Paracervical block anesthesiaBagua Auriculotherapy

Paracervical block anesthesia: The control group received paracervical block anesthesia with 0.1 g lidocaine, without combined Bagua auriculotherapy.

Bagua Auriculotherapy: For the intervention, Vaccaria seeds were attached to selected auricular points using adhesive tape. The auricular skin was disinfected with 75% alcohol wipes. According to Bagua theory, the seeds were placed at the Kan, Li, Gen, and Qian positions, localized based on the Group Standard of Guangdong Provincial Association of Traditional Chinese Medicine (T/GDACM0143-2025): "Bagua Auriculotherapy Localization and Compatibility". Manual pressure was applied using the thumb and index finger pads on each point. The pressing procedure commenced 15 minutes before surgery, with each point pressed 30 times in the sequence of Kan, Li, Gen, and Qian, repeated for three cycles, until sensations of warmth, pain, numbness, or distension were achieved. Immediately after surgical incision, each point was pressed 30 times following the same sequence for three cycles, and immediately after surgery completion, each point was again pressed 30 times for three cycles.

Study summary

To investigate the application of Bagua ear therapy as an adjunctive intervention for perioperative pain management in patients undergoing hysteroscopic surgery, to analyze its effects on intraoperative and postoperative pain, and to compare the differences in pain outcomes between patients undergoing hysteroscopy under local anesthesia and those without anesthesia.

Inclusion Criteria: * Aged 20 to 45 years * Female * Scheduled for diagnostic hysteroscopy * American Society of Anesthesiologists (ASA) Physical Status Classification I or II * Normal comprehension and communication skills, able to complete Numerical Rating Scale (NRS) and Self-Rating Anxiety Scale (SAS) assessments * Willing to provide written informed consent Exclusion Criteria: * Known allergy to auricular plaster or Vaccaria segetalis (Wang Bu Liu Xing) seeds * Active lesions on the ear, such as wounds, ulcers, swelling, or deformity * Severe psychiatric or neurological disorders * Severe cardiovascular or cerebrovascular diseases * Pre-existing significant pain, nausea, vomiting, dizziness, or tinnitus before the procedure

Primary outcome measure(s)

Pain Intensity During Hysteroscopy — During the hysteroscopy procedure and up to 30 minutes post-procedure
Pain intensity measured using the Numerical Rating Scale (NRS), an 11-point scale ranging from 0 (no pain) to 10 (worst imaginable pain). Assessments are performed at five time points: during vaginal disinfection, at hysteroscope insertion, during the procedure, at procedure completion, and 30 minutes post-procedure.
