Venoarterial extracorporeal membrane oxygenation flow or dobutamine to improve microcirculation during ECMO for refractory cardiogenic shock.
Venoarterial extracorporeal membrane oxygenation (VA ECMO) effectively supports refractory cardiogenic shock (rCS), and sustains macro- and microcirculations. We investigated the respective impact of increasing VA ECMO flow or dobutamine dose on microcirculation in stabilized VA ECMO-treated patients with rCS. ⋯ When macrocirculation has already been restored in patients with ECMO-supported rCS, increasing dobutamine (above 5 μg/kg/min) or ECMO flow did not further improve microcirculation.

Association of blood pressure variability with short- and long-term cognitive outcomes in patients with critical illness.
Blood pressure variability (BPV), a modifiable risk factor, can compromise cerebral perfusion in critically ill patients. We studied the association between BPV in the intensive care unit (ICU) and short- and long-term cognitive outcomes. ⋯ BPV was associated with increased likelihood of delirium in the ICU. Delirium, but not BPV, was associated with long-term cognitive decline.

Clinicians' Views on the use of triggers for specialist palliative care in the ICU: A qualitative secondary analysis.
To understand clinicians' views regarding use of clinical criteria, or triggers, for specialist palliative care consultation in the ICU. ⋯ ICU and palliative care clinicians identified important issues to consider when implementing triggers for specialist palliative care consultation. Future research is needed to longitudinally examine the most appropriate triggers and best practices for trigger implementation.

Red blood cell distribution width as prognostic factor in sepsis: A new use for a classical parameter.
To evaluate Red blood cell distribution width (RDW) as a sepsis prognostic biomarker. ⋯ RDW is an independent prognostic marker of death in septic patients admitted in the ICU that improves SOFA, LODS, APACHE-II and SAPS-II discrimination ability. This parameter could be incorporated to the prognostic scores as a marker of systemic dysfunction and dysregulated inflammatory response.

Characterising acute kidney injury: The complementary roles of biomarkers of renal stress and renal function.
Although epidemiological studies have enhanced our understanding of acute kidney injury, defining the biologic processes corresponding to the clinical phenotype remains challenging. We have examined biomarkers associated with renal stress plus markers of glomerular function to assess whether this approach may aid prediction of AKI or other relevant endpoints. ⋯ The combination of cell-cycle arrest biomarkers, TIMP-2 and IGFBP7, with serum creatinine but not cystatin C or PENK improved risk stratification for the development of stage 2 or 3 AKI over [TIMP-2]·[IGFBP7] alone.
