A new study outlines how researchers have been able to deliver concentrated amounts of drugs directly into the brains of rats by using ultrasound.
Propofol, the commonly used anesthetic, alters and controls the dynamics of the brain's rhythms. The findings can help doctors better monitor patients under anesthesia with the aid of EEG.
As many as one in four patients who receive anesthesia may suffer accidental awareness during their procedure. Researchers have identified specific brain structures that may predict whether a person will experience accidental awareness under anesthesia. The findings will help identify patients who require higher than average doses of anesthesia.
