LANdiolol MIcrocirculatory Effects During Septic chOc
The objectives of this study are to evaluate the effect of continuous intravenous Landiolol injection (from 0.5 to 10 µg/kg/min during 12 hours ) up to a 15% decrease in Heart Rate (HR) on microcirculatory vascular reactivity vs. usual tachycardia management and evaluate the hemodynamic effects of Landiolol vs. usual management in patients with septic shock.
• Sinus tachycardia not compensatory, if the doctor considers that the heart rate acceleration should be treated.
• The study will be carried out in
• reanimated and stabilized septic shock defined as:
‣ Septic shock is tachycardic (HR\>100/min) patients with sepsis (suspected infection + 2 SOFA points) according to the latest international definition and the need to receive noradrenaline to maintain an average blood pressure above 65 mmHg
⁃ Patient supported for at least 6 hours, necessary for diagnostic management and hemodynamic optimization according to international standards and for less than 24 hours to limit confounding factors related to prolonged reanimation (sedation) and empowerment of organ failure in general and vascular in particular. Hemodynamic stabilization will be defined as the absence of increased doses of norepinephrine in the previous two hours to limit the risk of hypotension induced by Landiolol infusion.
