This study provides an objective, intuitive, and easy to monitor method of brain function monitoring for the development of the neural monitoring model for stroke unit.
[method] the research group of this study was divided into early diagnosis group, dynamic trend change group, and the two groups were set up control group respectively.
Early diagnosis group: the study group included 38 patients with acute internal carotid artery system cerebral infarction (20 cases of focal cerebral infarction, 18 cases of large area cerebral infarction), 30 cases of normal EEG hospitalized patients (control group). In the study group and the recruited control group, the 8 channel central lead recording mode was adopted for routine EEG and RBP chemotaxis. The study group ensured that the bedside EEG examination was completed within 24 of the onset of the disease for at least 30 minutes each time. The changes in the cerebral area of the infarct site and the contralateral brain region, the occipital cerebral area of the infarct side and the lateral occipital region of the healthy side were compared and analyzed. The differences in the RBP difference between the focal cerebral infarction, the large area cerebral infarction and the normal control group were compared.
Dynamic trend change group: 30 cases of acute cerebral infarction in the middle cerebral artery blood supply area were included in this study group, and 30 patients in the same period were hospitalized (control group). The patients in the study group were monitored by bedside EEG within 48 hours, 5-6 days, and 10-11 days after the onset of the disease, and the general data, complications and laboratory results were recorded. After 48 hours of admission, 48 hours, 5-6 days and 10-11 days after admission, the patients were followed up for 1 months. According to the survival, the patients were divided into the survival group and the death group. The dynamic changes of the electroencephalogram (RBP) of the two groups of cerebral infarction patients in 48 hours after the onset, the 5-6 day, and the three stage 10-11 days at the 10-11 day were analyzed. Trends were further compared between the survival group, the death group and the control group with the difference in the trend of RBP.

Part one:
Compared with the contralateral brain area, the infarct area was asymmetrical on the RBP of the focal infarction group, the delta wave in the brain region of the lesion and the RBP of the theta wave were significantly increased (P0.01), the RBP of the alpha wave and the beta wave decreased significantly (P0.01). The distribution of RBP in the large area infarction group was also asymmetrical, and the delta wave RBP was significantly increased (P0) in the affected side of the cerebral area (P0). .01), the RBP of the alpha wave and beta wave decreased significantly (P0.01), but there was no significant difference between the two sides of theta wave RBP (P0.05). Compared with the control group, the infarct brain regions of the two groups of cerebral infarction were all delta wave, theta RBP increase (P0.01), alpha wave, RBP reduction (P0.01) of beta wave, and the change of occipital RBP: two groups of different area cerebral infarction patients, bilateral occipital bands RBP on each band Compared with the healthy lateral occipital region, the RBP value of the lateral occipital lobe was increased, the RBP of the alpha wave and the beta wave decreased (P0.05). Compared with the control group, the lateral occipital RBP in the healthy side showed delta wave, theta wave RBP increased, the RBP decreased (P0.05) in the alpha wave and beta wave, and there was no statistical difference between the delta wave, the alpha wave and the beta wave RBP in the focal group. Differences (P0.05).
The second part:
1, the infarct area RBP changes in 48h, 5-6 days, 10-11 days and three stages.
In the death group, the RBP values in the infarct brain region of the patients in the survival group were changed with time, and the change trend of the two groups was different (P0.05), while the RBP value of the four bands in the control group was not significantly changed in the three time monitoring (P0.05); the two group of cerebral infarction patients had 6 and three RBP values of theta wave, three time Duan Junxian. The RBP values of alpha and beta waves were significantly lower than those in the control group (P0.05). There was no significant difference in the value of delta, theta, alpha and beta wave RBP in the cerebral infarction area of the two groups of cerebral infarction (P0.05). The RBP value in the delta band of the dead group showed a continuous upward trend in the three monitoring of the delta band RBP value; the survival group showed a rising, then declining trend, only slightly higher than the 10 day. At the time of admission, the increase in the RBP value of the delta wave in the death group was much higher than that in the survival group at 5-6 days. The RBP value of the cerebral area in the infarct area of the dead group showed a continuous downward trend in the three monitoring. The survival group was first descended, and the middle and late monitoring had no obvious changes; there was no significant difference in the middle and late monitoring results between the two groups. The alpha band RBP value of the region showed a continuous downward trend in the three time monitoring. The RBP value of the alpha band in the survival group was basically maintained at the admission level within 1 weeks, and then gradually increased, but still did not recover to the normal level at 10 days. The overall trend of the RBP value in the alpha band of the death group was significantly lower than that in the survival group. The RBP value of the death group was first decreased during the period of hospitalization. The trend of mild recovery was still lower than the level of admission at 10 days. The RBP value of the survival group was basically maintained at the admission level in 1 weeks, and then the trend was gradually rising, and the overall trend of the RBP value in the beta band of the death group was significantly lower than that in the survival group.
