Veno-venous arterial extracorporeal membrane oxygenation is a hybrid-modality of extracorporeal membrane oxygenation combining veno-venous and veno-arterial extracorporeal membrane oxygenation. It may be applied to patients with both respiratory and cardio-circulatory failure. ⋯ Our computational spreadsheet identifies the suitable cannula pairing set for correctly splitting the outlet blood flow into the arterial and venous return cannulas in a veno-venous arterial extracorporeal membrane oxygenation configuration without the use of external throttles. Several limitations were reported regarding fixed aortic impedance, central venous pressure and the types of cannulas tested; therefore, further studies are mandatory to confirm our findings.

Anticoagulation is used to prevent filter clotting in patients undergoing continuous renal replacement therapy. Regional citrate anticoagulation is associated with lower rates of bleeding complications and prolongs the filter life span; however, a number of metabolic side effects had been associated with this therapy. The aim of this study was to evaluate the effect and safety of citrate versus heparin anticoagulation for continuous renal replacement therapy in critically ill children. ⋯ Our study showed that citrate is superior in terms of safety and efficacy, with longer filter life span. Regional citrate should be considered as a better anticoagulation method than heparin for continuous renal replacement therapy in critically ill children.

Cardiogenic shock is associated with significant mortality, morbidity, and healthcare cost. Utilization of extracorporeal membrane oxygenation in cardiogenic shock has increased in the United States. We sought to identify the rates and predictors of hospital readmissions in patients with cardiogenic shock after weaning from extracorporeal membrane oxygenation. ⋯ Patients with cardiogenic shock who underwent extracorporeal membrane oxygenation had a readmission rate. Identifying patients at high risk of readmissions might help improve outcomes.

In vitro performance verification of ventricular assist devices using a mock circulatory loop is a prominent step to guarantee the system responses and the device performance and safety before the in vivo tests and ultimately clinical trials. ⋯ To date, all left ventricular assist devices made in China have been evaluated according this protocol and some of them have entered the clinical trial stage. We are closely observing the clinical data in order to further improve the performance of the platform and encourage more advances in mechanical circulatory assist devices.

This study aimed to evaluate the clinical effects of hemoperfusion plus continuous veno-venous hemofiltration in the treatment of patients with multiple organ failure after wasp stings and investigate its impacts on cytokines. ⋯ Our results revealed that hemoperfusion plus continuous veno-venous hemofiltration was effective in the management of patients with multiple organ failure after wasp sting via the non-specific removal of the wasp venom and inflammatory cytokines.
