ABSTRACT

Objective To evaluate effectiveness of evidence-based nursing practice of postoperative delirium management during cardiac surgery under cardiopulmonary bypass.Methods The best evidence was selected for the prevention and management of delirium after cardiac surgery under cardiopulmonary bypass.From May 2022 to April 2023,the evidence-based nursing practice was developed and applied into the Department of Cardiovascular and Macro-vascular Surgery of a tertiary A general hospital in Wuhan.The nurses'knowledge,belief and practice of postoperative delirium,incidence of postoperative delirium and subdelirium syndrome,the implementation rate of examination indicators were compared before and after the application of evidence.Results A total of 27 articles were finally included.Based on this,23 pieces of the best evidence were selected,and 27 review indicators were constructed.Through evidence-based practice,the scores of nurses'knowledge,belief and practice questionnaire were significantly increased from(100.81±13.92)to(105.51±10.35)(P＜0.05).The implementation rate of 24 indicators was significantly higher compared with baseline review(P＜0.05).The incidence of delirium decreased from 43.5％ to 34.7％(P=0.120).The incidence of postoperative subdelirium syndrome decreased from 55.1％ to 40.1％(P=0.010).The duration of postoperative delirium and sub delirium significantly decreased,respectively(P＜0.05).Conclusion Evidence-based practice can reduce the incidence of subdelirium syndrome,and it can reduce postoperative delirium and the duration of subdelirium syndrome.It can improve nurses'knowledge and practice of postoperative delirium care.
