상세 설명

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.

측정값 설명
기간
Mean ANI Changes After Intubation
기간: 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
Before vs after intubation
Mean ANI Changes 3 Min After Ketamine Bolus
기간: Before vs 3 min after Ketamine adminstration
ANI was measured pre- and post- i.v. ketamine administration

Mean ANI Changes 5 Min After Ketamine Bolus
기간: Before vs 5 min after Ketamine adminstration
ANI was measured pre- and post- i.v. ketamine administration

측정값 설명
기간
Mean BIS Changes After Intubation
기간: 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).

  • 100-90: awake and responding appropriately to verbal stimulation
  • 80-70: responsive to loud commands or mild shaking
  • 60-40: unresponsive to verbal stimulus; general anesthesia obtained with a low chance for explicit recall
  • <40: deep hypnotic state; possible protective responses still intact
  • <20: burst suppression (EEG pattern characterized by cycles of high-voltage electrical movement alternating with cycles of no activity in the brain); respiratory drive is limited, but possible protective responses still intact
  • 0: totally suppressed EEG (flat line)
Before vs after intubation
Mean BIS Changes 3 Min After Ketamine Bolus
