Wintergreen Research
Market Study  December 2003

There are 40 million surgical interventions performed annually in the U.S. under general anesthesia. The number of surgical and anesthesia-based interventions both therapeutic and diagnostic is expected to increase as the population ages. There is more than double that number worldwide.

EEG processors are poised to be useful in every one of those interventions. Units are positioned to save lives by providing one more way to monitor patient condition.

EEG monitoring is of value to the anesthesiologist because it provides direct measurement of brain activity and provides input that cannot be achieved from heart or oxygen saturation level monitoring.

A simple automated EEG implemented as a processor monitor permits use and brain wave interpretation in the operating room. Resolution of presentation of information is an essential aspect of systems. Monitoring a patient brain activity during surgery improves patient safety and lowers costs per surgical procedure. Controlling the amount of anesthesia administered during surgeries is a measurable benefit. It reduces the amount of postoperative recovery time required.

The electrophysiology of the brain is a center of research. Changes in brain electrophysiologic activity occur during general anesthesia. The EEG seems to provide a direct indication of the patient depth of consciousness as invoked by anesthetic agents. The EEG is the most reliable indicator of excessive administration of anesthesia.

The EEG processor medical device industry competition is limited to two major companies. Aspect Medical Systems and Physiometrix are the two companies with working technology for anesthesia. Devices are based on signal processing of the EEG brain waves. Additional competition may come from patient monitoring companies; currently marketing conventional EEG monitors utilizing standard signal-processing techniques such as spectral edge frequency analyses and median frequency analyses.

Total worldwide markets for EEG processor and sensors for both surgical and intensive care markets at $51.4 million in 2002 are expected to reach $734.9 by 2008.
