Pediatric anesthesia & critical care
A prospective comparison of invasive and non‐invasive blood pressure in children undergoing cardiac catheterization
Authors' conclusion
Automated oscillometric blood pressure measurement is unreliable in anesthetized children during cardiac catheterization.
Study context
- Population
- Children under 16 years undergoing cardiac catheterization with GA, 3 pediatric hospitals683 paired BP values
- Participants
- 254 participants
- Exposure
- Non-invasive vs invasive BP measurement
- Outcome
- Agreement of MAP measurements (bias >5 mmHg and SD >8 mmHg clinically significant)
Methodological detailsmulticentre, Bland-Altman analysis
- Multicentre
- Bland-Altman analysis
Main finding
As reported in the abstract
Agreement of MAP measurements (Bland-Altman bias, non-invasive vs invasive)
Overall bias (SD) for mean arterial pressure (MAP) values, mmHg
7.2
11.4
Observational data: associations, not effects.
Further findings
Agreement of MAP during hypotension (190 readings)
- Bias (SD) during hypotension, mmHg
- 15 (11.0)
Agreement by age
- Non-invasive MAP frequently higher than invasive MAP during infancy, and lower in older children
