Consciousness, EEG and depth of anaesthesia monitoring

By Peng Wen


Many surgical procedures would not be possible without patient entering a state of unconsciousness. The essential features of a successful general anaesthesia, displayed by the patient, are a reversible loss of consciousness (LOC) with a lack of movement, a lack of awareness, unresponsiveness to painful stimuli and a lack of recall of the surgical intervention. Inadequate general anaesthesia may lead to intraoperative awareness with recall or to prolonged recovery and an increased risk of postoperative complications for the patient. An important contributing factor to inadequate general anaesthesia is our current limited ability to assess the levels of consciousness
