Effect of Sufentanil Combined with Dexmedetomidine on Hemodynamic and Narcotrend Index During Pediatric Anesthesia Induction / 医药导报

ABSTRACT

Objective To investigate the effect of different doses of sufentanil combined with dexmedetomidine ( DEX) on hemodynamic and Narcotrend index ( NI) during pediatric anesthesia induction. Methods A total of 45 children with lower abdominal surgery were randomly divided into three groups evenly: sufentanil 0. 1 μg·kg-1+ DEX (S1 group),sufentanil 0. 2 μg·kg-1+DEX (S2 group),and sufentanil 0. 3μg·kg-1+DEX (S3 group). Patients in each group began with intubation at the peak point of administration. Blood pressure,heart rate,perfusion index (PI) and NI were detected at the baseline (t0), delivering DEX 0.5 μg·kg-1·h-1 and sufentanil intravenously for 5 min (t1),delivering sufentanil for 3 min (t2),time of intubation ( t3 ) ,1 min ( t4 ) ,and 5 min ( t5 ) after intubation. The application rate of atropine and propofol was recorded. Patient recovery time and adverse reactions were observed. Results Compared with basicline value at t0 time point, hemodynamic parameters and NI were decreased at t1 and t2 ,while PI was increased in both groups. At t3 ,t4 ,and t5 ,all of the indicators in S1 group were significantly different from those at t0 ,and also significantly different from those in S2 and S3 group. Six patients were treated with propofol in S1 group and four presented with agitation after operation,more than S2 and S3 groups. Three patients were treatment with atropine in S3 group. Conclusion Sufentanil (0. 2 μg·kg-1 ) combined with dexmedetomidine can be used to induce intubation for pediatric anesthesia with stable hemodynamic profile and low incidence of adverse effects.
