We investigated correlations between hemolysis index (HI) and plasma-free hemoglobin (PFH) levels on one hand, and between the HI and plasma lactate dehydrogenase (LDH) levels on the other, in critically ill patients with and without extracorporeal or mechanical circulatory support.

Jan 19, 2022 · the scientific reach and capability of the Green Bank Telescope (GBT) and the Very Long Baseline Array (VLBA). The experimental effort installed an RI&S Ku-Band transmitter on the GBT and relied on VLBA receiving stations to receive the data transmission. That transmission generated synthetic

Nov 15, 2022 · A hemolytic component derived from the four conventional hemolytic markers (AST, LDH, bilirubin, reticulocyte percentage) was significantly associated with PFH (R=0.573, p<0.001). The best performing hemolytic component derived from just two variables, AST and LDH, correlated with PFH (R=0.637, p<0.001)

Plasma-free hemoglobin (PFH) levels greater than 15–50 mg/dL are most commonly caused by the shear stress and pressure drop regularly experienced during ECLS (1–6). As a result, the PFH may increase 10- to 25-fold during ECLS.

Patients supported with extracorporeal membrane oxygenation (ECMO) or short-term centrifugal ventricular assist devices (VADs) are at risk for potential elevation of plasma-free hemoglobin (pfHb) during treatment. The use of pfHb testing allows detection of subclinical events with avoidance of propagating injury.

We present three cases of severely elevated plasma free hemoglobin (PFH) in pediatric patients on mechanical circulatory support devices at a tertiary pediatric care center.

May 2, 2024 · Plasma free hemoglobin (PFH) is a direct biomarker for hemolysis that has been associated with clinical complications such as pulmonary hypertension and death in patients with sickle cell disease (SCD).

Mar 23, 2024 · We investigated correlations between hemolysis index (HI) and plasma-free hemoglobin (PFH) levels on one hand, and between the HI and plasma lactate dehydrogenase (LDH) levels on the other, in critically ill patients with and without extracorporeal or mechanical circulatory support.

Blood passage through medical devices can cause hemolysis and increased levels of plasma free hemoglobin (pfH) that may lead to adverse effects such as vasoconstriction and renal tubule injury.

Feb 19, 2025 · Plasma free hemoglobin (PFH) is a direct biomarker for hemolysis that has been associated with clinical complications such as pulmonary hypertension and death in patients with sickle cell disease (SCD).
