ABSTRACT
The objective of the work is to assess the efficacy of the methods of audiological evaluation of the functional state of the central departments of the auditory system in diagnostics of postoperative cognitive dysfunction (POCD). The authors examined 15 patients with generalized atherosclerosis after reconstructive surgery on the lower extremity vessels (the main group) and 10 patients of general surgical profile without the signs of generalized atherosclerosis (the control group). Audiological examination included tonal threshold audiometry, Russian matrix sentence test in noise and dichotic digit test. For POCD diagnostics the authors used the Montreal Cognitive Assessment (MoCA). The studies were performed before and after surgery. A postoperative decrease by 1 or more MoCA points compared to the initial value was considered as a POCD sign. Initially low cognitive background is established to be one of the main risk factors for the POCD development. The article presents the possibility to diagnose the cognitive disorders by means of audiological tests. The presence of signs of central auditory processing disorders can be regarded as a POCD predictor.
