fluid challenge

Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.

fluid challenge

The rapid infusion of fluids (crystalloids such as normal saline, or colloids, such as albumin) to resuscitate blood pressure in a patient thought to be hypovolemic.

Patient care

In a typical child 20 mL/kg of normal saline is given intravenously (or intraosseously) over 30 min. The volume infused into an adult is usually 250–1000 mL. The lower volume is used if there are concerns that the patient may develop pulmonary edema. The patient's blood pressure, heart rate and rhythm, oxygenation, and respirations are closely monitored during and after the infusion for evidence of a positive response, e.g., a mean arterial pressure that rises above 70 mm Hg, or deterioration, e.g., increasing dyspnea, ventricular ectopy, or hypoxia. Patients who respond favorably to a fluid challenge are typically placed on a maintenance infusion of fluids to sustain them hemodynamically.

Four out of five patients with FTc less than 350 ms in our study responded to fluid challenge, while all participants with FTc greater than 350 ms were non-responders.
Although BNP greater than 144 pg/ml has previously been posed as a strong predictor of cardiac dysfunction in ICU (13), 42% of patients with BNP above this threshold responded to fluid challenge.
In keeping with previous data, static values of CVP did not predict haemodynamic response to fluid challenge (7).
First of all, the fluid challenge must result in increased cardiac preload.
The clinical relevance of predicting the haemodynamic response to fluid challenge lies in the avoidance of ineffective or deleterious fluid administration (28).
Also, there are scant data regarding the utility of Trendelenburg position in predicting response to fluid challenge.
