Implication

Validates microemboli detection in vitro; leaves open clinical utility during cardiopulmonary bypass.

Key Points

This research aims to evaluate two computerized methods for detecting gaseous microemboli in blood using pulsed Doppler ultrasound.
Utilized pulsed Doppler ultrasound and spectral analysis in a test rig to monitor blood flow.
Developed two ultrasound microemboli indices for detecting microembolic phenomena.
Assessed blood samples of agitated blood compared to normal blood using the methods.
Both indices showed significant increases in detection for agitated blood (p < 0.001).
Established a linear relationship between the methods (r = 0.91, p < 0.01).
Both techniques provided similar quantitative information on microemboli detection.

Structured PICO

Can computerised techniques analyzing pulsed Doppler ultrasound data detect gaseous microemboli in blood?

Population

Blood samples in a test rig (in vitro model)

Intervention

Two computerised techniques for detecting microemboli by analysis of Doppler blood velocity data (sonagram)

Comparator

Normal blood

Outcome

Detection of gaseous microemboli (ultrasound microemboli indices)surrogate

Computerised analysis of pulsed Doppler ultrasound signals can reliably detect gaseous microemboli in an in vitro blood flow model, with potential applications during cardiopulmonary bypass.
