Official title
Efficacy of Transcutaneous Electrical Acustimulation on Postoperative Bowel Function Recovery in Elderly Patients With Colorectal Cancer: A Multicenter Randomized Controlled Trial Study Protocol
Overview
The goal of this clinical trial is to clarify the efficacy and safety of transcutaneous electrical acustimulation (TEA) in elderly patients with colorectal cancer, and to evaluate its clinical value in promoting postoperative intestinal function recovery and reducing the incidence of intestinal complications. The main questions it aims to answer are: Can TEA promote the recovery of intestinal function in elderly patients with colon cancer after surgery? What medical problems might occur to the participants when using TEA? The researchers will compare TEA with the control group (non-acupoint sham stimulation) to see if TEA is effective in promoting the recovery of intestinal function after surgery. Participants will: Starting from the first day after the surgery, they received TEA or sham stimulation twice a day for a total of 3 days. Record the time of the first defecation, defecation, and eating. Record their symptoms and adverse events.
Interventions
- Device TEA
The subjects in the TEA group were placed in the supine position and received transcutaneous electrical acupoint stimulation at the bilateral PC6 and bilateral ST36 . After confirming the location of the acupoints , special skin treatment was carried out. The stimulation parameters for PC6 were set as follows: 0.1 seconds of opening stimulation, 0.4 seconds of closing stimulation, pulse width of 0.5 ms, pulse frequency of 100 Hz, and amplitude ranging from 1 to 10 mA (based on the maximum level - Device sham-TEA
Sham-TEA was the same except that non-acupoints were used to replace ST36 and PC6. The sham-acupoint for PC6 was located at about 15-20 cm away from PC6 (up to the elbow and outside of the coastal margin of the forearm not on any meridian) and the sham-point for ST36 was located at 10-15 cm down from and to the lateral side of ST36 not on any meridian
