Continuous non-invasive vs. invasive arterial blood pressure monitoring during neuroradiological procedure: a comparative, prospective, monocentric, observational study
Authors' conclusion
Nexfin is not strictly interchangeable with artery catheter for ABP measuring.
Study context
- Population
- Consecutive patients undergoing a neuroradiological procedure who needed an arterial catheter for BP measurement
- Participants
- 50 patients
- Exposure
- Nexfin vs radial artery catheter for arterial blood pressure (ABP) measurement
- Outcome
- Accuracy and clinical concordance of ABP (systolic, mean, diastolic) between devices (Bland-Altman and error grid analyses)
Methodological detailscomparative, monocentric
- Comparative
- Monocentric
Main finding
As reported in the abstract
Accuracy and clinical concordance (Nexfin vs artery catheter)
- Limits of agreement
- Bias (limits of agreement (LOA)), SAP 9.6 mmHg (CI - 15.6 to 34.8)
- Limits of agreement
- Bias (LOA), MAP - 0.8 mmHg (CI - 17.2 to 15.6)
- Accuracy and clinical concordance (Nexfin vs artery catheter)
- r2, SAP 0.78; P < 0.001
- Accuracy and clinical concordance (Nexfin vs artery catheter)
- r2, MAP 0.80; P < 0.001
- Nexfin measures in error grid risk zone A or B
- 99%
- Hypertension events not detected by Nexfin
- 65.7%
- Hypotensive events not detected by Nexfin
- 41%
Observational data: associations, not effects.
