A retrospective pediatric ablation study found no significant inducibility difference among three anesthetic groups. Remimazolam’s higher BIS readings did not establish lesser clinical anesthesia.
The investigators analyzed 173 children undergoing radiofrequency ablation for supraventricular tachycardia. Groups were defined by use of propofol, ciprofol, or remimazolam. Arrhythmia inducibility was approximately 94%–97% across groups and did not differ significantly.
Ablation success and several other procedural measures were also similar. Remimazolam recipients had higher intraoperative BIS values and shorter extubation times in the reported comparison.
The anesthetic choice and dose were selected clinically rather than standardized prospectively. There was no exact common BIS target maintained across the historical groups. The authors also noted that BIS may not reflect remimazolam depth in the same way as other agents.
Single-center selection, treatment decisions, and retrospective documentation constrain causal inference. Nonsignificant inducibility results are not formal proof of equivalence for every electrophysiologic procedure.
An isolated processed-EEG number should be interpreted with drug, dose, clinical response, and procedure. This study cannot establish awareness from a higher BIS reading or demonstrate that the sedative caused an individual ablation success or failure.
