background: awareness and recall, though not common, are the major hazards of general anesthesia, especially in cesarean section (c/s) because of the absence of benzodiazepine and opioids for a significant time during anesthesia. in this study, the bispectral index (bis), end-tidal isoflurane, and hemodynamic parameters were examined to evaluate the depth of the routine general anesthetic techn...

BACKGROUND The importance of proper qualitative evaluation of EEG parameters during surgery has been recognized since many years. Although none of the characteristics based on the frequency, entropy, and Bi spectral characteristics have been regarded as a good predictor for detection of the depth of anesthesia alone. So it seems necessary to study multiple characteristics together. OBJECTIVES...

In the clinical practice the concerns about the administration of hypnotics and analgesics for minimally invasive diagnostics and therapeutic procedures have enormously increased in recent years. The automatic detection of changes in the signals used to evaluate the depth of anesthesia is hence of foremost importance in order to decide how to adapt administered doses to patients undergoing surg...

The heart is the most important of the vital organs and heart diseases may cause fatal consequences. Abnormal heart sounds called murmur may be a precursor of many serious heart diseases. Cardiac auscultation is a basic technique to easily diagnose murmur disease. Auscultation can be supported by using computer aided automatic diagnosis systems to fast and accurate diagnosis. These systems are ...

Determining depth of anesthesia is a challenging problem in the context of biomedical signal processing. Various methods have been suggested to determine a quantitative index as depth of anesthesia, but most of these methods suffer from high sensitivity during the surgery. A novel method based on energy scattering of samples in the wavelet domain is suggested to represent the basic content of e...

T he term anesthesia originally meant " the state in which a patient is insensible to the trauma of surgery. " Although, the science of anesthesiol-ogy has advanced rapidly, defining, measuring, and understanding depth of anesthesia has moved ahead slowly. Indeed, we are yet to define properly the phenomenon that we use in our everyday practice to render patients insensitive to the trauma of su...
