Abstract: Objective： To explore the effect of diversified preoperative visit on postoperative ICU syndrome in patients with coronary artery bypass.Methods： 56 patients with cardiac surgery were randomly divided into experimental group (28 cases) and control group (28 cases)， patients in control group were educated by thoracic vascular surgical ward nurses and operating room nurses on routine preoperative instruction. On the basis of control group， patients in the experimental group were taken diversified preoperative visits. By using the fuzzy evaluation of ICU consciousness scale (CAM)， ICU environment stressor scale (ICUESS) and self-evaluation of anxiety scale (SAS)， compare two groups of patients with ICU admission time and patient satisfaction， at the same time evaluate ICU syndrome such as delirium and anxiety and pressure rating of patients.Results： ICU admission time in the experimental group was statistically significant shorter than control group patients(P<0.05). Patients delirium value， anxiety and stress scores in experimental group were significantly lower than the control group(P<0.05). Satisfaction rate of patients in experimental group was obviously higher than that of control group， experimental group patients′ satisfaction rate was 96.43%， control group patients′ satisfaction rate is only 71.43%. Conclusion：Diversification of preoperative visits can effectively shorten the coronary bypass patients′ postoperative ICU admission time， reduce the incidence of ICU syndrome. This preoperative visit method has more operation feasibility and practicability， worthy of clinical popularization and application.
