Summary
There are many methods used for the assessment of pain in the area of anesthesia including
heart rate variability which reflects the influence of the autonomic nervous system on the
heart. An original index, the ANI (Analgesia Nociception Index), quantifies pain during
anesthesia. Obstetric epidural analgesia is particularly suited to evaluate ANI in conscious
patients with a comparison of ANI with the measurement of pain by a visual analog scale
(VAS).
Evaluation of ANI is performed just before epidural catheter insertion and during the 10
first minutes after saline, sufentanil or lidocaine epidural administration.
