It was reported that when performing normal pigtail flushing following a lab draw, it was found to be extremely difficult to push back into the circuit.
Clearly some form of obstruction, but did not seem as though there would be clot as the anticoagulation status was adequate, with no other visible signs of clots noted throughout the circuit.
For fear of there being a clot, the process was discontinued.
Without this finding communicated further, some days later, the nurse found that though there was resistance, the port flushed to the circuit.
With a subsequent attempt a few hours later to do maintenance flushing by the same nurse, it was found that the port would again, not flush to the circuit.
So there would be times when the valve would seem compromised in a way allowing the ability to flush to the circuit, and then at times, the integrity of the valve was recaptured and then did not allow for flushing.
The plan was to possibly have the ecmo system removed soon, so the hope is to leave the device until removal, and will be shipped back to abbott.
The patient has been extubated since on the device, and is seemingly doing quite well currently.
