Objective:To explore the effect of failure mode and effects analysis (FMEA) on the postoperative complications in patients with cerebral angiography.Methods:Using the convenient sampling method, a total of 167 patients with cerebral angiography who were admitted to Shanxi Provincial People's Hospital from March 2016 to January 2019 were selected as research objects and they were divided into two groups according to the implementation of FMEA. The observation group (after the implementation of FMEA) used FMEA method to calculate of priority risk number (RPN) in failure mode to determine the nursing plan for clinical nursing, while the control group (before the implementation of FMEA) was given routine nursing. The postoperative RPN, complications and nursing satisfaction were compared between the two groups.Results:RPN of each failure mode in the observation group was significantly lower than that in the control group. The total incidence of complications in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.01) . The scores of nursing satisfaction in health education, professional degree of nursing behaviors, nursing requirement satisfaction degree, nursing attitude and nursing skills of the observation group were significantly higher than those of the control group, and the differences were statistically significant ( P<0.01) . Conclusions:FMEA method analyzes the causes of complications of cerebral angiography and formulates targeted nursing plans according to the causes, so as to make the operation process more standardized and scientific, effectively reduce postoperative complications of patients and improve nursing satisfaction.
