The Effect of Auriculotherapy on Nausea, Vomiting, and Anxiety in Patients Undergoing Elective Cesarean Section with Spinal Anesthesia: A Clinical Trial Study

Nausea, vomiting, and anxiety are common complications during and after spinal anesthesia. Auriculotherapy as a complementary medicine can be useful for reducing nausea, vomiting, or anxiety. This study was performed to evaluate the effects of auriculotherapy on nausea, vomiting, and anxiety in patients undergoing elective Cesarean Section (CS) with spinal anesthesia.

The present study was a clinical trial study that was performed on 56 pregnant women selected as CS candidates in Ommolbanin Hospital in Mashhad during the years 2016–2017. In the intervention group, 1 h before spinal anesthesia, auricular acupoint stimulation was performed at four points bilaterally, for 20–30 seconds at each point. Evaluations were done by the following questionnaires: State‑Trait Anxiety Inventory (STAI), Visual Analog Scale (VAS), and Vomiting Assessment Form.

The mean anxiety (SD) before the intervention in the intervention group and the control group was 47.88 (8.67) and 47.84 (10.49), respectively, and 4 h after the intervention, it was 40.23 (10.19) and 42.88 (12.18) in the intervention and control groups, respectively. These results were significant in the intervention group (p </em>= 0.008). 30–40 min before and 4 h after the surgery, the severity of nausea and vomiting was low in both groups and no significant difference was observed between the two groups during the surgery and in the recovery room (p </em>> 0.05).

According to the results, auriculotherapy could reduce anxiety in CS patients with spinal analgesia. The results also showed that auriculotherapy reduced the severity of nausea and vomiting, but these changes were not significant.
