Abstract
Objective To explore the anaesthetic effects and evoked electromyogram results of different doses of dexmedetomidine in the surgery of selective posterior lumbar rhizotomy for the treatment of mixed dystonia and spasticity in children with cerebral palsy.Methods There were 60 cases of mixed dystonia and spasticity children with cerebral palsy underwent selective posterior lumbar rhizotomy from February 2015 to March 2016 in our hospital.According to random number table,all the 60 cases were divided into two groups,with 30 cases for each.Two groups of children were given electrophysiological monitoring during operation,in which group A was given 0.5 μg/(kg · min) dexmedetomidine by intravenous infusion,and group B was given 1.0 μg/(kg · min).It was compared respectively between the two groups of operation time,anesthesia time,waking hours,EEMG latency and amplitude of retention rate,mean arterial pressure,heart rate,SpO2 and adverse reactions.Results There was no difference of operation time,anesthesia time and the waking hours (P ＞ 0.05).There was no difference of the EEMG latency and amplitude of retention rate before and after the dexmedetomidine injection between the two groups (P ＞ 0.05).The mean arterial pressure and heart rates of group B was (60.5 ± 5.1) mmHg and (72.3 ± 10.1) times/minute respectively,which were significantly lower than (63.8 ±6.6) mmHg and (80.6-± 12.5) times/min of group A.The differences were statistically significant (all P ＜ 0.05).There was no significant difference of the incidence of adverse reactions between the two groups (P ＞ 0.05).Conclusions It may be the better dose of 0.5 μg/(kg · min) of dexmedetomidine in elective posterior lumbar rhizotomy for the treatment of mixed dystonia and spasticity in children with cerebral palsy for more advantages of safety and efficacy.关键词
