1
Q
What is the best method of assessing a deep neuromuscular block
A
Post-tetanic count
2
Q
How is train-of-four assessed
A
By comparing the height of 4th twitch to the height of 1st
3
Q
What is a TOF ratio of 1.0
When is TOF 1.0
A
T4 = T1
This occurs when there is no neuromuscular blockade
4
Q
What is a TOF ratio of 0.5
A
T4 < T1 by 50%
5
Q
What is the definition of fade and what causes this
A
When T4/T1 ratio is <1.0
Causes = nondepolarizing NMB or phase 2 block w/ depolarizer NMB
6
Q
What TOF ratio is neuromuscular blocker recovery
A
TOF > 0.9
