The dynamic relationship between end-tidal sevoflurane concentrations, bispectral index, and cerebral state index in children.
BACKGROUND To guide anesthetic administration with electroencephalogram monitors in children, an adequate characterization of the anesthetic effect measured by these monitors in this population is needed. We sought to quantify and compare the dynamic profile of sevoflurane's effect measured with the cerebral state index (CSI) and the bispectral index (BIS) in children. METHODS Fifteen healthy...
متن کاملCorrelation of bispectral index with end-tidal sevoflurane concentration and age in infants and children.
BACKGROUND The bispectral index (BIS) has been evaluated as a tool for measuring depth of anaesthesia, but the use of BIS in a paediatric population is still controversial. This study was designed to evaluate the correlation of BIS with end-tidal sevoflurane concentration and age in infants and children. METHODS Eighty-one patients undergoing elective urology surgery were allocated into three...
متن کاملThe Effect of Different End-tidal Desflurane Concentrations on Bispectral Index Values in Normal Children and Children with Cerebral Palsy.
OBJECTIVE In this study, we aimed to compare the effects of different intraoperative end-tidal desflurane concentrations on bispectral index (BIS) values in normal children and children with cerebral palsy. METHODS Twenty normal children (Group N) and 20 children with non-communicative/nonverbal cerebral palsy (Group CP), between 2 and 15 years of age, undergoing elective orthopaedic surgery ...
متن کاملApplying a physiological model to quantify the delay between changes in end-expired concentrations of sevoflurane and bispectral index.
BACKGROUND The delay between changes in end-expired sevoflurane concentrations and bispectral index (BIS) may be characterized by a 'rate constant' (ke0). A smaller ke0 reflects a longer delay. Values for ke0 vary substantially among studies. The question arises how ke0 depends on experimental conditions, including ventilation and apparatus. METHODS Increasing and decreasing sevoflurane conce...
متن کاملCorrelation of bispectral index (BIS) monitoring and end-tidal sevoflurane concentration in a patient with lobar holoprosencephaly.
OBJECTIVE The bispectral index (BIS) is a parameter derived by electroencephalography (EEG) which provides a direct measurement of the effects of sedatives and anesthetics on the brain and offers guidance on the adequacy of anesthesia. The literature lacks studies on BIS monitoring in pediatric patients with congenital brain disease undergoing general anesthesia. CLINICAL FEATURES A 13-year-o...
