Intraoperative analgesia management by monitoring the analgesia nociception index in gynecological surgeries involving erector spinae plane block: a randomized controlled study
Authors' conclusion
ANI monitoring in patients undergoing gynecological surgery under general anesthesia with ESPB reduced opioid consumption during the intraoperative period.
Study context
- Population
- ASA I–III patients scheduled for hysterectomy under GA with preoperative bilateral ultrasound-guided ESP block
- Participants
- 80 patients
- Comparison
- Analgesia Nociception Index (ANI) vs Control
- Primary endpoint
- Intraoperative remifentanil consumption
Primary result
As reported in the abstract
- Lower in the ANI group than in the control group
- ANI vs Control: P < 0.001
Further findings
| Outcome | P value |
|---|---|
| NRS scores and additional analgesic requirements in the recovery unitBoth lower in the ANI group | P < 0.05 |
Numerical rating scale (NRS) scores and additional analgesic requirements in the recovery unit
- Both lower in the ANI group
Safety
Nausea or vomiting in the recovery unit
- No significant differences between the groups
