American Society of Anesthesiologissts: Upcoming Conference & Abstracts on Neuromonitoring

Tha annual meeting of American Association of Anesthesiologist will be held during
October 13-17, 2007 San Francisco, CA. There are several interesting research and clinical studies on using neuromonitoring, how different anesthesia affects the intraoperative recording. You can click this highligted assn "Amer Assoc Anesthesiologist Meeting" and read all the important abstracts.
Here is a sample abstrat:

Somatosensory and Motor Evoked Potentials during Sevoflurane and Propofol Anesthesia

Michael S. Kincaid, M.D., Michael J. Souter, M.D., Patrick D. Bryan, Mark Klein, Arthur M. Lam, M.D.Anesthesiology, University of Washington, Seattle, Washington

Background and Purpose: Transcranial electrical motor evoked potentials (MEP) have joined somatosensory evoked potentials (SSEP) as an important aspect of neurophysiologic monitoring during both intracranial and spine surgery. General anesthesia is known to diminish the quality of signals with SSEP, decreasing amplitude and increasing latency, with volatile anesthesia having a greater effect than intravenous anesthesia. There is little quantitative information on the comparative effect of volatile and intravenous anesthetics on MEP signal quality, however. The purpose of this study is to describe the effects of propofol and sevoflurane on SSEP and MEP in patients undergoing both spine and neurosurgical procedures.

This article has no abstract so we have provided the first paragraph of the full text.

The avoidance of iatrogenic neurological injury is of paramount importance during spinal surgery, and multimodality intraoperative monitoring using a combination of MEPs, SSEPs and electromyographic (EMG) signals is increasingly used in this setting.1, 2 During corrective procedures for neuromuscular scoliosis, however, the successful application of intraoperative monitoring is a challenge
, particularly in the most severely deformed and neurologically compromised patients.3 Difficulties in obtaining reliable baseline recordings of conventional (cortical and subcortical) SSEPs and transcranial MEPs in patients with neuromuscular scoliosis has prompted the use of an epidural electrode to record spinal SSEPs and evoke neurogenic MEPs.
