Introduction

Development of an acute cerebral dysfunction in a form of delirium after cardiac surgeries is common general medical problem that associated with prolonged hospital stay after the surgery, risk of development of infection, risk of subsequent neurocognitive changes, and postoperative morbidity

Objectives

To compare risk of development of postoperative delirium in elderly patients with and without hippocampal dysfunction

Methods

Selective observational longitudinal study of the same group of objects in pre and postoperative period

Results

For the diagnosis of degenerative process in CNS on early stages Free and cued selective reminding test immediate recall (FCSRT-IT) was shown to be the most sensitive. Based on learning of verbal material and semantic cues with recalling, FCSRT-IT allows differentiating amnestic disturbances hippocampal type from secondary disturbances of memory due to neurodynamic changes

Conclusions

Hippocampal dysfunction is a factor of developing of postoperative delirium in elderly patients that requires using additional measures in patients with mild cognitive disturbance to prevent developing of postoperative delirium

Disclosure

No significant relationships.
