A Comprehensive Review of Fluid Resuscitation Techniques in Sepsis in Patients with Heart Failure

Introduction: Fluid management in sepsis patients with pre-existing heart failure presents a complex clinical challenge, as these patients require adequate resuscitation while avoiding fluid overload that could worsen cardiac function. This article aims to explore optimal fluid resuscitation strategies for patients with pre-existing heart failure who develop sepsis, a group at high risk for fluid management complications. Methods: We conducted a narrative review of studies published between 2010 and 2024, utilizing PubMed, ScienceDirect, and Google Scholar. We employed Boolean formulas and search terms that evolved from broad to specific, refining the focus on fluid resuscitation in septic heart failure patients. Human studies focusing on fluid resuscitation, sepsis management, and outcomes in heart failure were included. Exclusion criteria included animal studies, non-English articles, and case reports. Results: Guideline-recommended fluid resuscitation (≥30 mL/kg within 3 hours) shows a neutral or positive effect on mortality in sepsis patients with pre-existing heart failure when monitored appropriately. Patients with reduced ejection fraction (HFrEF) and those with preserved ejection fraction (HFpEF) exhibit different tolerances to fluids. Advanced hemodynamic monitoring — including bedside echocardiography, lactate clearance, central venous pressure, and BNP levels — is essential for personalizing fluid therapy. Conclusion: Early guideline-compliant fluid resuscitation followed by a conservative, individualized fluid strategy guided by hemodynamic monitoring optimizes outcomes in sepsis patients with heart failure. Future prospective studies are needed to develop standardized protocols.
