NCT02707705

Brief Summary

Preoperative anxiety before cesarean section is common and may be severe. Stress consequences are often deleterious for the mother and for the upcoming newborn. Means to reduce anxiety before cesarean section are limited. Anxiolytic drugs are avoided in the context of the birth of a newborn. Auricular acupuncture has been shown to relieve anxiety disorders. The aim of this study is to evaluate the anxiolytic effect of auricular acupuncture administered before an elective cesarean section. Anxiety will be measured at T0: inclusion (approximately 1-2 hours before cesarean section) and T1: departure to surgical unit (approximately 30 minutes to 1 hour after T0). Patches (needle or needle-free) will be set up at T0 just after the initial anxiety assessment (anxiety Visual Analog Scale aVAS).

Outcome Measures

Primary Outcomes (1)

  • Comparison of anxiety variation between group A (Auricular acupuncture, needle patch) and group P (needle-free patch) via visual analog scale.

    Degree of reduction in anxiety VAS score between T0 and T1 and comparison between group A and group P. Anxiety will be assessed using a Visual Analogue Scale scoring between 0 (complete absence of anxiety) and 100 (greatest possible level of anxiety).

    measured at the inclusion (T0) and 30min/1h after inclusion (T1).

Secondary Outcomes (7)

  • Potential placebo effect of auricular acupuncture by measuring Anxiety variation between the 3 groups.

    measured at the inclusion (T0), 30min/1h after inclusion (T1), 1h/2h after inclusion (incision T2) and 3h/4h after inclusion (back in post-operative surveillance room T3).

  • To evaluate anxiolytic effect of auricular acupuncture on anxiety measured by Amsterdam Preoperative Anxiety and Information Scale (APAIS).

    measured at the inclusion (T0) and 30min/1h after inclusion (T1).

  • To evaluate the effect of auricular acupuncture on parasympathetic tone measured by Analgesia Nociception Index (ANI).

    measured at the inclusion (T0) and 30min/1h after inclusion (T1).

  • Study of the correlation between ANI and anxiety VAS.

    measured at the inclusion (T0) and 30min/1h after inclusion (T1).

  • To evaluate the effect of auricular acupuncture on perioperative pain.

    Measured at1h/2h after inclusion (incision T2) and 3h/4h after inclusion (back in post-operative surveillance room T3).

  • +2 more secondary outcomes

Study Arms (3)

: Auricular Acupuncture (needle patch) group A

EXPERIMENTAL

Needle patch: Patients receiving the auricular acupuncture protocol with needles inserted on adhesive tape.

Device: Apply an auricular acupuncture protocol by stimulating specific points of the ear with needles inserted on adhesive tape (Pyonex®).Procedure: Disinfection

Needle-free patch: group P.

PLACEBO COMPARATOR

Patients who received the auricular acupuncture protocol with adhesive tape without needles.

Device: Apply a device having no real effectProcedure: Disinfection

No intervention: group C

NO INTERVENTION

Patients without any device or intervention.

Interventions

Intervention Description : The auricular acupuncture protocol is based on an anxiolytic triad of three points selected according to the World Health Organization classification. These points are detected and located precisely by a differential detector starting with the right ear, and in the absence of response, the points are searched on the left ear. The detected points are treated by application of adhesive tape with needles of diameter 0.2 mm and length 0.9 mm. Data collected : * T0 : anxiety VAS, pain VAS, APAIS, ANI, arterial pressure and cardiac frequency * T1 : anxiety VAS, pain VAS, APAIS, ANI, arterial pressure, cardiac frequency and side effects * T2 : anxiety VAS, pain VAS, arterial pressure, cardiac frequency and side effects * T3 : anxiety VAS, pain VAS, arterial pressure, cardiac frequency and side effects

: Auricular Acupuncture (needle patch) group A
