Breathlessness Flashcards
(34 cards)
Definition of sepsis
Infection + adverse host reaction (organ failure, SOFA >=2)
Quick assessment of organ f(x) for sepsis
Lungs: O2 sats
Heart: MAP
Liver: Bilirubin
Haem: Platelets
Kidneys: Creatinine
CNS: GCS
Differential for wheeze
Asthma
COPD
Heart failure
Anaphylaxis
Differential for stridor
Epiglottitis
Anaphylaxis
Trauma
Foreign body/tumour
Differntial for reduced air entry + clear chest
Pneumothorax
Pleural effusion
Differential for crepitations
Pneumonia
Pulmonary oedema
Bronchiectasis
Pulmonary fibrosis
Differential for SOB + clear chest
PE
DKA
Pneumocystis jirovecii pneumonia
CNS causes
Anaemia
Drugs e.g. salicylates
Hyperventilation (e.g. panic attack)
Signs and symptoms of anaphylaxis
Itching, urticaria
Angioedema
D+V
Wheeze, laryngeal obstruction
Tachycardia, hypotension (SHOCK)
Mimics of anaphylaxis
Carcinoid
Phaeochromocytoma
Systemic mastocytosis
Hereditary angioedema
Acute management of anaphylaxis
Secure airway, ?intubate, 100% O2
adrenaline IM
chlorphenamine and hydrocortisone IV
Saline IV (titrate against blood pressure)
Long-term management of anaphylaxis
Mast cell tryptase at 1-6h
Monitor 4-6h for biphasic reaction + safety net (more likely if happened before)
2-3d course of oral prednisolone TTO
Allergy clinic F/U if first episode
Adrenaline dose anaphylaxis
0.5mg (0.5ml of 1:1000) IM
Repeat every 5 min
Hydrocortisone dose anaphylaxis
200mg IV
Chlorphenamine dose anaphylaxis
10mg IV (of 1:1000)
Features of severe asthma attack
PEF 33-50% of expected
Unable to complete sentences
RR >25
Pulse >110
Features of life-threatening asthma attack
PEF <33%
Feeble/absent respiratory effort
Cyanosis
Altered consciousness
Hypotension, arrhythmia
Normal/high PaCO2
PaO2 <8; sats <92%
Management of acute asthma
Salbutamol nebuliser
Hydrocortisone/prednisolone
Fluids
If infx suspected, abx
If severe, ipratropium bromide
Reassess every 15min, incl. ECG/ABG
If unresponsive to therapy, magnesium sulfate (senior consultation)
If remains unresponsive, consider aminophylline (ICU)
Salbutamol dose acute asthma
5mg nebulisedrepeated every 15-30min or 10mg/h continuously
Steroid doses acute asthma
100mg IV hydrocortisone
OR
40-50 mg PO prednisolone
Ipratropium bromide dose acute asthma
0.5mg/4-6h nebulised
TTO for asthma
5-7d of 40-50mg oral prednisolone
GP f/u
Respiratory clinic f/u
Management of acute exacerbation of COPD
Salbutamol + ipratropium bromide
O2 > titrate to sats of 88-92%
Prednisolone
Antibioticsif infective
If unresponsive, consider aminophylline/NIV (not intubation unless haemodynamically unstable/unable to protect airway)
Steroid dose acute COPD
30mg PO prednisolone (7-14d)
Nebuliser doses COPD
5mg/4h salbutamol
0.5mg/4-6h ipratropium
