Monitoring the EEG in the Operating Room

The EEG was the first electronic monitor to be used in the operating room. It has undergone periods of enthusiasm and disillusionment during its nearly 4o-year career. There are several reasons for the problems and the lack of enthusiasm which the EEG has encountered 1. First, unlike the ECG, it is a difficult wave form to interpret unless one has had considerable training. Although some EEG patterns are easy to interpret, such as enflurane seizures, most are not for the average neurological layman. Another problem involves the way the EEG is conventionally displayed - either on a fairly rapidly moving strip chart or on an oscilloscope screen. With the former, a permanent record is achieved, but at the cost of a very large amount of paper - generated at a rate of 3oo pages an hour. It is extremely difficult to shuffle through these pages and compare what is happening presently to the patient with what happened during induction or three hours ago, for example. An oscilloscope is no better. Although it does not waste paper, it only provides a fleeting display, which must be remembered and compared with previous patterns in one’s own mind.
