It has been suggested that the home healthcare nurses use the 'POP' technique to resolve catheter occlusions in Groshong PICCs (attaching an empty syringe to the catheter, pulling back on the plunger to create negative pressure, then releasing the plunger to send a vibration down the line that may breakdown the blockage after multiple pulls). This is in an effort to promptly resolve catheter occlusions in the home rather than waiting for them to be seen by the vascular access service (Alteplase is not available in the home setting due to lack of drug coverage).
The nurses are questioning whether this is best practice. There are 2 articles supporting this. But is there a concern of weakening the catheter wall with all of this manipulation or embolizing the occluding material.
Would appreciate expert opinion and perhaps Bard's representative comments as well.
