Objective To investigate the application value of nutrition education in the radical operation of abdominal aortic aneurysm. Method 96 patients with radical surgery from Qingdao Municipal Hospital from October 2017 to October 2019 were selected, by control group (48 cases, routine care) and the observation group (48 cases, routine nursing combined nutrition education), comparing the rehabilitation effects, nutritional indicators and quality of life between the two groups, referring also to the anxiety self⁃assessment scale (SAS) and depression self⁃rating scale (SDS) determines the patient's psychological status. Result The first exhaust time, off⁃bed activity time and hospitalization time in the observation group were shorter than those in the control group. Mental state scores were lower than in the control group, the compliance and GQOLI⁃74 scores were higher than those in the controls. The difference was statistically significant (P<0.05), the weight of the observation group was (68.16±6.32) kg, the BMI was (23.02±0.54) kg/m2, the serum albumin level was (37.2± 2.4) g/L, and the serum transferrin level was (2.45±0.36) g /L, the serum prealbumin level is (267.27±25.12) mg/L, and the total iron binding capacity is (56.17±6.24) μmol/L, which are higher than the control group (64.32±5.44) kg and (21.72±0.78) kg /m2, (32.1±1.8)g/L, (2.16± 0.32) g/L, (215.12±22.26)mg/dl and (50.34±5.21) μmol/L, the difference was statistically significant (P<0.05).
