Summary

Introduction:

Severe acute pain after cesarean section is an independent risk factor for the development of chronic pain and increases the risk of postpartum depression threefold. Pain also reduces the mother's ability to breastfeed and care for her child. This study aimed to evaluate the supportive effectiveness of auricular acupressure in reducing incision pain and uterine contraction pain in women undergoing cesarean section, compared with sham auricular acupressure.

Methods:

A randomized, controlled, single-blind clinical trial was conducted in seventy women undergoing cesarean section, randomly allocated (1:1) to an auricular acupressure or sham group. The study group received vaccaria seeds, and the sham group received non-vaccaria patches on both ears. Both groups were treated at the Shenmen, Lung, Internal Genitalia, Pelvis, Subcortex, and Sympathetic points. Pain was assessed using the Visual Analog Scale (VAS), and diclofenac consumption was recorded over the first 48 hours postpartum.

Interventions

OTHER

Auricular Acupressure

In the Auricular Acupressure group, participants received auricular acupressure using vaccaria seeds applied to the following points on both ears: Ear Shenmen (TF4), Lung (CO14), Internal Genitalia (TF2), Pelvis (TF5), Subcortex (AT4), and Sympathetic (AH6), in addition to standard postoperative care. Each participant received a single treatment session within 5 hours after cesarean section, once transferred to the Obstetrics Department. Seeds were retained for 2 days. All acupuncture procedures were performed by licensed traditional medicine physicians who had been trained and standardized before the study.

OTHER

Sham Auricular Acupressure Group

In the Sham Auricular Acupressure Group, participants received adhesive patches without seeds, identical in size and appearance to the Auricular Acupressure Group patches, applied to the same auricular points. Both groups received standard postoperative care.
