Analysis of risk factors for delirium after coronary artery bypass grafting / 中国实用护理杂志

ABSTRACT

Objective:To investigate the incidence and risk factors of delirium after coronary artery bypass grafting(CABG) and evaluate the predictive efficacy of these risk factors.Methods:The Confusion Assessment Method for the Intensive Care Unit(CAM-ICU) was used to evaluate the incidence of delirium in 314 CABG patients. Multivariate Logsictic regression analysis was used to determine the independent risk factors for delirium after CABG.Results:The incidence of delirium after CABG was 24.8%(78/314). The incidence of delirium after CABG was 25.7%(54/210) in the training set, and 23.1%(24/104) in the validation set. American Society of Anesthesiologists Physical State≥4 points, cardiopulmonary bypass, Mini-Mental State Examination <27 points, mechanical ventilation time, postoperative midazolam application, and serum albumin <30 g/L were independent risk factors for delirium after CABG.In the training set and validation set, patients with delirium score> 2.11 were in high-risk groups, and patients with delirium score ≤2.11 were in low-risk groups.Conclusions:The established delirium predictive model can not only stratify the risk of delirium, but also provide clinical scientific basis for postoperative delirium prevention and early screening.
