In cases of poor diastolic refilling secondary to hypovolemia, fluid resuscitation plays a crucial role in restoring intravascular volume and improving cardiac performance. Hypovolemia can lead to inadequate cardiac preload, affecting diastolic function (Chen et al., 2021). It is essential to address both absolute and relative hypovolemia to optimize venous return and preload (Ltaief et al., 2022). Aggressive fluid resuscitation is necessary to correct hypovolemia, maintain perfusion, and prevent circulatory dysfunction (Kumar et al., 2018). In conditions like acute pancreatitis, where hypovolemia and microcirculatory dysfunction contribute to poor outcomes, fluid therapy remains a cornerstone of treatment (Bortolotti et al., 2014).
Fluid resuscitation not only corrects hypovolemia but also helps preserve pancreatic microcirculation, preventing complications and disease progression (Abu‐El‐Haija et al., 2018). In the context of cardiac arrest, guidelines recommend using vasopressors and intravenous fluids to manage hypovolemia and maintain adequate blood pressure (Skrifvars, 2021). However, despite fluid resuscitation, poor cardiac output due to diastolic dysfunction can lead to persistent hypotension (Galton et al., 2020).
In various clinical settings, such as severe congestive heart failure or hypovolemia, monitoring central venous pressure and pulmonary artery occlusion pressure can guide fluid therapy to address hypovolemia effectively (Cecconi et al., 2014). Point-of-care ultrasound can aid in identifying signs of hypovolemia, such as small left ventricular end-diastolic diameter and collapsible inferior vena cava, guiding volume administration (Bradley et al., 2023). In trauma patients, vasopressors are essential to maintain target arterial pressure in the presence of myocardial dysfunction (Chandran et al., 2017).
Optimizing fluid resuscitation in cases of hypovolemia secondary to conditions like hemorrhage remains a challenge, emphasizing the importance of tailored approaches to address varying etiologies of hypovolemia (Hundeshagen et al., 2017). Early recognition of hypovolemia through imaging modalities like thoracic radiographs and prompt fluid resuscitation can help stabilize patients with conditions like acute mesenteric ischemia (Hamilton et al., 2010). In emergency departments, assessing fluid volume status is critical to prevent poor outcomes associated with both hypovolemia and fluid overload (Lee et al., 2021).
