Life support Flashcards
If patients temp <30 degrees and in arrest/arrythmia/SBP <90 what should we do?
Transfer to ECMO centre
If temp <30 degrees what change should we make to the ALS algorithm? (2)
- Don’t give adrenaline
2 If 3 shocks unsuccessful don’t shock again until >30 degrees
When temp is 30-34 degrees what should we do with adrenaline?
Increase interval to 6-10min
How should heat syncope be managed?
Cool and oral fluids
How should heat exhaustion be managed? (3)
- Cool enviroment
- Lie flat
- IV isotonic/hypertonic fluid
How should we manage heat stroke? (4)
- Actively cool
- IVI - hypertonic if Na+ <130 (up to 3 x 100ml 3% saline)
- Benzos if seizing but will also help with cooling, no anti-pyretics
- Aim temp 38.5, not normothermia
- May need RRT/I+V/peritoneal or chest lavage
May need IVI ++
What is the treatment for malignant hyperthermia? (4)
- Stop triggering agent
- Target normocapnia
- Active cooling
- Dantrolene
How long should patients be observed following malignant hyperthermia?
72 hours - 25% relapse
How long should we perform CPR if we thrombolyse PE?
60-90 mins
What dose ALSG state is managment of tension PTX in arrest?
Thoracostomy
Can use needle decompression if quicker but needs to be followed up by thoracostomy and chest drain
What is the difference between laryngectomy and tracheostomy in relations to resus?
Laryngectomy patients do not have a patent airway and therefore oral measures will not work at all
If suspecting an issue with a tracheostomy what is the very first step to assess?
Look/listen/feel mouth and trachy
ETC02 and Mapleson C can help
If you have assessed a trachy and suspect an occlusion what is the first step in the algorithm following the initial look/listen/feel?
Remove any speaking valve or cap and inner tubs and place a suction catheter down
If is passes then it is at least partially patent
If you have removed a tracheostomy inner tube but cannot pass a suction catheter down if, what is the next step in the algorithm?
Deflate the cuff
If improves then either partial tube obstruction or diplaced
You have removed the inner tube of a trachy and deflated it with no effect. What is the next step?
Remove trachy tube
What are the primary emergency oxygenation maneuvers once a tracheostomy has been removed because it wasn’t working? (2)
- Standard oral oxygenation measure (facemask/adjuncts)
- Tracheostomy stoma ventilation (paeds face mask/LMA to stoma)
What are the secondary emergency oxygenation measures once a tracheostomy has been removed? (2)
- Oral intubation (uncut tube and advance beyond stoma)
- Stoma intubation - small trachy tube/size 6 ETT cuffed, consider fibre-optic or bougie
What are the 5 types of heat illness?
What are the 3 cardinal signs of heat stroke?
- Temp >40 degrees
- Encephalopathy
- Anhydrosis
What is the underlying mechanism that makes heat stroke different from heat exhuastion?
SIRS response leading to multi-organ failure with encephalopathy predominating
What biochemical abnormalities can be seen in heat stroke? (6)
What are the two types of decompression injury?
Decompression sickness - evolved gas being release
Arterial gas embolism (AGE) - escaped gas bubble in arterial system (either via PFO for overwhelming the lungs).
In neonatal resus what are the fist steps to take when the baby is born? (4)
- Delay cord clamping if possible
- Start clock
- Wrap + stimulate
- Head neutral
If a baby has been stimulate and is not breathing what is the next steps (3)
- 5 inflation breaths (30cmH20)
- 5-6cmH20 PEEP
- Oximetry +/- ECG
Following 5 inflations breaths the baby is still not breathing - what are the next steps? (5)
- Check position
- 2 person technique
- Suction
- Repeat 5 inflation breaths
- Consider increasing pressure
You have delivered 5 inflation breaths to a neonate and the chest is now moving - now what?
30 secs ventilation breaths
Following 30 secs ventilation breaths there is no pulse or HR <60bpm - what are your next steps? (5)
- 3:1 breaths:compressions
- 100% Fi02
- I+V 3mm ETT
- Reassess every 30 seconds
- IV access and drugs
With regards to neonatal resusitation what should be done if a baby is < 32 weeks in terms of heating?
- Place undried in plastic wrap
- Under radiant heat
What Fi02 should be used in the first stages of neonatal resus based on gestational age? (3)
- > 32 weeks - 21%
- 28-31 weeks 21-30%
- < 28 weeks 30%
What are appropriate pre-ductal SATs (right hand) in terms of term after birth (3)
- 2 mins = 65%
- 5 mins = 85%
- 10mins = 90%
What should we aim to do with cord clamping in neonatal resus? (3)
- Aim to delay at least 60 secs until after lungs aerated
- If practical can keep unclamped
- If < 28/40 ‘cord milking’ - milk mothers blood to baby
When should drugs be used in neonatal resus?
If no CO despite good ventilation and chest compressions
What dose of adrenaline should be used in neonatal resus? (2)
10mcg/kg (0.1mk/kg 1 in 10,000)
No response consider increasing to 30 mcg/kg
When should sodium bicarbonate be used in neonatal resus and what dose?
- No CO and low HR
- 1-2mmol/kg (2-4ml 4.2 bicarbonate)
What dose of atropine and calcium should be used in neonatal resus?
No role in neonatal resus
When should stopping neonatal resusitation be considered?
After 20 mins if all reversible causes have been considered
What ratio compressions should be used in paeds resus?
15:2
What size BVM should be used in paeds resus?
< 1 year = 500ml bag
> 1 year = 1600ml bag
What long should IV access take place for before switching to IO?
2 attempts or 90 secs then IO
What is the dose of atropine in paeds resus?
20mcg/kg (minumum 100mcg)
What is the dose of amioderone in paeds resus?
5mg/kg
What is the dose of lidocaine (can be used instead of amioderone) in paeds resus?
1mg/kg
