Infant in severe distributive shock and renal failure was placed on crrt with an hf 20 filter in the early evening.Patient continued to have severe vasodilatory shock requiring fluid administration to maintain hemodynamics.Patient had worsening pulmonary edema and hypoxia as well as st segment changes indicating cardiac distress.In the morning, the patients baxter prismaflex had a self-test failure alert.The alarm was safely over-ridden while another circuit was prepared but was continuing to alarm multiple times while preparing a new circuit.This transition was discussed with the family who requested that we proceed.An hf 1000 was chosen as the filter with the new circuit due to desire to try therapeutic plasma exchange if possible.During the initiation of the new circuit, the patient had a cardiac arrest.Cpr was initiated but discontinued at the parents request.In light of the patients illness and deterioration, changing the circuit did not change the trajectory of this illness and was not the ultimate cause of the patients death.A manufacturer fda urgent medical device correction is in process for the baxter prismaflex machines with the plan to replace the aprs tubing for machines that are experiencing this issue.
