Abstract:
Objective To analyze the differences and feasibility of non-invasive intracranial pressure monitoring and invasive intracranial pressure monitoring in patients with subarachnoid hemorrhage (SAH) at early stage,an explore the correlation of intracranial pressure and scores of Glasgow Coma Scale (GCS) with digital electroencephalogram data (cerebral state index [CSI],eleetromyographic [EMG]) obtained by cerebral state monitoring (CSM).Methods Synchronous line of 33 parents with SAH,having 3-12 GCS scores,was chosen in our study; early invasive intracranial pressure monitoring (lumbar puncture manometry/ventricular drainage manometry) and non-invasive intracranial pressure monitoring (flash visual evoked potential [F-VEP] monitoring),and brain function condition monitoring (CSI and EMG) were performed on these patients; the difference of non-invasive and invasive monitoring and the correlation of intracranial pressure with these indicators were analyzed.Results Non-invasive and invasive intracranial pressure monitoring results showed no significant difference in patients with SAH(t=-0.069,P=0.946; t=-0.158,P=0.876).The intracranial pressure was negatively correlated with CSI (r=-0.898,P=0.000) and positively correlated with EMG (r=0.938,P=0.000); GCS scores showed positive correlation with CSI (r=0.472,P=0.011) and showed no relation with intracranial pressure and EMG (r=-0.047,P=0.814; r=-0.170,P=0.388).In addition,after intracranial pressure being controlled and GCS scores being adjusted,partial correlation analysis indicated that CSI and EMG had no correlation (r=0.288,P=0.138).Conclusion Spontaneous F-VEP monitoring results have a high correlation with the results of lumbar puncture manometry and ventricular drainage manometry; intracranial pressure has correlation with CSI and EMG; dynamic intracranial pressure monitor trends are consistent with the changes of disease condition.
