Combined monitoring of intracranial pressure and bispectral index in patients with severe craniocerebral trauma post-operatively

Abstract

ObjectiveTo investigate the value of simultaneous bispectral index (BIS) and intracranial pressure (ICP) monitoring to evaluate postoperative consciousness and short-term prognosis in patients with severe traumatic brain injury. MethodsWe evaluated 30 brain trauma coma patients in the People’s Hospital of Northern Jiangsu Province from January 2014 to December 2014 and evaluated Glasgow Coma Scale (GCS) scores at 8-h intervals for 3days after surgery. BIS and ICP values were recorded at the same time. Based on the GCS score, patients were divided into two groups: group A (GCS score 3–≤5) and group B (>5–≤8). Natural survival rates were analyzed statistically and compared between groups. ResultsChi-square testing revealed a significant difference in survival rates between the groups (P<0.05). Spearman’s rank correlation analysis revealed that BIS value was positively correlated with coma degree post-operatively in patients with severe traumatic brain injury, and negatively correlated with ICP values (r=0.532, P<0.05; r=0.521, P<0.05, respectively). ConclusionIn patients with severe craniocerebral injury, higher severity, higher ICP, and lower BIS were associated with a worse prognosis. Combined monitoring of BIS and ICP is very useful when evaluating the coma degree and prognosis of patients with severe craniocerebral injury post-operatively.
