Non-Invasive Cardiometry and Ultrasound Guided Inferior Vena Cava Collapsibility Index in Assessing Fluid Responsiveness

43 patients between 18-60 years presenting with criteria of sepsis (life-threatening organ dysfunction caused by a dysregulated host response to infection, suspected or documented infection and an acute increase ≥2 SOFA \[Sequential Organ Failure Assessment\] points) will be enrolled in our study. Approval of the ethical committee and informed written consent from first degree relatives will be issued. They will be given a full and detailed explanation of the intended study protocol and will be informed about the potential benefits of the development of a successful technique as well as the potential side-effects. To compare the efficacy of non-invasive cardiometry and ultrasound (US) guided inferior vena cava (IVC) collapsibility when assessing the response of septic patients to fluid therapy guidelines of The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3); in the first six hours of ICU admission .
