Randomized Controlled Trial Comparative Study
Differences between state entropy and bispectral index during analysis of identical electroencephalogram signals: A randomised comparison of two anaesthetic techniques.
It is claimed that bispectral index (BIS) and state entropy reflect an identical clinical spectrum, the hypnotic component of anaesthesia. So far, it is not known to what extent different devices display similar index values while processing identical electroencephalogram (EEG) signals. ⋯ High-frequency signals and eye blinks may account for index values that falsely indicate consciousness. Compared with BIS, state entropy showed more false classifications of the clinical state at transition between consciousness and unconsciousness.

Observational Study
Effect of ramosetron on the QT interval during sevoflurane anaesthesia in children: A prospective observational study.
We investigated the effects of concomitant administration of sevoflurane and ramosetron on the QT interval, the interval between the peak and end of the T wave (Tpe) and Tpe/QT ratio in children. ⋯ Ramosetron was not associated with prolongation of the QTc interval when it was given concomitantly with sevoflurane in children. No ventricular arrhythmias or other adverse effects occurred during the study.
