Sažetak
Background and Goal of Study: S100B protein and NSE (neuron specific enolase) can be considered as early markers of cerebral injury. The impact of general anesthesia for elective noncardiac surgery in children on these markers has not been studied before. The goal was to find out whether these markers can be used to access the short term neurological outcome after general anesthesia. The secondary goal was to determine whether different types of anesthesia influence the levels of S100B and NSE. Materials and methods: Prospective study was conducted at the University Hospital on 64 children (aged 6-12, ASA I-II) undergoing elective adenotonsillectomy. The children were randomized into 2 groups:TIVA (n=32) and sevoflurane(S) (n=32). In TIVA group anesthesia was induced with propofol, fentanyl and vecuronium and maintained with continuous infusion of propofol. In S group, anesthesia was induced with fentanyl, sevoflurane and vecuronium and maintained with sevoflurane. S100B and NSE were measured before and after the surgery. S100B and NSE assays were performed using the electrochemiluminiscence immunoassay “ECLIA” used on Roche Cobas e601 immunoassay analyzer (Roche Diagnostics GmbH, Mannheim, Germany). Statistical significance of the differences was accessed by two-tailed asymptotic Wilcoxon Signed Rank test. The 95% CI for median difference was calculated by bootstrapping on 1000 samples in IBM SPSS Statistics version 21. Results and discussion: There was statistically significant increase of S100B median value after surgery with regard to preoperative values (P< 0.001). Median(interquartile range) values of S100B before and after surgery were 0.08 (0.064-0.102) and 0.1 (0.072-0.179), respectively. There was no statistically significant change of NSE median value af ter surgery regarding preoperative values (P=0.567). The prevalence of elevated S100B (≥0.105 ug/l) after the surgery was statistically significantly higher than before (McNemar test, two sided exact P=0.003). There were 12/60 children (20.0% ; 95% CI=(10.5%-29.8%)) with elevated S100 B before and 28/60 (46.7% ; 95% CI=33.3%-59.6%)) after surgery. Conclusion(s): The values of neurological biomarker S100B, but not of NSE, were significantly increased af ter general anesthesia for elective adenotonsillectomy in children, indicating possible cerebral injury.There were no differences regarding 2 types of anaesthesia, TIVA or inhalational.
