Processed EEG in anaesthesia
Overview of using Processed EEG in anaesthesia covering:
0:00 Introduction
0:55 Raw EEG Basics
3:55 EEG changes with induction
5:55 Power Spectrum
7:30 SEF/MEF (and why I don't like it!)
11:30 BIS Index values and their calibration
16:04 NOT monitors of consciousness!
17:49 BIS index DO NOT correlate with the EEG morphology
18:38 Narcotrend indices DO correlate with EEG (Kugler's taxonomy)
21:08 pEEG is about more than just numbers!
22:45 Schuller Study - awake, paralysed with low BIS index
24:20 Spectrograms and Density Spectral Array (DSA) basics
26:58 Effects of different drugs on the EEG and DSA
29:35 Comparison of DSA on different devices, and device comparison
34:15 VIDEO: EEG changes during Rapid Sequence Induction (RSI) [Bottom Up PkPd]
36:10 VIDEO: EEG changes with slow induction [Top Down PkPd]
38:48 Top down vs Bottom up pharmacodynamic summary
39:38 Effects of ketamine on the EEG
41:28 VIDEO: EEG changes following a small ketamine bolus
42:30 VIDEO: EEG changes following a large ketamine bolus for RSI
44:20 CASE: Ketamine induction and maintenance DSA
46:28 Using EEG to explore anaesthetic mechanisms - sensory disconnection
49:35 Anti-nociception - defending Castle Thalamus from the dark knights of nociception
50:38 VIDEO: Cortical arousal during rapid sequence induction with thiopental
52:26 CASE: Good antinociception & personalised anaesthesia in aging brain
53:50 Types of EEG arousal - beta, alpha drop out and paradoxical delta
54:45 Effects of brain aging on the EEG and DSA
56:00 Not all indices are created equal...
57:45 Burst suppression and brain metabolism
59:00 Some monitors are poorly coupled to suppression (BIS, Entropy)
1:01:09 Non anaesthetic causes of suppression
1:02:10 CASE: Suppression secondary to anaphylaxis
