ReviewElectrophysiological monitoring in the intensive care unit.
Spontaneous electrical activity (EEG) and event-related computer averaged brain electrical potentials (EPs) are becoming an integral part of CNS function monitoring in neurological intensive care patients. EEG monitoring using the compressed spectral array (CSA) computer analysis offers continuous information about cerebral electrical activity, permitting an accurate definition of the severity of brain injury, forecasting patient's course, and early detection of secondary intracranial changes. It offers more precise indications for treatment and prognosis. ⋯ Changes is electrophysiological patterns are often related to changes in other physiological parameters or events affecting the patient. Consequently, it appears advantageous to monitor simultaneously other CNS and body functions and record, process and display the data obtained in the patient care area. To make this comprehensive monitoring system reliable and useful, a wise application of advanced computer technology and a high degree of understanding of intracranial dynamics are required.

ReviewSleep/wake disturbances in working life.
This paper reviews the effects of shift work on sleep, alertness and well-being. It is seen that shift work causes disturbed sleep and increased fatigue. ⋯ Similarly, wakefulness is displaced to the circadian trough where the sleep-promoting properties of the circadian rhythm are at their maximum. The review concludes with a discussion of possible countermeasures.

Electrical stimulation of the nervous system for pain control.
Transcutaneous electrical stimulation appears to be a valid technique for the treatment of many pain states. Its use in chronic pain is limited and it appears to be much more likely to be effective in the relief of acute painful states. Nevertheless, since it provides a simple way to treat a significant number of patients whose pain would otherwise by intractable, it has been a valuable addition to the armamentarium of the physician dealing with chronic pain. ⋯ Spinal cord stimulation could act through a retrograde effect upon a dorsal horn gate or have more central actions. Brain stimulation in the opiate receptor system may be effective through activation of this system. The mechanisms of action of stimulation in the sensory system centrally are certainly not well understood (Bloedel 1974).
