vérvolumenkiegyenlítésre

Vérvolumenkiegészítő (literally “blood volume supplement”) is a term used in medical contexts to refer to interventions designed to increase or maintain intravascular blood volume. Because this exact spelling is not a standard medical term in English, the concept is typically described as blood volume expander or volume resuscitation therapy.

The purpose of a blood volume expander is to restore circulating volume in states of hypovolemia caused by hemorrhage, dehydration, burns, or major surgery, with the aim of improving tissue perfusion and organ function. Expander choices are usually categorized as crystalloids or colloids. Crystalloids (such as normal saline or Ringer’s lactate) quickly distribute beyond the intravascular space, providing rapid volume but with limited intravascular persistence. Colloids (including albumin, dextrans, and hydroxyethyl starch) contain larger molecules that tend to remain longer in the vascular compartment. In many scenarios, blood products may be used to restore oxygen-carrying capacity in addition to volume.

Administration is via intravenous infusion and is guided by clinical signs (blood pressure, heart rate, urine output) and, when available, hemodynamic monitoring. Indications include hypovolemic shock, significant fluid loss from trauma or surgery, and extensive burns. Safety considerations encompass electrolyte disturbances, edema, coagulopathy, transfusion reactions, and fluid overload; the choice of agent depends on patient condition, comorbidities, and clinical goals.

Measurement of blood volume and response to therapy may involve clinical assessment and, in specialized settings, indicator-dilution techniques. If the intended term differs or a specific language form is meant, further clarification can refine the article.
