Abstract
Background Septic shock is a life-threatening condition characterized by systemic inflammation and organ dysfunction, with fluid resuscitation being a cornerstone of management. However, indiscriminate fluid administration can lead to fluid overload and worsen outcomes. Extravascular lung water (EVLW) estimation by lung ultrasound has emerged as a promising tool for guiding fluid therapy in septic shock, allowing clinicians to assess pulmonary edema and tailor resuscitation strategies accordingly. Methods This prospective observational study aims to evaluate the utility of EVLW estimation by lung ultrasound in guiding fluid resuscitation therapy in adult patients with septic shock admitted to a rural tertiary care teaching hospital. Eligible patients admitted to the intensive care unit (ICU) will undergo baseline demographic and clinical assessments, including lung ultrasound, to quantify EVLW using B-line analysis. Fluid resuscitation therapy will be initiated based on EVLW findings, with subsequent adjustments guided by repeat lung ultrasound examinations at 6, 12, 24, and 48 hours post-initiation. Outcome measures include changes in mean PaO2/FiO2 ratios, respiratory parameters, renal function, fluid balance, and mortality rates. Expected Outcome We anticipate that EVLW-guided fluid resuscitation therapy will lead to more precise and tailored management of septic shock, potentially reducing the incidence of fluid overload, ARDS, and renal dysfunction. By optimizing fluid management strategies based on individual patient characteristics and responses, we aim to improve clinical outcomes and enhance the delivery of care for patients with septic shock.
