Resus guidelines Flashcards
In the adult tachycardia (with pulse) algorithm, what are the adverse features that will influence which route to take? (4)
- Shock
- Syncope
- Myocardial ischaemia
- Heart failure
In tachycardia, if there are no adverse features (e.g. shock, heart failure), what do you need to look at on the ECG before choosing the management option?
If the QRS is broad or narrow
What constitutes a broad QRS?
> 0.12 seconds
If the patient has tachycardia, with a regular rhythm, and a narrow QRS, what is the treatment? (3)
- Vagal manoeuvres
- Adenosine 6mg rapid IV bolus (if no effect, give 12mg, and again if no effect)
- Monitor/record ECG continuously
If the patient has tachycardia, with an irregular pulse, and a narrow QRS, what is it most likely going to be?
Atrial fibrillation
What is the management of a patient with most likely AF - narrow QRS, tachycardia and irregular pulse? (3)
- Control rate with beta-blocker or diltiazem
- If in heart failure, consider digoxin or amiodarone
- Assess thromboembolic risk and consider anticoagulant
In a patient with tachycardia, regular rhythm and narrow QRS, if the treatment of vagal manoeuvres and adenosine don’t work (i.e. no sinus rhythm is achieved), what is the next option?
Seek expert help!
- possible atrial flutter so consider controlling rate e.g. beta blocker
What is the most likely cause of someone with tachycardia, regular rhythm, and narrow QRS who does achieve sinus rhythm after the treatment?
Probable re-entry paroxysmal SVT
if SVT recurs, treat again and consider anti-arrhythmic prophylaxis
If a patient has no adverse features and has tachycardia with pulse, but has a broad QRS, with a regular pulse, what is the management option?
Amiodarone 300mg IV or 20-60 minutes, then 900mg over 24 hours
(if it is known to be an SVT with bundle branch block, treat as for regular narrow-complex tachycardia)
What is the most likely cause of someone having an irregular rhythm tachycardia, with a broad QRS?
- AF with bundle branch block - treat as for narrow complex
2. Pre-excited AF, consider amiodarone
If the patient with tachycardia and a pulse, has got adverse features, e.g. myocardial ischaemia, and therefore is unstable, what is the management plan? (3)
- Synchronised DC shock - up to 3 attempts
- GET HELP
- Amiodarone 300mg IV over 10-20 minutes, repeat shock, then give amiodarone 900mg over 24 hours
To summarise, tachycardia in an unstable patient, what is the treatment?
Synchronised DC shock –> amiodarone 300mg IV (10-20 minutes) –> repeat shock –> amiodarone 900mg (24 hours)
To summarise, tachycardia, no adverse features, narrow QRS, regular rhythm, what is the treatment? (4)
- Vagal manoeuvre
- Adenosine 6mg IV rapid bolus
- If not worked - 12mg adenosine
- If not worked again - 12mg adenosine
- sinus rhythm returned, great, if not, ask for help!
To summarise, tachycardia, no adverse features, narrow QRS, irregular rhythm, what is the most likely diagnosis, and what is the treatment? (3)
Most likely atrial fibrillation
Treatment:
1. Beta blocker or diltiazem
2. If in heart failure consider digoxin or amiodarone
3. Assess thromboembolic risk and consider anticoagulation
To summarise, tachycardia, no adverse features, broad QRS, regular rhythm, what is the treatment?
If VT (or uncertain rhythm)
- amiodarone 300mg IV (20-60 minutes)
-amiodarone 900mg (24 hours)
If known to be SVT with BBB - treat as for regular narrow complex tachycardia (vagal manoeuvre, adenosine)
