things
Local Anesthesia what is the order of what is lost first - ANSWER✔✔-ATP PT MVP Motor
Autonomic, Temperature, Pain, Pressure, Touch, Motion, Vibration, Proprioception, Motor
B > C > small A (delta) > Large A (alpha) - ANSWER✔✔-LA Nerves (order)
· Lidocaine: 10-20 min (onset), 2-3 hrs (duration)
· Ropivacaine: 10-30 min (onset), 2-8 hrs (duration)

, Spinal: motor +2 dermatomes above = sensory block, +2-6 above sensory = ANS block
Epidural: motor +2-6 above = sensory & ANS block - ANSWER✔✔-Spinal anesthesia dermatomes
vs epidural anesthesia dermatomes (motor, sensory, ANS)
1. Hypotension
2. Transient metabolic acidosis
3. ↑ CO2 levels - ANSWER✔✔-What 3 things happen when you deflate a tourniquet?
100 μAmp = micro shock
1 mAmp = perception threshold
15 mAmp = let-go current
200 mAmp = V-Fib
*(A current of 1 Amp is significantly larger than 100 microamps (μA); 1 Amp is equivalent to 1000
times more current than 100 μA, as "micro" means one millionth, so 100 μA is just 0.0001 Amps) -
ANSWER✔✔-Electrical current matching: mirco shock, V fibrillation, let-go current, perception
threshold
