Patients with sepsis often require surgery or imaging procedures under general anesthesia, yet there is no standard regimen for anesthetizing septic patients. Of volatile (inhaled) anesthetics, sevoflurane and isoflurane are the most commonly used drugs, despite their undetermined mechanisms of action. A novel study suggests that the type of drug used in general anesthesia could be critical to the survival of patients with sepsis.
