What should I do if picc catheter is blocked?

If it is outside, the extracorporeal catheter should be fixed, and the broken end must not slide in. Be careful not to let air into the catheter, seal it and go to the hospital. If the blockage has entered the body, do not do strenuous exercise, tighten the upper arm to prevent the catheter from slipping deeper and deeper into the heart, and seek medical attention immediately.

1, push the needle back when the last 05 ml is to be changed to pipe flushing.

2. The impulse flushing method was adopted, and the 0.9% sodium chloride injection was at least 10ml syringe, with moderate impulse.

Firstly, make PICC catheter sealing solution: add 1.6 ml heparin sodium into 100 ml physiological saline to make sealing solution containing 100 unit heparin per ml. Then use 2-3 ml heparin saline to seal the tube in pulse mode.

Extended data:

Amount of sealing liquid and sealing time

Rinse the catheter with 5- 10 ml normal saline every 6-8 hours after stopping infusion; 3-5 ml heparin sodium solution, rinse the catheter after infusion, and the anticoagulant effect can last for more than 12 hours. For some patients who are not suitable for heparin sodium and patients with short infusion time, normal saline can be used as tube sealing fluid.

The correct method can prolong the intubation time and prevent complications. Usually, positive pressure is used to seal the tube, and 3 ~ 5ml of tube sealing liquid is slowly injected from the infusion needle in heparin cap, and then the infusion needle is pulled out while pushing the residual liquid, so that the tube sealing liquid fills the whole official cavity (because there is liquid overflowing from the needle tip, it is best to pull out the needle).

Anticoagulation can last for more than 12 hours; For some patients who are not suitable for heparin sodium and patients with short infusion time, normal saline can be used as tube sealing fluid.
