Dialysis patients have reduced walking capacity and an important risk of high blood pressure. These complications are associated with a decline in quality of life and increased mortality. The hypothesis of the study is to show that physical activity during the dialysis session in dialyzed patients has a benefit on quality of life, as well as on muscle, cardiovascular and dialysis parameters.

ARDS is a pulmonary edema injury. Among its etiologies, it can be secondary to septic shock. Managing septic shock involves hemodynamic optimization with significant fluid and sodium inputs. Fluid and sodium inputs in ARDS worsen respiratory failure through capillary leakage, and a restrictive input strategy is clinically beneficial (reduced mechanical ventilation duration and ICU stay). Predicting ARDS onset in septic shock allows for optimized fluid and sodium input management, adopting a restrictive rather than liberal approach to minimize deterioration in respiratory function.

Several data emphasize the relation between tachycardia (>90/min) and high mortality during septic shock. The investigators previously demonstrated the high mortality associated with hypercontractility, tachycardia and the presence of a left ventricular obstruction. A severe hypovolemia, a hyper adrenergic stimulation or a severe vasoplegia can all explain this relation between tachycardia, hypercontractility and the mortality during septic shock.
Landiolol is another short-term acting beta-blocker with a half-life of 4 minutes without any beta 2 activity or membrane stabilizing effect. The landiolol has been used in critically ill patients to control supraventricular tachycardia but not in this context of tachycardia and septic shock. The investigators hypothesize that landiolol by reducing the heart rate may improve the survival of patients treated for a septic shock and presenting with an hypercontractility state.
