Pediatric anesthesia & critical care
Evaluation of the accuracy of oscillometric non-invasive blood pressure measurement at the ankle in children during general anesthesia
Authors' conclusion
We concluded that in pediatric population undergoing noncardiac surgery, ankle blood pressure was not interchangeable with the corresponding invasive readings with the ankle MAP having the least bias compared to SBP and DBP.
Study context
- Population
- Children undergoing noncardiac surgery under GA683 paired readings
- Participants
- 86 children
- Exposure
- Oscillometric ankle non-invasive BP vs radial invasive BP
- Outcome
- Mean bias and agreement between the two methods (Bland-Altman); ISO standard fulfilled if mean bias ≤ 5 ± 8 mmHg
Methodological detailsBland-Altman analysis, four-quadrant plot, ROC analysis
- Bland-Altman analysis
- Four-quadrant plot
- ROC analysis
Main finding
As reported in the abstract
Mean bias and agreement between ankle non-invasive and radial invasive BP (Bland-Altman)
Mean bias between the two methods, SBP (mmHg)
- 7.2 ± 10.7
Mean bias between the two methods, DBP (mmHg)
4.5 ± 12.8
Mean bias between the two methods, MAP (mmHg)
- 1.8 ± 8.2
Observational data: associations, not effects.
