Abstract
Closed-loop control of anesthesia based on continuous feedback from processed electroencephalography adjusts drug dosing to target a desired depth of hypnosis during dynamic clinical circumstances, freeing the anesthesiologist to focus on more complex tasks. We describe a case of closed-loop control of total intravenous anesthesia in which a sudden loss of blood required immediate intervention. This case illustrates that closed-loop control of drug delivery maintained an appropriate depth of hypnosis during a rapidly changing surgical situation, and that processed electroencephalography may be a useful adjunct indicator for cerebral hypoperfusion.
