Detrended Fluctuation Analysis of EEG on a Depth of Anestheisa

Abstract

The DFA(detrended fluctuation analysis) which is included the correlation property of the EEG is used to analysis the depth of anesthesia. We studied ASA I or II adult patients supported by the society of anesthesiologists. Patients with history of dementia and neurological disorder are excluded. Average age is 48.9 ± 10.9 old, average weight is 57.1 ± 8.2 kg and average hight is 158 ± 6.6cm of the patients under the operation. Anesthesia medicine is Sevoflurane and the stages of anesthesia are 6 stages, that is pre-operation, induction, right after induction, stop the medicine and post-operation.Among the scaling exponent , , , we know that , were well appeared to discriminate pre-operation, induction, right after induction, stop the medicine and post-operation. So we confirmed that the parameters is useful to the depth of anesthesia. PU - The Korea Academia-Industrial cooperation Society
