Abstract: Objective To explore the influence factors of stress injury of adult patients after cardiac surgery in intensive care unit (ICU). Methods A retrospective analysis was performed on 322 cases of postoperative cardiac surgery adult patients admitted to the ICU of the First Affiliated Hospital of Xinjiang Medical University from January to December 2017. The clinical data and stress injury of the patients were described. Univariate analysis and multivariate logistic regression analysis were used to determine the influence factors of stress injury in postoperative cardiac surgery patients. Results The multiple logistic regression analysis showed that age and intraoperative blood transfusion volume were independent risk factors for stress injury after cardiac surgery in ICU patients (P<0.05). Gender, length of extracorporeal circulation, and intraoperative minimum body temperature were protective factors for stress injury after cardiac surgery in ICU patients (P<0.05). Conclusion The incidence of stress injury of adult patients after cardiac surgery in ICU is high, age, gender, intraoperative blood transfusion volume, length of extracorporeal circulation, and intraoperative minimum body temperature were influence factors.A comprehensive assessment of the patients is recommended. More attention should be paid to intraoperative blood transfusion volume, extracorporeal circulation time and intraoperative minimum body temperature. Meanwhile, predictive measures should be taken for patients thus to reduce the incidence of stress injury of ICU patients after cardiac surgery and to improve the quality of nursing service.
