A & E Flashcards
What preparations should be made for an admission of a major trauma case?
Inform trauma team
Prepare resuc room
Prepare fluids and O -ve blood
Who forms the trauma team?
Anaesthetist
Surgeons
Orthopaedics
What is a fast scan?
rapid bedside USS assessement
What BP should you aim for in trauma patients?
Aim for 90 systolic (permissive hypotensive resuscitation) - helps blood to clot
When might you not want to follow permissive hypotensive resuscitation and bring the BP up more?
hx HTN/ cardiac disease
hx cerebrovascular disease, carotid artery stenosis, poor renal function
Define shock
Medical emergency in which organs and tissues are not receiving adequate perfusion of blood
What is MAP equation?
Diastolic + (Systolic-diastolic)/3
What is the minimum MAP needed to perfuse your organs?
70
How are CO, BP and SVR linked?
BP= CO X SVR
What sats do you aim for in COPD?
88-92%
What are the criteria for anaphylaxis?
1) Sudden onset, rapid progression of sx
2) Life threatening airway/breathing/circulation problem
3) Skin/mucosal changes
What test can be used post-anaphylaxis to confirm dx?
Tryptase (1-6h post anaphylaxis)
What is the dose of adrenaline for anaphylactic shock?
0.5mg IM
What drugs do you give following adrenaline in anaphylactic shock?
Chlorphenamine IV and hydrocortisone IV
What dose of adrenaline is used in cardiac arrest?
1mg IV (between second and third shock)
What drug is used to tx a patient in VT who is not displaying adverse features?
Amiodarone
What drugs are used to control AF in primary care?
beta blocker
CCB (diltiazem, verapamil)
Which three things make up cushings triad?
1) Altered respirations (decreased)
2) Widening pulse pressure (systolic htn)
3) Bradycardia
What is cushings reflex?
Physiological response to raised ICP
What is first line tx for angina control?
Beta blocker and/or CCB
and aspirin
ECG findings in PE
Tachycardia
RBBB
R axis deviation
S1Q3T3
Tx for hypothermia
Warm fluids/ O2
Bladder/peritoneal lavage
Bear hugger device
What value is a marker of carbon monoxide poisoning?
Carboxyhaemoglobin
Which cardiac enzymes can be measured as markers of ACS?
Troponin T
CKMD
(AST, CK)
What drug can be given IV as part of the major blood loss protocol?
Transexamic acid (if less than 3h from injury)
What are the criteria for PCI in STEMI?
Present within 12h of sx onset
and
PCI available within 2h of first medical contact
What drugs do you give initially in STEMI?
Aspirin 300mg Ticagrelor Morphine GTN spray O2
What score can be used to risk assess pts with NSTEMI?
GRACE score
Mx for severe pulmonary oedema
O2
Diamorphine IV
Furosemide IV
GTN spray (unless BP less than 90)
What is the most common cause of broad complex tachycardia?
VT
What should you do in unstable VT?
DC cardioversion (X3) Then amiodarone followed by more shocks
How do you manage torsades de points if caused by congenital long QT?
Beta blockers
How to tx torsades de pointes caused by acquired long QT?
Stop predisposing drugs
Correct hypokalaemia
Give magnesium sulphate
What can precipitate AF?
Hyperthyroidism
Alcohol
How do you manage SVT?
Vagal manoeuvres
Adenosine
How do you treat a bradycardic pt with adverse signs?
Atropine IV
What factors would make you consider a bradycardic patient at risk of asystole?
Recent asystole
Mobitz II AV block
Complete heart block with broad QRS
How would you treat a bradycardic patient deemed at risk of asystole or is unstable and hasn’t responded to initial atropine?
Repeat atropine
Transcutaneous pacing
Consider adrenaline
Seek expert help to arrange transvenous pacing
