Arterial pressure control with isoflurane using fuzzy logic.
Arterial pressure is still one of the most important measures in estimating the required dose of inhaled anaesthetics. It is measured easily and reacts rapidly which makes it suitable as a variable for feedback control of depth of anaesthesia. Fuzzy logic, a novel approach to feedback control, was used to control arterial pressure in 10 patients during intraabdominal surgery by automatic adjust...
متن کاملRegulation of Arterial Pressure
Three anephric patients were studied during sequential periods of normal hydration and overhydration. The increase in arterial pressure caused by the overhydration (+ 7% of body weight) was associated with an increase in peripheral resistance (+ 21.1%, P < 0.01). The elevation of peripheral resistance was preceded by an increased cardiac output (+ 22.3%, P < 0.02) which then fell part way to co...
متن کاملA new closed-loop control system for isoflurane using bispectral index outperforms manual control.
BACKGROUND Automatic control of depth of hypnosis using the Bispectral Index (BIS) can help to reduce phases of inadequate control. Automated BIS control with propofol or isoflurane administration via an infusion system has recently been described, a comparable study with isoflurane administration via a vaporizer had not been conducted yet. Our hypothesis was that our new model based closed-loo...
متن کاملComponents of the inspiratory-arterial isoflurane partial pressure difference.
We have measured the partial pressure of isoflurane simultaneously in inspired gas (PIiso), end-expired gas (PE'iso), mixed-expired gas (PEiso), arterial (Paiso) and mixed venous blood (Pviso) in six patients (aged 57-79 yr) anaesthetized with nitrous oxide, oxygen and isoflurane before surgery and after PE'iso had been stable for at least 15 min. We related these changes to the various indices...
متن کاملa comparison of effects of propofol and isoflurane on arterial oxygenation pressure, mean arterial pressure and heart rate variations following one-lung ventilation in thoracic surgeries
conclusions: the effects of propofol on hemodynamics and arterial oxygen pressure during one- or two-lung ventilation were not different from those of isoflurane. results: sixty patients (mean age = 4124.18 ± 18.63 years) were divided into two groups. the age and gender of the subjects were not statistically different between the two groups. in the propofol group, the arterial oxygen pressure d...
