Anaesthesia – can the patient feel the knife?


Anaesthetic agents are potentially dangerous drugs, and major patient complications can occur. If the patient is overdosed, death or major body organ damage can occur. Conversely, if the patient is under-dosed, patient awareness can occur. There is a narrow drug concentration “window” for both drug safety and anaesthetic efficacy, and the development of ways in which to monitor drug delivery concentration has been a major driver in anaesthetic agent safety research.

The Oxford invention has met this anaesthesia challenge by using modified statistical techniques to classify the physiological state of a human or animal subject. The classification monitors changes in the physiological state that occur over time either spontaneously or from external stimuli. Analysis of data obtained from anaesthetic trials has demonstrated the efficacy of the method for monitoring the depth of anaesthesia.

As well as using encephalograms the invention may be used advantageously with other forms of physiological data: electromyography to indicate muscle activity; analysis of images from magnetic resonance, computed tomography, X-ray and ultrasound; electrocardiography for blood pressure and blood oxygenation. The method also has many other applications including the monitoring of: consciousness, sleep, neuropathology, cerebral intoxication, cognitive state and muscle tremor.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
