Entropy
associated with low probability of consciousness. A decrease in Entropy may enable
the physician to observe the moment when the patient loses responsiveness. During
continued anesthesia, both Entropies stabilize.
During general anesthesia with adequate anesthesia and hypnosis the RE and SE
values will be within a narrow range or equal. The numbers will also merge during
profound neuromuscular paralysis with neuromuscular blocking agents since the
patient’s facial muscles are unable to react.
RE is typically higher during periods prior to induction and before wake-up. If the
numbers diverge (RE exceeds SE) during general anesthesia, it indicates that the facial
muscles are activated. This may happen due to noxious stimuli. SE value may remain
within a constant range if the level of hypnosis is adequate. A quick rise in RE may give
an early warning of impending wake-up.
Patients emerging from general anesthesia will demonstrate a rise in both the RE
and SE values.
