No publication linked
No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
The relative increase in the mPAP with the same unit increase in MAP adjusted for baseline, and RV function assessed by GLS, between VP and NE in patients with normal and increased pulmonary artery pressure, who require vasopressor support during cardiac surgery.
