THE VALUE OF BISPECTRAL INDEX MONITORING IN SHORTENING RECOVERY TIME IN ENDOSCOPIC NEUROSURGICAL PROCEDURES

Abstract

BIS index is an FDA approved monitor for assessing the sleep/awake status for patients, BIS monitor is a non-invasive device that is easily applied to the forehead, it can be applied in all ages, sex, various medical and surgical situations. The use of BIS guided anesthesia can aid in adjusting anesthetic agents required for induction of anesthesia that is sufficient to blunt the stress response accompanying larygoscopy and intubation, maintenance and recovery of anesthesia. BIS benefits can be extended far beyond OR and can be used in the ICU to help in providing sedation and analgesia. Neuroendoscopic surgery is a complex procedure that requires intense monitoring of the hemodynamic status, for decades, anesthesia delivery in such setting was guided by hemodynamics, however several reports had proven that such concept is untrue, moreover such concept can have serious consequences, as hemodynamic status not essentially reflect the anesthetic status. The development of new drugs, that have short duration had made such concept much easier than the past, however the sole rely on such drugs alone cannot either guarantee an adequate anesthesia status or fast track anesthesia, the use of BIS monitor together with routine hemodynamic monitoring and clinical signs can represent an addition to neuroendoscopic surgeries .
