Anesthesia is full of claims. We define a claim as practice decision that we either believe true or something default to. Oftentimes claims are rooted in anecdotal clinical experiences observations derived from basic science. Such then introduced into without further rigorous examination. These often given life and perpetuated to trainees.

A new approach to estimating level of unconsciousness based on Principal Component Analysis (PCA) is proposed. The Electroencephalogram (EEG) data was captured in both Intensive Care Unit (ICU) and operating room, using different anesthetic drugs. Assuming the central nervous system as a 20-tuple source, window length of 20 seconds is applied to EEG. The mentioned window is considered as 20 non...

The EEG is a valuable tool because it reflects cerebral physiology, it is a continuous and non-invasive measure, and it changes markedly on the administration of anesthetic drugs. The objective of this project is to find the excellent features to discriminate between different anesthesia states. Spectral Edge Frequency (SEF), spectral entropy and bicoherence can be used to differentiate differe...

The author discusses state-of-the-art technology for patient monitoring in office-based anesthesia. New technology includes bispectral index monitoring to evaluate the depth of anesthesia, signal extraction for more accurate oxygen saturation monitoring, and online S-T segment analysis for monitoring multiple electrocardiographic leads.

BACKGROUND The auditory evoked potential (AEP) index, which is a single numerical parameter derived from the AEP in real time and which describes the underlying morphology of the AEP, has been studied as a monitor of anesthetic depth. The current study was designed to evaluate the accuracy of AEPindex for predicting depth of sedation and anesthesia during sevoflurane anesthesia. METHODS In th...

ARCOTREND index (NI) is based on studies of normal human brain electrical data. It uses an ordinary electrode to collect and analysis brain electrical signals immediately at any position of the head, to display the state of consciousness and depth of anesthesia of patients on the touch screen after automatic analysis and classification, so as to guide dose adjustment of anesthetics. NI may make...

introduction: failure to achieve adequate and profound anesthesia in teeth with acute pulp inflammation is a common condition during emergency visits in root canal therapy. many different anesthetic solutions such as morphine and capsaicin have accordingly been examined. mannitol­ an alcoholic sugar with high osmotic pressure level- is applicated for reducing intracranial and post retinal press...
