There are many similarities exist between natural sleep and anesthesia. During early parts of natural sleep, an individual is difficult to arouse. During general anesthesia, a patient cannot be aroused. Parts of the brain that are responsible for sleep are similar to areas that control general anesthesia.When one type of anesthesia, propofol, is used and there is natural sleep debt, it dissipates. Specifically, a REM sleep deficit was apparent after exposure to isoflurane, sevoflurane or halothane and a NREM sleep deficit is seen after halothane In the United States, nearly 60,000 patients per day receive general anesthesia for surgery. General anesthesia is a drug-induced, reversible condition that includes specific behavioral and physiological traits unconsciousness, amnesia, analgesia, and akinesia with concomitant stability of the autonomic, cardiovascular, respiratory, and thermoregulatory systems. General anesthesia produces distinct patterns on the electroencephalogram (EEG), the most common of which is a progressive increase in low-frequency, high-amplitude activity as the level of general anesthesia deepens. Substantial insights can be gained by considering the relationship of general anesthesia to sleep and to coma.
