The application of Bispectrai index in pediatric radio frequency catheter ablation / 中华全科医师杂志

ABSTRACT

The aim of the study is to evaluate the feasibility and safety of Bispectral index (BIS) monitoring in pediatric radio frequency catheter ablation. One hundred and six children aged 0. 6-12 years, scheduled for radio frequency catheter ablation, were randomly divided into two groups. In group A patients received BIS monitoring during the operation (n = 50), and the group B received modified Observer's Assessment of Alertness/Sedation (OAA/S) scaling (n = 56). The anesthesia was maintained with propofol target-controlled infusion. The intraoperative propefol target concentration was adjusted to maintain the BIS values between 55-65 in group A and OAA/S scale about 1 in group B respectively, The heart rate (HR), mean arterial pressure (MAP) and pulse oximetric saturation (SpO2) were measured before anesthetic induction, 1 min after induction, catheter puncturing and the end of operation respectively. The requirements of propofol, the times of supporting ventilation and recovery, the respiratory depression, nausea and vomiting postoperatively were also recorded. The intraoperative HR, MAP and SpO2 showed no differences between two groups, but the requirements of pmpofol, the times of supporting ventilation and recovery were less in group A than that of group B (P<0.05). All children didn't have nausea, vomiting and respiratory depression. The results suggest that in pediatric radio frequency catheter ablation, BIS monitoring has the advantages of timely adjustment of anesthetic depth, reducing anesthetic requirements, shortening the time of recovery, so as the perioperative safety can be improved.
