Objective:To investigate the prognosis of marginal donor heart in heart transplantation.Methods:The clinical data of consecutive heart transplant recipients and donors in Zhengzhou 7th. People’s Hospital from April 2018 to November 2022 were retrospectively included. According to the definition of marginal donor hearts, the patients were divided into conventional donor hearts group (117 cases) and marginal donor hearts group ( 62 cases), the data before and after heart transplantation of the two groups were analyzed.Results:The main reason for the formation of marginal donor hearts was the cold ischemia time of donor hearts >6 h; it was easier to receive marginal donor hearts with ECMO and MV before operation; the use of marginal donor hearts in heart transplantation increased postoperative mechanical ventilation time, surgical post-intensive care unit length of stay; patients with marginal donors had lower survival than conventional donors, but did not produce a significant difference in survival after heart transplantation.Conclusion:The application of marginal donor heart in heart transplantation is an effective method to solve the shortage of heart organs and reduce the death of transplant waiting persons.

Objective To analyze the application effect of risk nursing based on failure mode and effect analysis(FMEA)theory in the management of delirium in elderly patients after heart valve replacement surgery.Methods A total of 210 elderly patients undergoing coronary artery bypass grafting were included in the study,and were randomly divided into control group(n=105)and ex-perimental group(n=105)using a random number table method.The control group received routine care,while the experimental group received risk care based on FMEA theory on the basis of the con-trol group.The incidence of delirium,degree of pain before and after intervention,negative emo-tions,and sleep quality between the two groups were compared.Results The incidence of postoper-ative delirium and 24 h postoperative pain score in the experimental group were lower than those in control group(P＜0.05).After intervention,the scores of Self-rating Anxiety Scale,Self-rating De-pression Scale in the experimental groups were lower than those in control group(P＜0.05).After the intervention,the scores of sleep quality,sleep time,sleep efficiency,sleep disorders,use of hyp-notic drugs,daytime function and total score of Pittsburgh Sleep quality index(PSQI)in experimen-tal group were lower than those in the control group(P＜0.05).Conclusion Risk nursing based on FMEA theory can reduce the incidence of delirium in elderly patients after coronary artery bypass grafting,relieve the degree of postoperative pain,improve negative emotions,and enhance the quality of sleep.
