At the level of molecules and cells, ketamine and dexmedetomidine work very differently, but in the operating room they do the same exact thing: anesthetize the patient. By demonstrating how these ...

Newswise — ANN ARBOR, Mich. - When patients undergo major surgery, they’re often put under anesthesia to allow the brain to be in an unconscious state. But what’s happening in the brain during that ...

Investigators at Massachusetts General Hospital (MGH) and Massachusetts Institute of Technology (MIT) have identified for the first time a pattern of brain activity that appears to signal exactly when ...

An advanced closed-loop anesthesia delivery system that monitors brain state to tailor propofol dose and achieve exactly the desired level of unconsciousness could reduce post-op side effects. If ...

Using a novel technique for analyzing neuron activity, the researchers found that the drug propofol induces unconsciousness by disrupting the brain’s normal balance between stability and excitability.

More than providing a good readout of unconsciousness, Brown added, the new algorithms offer the potential to allow anesthesiologists to maintain it at the desired level while using less drug than ...

Researchers have identified patterns of brain activity that correlate to the loss and recovery of consciousness while a patient undergoes general anesthesia. Their findings, reported yesterday in the ...

A new study finds that an easily measurable brain wave shift of phase may be a universal marker of unconsciousness under general anesthesia. At the level of molecules and cells, ketamine and ...

Patients are usually under anesthesia when undergoing major surgery to allow the brain to be in an unconscious state. But what happens in the brain during unconsciousness is not known. The mystery ...
