Analgesia

One of the most important aspect in general anaesthesia is the loss of pain. During surgery, it is very difficult to find out wether the anesthesized patient feels pain and hence will develop cognitive impairement after surgery. Today, the anesthesiologist knows and detects physiological signs of pain, such as sweat, colour of skin or spontaneous unvoluntary movements. However, more objective criteria based on EEG may assist the pain detection and hence improves the patients' situation. To this end, we analyze large sets of patient EEG-data observed during surgery and aim to extract EEG signal features of pain.
