Raspberry-Pi based system for propofol monitoring

Sandro Carrara, Francesca Stradolini, Danilo Demarchi, Tugba Kilic, Abuduwaili Tuoheti

Induction of anesthesia with propofol is a largely adopted technique in hospital environments. The correct dosage of this compound is essential to avoid under- or over-anesthesia that may result in serious side-effects. Therefore, in clinical settings, lon ...

Energy metabolism in the rat cortex under thiopental anaesthesia measured

Rolf Gruetter, Nathalie Just, João Miguel das Neves Duarte, Sarah Catherine Sonnay

Barbiturates, commonly used as general anaesthetics, depress neuronal activity and thus cerebral metabolism. Moreover, they are likely to disrupt the metabolic support of astrocytes to neurons, as well as the uptake of nutrients from circulation. By employ ...

Towards 3D facial morphometry : facial image analysis applications in anesthesiology and 3D spectral nonrigid registration

Gabriel Louis Cuendet

In anesthesiology, the detection and anticipation of difficult tracheal intubation is crucial for patient safety. When undergoing general anesthesia, a patient who is unexpectedly difficult to intubate risks potential life-threatening complications with po ...

Cascaded PID controller for anaesthesia delivery

Monia Guidi, Alena Simalatsar

The technologies for continuous measurement of the anaesthetic agents circulating in body fluids are not mature yet, though some preliminary prototypes exist already. We present a control algorithm that based on the real measurement of propofol plasma conc ...

Size and Viewpoint of an Embodied Virtual Body Affect the Processing of Painful Stimuli

Olaf Blanke, Joan Llobera Mahy

Looking at one's own body might induce visual analgesia. However, the cognitive and physiological mechanisms underlying such visual analgesia are unknown. Because body and pain representations in the brain are multisensory, and have been reported to partia ...
