If considers and whether or not it supplies the skin conductance signal which is measured in the territory of the skin of the patient over a certain time interval, it establishes the existence of two fluctuation peaks at least in the skin conductance signal in the aforementioned time interval, amplitude of fluctuation peak of the skin conductance signal in the aforementioned interval, fundamental level of the skin conductance signal which covers the aforementioned time interval, and width of fluctuation peak of the skin conductance signal, it satisfies the standard which is decided beforehand, the aforementioned standard is not filled up is filled up, the 1st output signal which shows the awakening state of the patient is operated the aforementioned standard, state of pain of the patient is shownMethod and the device in order to watch the patient who includes the step which operates the 2nd output signal, is quieted.< Selective figure >Figure 2患者の皮膚の領域において測定される皮膚コンダクタンス信号をある時間間隔にわたって供給し、前記時間間隔において、皮膚コンダクタンス信号に少なくとも2つの変動ピークの存在を確立し、前記間隔における皮膚コンダクタンス信号の変動ピークの振幅、前記時間間隔にわたる皮膚コンダクタンス信号の基礎レベル、及び皮膚コンダクタンス信号の変動ピークの幅が、予め決められた基準を満たすかどうかを考慮し、前記基準が満たされれば、患者の覚醒状態を示す第1の出力信号を作動させ、前記基準が満たされなければ、患者の痛みの状態を示す第2の出力信号を作動させるステップを含む、鎮静された患者を監視するための方法と装置。【選択図】図2
