The Patient Is a Gravida 6, Para 1

The patient is a gravida 6, para 1.She is admitted after a cesarean section after an amniotic embolus.Her heart rate (HR) is more than 150 beats/min with a systolic BP less than 80 mm Hg.Her temperature is 38°C, and her condition has caused her to develop prerenal azotemia.The patient was fluid resuscitated through a double-lumen catheter, which was placed into her right femoral access, and started on vasopressors with a fair response (BP, 80/50 mm Hg; HR, 122 beats/min) .Because of her diagnosis and a concern regarding fulminating sepsis, the patient was begun on CVVH.Why would this therapy be chosen for this patient?

A) Hyperdynamic patients can better tolerate abrupt fluid and solute changes.
B) It is the treatment of choice for patients with diminished renal perfusion who are unresponsive to diuretics.
C) It is indicated for patients who require large-volume removal for severe uremia or critical acid-base imbalances.
D) It is indicated for hemodynamically unstable patients, who are often intolerant of the abrupt fluid and solute changes that can occur with hemodialysis.
