from the lesion
- tachycardia, hypotension, respiratory distress
pneumothorax investigations
- chest x-ray: black
- CT CAP if trauma
primary pneumothorax management
< 2cm: observe and discharge
> 2cm: needle aspiration, chest drain if unsuccessful
secondary pneumothorax management
< 2cm: needle aspiration, chest drain if unsuccessful
> 2cm: chest drain
< 1cm: oxygen and observe
tension pneumothorax management
emergency do not investigate!!
i. needle decompression (5th ICS) + oxygen
-> open thoracostomy in trauma
ii. chest drain + analgesia after decompression
recurrent or persistent pneumothorax treatment
VATS (cardiothoracic referral)
how to check chest drain is in pleural cavity
water rises on inspiration, falls on expiration
most common community acquired pneumonia
streptococcus pneumoniae (+ve)
community acquired pneumonia associated with COPD
haemophilus influenza (-ve)
community acquired pneumonia associated with IVDUs
staphylococcus aureus (+ve)
community acquired pneumonia associated with recent flu
staphylococcus aureus
community acquired pneumonia associated with alcoholics
klebsiella (-ve)
mycoplasma pneumonia associations and presentation
young uni students
atypical (dry cough, haemolytic anaemia)
legionella pneumophilia associations and presentation
airconditioning
atypical (hyponatraemia)
community acquired pneumonia associated with HIV
pneumocystis jirovecii
most common hospital acquired pneumonia
MRSA
pneumonia associated with bronchiectasis
pseudomonas aeruginosa, haemophilus
pneumonia symptoms
cough with productive green sputum
pleuritic chest pain
SOB
fever, rigours
pneumonia signs
reduced chest expansion
coarse crackles
dull percussion
increased vocal resonance
pneumonia investigations
- Bedside: sputum sample
- Bloods: FBC, U&Es, LFTs, CRP, culture, ABG
- CXR: consolidation
- Special: pleural fluid MCS
pneumonia severity score
CURB-65
confusion
urea >7
RR >30
Blood pressure < 90 systolic
65 or older
pneumonia management
CURB 0-1: outpatient amoxicillin
CURB 2: admit with amoxicillin + clarithromycin
CURB 3: admit with coamoxiclav + clarithromycin
-> amoxicillin covers typical
-> clarithromycin covers atypical
aspiration pneumonia antibiotic
metronidazole
MRSA pneumonia management
IV vancomycin
pneumonia management if penicillin allergy
doxycycline
pneumonia management for staphylococcus aureus
flucloxacillin + amoxicillin
aspiration pneumonia causes
intubation, surgery
swallowing difficulty (MS)
-> commonly affects right lobe
pseudomonas pneumonia management
IV gentamycin
additional medication for pneumonia patient with COPD
give prednisolone
pneumonia complications
- infection spread: effusion, sepsis, empyema (staph associated with abscess)
- structural: bronchiectasis, pneumothorax
pneumonia follow up test
CXR 6 weeks after
first line antibiotic for hospital acquired pneumonia (>48hrs hospital)
co-amoxiclav
what is bronchiectasis
irreversible bronchi dilatation
congenital causes of bronchiectasis
- cystic fibrosis (most common)
- Kartagener’s syndrome (bronchiectasis, inverted heart, sinusitis, infertility)
infective causes of bronchiectasis
- TB (most common worldwide)
- ABPA
bronchiectasis symptoms
- chronic productive cough
- copious amounts of white sputum
- haemoptysis
- SOB
bronchiectasis signs
- clubbing
- coarse crackles
bronchiectasis investigations
Bedside:
- sputum MCS (pseudomonas, haemophilus)
Bloods:
- routine bloods
- serum IgE (IgE + eosinophils -> ABPA)
Imaging:
- first line: CXR tram-lines
- diagnostic: HRCT chest signet rings
Special:
- genetic testing
- CF test
bronchiectasis management
- airway clearance with physiotherapy
- surgery if localised
bronchiectasis recurrent infections prophylaxis
azithromycin
bronchiectasis CXR sign
tram-track lines
bronchiectasis HRCT chest sign
signet rings
