Reliability of Noninvasive Blood Pressure Monitoring During Atrial Fibrillation Ablation Under General Anesthesia
Authors' conclusion
While rhythm did not significantly alter NIBP reliability, substantial variability-particularly in systolic measurements-limits its interchangeability with IBP during AF ablation.
Study context
- Population
- Adults undergoing endovascular atrial fibrillation (AF) ablation under GA, tertiary academic medical center, June 2022–March 20231,158 paired measurements
- Participants
- 90 adults
- Exposure
- Noninvasive vs invasive BP monitoring
- Outcome
- Bias of NIBP vs IBP
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
- Noninvasive blood pressure (NIBP) underestimated SBP (all p < 0.05)
- 3.5 mmHg
- NIBP overestimated diastolic BP (all p < 0.05)
- 2.3 mmHg
- NIBP overestimated MAP (all p < 0.05)
- 1.4 mmHg
- Within-subject variability highest for SBP (SD)
- 12.3 mmHg
- Intraclass correlation coefficients across BP types
- 0.73 to 0.84
Observational data: associations, not effects.
Further findings
Effect of cardiac rhythm on agreement
- Cardiac rhythm did not significantly affect agreement; AF and paced rhythm associated with increased systolic error in univariate models
Other influences on discrepancies
- Ventilation mode and vasopressor use also influenced discrepancies
