Patient on continuous renal replacement therapy (crrt), filter changed 3 times in one day.Filer clotted twice immediately after restarting.Patient was on heparin and acid-citrate-dextrose (pre blood pump) as well with no coagulation issues.The third time, restarting crrt had no issues and passed priming test.However, blood leak in the filter was alerted by the machine within 30 mins of restarting it.Pt was unstable while restarting crrt, had episodes of hypoxemic/hypovolemic shock, requiring high dose of vasoactive drugs, intravenous fluids and full ventilator support.Had to stop restarting crrt this time as the patient was not able to tolerate crrt.
