Bilateral Transcranial Doppler Monitoring During Neonatal Cardiac Surgery; Guidance for Clinical and Scientific Use
Authors' conclusion
This study demonstrates that bilateral transcranial Doppler monitoring is feasible during neonatal cardiac surgery when performed within the recommended operational safety limits.
Study context
- Population
- Neonates undergoing cardiac surgery
- Participants
- 44 procedures
- Outcome
- Feasibility of continuous bilateral transcranial Doppler monitoring for assessing cerebral perfusion
Methodological detailsprospective, single-group
- Prospective
- Single-group
Main finding
As reported in the abstract
Feasibility (signal quality)
- Bilateral sufficient signal quality at the start
- all patients
- Unilateral signal deterioration, left MCA
- 1 (2.5%)
- Unilateral signal deterioration, right MCA
- 3 (7.5%)
Observational data: associations, not effects.
