NORWOOD, Mass.–(EMWNews)–Aspect Medical Systems (NASDAQ: ASPM), the global market leader in brain
monitoring technology, today announced that the Company’s
letter to the editor regarding a study and editorial evaluating use of
BIS® technology to reduce the risk of
anesthesia awareness was published in the July 24th issue of the New
England Journal of Medicine (NEJM). The NEJM also
published letters from Dr. Paul Myles and co-investigators from the
Australian B-Aware trial published in The Lancet in 2004, Dr.
Lulong Bo and colleagues from Changhai Hospital in China, Dr. Diamanto
Aretha and colleagues from University Hospital of Patras in Greece, and
Dr. Tim M. Cook, from Royal United Hospital in Bath, United Kingdom.
Responses from Dr. Michael Avidan and colleagues, authors of the NEJM
study, and Dr. Beverly A. Orser, author of the NEJM editorial,
were also published. A link to view this correspondence is available at www.aspectmedical.com.
“The awareness study recently published in the New
England Journal of Medicine has prompted significant discussion
throughout the global anesthesia community concerning the role of brain
monitoring and the issues associated with too little as well as too much
anesthesia,” said Scott Kelley, M.D.,
anesthesiologist and vice president and medical director of Aspect
Medical Systems. “We are pleased that many
leading anesthesia researchers and thought leaders have expressed the
need to consider a variety of outcomes, including avoiding awareness, in
managing a patient’s anesthesia care.”
A recent editorial published in the British Journal of Anaesthesia
(BJA) following the 7th International
Symposium on Memory and Awareness, provided a current assessment of
clinical strategies to avoid awareness, including the role of depth of
anesthesia monitoring. Notably, in commenting upon the NEJM
study, the BJA editorial emphasized that the end-tidal anesthetic
gas protocol used in the NEJM study is not reflective of current
standard practice, but in fact is an alternate practice change that
might be considered by clinicians. A link to this editorial is available
“The BJA editorial also highlights the
emerging concerns related to anesthesia exposure and states that the NEJM
study results support the need to ‘modify
contemporary practice’ with one of the
approaches shown to reduce risk of awareness,”
said Dr. Kelley. “Avoiding awareness is just
one of many goals that anesthesia professionals seek and, given the
extensive clinical evidence and our experience in monitoring more than
27 million patients worldwide, we believe that use of brain monitoring
to help guide anesthetic titration while maintaining a BIS value of less
than 60 is a very effective way to individualize care, minimize
awareness and improve patient outcomes.”

Cautionary Statement Concerning Forward-Looking Information
Certain statements in this press release are forward-looking within
the meaning of the Private Securities Litigation Reform Act of 1995 and
may involve risks and uncertainties, including statements about the
potential benefits of the Company’s brain
monitoring technologies in helping anesthesia providers deliver
anesthesia and in reducing the incidence of awareness and statements
regarding the use and adoption of BIS monitoring technologies. There are
a number of important factors that could cause actual results to differ
materially from those indicated by these forward-looking statements. For
example, future clinical trials and clinician use could demonstrate
different and/or unfavorable results regarding the potential benefits of
the Company’s brain monitoring product. The
Company may also not be able to achieve widespread market acceptance of
its BIS monitoring technology, or to compete with new products or
alternative techniques that may be developed by others, including
third-party anesthesia monitoring products approved by the FDA. Cases of
awareness with recall during monitoring with the BIS system and
significant product liability claims are among the factors that could
limit market acceptance. The Company also faces competitive and
regulatory risks relating to its ability to successfully develop and
introduce enhancements and new products including the BIS VISTA monitor
and products based upon its neuroscience technology. There are other
factors that could cause the Company’s actual results to vary from its
forward-looking statements, including without limitation those set forth
under the heading “Risk Factors” in the Company’s Quarterly Report on
Form 10-Q for the fiscal quarter ended March 29, 2008 as filed with the
