Advanced LIVA/TIVA Techniques

چکیده
LIVA (Light Induced Voltage Alterations) and TIVA (Thermally Induced Voltage Alterations) have demonstrated significant capability for fault isolation. A difficulty with both techniques is their use of a constant current source, whereas integrated circuits operate with a constant voltage source. A new technique that utilizes the constant current sensing of LIVA/TIVA, while allowing for use of constant voltage bias on the integrated circuit, has been developed. As a bonus, the technique is also significantly more sensitive (at least one order of magnitude) than the standard LIVA/TIVA approach.

Total intravenous anaesthesia (TIVA) is defined as a technique of general anaesthesia using a combination of agents given solely by the intravenous route and in the absence of inhalational agents. This article reviews the indications, advantages and disadvantages, principle, mode of administration, clinical techniques and drugs used for TIVA. Total intravenous anesthesia, or TIVA, can provide a...
متن کاملThe effects of total intravenous anesthesia using propofol, ketamine, and vecuronium on cardiovascular response and wake up time.
Total intravenous anesthesia (TIVA) can be an effective alternative to inhalational anesthesia. Various techniques of TIVA have been associated with significant cardiovascular alterations and prolonged wake up times. The purpose of this study was to determine if TIVA utilizing propofol, ketamine, and vecuronium would provide stable hemodynamics in normotensive ASA physical status I and II patie...
