Extracted from text ... Southern African Journal of Anaesthesia & Analgesia ? March 2006 25 REGISTRAR The relationship between intra-operative entropy of the EEG and non-depolarizing neuromuscular blockade: A descriptive study HW van Rooyen Background Entropy is based on the extent of order in both the cortical EEG and facial EMG (FEMG) signals, measured from the patient's forehead. Order equals regularity of the EEG signal. In an awake patient, the EEG is very irregular and the entropy high. As the level of anesthesia deepens, the EEG becomes more orderly and the entropy reduces.1 The deeper the level of anesthesia, the lower the frequency ..
