Following deep anesthesia, consciousness and cognitive processes unfold over time. The prefrontal cortex is the first brain area to recover, with areas associated with reaction time and attention taking longer to return to pre-anesthesia states.
Women who are given a general anesthetic during a cesarean section delivery have a 54% higher risk of developing postpartum depression. The odds of suicidal thoughts or self-inflicting injury increased to 91%. The study points to a potential protective effect on mental health for regional anesthesia during cesarean section compared to general anesthetic.
Study reveals anesthesia activated neurons have been discovered in the hypothalamus. Activation of AANs promotes slow-wave sleep, extending the effects of anesthesia, while inhibition of AANs shortens the duration of general anesthetics and disrupts natural sleep.
A new study reveals animals injected with caffeine during the last 10 minutes of exposure to general anesthetic woke more quickly than those injected with saline solution. Waking times became significantly quicker with higher doses of caffeine.
Using optogenetics to activate dopamine receptors in the ventral tegmental area could help people regain consciousness following general anesthesia, researchers report.
A new study reveals the neurological mechanisms at work during ketamine anesthesia.
A new study could help doctors to predict an individual's response to general anesthetics.
Two new studies detail the way general anesthesia affects the brains of both older patients and children.
