Transcutaneous Electrical Acustimulation on Postoperative Bowel Function Recovery in Elderly Patients
Sponsor: Sir Run Run Shaw Hospital
Summary
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.

TEA
The subjects in the TEA group were placed in the supine position and received electro-acupuncture treatment simultaneously at the bilateral PC6 and bilateral ST36 acupoints . 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 that the subject could tolerate). The stimulation parameters for ST36 were set as follows: 2 seconds of opening stimulation, 3 seconds of closing stimulation, pulse width of 0.5 ms, pulse frequency of 25 Hz, and amplitude ranging from 2 to 10 mA (based on the maximum level that the subject could tolerate).
sham-TEA
Sham-TEA is similar to the real stimulation, but it uses non-acupoints instead of ST36 and PC6. The virtual acupoint of PC6 is located approximately 15 cm to 20 cm away from the PC6 (about 15 cm to 20 cm from the inner wrist，on the outer side of the forearm rib margin，not on any meridian)，and the virtual acupoint of ST36 is located 10 cm to 15 cm below ST36 and slightly to the outside，also not on any meridian.
