- Abstract:
- Objective To summarize the application of bispectral index (BIS) during single-level selective dorsal rhizotomy (SL-SDR) for children with cerebral palsy (CP).Methods From March 2019 to March 2022,retrospective review was performed for 43 CP children undergoing SL-SDR.BIS was monitored during SL-SDR.They were divided into two groups of D (disturbance) and N (normal) according to the presence or absence of electromyographic disturbance.Gender,age,weight,type of CP,gross motor function classification system,mode of intravenous anesthesia,drug dose and dorsal root threshold ratio were recorded. At the same time,BIS values of group D from the beginning of electrophysiological stimulation to initial occurrence of electromyographic disturbance and group N from the beginning to the end of electrophysiological stimulation were compared.Results There were electromyographic disturbance (n=22) and non-disturbance (n=21).No significant inter-group differences existed in demographic characteristic,type of cerebral palsy,gross motor function classification system,anesthesia mode dosage or threshold ratio (P>0.05). The mean BIS value of group D (53.4±7.2) was significantly higher than that of group N (46.1±9.4)(t=11.889,P=0.007).According to the results of Logistic regression analysis,BIS value was an independent risk factor for electromyography disturbance in SL-SDR during intraoperative neurophysiological monitoring [OR=1.154,5%CI(1.035-1.287),P=0.01].Conclusion During SL-SDR neurophysiological monitoring,BIS value is an independent risk factor for electromyographic disturbance.And BIS ≥51 may be employed as an indicator for predicting the occurrence of electromyographic disturbance.
