Performance assessment of a fuzzy controller for atracurium-induced neuromuscular block.

abstract：BACKGROUND:State entropy (SE) is a newly available monitor for depth of anaesthesia. We investigated whether the relationship between predicted effect-site propofol concentration and Bispectral Index (BIS) and SE values is useful for predicting loss of verbal contact and loss of consciousness during steady-state condit...
