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) , Hegu(L14), Yanglingquan(GB34), Zusanli(ST 36) and Renying(ST9) acupoints. Patients will receive TEAS 30min before anesthesia until being discharged from the post-anaesthesia care unit (PACU). The same treatment for 30 min will be performed on the 1st, 2nd and 3rd days after surgery.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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

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

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

TEAS group

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) , Hegu(L14), Yanglingquan(GB34), Zusanli(ST 36) and Renying(ST9) acupoints. Patients will receive 30min TEAS before anesthesia until be discharged from the post anaesthesia care unit (PACU). The same treatment for 30 min will be performed on the 1st, 2nd and 3rd days after surgery.The stimulation intensity will be adjusted in accordance with the maximal level tolerated by each patient.

Group Type EXPERIMENTAL

transcutaneous electrical acupoint stimulation

Intervention Type DEVICE

transcutaneous electrical acupoint stimulation Transcutaneous electrical acupoint stimulation (TEAS) is a contemporary modification of traditional acupuncture that sends electrical impulses into acupoints through electrodes on the skin surface. In the TEAS group, patients will receive TEAS 30min before anesthesia until be discharged from the postanaesthesia care unit (PACU). The same treatment will be performed on the 1st, 2nd and 3rd days after surgery.The stimulation intensity will be adjusted in accordance with the maximal level tolerated by each patient.
