What do we give in infective exacerbation of COPD?
 amoxicillin doxycycline clarithromycin
Only to be used acutely not for prophylaxis
What prophylactic can we give in copd patients
Azithromycin
This is not for eveyone
Only if meds have been optimised
Patient is a non smoker
Patient Keeps getting hospitalised with exacerbations
Prolonged sputum production
Before starting need to have some work up liver function tests(not good if you don’t have good liver ) and ct thorax (to exclude other lung pathologies) and sputum culture and ecg to look for qt prolongation as can prolong the qt
250 three x a week
What is the dose of steroids we gave in COPD exacerbations?
Prednisolone 30 for five days
Do all COPD exacerbations receive antibiotics?
We only give if we suspect it’s infective so the sputum is pent or we suspect pneumonia because they have fever crackles or look very generally unwell we don’t just give antibiotics
The most common bacteria as virus responsible for infective exacerbation of COPD isn
H. Influenza
Rhino virus
Admission criteria copd
Low sats <90
Cyanotic
Confused (co2 retention)
Severe breathlessness
What class of drug is ipatrorpium?
SAMA
What class is of drug is tiotropium?
LAMA
Examples
Of LABA
Salmeterol/formetweol
Copd protocol for asthmatic features
Take SABA or SAMA prn
Ics + LABA regularly
If still not working can add a LAMA
(If taking a SAMA switch to Saba )
Copd protocol for no asthmatic features
Sama/saba
LAMA and LAbA regularly
If taking sama switch to SAba
What are the asthmatic features of COPD
Diurnal variation in peak expiratory flow >20%
Atopy
Previous diagnosis of asthma or atopy
Raised eosinophil count
Substantial variation in fev1 over time (at least 400 ml)
What is dirunal variation in asthma
Tends to be worse at night and early
Morning
Gets better in the afternoon
So it’s normal for asthma to have this variation and it helps to distinguish from similar causes like COPD the larger the gap could
Mean the greater the severity of the asthma
What the ration we use to measure obstructive diseases and what does it mean
FEV1/FVC ratio
Low ratio - obstructive
High - restrictive
In restrictive both values decrease but because they both decrease it cancels out so the ratio can be normal
In obstructive fev1 will be less because it’s decrease the amount of sir
FVC = size of the bottle
• FEV₁ = how fast the bottle empties in the first second
What should the normal spirometer values be
FEV1: >80% predicted
FVC: >80% predicted
FEV1/FVC ratio: >0.7
How to assess reversibility for spirometry test
To assess reversibility, administer 400 micrograms of salbutamol and repeat spirometry after 15 minutes:
Before that patient should not have had any treatment beforehand
Examples of restrictive diseases
Pulmonary edemas
Cancers
Fibrosis
What to do if u take IcS
Regular rinse mouth after taking
Reduce risk of candiadia
If taking theophyline classification what to be careful of
Have to reduce the dose with taking fluoroquinolone or macrolides
What is salmeterol
LABA!!!!!!!
CAP treatment
Low CuRb 0-2 - amoxicillin 5 days
If pen allergic clarithromycin
Moderated curb dual therapy if curb score >2
Point of care CrP test ?
Can be done in Gp for patients suspected of pneumonia not widely available
0-20 no abx
20-100 consider delayed abx
>100 deffo abx
Asthma management
Nebs set
Back to back
Iv magnesium 20 mins 2 mg (has a bronchodilator effect)(automatic admission as needs monitorin)
Aminophylline needs senior !!
Iv salbutamol (usually itu setting )
Intubation and ventilation
