To evaluate the effectiveness of dezocine combined with auricular point sticking to relieve the postoperation pain of painless gastric endoscopic mucosal resection in elderly patients.

A total of 300 elderly patients who underwent painless endoscopic mucosal resection in Zhejiang Hospital during January 2020 and February 2021 were randomly divided into three groups. Among them, 100 cases were treated with dizocine before operation combined with auricular point sticking after operation (dizocine + auricular point sticking group), 100 cases were treated with dizocine only (dizocine group), and 100 cases were not treated with the above intervention measures (control group). Excluding 30 cases with peptic ulcer found during gastroscopy, new focus found during operation and delayed perforation after operation, there were 88 cases in the dizocine + auricular point sticking group, 93 cases in the dizocine group and 89 cases in the control group. Visual analogue scale (VAS) was used to score the degree of abdominal pain at 3, 12, 24 and 48 hours after operation, and the postoperative adverse reactions were recorded. Chi-square test was used for comparison of counting data, analysis of variance was used for comparison of measurement data, and mixed effect model was used to compare the degree of abdominal pain.

The incidence of postoperative abdominal pain in the dizocine + auricular point sticking group and dizocine group was significantly lower than that in the control group (χ²=8.037, 5.924, P < 0.05 or 0.01), but there was no significant difference between the two groups (χ²=0.221, P > 0.05). The degree of abdominal pain was differed among groups and among different time points (F=7.718, 29.690, P < 0.01), which was lighter in dizocine + auricular point sticking group and dizocine group compared with the control group (P < 0.01), and that at 12 and 24 hours after operation was higher than that at 3 and 48 hours after operation (P < 0.01). There was no significant difference in the incidence of postoperative adverse reactions among the three groups (χ²=4.260, P > 0.05) .

Dizocine combined with auricular point sticking has a good effect on relieving the pain of elderly patients after endoscopic mucosal resection without obvious adverse reactions, which is worthy of clinical application.
