New survey reports low rate of patient awareness during anesthesia

12.03.2013
The Royal College of Anaesthetists (RCoA) and the Association of Anaesthetists of Great Britain and Ireland (AAGBI) today publish initial findings from a major study which looked at how many patients experienced accidental awareness during general anaesthesia.

The survey asked all senior anaesthetists in NHS hospitals in the UK (more than 80% of whom replied) to report how many cases of accidental awareness during general anaesthesia they encountered in 2011. There are three million general anaesthetics administered each year. Study findings are published in Anaesthesia, and The British Journal of Anaesthesia, the peer-reviewed journals of the AAGBI, and RCoA respectively.

Previous reports have suggested a surprisingly high incidence of awareness of about one in 500 general anaesthetics. The current report found it to be much less common in the UK with one episode known to anaesthetists in every 15,000 general anaesthetics. The report also reports very low use of brain monitoring technology: with only 2% of anaesthetists routinely using it.

The survey is part of a major study called the Fifth National Audit Project (NAP5) taking place over three years. NAP5 is thought to be the largest study of its kind ever conducted and is funded entirely by the profession.

Professor Jaideep Pandit, Consultant Anaesthetist in Oxford and lead author, said, "Anaesthesia is a medical speciality very much focussed on safety and patient experience. We identified accidental awareness during anaesthesia as something which concerns patients and the profession. The profession is therefore undertaking this major study so that we can better understand the problem and work to reduce the likelihood of it happening to patients."

"We are particularly interested in patient experiences of awareness. Although we know that some patients do suffer distress after these episodes, our survey has found that the vast majority of episodes are brief and do not cause pain or distress."

"Our study will continue to explore the reasons for the differences between our figures and previous reports. Anaesthesia in the UK is administered only by trained doctors and is a consultant-led service. Whether this – or other factors such as differences in patient sensitivity to anaesthetic drugs or different detection rates influence the reported numbers – is something we will be studying in the rest of the project."

Professor Tim Cook, co-author and a Consultant Anaesthetist in Bath said, "Risks to patients undergoing general anaesthesia are very small and have decreased considerably in the last decades. Anaesthesia doctors in the UK undergo the same level of training as surgeons and physicians. Of the three million general anaesthetics administered in the NHS each year, only a very small number of patients experience awareness during anaesthesia, with the majority of these occurring before surgery starts or after it finishes."

"While our findings are generally reassuring for patients and doctors alike, we recognize that there is still more work to be done. We are spending the next year studying as many of the cases as possible to learn more from patients' experiences. It is hoped that the findings included in the final report, due out early 2014, will increase our understanding of accidental awareness during general anaesthesia so that the anaesthetic profession can further increase safety for patients."

"Anaesthetists have always put patients first and will continue to do so. This study, which comes just after the publication of the Francis report, shows that anaesthetists are clearly listening to patients and have acted positively to address a major patient concern."

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
