List some symptoms of LAST.

Explain the lipid rescue for LAST.
In addition to CPR -
1. bolus 20% intralipids 1.5ml/kg
2. start infusion at 0.25mg/kg/min
2. circulate lipids w/ CPR
3. repeat bolus q3-5 mins UP TO 3ml/kg total dose until ROSC.
4. ⬆ infusion to 0.5ml/kg/min if BP declines - continue infusion until hemodynamically stable.
*MAX DOSE: 8ml/kg
If you dont have 20% lipids immediately handy - give what you have until you obtain the 20%.
List the formula for Farenheit from Celcius.
°F = [(9/5) x °C) + 32]
If my patient’s temp is 96.8°F, what is it in °C?
94°F?
36°C
34.5°C
What is the formula for Celcius from Farenheit?
°C = [(5/9) x (°F - 32)]
If my patients temp is 38°C, what is it in °F?
40°C?
100.4 °F
104 °F
A nice pattern to help do quick temp conversions.
- If you start at 95°F - celcius is 35.
- As you increase in 0.9°F, each °C goes up by 0.5°
