Authors' conclusion

In pulsed-field ablation procedures for atrial fibrillation, remimazolam-ketamine DAS was superior to propofol-opioid regimens (either boluses or continuous) and had the lowest risk of hypoxemia and hypotensive events.

Study context

Population
Patients undergoing pulsed-field ablation (FARAPULSE) for AF; OSA excluded
Participants
127 patients
Comparison
Remimazolam-ketamine deep analgosedation (DAS) and propofol-opioid TIVA vs propofol-opioid DAS
  • Pn = 42reference
  • Rn = 43
  • TIVAn = 42
Primary endpoint
Composite of:
  • Hypoxemia
  • Hypotensive or hypertensive events requiring intervention or leading to procedure discontinuation
