Comparison of two cardiac output monitors, qCO and LiDCO, during general anesthesia [PDF]

, 2016
Background: Optimization of cardiac output (CO) has been evidenced to reduce postoperative complications and to expedite the recovery. Likewise, CO and other dynamic cardiac parameters can describe the systemic blood flow and tissue oxygenation state and

Mapping the hemodynamic effects of terlipressin in patients with hepatorenal syndrome using advanced magnetic resonance imaging

JHEP Reports
Background & aims: Terlipressin improves renal function in ∼40% of patients with hepatorenal syndrome–acute kidney injury (HRS-AKI). Nonetheless, the pathophysiological mechanisms of terlipressin remain unclear.

Hemodialysis Patients with High-Flow Arteriovenous Fistulas: An Evaluation of the Impact on Cardiac Function

Vascular Specialist International
Purpose: Patients undergoing hemodialysis often experience changes in cardiac function when they have a high-flow arteriovenous fistula (AVF). This study aimed to assess the effect of high-flow AVFs on cardiac function in patients undergoing hemodialysis.

The Methodology of Doppler-Derived Central Blood Flow Measurements in Newborn Infants

International Journal of Pediatrics, 2012
Central blood flow (CBF) measurements are measurements in and around the heart. It incorporates cardiac output, but also measurements of cardiac input and assessment of intra- and extracardiac shunts.
