OBJECTIVE: To evaluate the early and late effects of sevoflurane on the neonatal brain.
BACKGROUND: Sevoflurane is the most used anaesthetics in neonatal subjects.
METHODS: The study included 7-day-old male Wistar-Albino rats (n = 30), which were divided into the two groups according to the anaesthetic received: sevoflurane (S) and control group (C). Half of each group was sacrificed six hours after anaesthesia (early, E) while the remaining subjects were sacrificed six weeks later (late, L). The serum brain-derived-neurotrophic factor (BDNF), brain BDNF and caspase-3 were evaluated. In addition, elevated plus arm test and Morris water test were performed in the late group.
RESULTS: BDNF levels were higher in the late groups than in the early ones (p < 0.05).

BDNF levels in cerebral cortex were higher in the Group CE than in the Group CL and SL (p < 0.05). There was a significant negative correlation between serum BDNF and cortex BDNF levels (p = 0.003, r = –0.425). Cortex caspase 3 levels were significantly higher in the Groups SE and SL than in the Group CE and CL (p < 0.05). There was no significant difference between the groups in the terms of open arm index, locomotor activity and Morris water test.
CONCLUSIONS: Although sevoflurane induced apoptosis, it didn’t affect BDNF levels and showed no long-term negative effects on learning and anxiety in neonatal rats (Tab. 1, Fig. 3, Ref. 26).
