Recently, the PICC of an old granny in the author's department could not be
extracted from the blood, and there was no response to the nudge. The author's
department rarely encountered PICC, which made us puzzled. We immediately
consulted the PICC clinic, and after guidance, we finally dredge it, and then
Shared our experience with you.
Items needed: one tee, two 20ml syringes, urokinase, saline.
Usage (full blocked tube) : apply 20ml normal saline to 100,000 units of
urokinase (concentration: 5000 units /ml), extract 10ml of the configured
urokinase with a 20ml syringe, connect the tee correctly, connect the straight
end to urokinase, and connect the side of the tee to an empty 20ml syringe. Turn
the tee to the end of the empty syringe, fix the syringe with one hand, and draw
back the syringe with the other hand repeatedly to form negative pressure. Turn
the tee to the other side under negative pressure.
PICC half blocking pipe processing methods: 100000 units of urokinase with
20 ml diluted saline (5000 units/ml), with 20 ml syringe 1 ml urokinase
injection intraductal, half an hour to smoke, if did not see h. smoke once every
1 hours back, until see h., returned to take more than 1 ml of blood abandon
(including urokinase) in the blood, the correct wash pipe and tube.
