摘要：Cardiac and thoracic surgical intervention s are relatively rarely associated with development of postsurgical neurological complications. In this study we evaluated complications in patients who underwent these interventions in general anesthesia, which demanded urgent consultations with a neurologist. The study comprised 120 patients. All patients underwent clinical neurological examination, electroencephalography (EEG) and, if required, computerized tomography (CT), performed by the same neurologist in all patients. The results of the study showed that in 96 patients (80%), clinical neurological examination revealed no focal signs, such as seizures or neurological deficits, except for qualitative alteration of consciousness of the confusion level. Nine patients (7.5%) had crisis of consciousness. Six patients (5%) had weakness in the right side extremities with motor dysp hasia that resolved within the first 24 hours - in this case EEG showed low intensity theta activity bilaterally above the frontoparietal regions. Six patients (5%) had hemipareses of moderate severity with CT-verified development of ischemic lesions. CT was performed in another six patients (5%) and revealed presence of mild brain edema. A positive correlation was found between the duration of anesthesia, patient's age and the presence of metabolic abnormalities, particularly diabetes mellitus. Our conclusions are that age, type of surgery and duration of anesthesia present the most significant factors for the development of neurological complications, whereas the presence of metabolic abnormalities and previous episodes of brain dysfunction increase the risk of these complications.
