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.
