Wrist actigraphy in anesthesia.
OBJECTIVE
To examine the use of wrist actigraphy during and following anesthesia or monitored sedation and its ability to objectively assess sleep-related events.


METHODS
Uncontrolled study.


METHODS
1100-bed tertiary care municipal, university-affiliated medical center.


METHODS
18 patients who underwent minor to medium lower-body surgical procedures with spinal or epidural anesthesia with sedation by propofol, midazolam, or isoflurane-based general anesthesia.


RESULTS
Wrist actigraphy was measured and evaluated. The actigraphic recordings accurately indicated the presence and time of occurrence of all relevant perioperative events including those related to anesthesia. Actigraphic data were more precise than equivalent attending anesthesiologist's subjective observations. The anesthesiologist detected changes in the patient's activity with a delay of minutes after they had been picked up by the actigraph. The integrated areas of recorded phases of midazolam-induced sedation and the occurrence and reversal of paradoxical reactions were distinctly discernible as such, unlike the less specifically defined description of the anesthesiologist.


CONCLUSIONS
Real time actigraphic monitoring can provide clear-cut and objective indications of changes in the depth of anesthesia or sedation and its associated events during surgery and recovery.
