Auricular Therapy and Basic Care for Blocked Milk Ducts After Cesarean Delivery
Effectiveness of Auricular Acupressure Combined With Basic Care for Blocked Milk Ducts After Cesarean Delivery: A Randomized Controlled Trial
The goal of this clinical trial is to evaluate whether auricular acupressure combined with basic care can improve symptoms in postpartum women with blocked milk ducts after cesarean delivery. The main questions it aims to answer are:
- Does auricular acupressure combined with basic care reduce breast pain more effectively than basic care alone?
- Does the combined approach improve the severity of milk duct blockage compared with basic care alone?
- What adverse effects may occur in participants receiving auricular acupressure? Researchers will compare auricular acupressure combined with basic care to sham auricular acupressure plus basic care to determine whether the intervention provides additional benefits.
Participants will:
- Receive auricular acupressure (or sham auricular acupressure at non-therapeutic ear points) for 3 days.
- Be instructed to perform basic breast care under the supervision of midwives three times daily for 3 days.
- Record daily activities in monitoring forms, including breastfeeding times, and whether they performed warm compresses and breast massage.

상세 설명
This randomized, single-blind, controlled clinical trial aims to evaluate the effectiveness and safety of auricular acupressure combined with basic breast care in postpartum women with blocked milk ducts following cesarean delivery.
Participants who meet the eligibility criteria will be randomly assigned to either the intervention group (auricular acupressure plus basic breast care) or the control group (sham auricular acupressure plus basic breast care). Auricular acupressure will be applied using semi-permanent auricular pellets at therapeutic ear acupoints on the ear ipsilateral to the affected breast, while the control group will receive sham intervention at non-therapeutic points. Both groups will receive standardized basic breast care, including frequent breastfeeding or milk expression, breast massage during feeding, and warm compresses before feeding.
The intervention will be administered over 3 consecutive days. Participants will be instructed and supervised by trained midwives and will perform self-care during the study period. Outcomes will be assessed at baseline and daily during the intervention period.
The primary outcome is the change in breast pain score measured by the Numeric Rating Scale (NRS). Secondary outcomes include changes in the severity of blocked milk ducts, use of rescue analgesic medication, and incidence of adverse events.
This study is designed as a randomized controlled trial to evaluate the effectiveness of auricular acupressure combined with basic breast care in postpartum women with blocked milk ducts following cesarean delivery. The sample size was calculated based on the primary outcome of pain intensity measured using the Numeric Rating Scale (NRS). A between-group difference of 1.8 NRS points was considered clinically meaningful. Using a two-sided significance level of 0.05, a power of 80%, and an estimated standard deviation of 2.56, the minimum required sample size was 32 participants per group. After allowing for an anticipated attrition rate of 10%, a total of 72 participants were recruited and randomized equally to the intervention group (n = 36) and the control group (n = 36).

실험적: Auricular Acupressure + Basic Care
In addition to standard basic breast care, participants will receive ear acupressure treatment using ear acupressure beads applied to therapeutic points on the ear corresponding to the affected breast, for three consecutive days.
|
Auricular acupressure involves stimulation of specific ear acupoints corresponding to body organs.
In this study, semi-permanent auricular needles (auricular pellets) will be applied to 4 therapeutic acupoints: Breast AH11, Shenmen TF4, Endocrine CO18, Central Rim AT2-4 on the ear ipsilateral to the affected breast.
Needles will be retained for 3 days to provide continuous stimulation.
Participants will be prompted to gently press the points 3 times daily.
All procedures will be performed by a licensed traditional medicine physician following standardized protocols.
다른 이름들:
Standardized basic breast care includes frequent breastfeeding (at least 8 times per day or milk expression if needed), gentle breast massage during feeding, and warm compresses (40-42°C for 10 minutes before feeding).
Participants will be instructed and supervised by trained midwives three times daily and perform self-care at other times.
Adherence will be recorded using monitoring forms.

다른 이름들:
Sham auricular acupressure will be performed using semi-permanent auricular needles applied to 4 non-therapeutic ear points: Wrist SF2, Jaw LO3, Urethra HX3, Outer Nose TF1-2) unrelated to the pathophysiology of blocked milk ducts.
The procedure, duration (3 days), and participant instructions will be identical to the active intervention to maintain blinding.
All procedures will be performed by a licensed traditional medicine physician.
