Waking up during surgery: Low-cost prevention?

06.04.2009
Michael Avidan, George Mashour and David Glick highlight the serious issue of awareness during anaesthesia in a recent review published by F1000 Medicine Reports.

Consciousness during general anaesthesia is an extremely distressing condition leading to post-operative psychological trauma and contributes towards patients' fear of surgery. Dr Avidan, a member of Faculty of 1000 Medicine and a leading authority on Anaesthesia and Pain Management, writes that intra-operative awareness with subsequent recall is surprisingly common, affecting around 1 in 500 surgical cases. These appear to be mostly preventable.

There are currently a number of candidate awareness monitors available to anaesthesiologists and theatre staff, but attention has focussed on the bispectral index (BIS) monitor, which is used widely in operating rooms and intensive care units around the world. However, it is not clear that the reduction in awareness reported with BIS monitors is attributable predominantly to the technology itself. Controversially, recent research suggests that previous cases of awareness with explicit recall might have been prevented by implementing a simple 'increased vigilance' protocol. Such a protocol would cost less and be less prone to machine malfunction.

Large, prospective randomized trials are currently underway to evaluate effective awareness monitoring technologies, with the aim of ultimately improving intra-operative patient care. Avidan says, "Cost effective interventions that increase vigilance should be implemented to decrease the likelihood of this complication."

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
