Abstract:

Objective To analyze the application effect of intracavity electrocardiogram localization technology in infusion port implantation for gastric cancer patients. Method Forty gastric cancer chemotherapy patients admitted to Liyang People's Hospital from July to December 2024 were selected and randomly divided into a control group and an experimental group, with 20 patients in each group, using a random number table method. The control group used intraoperative X-ray fluoroscopy to locate the position of the catheter, while the experimental group patients used intracavitary electrocardiogram positioning technology to locate the catheter position. The positioning effects of different methods on the catheter tip were compared. Result The surgical time of the experimental group was shorter than that of the control group, and the number of punctures, intraoperative catheter adjustments, and X-ray frequency were all less than those of the control group. However, the accuracy was higher than that of the control group, and the differences were significant (P ＜ 0.001). After surgery, The pain score of the experimental group patients was lower than that of the control group, and their quality of life score was higher than that of the control group, with significant differences (P ＜ 0.001). The incidence of complications such as catheter ectopia, puncture site hematoma, infection, pneumothorax, and arrhythmia in the experimental group was significantly lower than that in the control group (P ＜ 0.05). Conclusion The application of intracavitary electrocardiogram positioning technology in infusion port implantation surgery for gastric cancer chemotherapy patients not only reduces the incidence of complications, optimizes intraoperative operation indicators, reduces pain levels, and improves quality of life.
