Abstract: Objective To investigate changes in serum neuron-specific enolase (NSE) concentration in patients before,during and after surgery for acute craniocerebral trauma,and examine the effects of propofol and isoflurane on these changes. Methods Ten patients scheduled for urinary operation without cerebral injury were enrolled in the control group.Thirty patients with acute cerebral trauma were randomly allocated to propofol group (n=15) and isoflurane group (n=15).Serum concentrations of NSE before surgery,2 h after the surgery began,and after completion of surgery were measured in all the patients by enzyme-linked immunoadsorbent assay.Glasgow scores of patients with cerebral trauma were also estimated and recorded. Results Serum concentration of NSE in patients with cerebral trauma were significantly higher than those in the control group before the surgery (P<0.01).The Glasgow score was inversely correlated with serum NSE concentration (r=-0.494,P<0.01).Serum NSE level after completion of surgery was significantly lower in propofol group than in isoflurane group (P<0.05).NSE levels at 2 h after the initiation of the surgery and after the completion of surgery were higher than those before the surgery. Conclusions Serum NSE concentration increases in patients with acute cerebral injury in parallel to the severity of brain damage.Application of propofol by intravenous pumping can reduce the increase in serum NSE,alleviate cerebral injury,and protect the brain tissues of patients undergoing surgery for acute craniocerebral trauma.
