Effects of IV Administration of Ketamine on the Analgesia Nociception Index (ANI) Measured With the PhysioDoloris
The Effects of Intravenous Administration of Ketamine on the Analgesia Nociception Index (ANI) Measured With the PhysioDoloris Device

Description détaillée
Researchers at the University of Washington are doing this study to find out if a commonly used anesthetic affects patients Analgesia Nociception Index (level of pain relief) during abdominal hysterectomy under general anesthesia.
The investigators will administer routine anesthesia care including Ketamine, a commonly used anesthetic, during the patients surgery. During the patients surgery, the investigators will monitor the patients level of pain relief using the PhysioDoloris monitor, which monitors the routinely used EKG monitor. Though not yet FDA approved, the PhysioDoloris is completely non-invasive and collects data from the EKG monitor.

Mean ANI Changes After Intubation
Délai: Before vs after intubation
|
ANI stands for Analgesia Nociception Index.
Its a dimension less number computed by a pain monitor ranging from 0-100.
An index of 100 means absent pain, and the number decreases as pain increases.
ANI was measured pre- and post- Intubation

Mean BIS Changes After Intubation
Délai: Before vs after intubation
|
BIS was measured pre- and post-intubation. BIS, Bispectral index, is an indication of anesthesia depth and measured by a monitor during surgery (0-100 scale, range described below). Depth of sedation is calculated by measuring cerebral electric activity via an electroencephalogram (EEG).
