Extracorporeal blood purification is associated with improvement in biochemical and clinical variables in the critically-ill COVID-19 patients.

This study tried to investigate the impact of oXiris filter on both clinical and laboratory parameters in critically-ill COVID-19 intensive care unit (ICU) patients receiving extracorporeal blood purification and the clinical setting for the initiation of therapy. A consecutive sample of 15 ICU patients with COVID-19 was treated with oXiris membrane for blood purification or for support of renal function due to acute kidney injury. We have included 19 non treated ICU COVID-19 patients as a control group.

Diagnostic accuracy of central venous saturation in estimating mixed venous saturation is proportional to cardiac performance among cardiac surgical patients.

Purpose: Advanced hemodynamic monitoring in cardiac surgery translates into improvement in outcomes. We evaluated the relationship between central venous (ScvO2) and mixed venous (SvO2) saturations over the early postoperative period. The adequacy of their interchangeability was tested in patients with varying degrees of cardiac performance.

The relationship between prolonged cerebral oxygen desaturation and postoperative outcome in patients undergoing coronary artery bypass grafting.

58 patients who underwent on-pump coronary artery bypass graft surgery were evaluated for changes in regional cerebral oxygen saturation (rSO2) measured by near infrared spectroscopy (NIRS). If rSO2 during the operation fell to more than 20% under the baseline, standardized interventions were undertaken to maintain rSO2. Despite those interventions, in some cases we observed inability to maintain rSO2 above this threshold.

Reduction of microembolic signals with a single-clamp strategy in coronary artery bypass surgery: a pilot study.

Background: Neurologic deficits are perhaps the most feared form of adverse outcome following cardiac surgery. Aortic trauma generates emboli and hence harbors the potential for neurocognitive injury. The single aortic clamp strategy of coronary artery bypass grafting (CABG) aims at reducing aortic manipulation.

NT-pro-BNP, but not C-reactive protein, is predictive of atrial fibrillation in patients undergoing coronary artery bypass surgery.

Objective: Atrial fibrillation (AF) remains the most commonly observed complication following myocardial revascularisation surgery. We aimed to evaluate the clinical utility of N-terminal fragment of the brain natriuretic peptide (NT-pro-BNP), troponin T, transcoronary lactate gradient (TCLG) and C-reactive protein (CRP) as predictors of AF in patients undergoing isolated coronary artery bypass surgery (CABG).

Methods: This study included 215 consecutive patients in sinus rhythm (SR) undergoing elective CABG between May 2007 and May 2008.
