Abstract:
Objective To determine the brain protective effects of inhalation anesthetic pretreatment in infants undergoing open-heart surgery under extracorporeal circulation (ECC).Methods Forty-five infants (no more than 3 years old) with congenital heart diseases who received surgical treatment were divided into 3 groups by table of random digit,sevoflurane pretreatment group (group S,15 cases),isoflurane pretreatment group (group Ⅰ,15 cases) and control group (group C,15 cases).In pretreatment group,all infants had been inhaled 1.0-1.5 MAC sevoflurane or isoflurane continually for over 60 min after intubation,while group C did not receive pretreatment.Blood samples were taken before (T1) and in 5 min after ECC (T2),occlusion of aorta (T3),30 min after ECC (T4),end ofECC (T4),and 6 and 24 h after the end of ECC (T6 and T7).Serum levels of S 100 β protein and neurone specific enolase (NSE) were measured by enzyme-linked immunosorbent assay.Results There was no significant difference in the serum levels of S100β protein and NSE among the 3 groups in T1 (P＞0.05).There was no significant difference in the serum levels of S100β protein and NSE in group S and group Ⅰ between T1 and T2-7 (P＞ 0.05).There was no significant difference in the serum levels of S100 β protein and NSE in T2-7 between group S and group Ⅰ (P ＞ 0.05).In group C,there were significant differences in the serum levels of S100 β protein in T4-6 and NSE in T4-7 than those in T1 (P＜ 0.05).In T4-6,the serum levels of S100 β protein and NSE in group S and group Ⅰ were significantly lower than those in group C [S100 β protein:(0.45 ± 0.31),(0.47 ± 0.35) μ g/L vs.(0.73 ± 0.31) μ g/L,(0.53 ± 0.33),(0.54 ± 0.36) μ g/L vs.(0.91 ± 0.30) μ g/L,(0.47 ± 0.34),(0.49 ±0.35) μ g/L vs.(0.79 ± 0.40) μ g/L,P ＜ 0.05； NSE:(3.26 ± 1.34),(3.32 ± 1.34) μ g/L vs.(7.20 ± 2.71)μ g/L,(5.57 ± 1.49),(5.61 ± 1.52) μ g/L vs.(7.68 ± 3.68) μ g/L,(2.29 ± 1.21),(2.34 ± 1.22) μ g/L vs.(9.46 ± 4.61) μg/L,P ＜ 0.05].Conclusion Sevoflurane or isoflurane pretreatment significantly decreases the serum levels of S100 β protein and NSE during open-heart operation in infants with ECC.
