Abstract
Objective To evaluate the efficacy of radiofrequency ablation performed under sevoflurane anesthesia in the pediatric patients with ventricular premature beats(VPBs). Methods Twenty American Society of Anesthesiologists physical status Ⅰor Ⅱ pediatric patients, with non-organic heart disease and VPBs, aged 3-12 yr, weighing 19-53 kg, undergoing elective radiofrequency ablation, were divided into propofol group(Pro group)and sevoflurane group(Sev group)using a random number table.Anesthesia was induced with midazolam 0.05 mg/kg, sufentanil 0.3-0.5 μg/kg, propofol 2.5-4.0 mg/kg(in Pro group)and 8% sevoflurane(in Sev group). Supreme laryngeal mask airway was placed when eyelash reflex disappeared.Propofol 6 mg·kg-1·h-1 was intravenously infused in Pro group, and 2%-3% sevoflurane was inhaled in Sev group, and bispectral index value was maintained at 50-60.The frequency of VPBs developed was recorded before induction and at 1, 5 and 10 min after induction, and the recurrence was observed within 1 month after operation. Results Compared with that before induction, the frequency of VPBs developed was significantly decreased at 1, 5 and 10 min after induction in Pro group(P 0.05). The frequency of VPBs developed was significantly higher at 1, 5 and 10 min after induction in Sev group than in Pro group(P<0.05). The recurrent rate was 30% within 1 month after operation in Pro group, no recurrence was found in Sev group, and there was significant difference between Sev group and Pro group(P<0.05). Conclusion The efficacy of radiofrequency ablation performed under sevoflurane anesthesia is better than that performed under propofol anesthesia in the pediatric patients with VPBs.