2, the changes of RBP in 48h, 5-6 days, 10-11 days and three stages in the contralateral brain area.
In the death group, the RBP values of the infarct contralateral brain region in the infarct contralateral brain were changed with time, and there was a significant statistical difference between the two groups (P0.05), while the RBP values in the four bands of the control group were not significantly altered in the three time monitoring (P0.05), and the infarct to lateral brain area of the two cerebral infarction patients was Delta, 0 wave. The value of RBP in three time periods was significantly higher than that in the control group, and the RBP value of alpha and beta wave was significantly lower than that of the control group (P0.05). The delta wave RBP value of the infarct area in the death group was gradually rising, and the RBP value of the Delta wave in the lateral brain area of the survival group gradually increased in 6 days, and then gradually descended at 10 days, and then basically recovered to the level of admission. The overall trend of the 6 wave RBP value in the lateral brain region of the live group was much lower than that in the death group. The difference in the three monitoring was gradually increasing. The 0 wave RBP value of the 0 wave in the lateral brain area of the death group was gradually decreasing; the survival group, the 0 band RBP of the infarct to the lateral brain area was gradually decreased in 6 days, and the last two monitoring results were found. There was no significant difference. The overall trend of the E wave RBP value in the lateral brain area of the death group was much lower than that in the survival group. The change trend of the RBP value of the alpha wave in the lateral brain area of the death group was first decreased, and the 6-10 day was basically maintained at the lower level. The change trend of the alpha wave in the lateral brain area of the survival group was gradually decreased, then the 10-11 day was gradually rising, and the basic level of the infarction in the lateral brain area was gradually increased. The overall trend of the alpha wave RBP value in the lateral brain area of the death group was much lower than that in the survival group. The trend of the RBP value of the beta wave in the lateral brain area of the death group was gradually decreased to the lower value in the 5-6 day, but it was slightly lower at the 10-11 day, but still lower than the admission test value. The results of the third monitoring were higher than the level of admission. The two groups were at the same level when they were admitted to the hospital. The decline of the death group was much larger than that of the survival group, which was lower to the lower level, and there was still no significant recovery at 10-11 days.
3, paired comparisons of infarcted brain areas and contralateral brain regions.
The RBP values in the bilateral brain regions of both the death group and the survival group had a tendency to change with the measured time period, and the changes in the four bands of the death group were inconsistent in the bilateral brain regions; the survival group was 6, the changes of the bilateral brain regions in the alpha and beta bands were inconsistent, and the change trend in the 0 band was not yet possible. There was a statistical difference between the two sides of the two groups. The levels of bilateral brain regions in the four bands of the two groups were asymmetrical. The three periods of alpha and beta wave in the infarct brain region were significantly lower than those in the contralateral brain, and the RBP value of the delta wave was significantly higher than that in the contralateral brain, and the bilateral asymmetry of the alpha wave in the death group was gradually increased. At the time of admission, the RBP value of the infarct brain area was higher than the contralateral side, and the 0 band RBP values of the bilateral brain regions were decreased in two times. The decrease in infarct brain area was much larger than that in the contralateral side. The infarct brain area was significantly lower than that in the contralateral brain area in the middle and late stage. The 0 band of bilateral brain area in the survival group was basically symmetrical when the survival group was hospitalized. In the middle and later stages of monitoring, the 0 band RBP values in the infarcted side were significantly lower than those in the contralateral side.
[conclusion]:1, electroencephalogram RBP has the early side significance for acute cerebral infarction in the acute internal carotid artery system of CT, and combined with the changes of RBP in the occipital region, it can identify the large area cerebral infarction.2, acute large area cerebral artery blood supply area infarcted brain area, and the alpha, beta, theta and delta RBP values in the lateral brain area are monitored during the hospitalization. The trend of the change of the time segment of the patient was significantly different in the RBP changes during the 1 months of hospitalization. The dynamic monitoring of the RBP trend in patients with severe hemispheric infarction can reflect the changes in the brain function in time, which is of great value for assessing the condition and the chance of survival at one month.
