[Neurologic manifestations after surgical interventions]

Administration of general anesthesia is rarely accompanied with newly developed postoperative neurological complications. We analyzed postoperative complications after general anesthesia where an urgent neurologic assistance was necessary. The investigation included 120 patients. The same neurologist performed neurologic examination and electroencephalography, and computerized tomography (CT) was performed if necessary. In 96 (80%) patients focal stimulative or destructive phenomena such as epi-seizures or neurologic deficit were not detected by neurologic examination. In 9 (7.5%) patients were detected consciousness crisis. In 6 patients (5%) were registered right extremities weakness with motor dysphasia, which was withdrawn in first 24 hours. In these cases EEG revealed weak activity in theta frequency, above frontoparietal regions, bilaterally. In 6 (5%) patients was registered neurologic deficit of hemiparesis or semi-severe degree with development of ischemic lesion confirmed by CT. In 6 (5%) patients, CT scan revealed the presence of mild brain edema. Also, positive correlation between duration of anesthesia, age and metabolic disorders, specially diabetes mellitus, was found. We concluded that age, type of surgical intervention and duration of general anesthesia had the greatest influence on the development of neurologic disorders during and after general anesthesia, and the presence of metabolic disorders and previous brain damage increase the risk for the onset of these complications.
