Effect of Epidural Analgesia on the Parameter ANI During Childbirth (APD-ANI)
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.

|Official Title:||Effect of Epidural Analgesia on the Parameter ANI During Childbirth|
- Comparison of the ANI parameter with the VAS during labour [ Time Frame: 2 hours ]The main objective of the research is to evaluate ANI as a measurment of pain caused by uterine contractions.
- Effects of epidural sufentanil and of epidural local anesthetic on ANI [ Time Frame: 2 hours ]The secondary objective is to compare the effects of epidural sufentanil and a local anesthetic on the parameter ANI.
- Effects of anxiety score on ANI [ Time Frame: 2 hours ]The secondary objective is to study the effects of anxiety on the parameter ANI.
