Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients who meet the enrollment criteria will be randomized 1:1 to either the transcutaneous electrical acupoint stimulation (TEAS) or the sham groups. In the TEAS group, the acupoints are bilateral neiguan (PC6), Zusanli (ST 36), Hegu (L14) and Waiguan (SJ5) acupoints. The treatment will consist of two phases: a 30-minute stimulation administered 30 minutes before anesthesia induction, and a 30-minute stimulation session once daily on postoperative days 1, 2, and 3. The stimulation intensity will be adjusted in accordance with the maximal level tolerated by each patient. Patients in the sham group will receive electrode attachment but without stimulation.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Patients who meet the enrollment criteria will be randomized 1:1 to either the transcutaneous electrical acupoint stimulation (TEAS) or the sham groups using a computer-generated random number table. After the randomization, use the opaque envelope, hide each group envelope into an opaque envelope, the envelope outside the code, will be sealed to the researcher, when the study, if the inclusion criteria, then open the corresponding numbered envelope, and intervene according to the group scheme in the envelope.

Primary Study Purpose

TREATMENT

Blinding Strategy

DOUBLE

Participants Outcome Assessors

Blinding of participants will be maintained throughout the observation period. The sham group will receive electrode attachment but without stimulation, Throughout the study, for adequate blinding, an opaque tape will be applied to the patient's skin above the electrodes, and the patient's target acupoints will be wrapped in a blanket. All patients will be informed that they might or might not feel a tingling sensation around the acupoints when the TEAS device is working. The patients should not be unblinded until the statistical analysis of the study data is completed.

Study Groups
