Abstract

A retrospective study of postoperative delirium after adult spinal deformity (ASD) surgery. To identify the risk factors of post-ASD surgery delirium, including nutritional state before surgery. Recently, malnutrition was reported as one of the risk factors of delirium. The prognostic nutritional index (PNI) and controlling nutritional status index (CONUT) scores are simple methods of nutritional evaluation. However, there are no reports that verify that delirium is related to the PNI and CONUT score in patients who have undergone ASD surgery. A consecutive 319 patients who underwent ASD surgery were divided into a delirium group (group D) or nondelirium group (group ND). Preoperative risk factors, including PNI, were assessed. Group D consisted of 30 patients and group ND consisted of 289 patients. There was significant difference in age (group D:group ND = 73:62, P = 0.000), serum albumin (4.2:4.3, P = 0.028), operative time (422:395 min, P = 0.029), PNI score (49:52, P = 0.011), and CONUT score (1.7:1.1, P = 0.046). Using multiple logistic regression analysis, we found significant risk factors for delirium to be age (P = 0.006, odds ratio = 1.11, 95% confidence interval = 1.03-1.19) and PNI (P = 0.003, odds ratio = 0.87, 95%...Continue Reading
