Hypervolemia, also known as fluid overload, is the medical condition where there is too much fluid in the blood. The opposite condition is hypovolemia, which is too little fluid volume in the blood. Fluid volume excess in the intravascular compartment occurs due to an increase in total body sodium content and a consequent increase in ...
A patient may be receiving blood due to any number of causes and may have heart or kidney dysfunction which can lead to excess fluid. Upon transfusion of the blood product, the patient is overwhelmed by the excess fluid and develops symptoms related to volume overload. [citation needed]
The development of pulmonary edema may be associated with symptoms and signs of "fluid overload" in the lungs; this is a non-specific term to describe the manifestations of right ventricular failure on the rest of the body.
An imbalance can cause fluid overload in the spaces between cells or tissues, which can lead to edema, per the National Institutes of Health. Edema refers to the swelling that happens when the ...
Heart failure is usually associated with a volume overloaded state. Therefore, those with evidence of fluid overload should be treated initially with intravenous loop diuretics. In the absence of symptomatic low blood pressure intravenous nitroglycerin is often used in addition to diuretic therapy to improve congestive symptoms. [8]
The other causes are usually divided into renal and extrarenal causes. Renal causes include overuse of diuretics, or trauma or disease of the kidney. Extrarenal causes include bleeding, burns, and any causes of edema (e.g. congestive heart failure, liver failure). [citation needed]
Diuretics can be considered for people with evidence of fluid overload, though cautiously used in those with evidence of obstruction. [17] Intravenous phenylephrine (or another pure vasoconstricting agent) can be used in the acute setting of low blood pressure in those with obstructive hypertrophic cardiomyopathy who do not respond to fluid ...
Lack of improvement with fluid resuscitation, therapy-resistant hyperkalemia, metabolic acidosis, or fluid overload may necessitate artificial support in the form of dialysis or hemofiltration. [7] However, oliguria during anesthesia may predict AKI, [34] [35] but the effect of a fluid load is highly variable. Striving toward a predefined urine ...
