respiratory Flashcards
drugs causing fibrosis
methotrexate amiodarone sulfasalazine gold nitrofurantoin
COPD - general management
smoking cessation
annual flu jab
one-off pneumococcal
LTOT, lung volume reduction surgery in selected pts
first line bronchodilator for COPD?
how do you determine next step?
SABA or SAMA
next step determined by FEV1
2nd line COPD inhaler if FEV1 > 50%
LABA (eg salmeterol), or LAMA (eg tiotropium)
what kind of drug is salmeterol?
LABA
what kind of drug is tiotropium?
LAMA
2nd line COPD inhaler if FEV1 < 50%
LABA + ICS (combo inhaler), or
LAMA
when to use theophylline for COPD?
if bronchodilators don’t work or if they can’t use inhalers
what can you use in COPD patients with a chronic productive cough?
mucolytics
symptoms of cor pulmonale
peripheral oedema
raised JVP
systolic parasternal heave
loud P2
management of cor pulmonale
loop diuretic for oedema
consider LTOT
ACEis, CCBs NOT recommended
what is a saddle embolus characteristic of?
PE
what are common symptoms of PE?
tachypnoea
crackles
tachycardia
low-grade fever
textbook triad of PE symptoms
pleuritic chest pain
dyspnoea
haemoptysis
but can present with any cardioresp symptom/sign
investigations if PE is ‘likely’
immediate CTPA - if delayed give LMWH in meantime
investigations if PE is ‘unlikely’
D dimer
if positive then immediate CTPA - if delayed give LMWH in meantime
PE wells scores
5+ - likely
0-4 - unlikely
CURB-65
confusion urea 8+ RR 30+ BP 90/60- 65+
care of CAP based on CURB65
0-1 - low - home care
2+ - intermediate - hosp
3+ - high - ICU
pneumonia - investigations
CXR
CURB65 2+ - blood + sputum cultures; pneumococcal + legionella urinary antigen tests
CRP monitoring to determine response to treatment
management of low-severity CAP (CURB65 0-1)
amoxicillin 5 days
management of moderate-high severity CAP (CURB65 2+)
dual abx: amoxicillin + macrolide (-mycin) 7-10 days
potential PE - investigations
CXR to rule out other causes
if still suspected then do wells
