- Abstract:
- Objective To explore the correlation between cerebral state index (CSI) and bispectral index (BIS) in the monitoring of radiofrequency ablation anesthesia in children and evaluate the feasibility of CSI for pediatric monitoring.Methods Thirty-six children aged 7 to 15 years,ASA Ⅰ to Ⅱ,were scheduled for arrhythmic radiofrequency ablation under general anesthesia.Propofol 2.5 mg/kg,cis-atracurium 0.1 mg/kg and fentanyl 1 μg/kg were administered for induction.For anesthetic maintenance,a continuous intravenous infusion of propofol was used for maintaining a BIS level of 60 to 70 by a closed-loop mode machine.Remifentanil was continuously infused at a rate of 0.25 to 0.33 μg.kg-1.min-1 for maintaining stable hemodynamics.CSI and BIS were recorded at the timepoints of entering operating room (T1),completing tracheal induction (T2),operation starting (T3),30 min (T4),60 min (T5),90 min (T6),intravenous infusion stopping (T7),extubation (T8) and leaving operating room (T9).The modified awake sedation scores (MOAA/S) were recorded at T7 to T9.Results The Spearman’s correlation coefficients of CSI and BIS were 0.87,0.84 and 0.69 respectively for T1 to T2 induction period,T3 to T6 maintenance period and T7 to T9 recovery period (P<0.05).CSI was lower than BIS at T1,T3 to T5 (P<0.05) and was higher than BIS at T8 to T9 (P<0.05).No significant difference existed in CSI and BIS at T2,T6 and T7 (P>0.05).From T7 to T9,the Spearman’s correlation coefficient of CSI and MOAA/S and BIS and MOAA/S were 0.77 and 0.75 respectively (P<0.05).Conclusion CSI and BIS have an excellent correlation.And CSI may be used for monitoring the depth of anesthesia during intravenous anesthesia in children.
