PICC refers to the placement of central venous catheter through peripheral vein in clinical medicine.PICC flushing is commonly used in two methods: slow flushing and pulsatile. Tube sealing methods include saline, sodium heparin tube sealing and so on.
PICC flushing, if the lumen is not blocked, the flushing can be done by slowly pushing the liquid, the last 0.5 ml, while pushing the needle back. If the lumen is blocked, the tube can be flushed by pulsatile method, paying attention to moderate strength.
Tube sealing method, if it will be used again in a short period of time, simple saline can be used to seal the tube. If the interval is long, you can use prepared heparin sodium solution.
