Background: Abnormalities in the neurosurgical field concerning cranial structure are almost always followed by increased intracranial pressure (ICP), which causes cerebral hypoxia and disrupts the whole cellular system. This study analyzes the correlation between ICP changes and oxidative stress markers, in subjects with various anatomical pathology abnormalities who underwent surgery.
Methods: This was a cross sectional study of 24 subjects with ICP conducted in the Department of Neurosurgery, Cipto Mangunkusumo Hospital, Jakarta, from November to December 2009. In this study, ANOVA analysis has been done to measure the mean difference oxidative stress (MnSOD, NADPH, MDA, and catalase) in subjects with various changes in ICP who have undergone surgery and Spearman analysis to measure the correlation between each oxidative stress markers. Oxidative stress markers were measured from normal brain tissue taken intra-operatively, cerebrospinal fluid (CSF) taken while doing ventriculostomy, and peripheral blood taken from a central vein catheter (CVC).
Results: The results showed that MDA concentrations in blood were significantly correlated with MDA in brain tissue (P = 0.029) in all of the ICP groups, CSF MnSOD concentration and CSF NADPH concentrations correlated with brain tissue NAPDH (p= 0.000) in congenital group and CSF catalase concentration correlated with brain tissue catalase (p = 0.00) in congenital group.
Conclusion: Increased ICP caused by various pathological conditions causes changes in oxidative stress markers in brain cells, CSF and blood. Oxidative stress markers in blood and CSF are correlated strongly with the brain. It is suggested that it could be used to predict intracranial high pressure in all cases with intracranial abnormalities.
