[Cognitive status assessment after spinal surgery]

38 patients after spinal surgery were involved in the study. Patients were divided into two groups similar by anthropometric factors, pathology and preoperative pain syndrome. The first group included 15 patients older than 60 years (mean age 66 +/- 5.77 years), second group--23 patients younger than 60 years (mean age 43 +/- 10.7 years). The authors analyzed influence of anesthetic method, duration of anesthesia, hemodynamic parameters, BIS values on POCD syndrome. Duration and depth of anesthesia, episodes of hypotension are main predictors of POCD. Maintenance of optimal depth of anesthesia defined by BIS monitoring decreases the frequency of POCD. Patients of all ages with chronic pain syndrome usually have memory and attention disturbances.
