Key result
Continuous cardiac output measurement catheter readings correlated significantly with conventional thermodilution values before abdominal aortic cross-clamping (r=0.941).
Why the study?
Does continuous cardiac output measurement (CCOM) accurately correlate with conventional thermodilution in patients undergoing abdominal aortic aneurysm surgery?
Observational (n=8)
No
Does continuous cardiac output measurement (CCOM) accurately correlate with conventional thermodilution in patients undergoing abdominal aortic aneurysm surgery?
Effect estimate: r=0.941
Continuous cardiac output monitoring correlates well with thermodilution during AAA surgery but requires positional adjustment and calibration during major hemodynamic shifts like aortic cross-clamping.
Should not yet change practice; leaves open prospective validation of CCOM in AAA surgery.

Ohnishi et al. (1995) conducted an observational in Abdominal aortic aneurysm (n=8). Continuous cardiac output measurement catheter (CCOM) vs. Conventional bolus thermodilution was evaluated on Correlation of cardiac output measurements before aortic cross-clamping (r=0.941). Continuous cardiac output measurement catheter readings correlated significantly with conventional thermodilution values before abdominal aortic cross-clamping (r=0.941).
