a study on intra operative alertness is currently underway in munich. patient nina have now is being prepared for knee surgery. this cap measures. brainwaves even more precisely than the standard 3 electrodes on the forehead. the researchers have developed a method for communicating with the patient in case she wakes up during surgery. that is to say it s a blood pressure cuff keeps the muscle relaxing medication from getting into her forearm. this ensures that if the patient is conscious while under anesthesia she can move her hand.
a higher dose of painkillers than we initially thought but he does think that this has to do with pain pills section varying between people so it s hard to previous s. it. seems. every person s perception of pain is different researchers make use of this in their search for alternatives to general anesthesia. for example and you know. there is fresh. clean air. coming in through the window. hypnosis instead of anesthesia and sounds a bit like a joke. but neurosurgeon. is building on a long tradition. during the early days of surgery practically every operation was performed with the use of hypnosis. but with the development of
a. gnosis has many advantages patients are less scared their blood circulation is more stable bleeding happens less often less pain medication gets used and patients who are hypnotised stay in hospitals for less time than those who received general anesthesia. medicine has made huge leaps forward and only one in 136000 operations has a patient died from the effects of anesthesia. going under anesthesia 30 years ago was very different to our it is today in terms of tolerance effectiveness maintenance side effects. but there s still room for improvement using e.g. to monitor anaesthesia depth is not yet standard everywhere. i still don t understand why anesthesiologist measure everything blood pressure heart rate saturation but the brain where things are happening isn t monitored. basic research
will continue developing and perhaps someday lift the mystery of anesthesia. off and we need personalized on a c.c.i. that s the point but we don t have that. eklund is a door like up stuff coming elections from a. president at once ruling party the regularities mount gambier. is still in the race. supporters see him as the best hope for saving
a reaction to stimulus. of our conscious reaction to stimuli. but for psychologists or social scientists this has nothing to do with consciousness. scientists long believed anesthesia switched off the entire brain like a light switch but as schneider has observed in fact only certain brain regions marked red here are less active under anesthesia. these regions are part of the brain s functional network where several brain areas work together to achieve efficient connectivity. these networks are responsible for processing incoming stimuli such as sound or pressure and interpret in them to form conscious perceptions and as the zia disrupts these networks. during reduced consciousness the primary sensory areas the parts of the brain
