Intra-aortic balloon pumps (IABP) have saved many patients with cardiogenic shock during the perioperative period of cardiac surgery. However, the ideal insertion timing is controversial. In the present study, we aimed to optimize the insertion timing, in order to increase the survival rate of the patients. A total of 197 patients with cardiogenic shock(More)
We implement and characterize an optical narrowband amplifier based on stimulated Brillouin scattering with pump-to-signal relative frequency fluctuations overcome thanks to an active pump tracking. We achieve a precise characterization of this amplifier in terms of gain and noise degradation (noise figure). The performances of this stable selective(More)
The purpose of the study is to investigate the effectiveness of serum creatinine, the most common indicator of acute kidney injury (AKI), in predicting the prognosis of critically ill patients after cardiac surgery. Also, we sought to validate the use of this biomarker in assessing the direct outcome of a clinical setting. We selected 592 patients from our(More)
