Objective: To explore the prevention efficacy of auricular points plaster therapy on gastrointestinal reaction caused by fundus fluorescein angiography (FFA). Methods: We selected 583 patients who underwent fundus fluorescein angiography in the special examination department of our hospital from October 2019 to April 2020, and divided these patients into experimental group (n=298) and control group (n=285). The control group was given routine nursing measures before the examination. The experimental group was treated with auricular points plaster therapy on the basis routine nursing measures before the examination. The gastrointestinal reactions, degree of patient compliance and comfortableness during the examination were compared between the two groups. Results: The incidence of gastrointestinal reaction in the experimental group was lower than that of control group (P<0.05). The score of patient compliance degree was 2.87±0.35 in the experimental group and 2.96±0.19 in the control group, and there was a significant difference between the two groups (P<0.001). Degree of comfortableness was 3.93±0.70 in the experimental group and 3.91±0.56 in the control group. There was no significant difference between the two groups (P=0.122). Conclusion: Auricular points plaster therapy can reduce the incidence of gastrointestinal reaction caused by fundus fluorescein angiography, which is safe and reliable, easy to operate. In addition, the auricular points plaster therapy will not affect patient’s comfortness during examination, and will comply the patients to the examnination smoothly. is helpful for patients to complete the examination comfortably and safely
