Anesthesia administration is an integral part of conducting a surgery or procedure. An extensive research involving functional MRI (fMRI) has determined that different anesthetic drugs and doses cause different effects in the brain. This article provides an overview of the effects of routinely used anesthetic drugs on the brain as reported in various scientific studies. The process of anesthesia is considered successful only when a patient experiences amnesia, analgesia, muscle relaxation, and loss of consciousness.
However, high or low does have different effects on patients, and sometimes there are incidences of patients waking up in the middle of surgery, while others have experienced cognitive decline postoperatively. For surgery, the recommended dose of general anesthesia is at least 1 minimum alveolar concentration (MAC). Studies indicate that 1 MAC inhaled anesthesia is…
