Beskrivelse
Inclusion Criteria:
- Age 18-40 years, gestational age 37-41 weeks, singleton full-term pregnancy;
- Planned elective or emergency cesarean section, using epidural anesthesia (0.1~0.2 mg/kg of morphine administered intrathecally during surgery);
- American Society of Anesthesiologists (ASA) classification I-III;
- Conscious and able to cooperate to complete scale assessments, serum sample collection, and postoperative follow-up;
- Voluntarily participate in the study and sign the informed consent form.
Exclusion Criteria:
- Presence of contraindications for tDCS (such as skull defects, intracranial metal implants, history of epilepsy, coagulation disorders);
- Allergy to opioids or a history of severe OEI;
- Presence of skin diseases (such as eczema, urticaria), liver diseases (cholestasis), mental disorders, or cognitive impairments;
- Coexisting pregnancy complications (preeclampsia, gestational diabetes, autoimmune diseases);
- Use of medications within the past week that may affect itch assessment, such as antihistamines, 5-HT3 receptor antagonists, or anti-inflammatory drugs.

Sham-komparator: control group (sham stimulation group)
|
Sham stimulation group (control group): The anode of the electrical stimulator is placed on the left dorsolateral prefrontal cortex (F3 region) and the cathode on the right mastoid area.
A current of 1.5 mA is applied only during the first 30 seconds after the start of stimulation, after which the current is reduced to 0 mA.
All other procedures (electrode placement, stimulation duration, intervention frequency) are the same as those in the experimental group.

Eksperimentel: Case group (tDCS group)
|
Patients in the transcranial direct current stimulation (tDCS) group had the anode of the tDCS device placed on the left dorsolateral prefrontal cortex (F3 area) and the cathode on the right mastoid.
The tDCS was administered on the day of surgery (starting within 5 minutes after delivery of the fetus and ending upon transfer to the PACU after surgery).
The current intensity was 1.5 mA.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Incidence of itching within 24 hours after surgery (defined as VAS itching score ≥1)
Tidsramme: 24 hours after surgery
|
The VAS scoring standard for the degree of itching is a tool used to assess the severity of itching.
VAS stands for Visual Analog Scale.
The following are the standards for VAS scoring of itching severity: 0 points: No itching.
1-3 points: Mild itching, does not affect daily life.
4-6 points: Moderate itching, somewhat affects daily life.
7-9 points: Severe itching, seriously affects daily life, requires active treatment.
10 points: Extremely severe itching, unbearable, requires immediate treatment.
