Intubation may induce electromyographic (EMG) activity, causing depth of anaesthesia monitors to show misleadingly high values. The investigators want to investigate whether this EMG activity can be visually seen on the anaesthesia monitor.
Patients are anaesthetized with target controlled infusion of propofol. To facilitate intubation, the patients are randomized to receive rocuronium either 0,6 mg/kg or 1,2 mg/kg. BIS, Entropy and the biosignal collected with the Entropy strip are collected on a computer. The visible biosignal on the anaesthesia monitor is recorded with a video camera. BIS, Entropy, biosignal and video clip of the anaesthesia monitor will be analyzed in detail.
