Acute Care Flashcards
acute pain management
dilute 10mg of morphine in 0.9% saline to 10 mls (i.e. 1mg/1ml), and give in 1-2mg increments
standard PCA prescription
1mg morphine bolus
5 min lock out
Oral morphine to SC morphine = conversion factor
Divide by 2
Weak Opioid to Oral Morphine = conversion factor
Divide by 10
Oral Morphine to IV morphine = conversion factor
Divide by 3??
Some places say divide by 2??
how to calculate breakthrough dose for morphine
1/6th of the total daily dose
Initial management of DKA
Fluids
DKA protocol for changing IV to S/C insulin
Established subcutaneous therapy with long-acting insulin analogues (insulin detemir or insulin glargine) should be continued during Tx of DKA
Continue insulin infusion until blood-ketone concentration is below 0.3 mmol/litre, blood pH is above 7.3 and the patient is able to eat and drink; ideally give subcutaneous fast-acting insulin and a meal, and stop the insulin infusion 1 hour later.
HDU patient with some severe illness, how you monitor BP
Intra-arterial BP
infusion rate of insulin in DKA
0.1 units/kg/hour
first step in bradycardia algorithm
IV Atropine 500mcg
Next step if unsatisfied with response to one bolus of atropine
Repeat IV Atropine 500mcg up to 3mg. OR Transcutaneous pacing OR Adrenaline 5-10mcg min IV Isoprenaline 5mcg min IV

Tachycardia with pulse algorithm - step 1
Assess whether adverse features i.e. shock, myocardial ischaemia, HF, syncope
Tachycardia with pulse algorithm - if adverse features, next step
Synchronised DC shock - up to 3 attempts
Tachycardia with pulse algorithm - if adverse features, after DC shocks (x3), what next
Amiodarone 300mg IV over 10-20 mins
Repeat Shock
Then give Amiodarone 900mg over 24 hours
Tachycardia with pulse algorithm - if no adverse features, next step
assess QRS complex = broad or narrow
Tachycardia with pulse algorithm - if no adverse features, narrow tachycardia, next step (irregular)
Assess whether regular or irregular
If irregular = probable AF
Tx = 1) Control Rate with BB or Diltiazem
2) consider digoxin if HF
Tachycardia with pulse algorithm - if no adverse features, narrow tachycardia, next step (regular)
Assess whether regular or irregular
If regular
1) Vagal manoeuvres
2) Adenosine 6mg»_space; 12mg»_space; 12mg IV
what is half life of adenosine
8 to 10 seconds
Tachycardia with pulse algorithm - if no adverse features, broad complex tachycardia, next step (irregular)
Seek expert help
Tachycardia with pulse algorithm - if no adverse features, broad complex tachycardia, next step (regular)
IF VT
- Amiodarone 300mg IV over 20-60 mins then 900mg over 24 hours
ALS algorithm - first step
CPR 30:2
[assess rhythm]
ALS algorithm - what are the shockable rhythms
Pulseless VT
VF
ALS algorithm - next step with shockable rhythms
1 shock
ALS algortihm - how many shocks till [name drug] is given
after 3 shocks give adrenaline 1 mg IV and amiodarone 300 mg IV
give further Adrenaline with alternative shocks
ALS Algorithm - what are non-shockable rhythms
asystole
pulseless electrical activity
how often can adrenaline be given
every 3 to 5 minutes
what are the reversible causes
4H’s and 4T’s
Hypothermia
Hypoxia
Hypovalaemia
Hyperkalaemia/Hypokalaemia
Thrombosis
Toxin
Tension pneumothorax
Tamponade
ALS Algorithm - non-shockable rhythms, approach
1 - Start CPR 30:2
2 - Give Adrenaline as soon as access gained
3 - recheck rhythm after 2 mins
4 - Give further adrenaline 1 mg IV every 3–5 min (during alternate 2-min loops of CPR)
Paeds ALS Algorithm - step 1
5 rescue breaths
CPR 15:2
what is the dose of adrenaline for adults
500 micrograms IM [0.5 mL]
what is the dose of adrenaline for Child > 12 y/o
500 micrograms IM [0.5 mL]
what is the dose of adrenaline for Child 6 - 12 y/o
300 micrograms IM [0.3 mL]
what is the dose of adrenaline for Child < 6 y/o
150 micrograms IM [0.15mL]
what does it mean if adrenaline is 1 in 1000
1g in 1000ml
[as 1mg in 1ml]
i.e. to get 500 MICROgrams only need 0.5ml
doses of hydrocortisone for anaphylaxis = adult, child older than 12, child aged 6-12, child 6 months to 6 years, child < 6 months
adult and child older than 12 = 200mg
child aged 6-12 = 100mg
child aged 6 months to 6 years = 50mg
child < 6 months = 25mg
doses of chlorphenamine for anaphylaxis = adult, child older than 12, child aged 6-12, child 6 months to 6 years, child < 6 months
adult and child older than 12 = 10mg
child aged 6-12 = 5mg
child aged 6 months to 6 years = 2.5mg
child < 6 months = 250mcg
monitoring needed in anaphylaxis
ECG
Pulse oximetry
Blood Pressure
